Full Text Description
l-PHENYL- AND 1-PYRIDYLPYRAZOLE DERIVATIVES AND THEIR USE AS PESTICIDES
The invention relates to 1-(2,4,6-trisubstituted-phenyl)-5-amino-4-substitutedpyrazole
derivatives, processes for their preparation, to compositions thereof, and
to their use for the control of pests (including arthropods like insects and arachnids)
and helminths (including nematodes).
The control of insects, arachnids and helminths with 1 -arylpyrazole compounds has
been described in, for example, patent publication numbers WO 87/03781, EP
0295117, WO98/28279 and WO 98/24769.
Since modern pesticides must meet a wide range of demands, for example
regarding level, duration and spectrum of action, use spectrum, toxicity,
combination with other active substances, combination with formulation auxiliaries
or synthesis, and since the occurrence of resistance is possible, the development
of such substances can never be regarded as concluded, and there is constantly a
high demand for novel compounds which are advantageous over the known
compounds, at least as far as some aspects are concerned.
It is an object of the present invention to provide new pesticides which may be used
in domestic companion animals. n
It is advantageous to apply pesticides to animals in oral form so as to prevent the
possible contamination of humans or the surrounding environment.
Another object of the invention is to provide new pesticides which may be used in
lower dose than existing pesticides.
Another object of the invention is to provide new pesticides which are substantially
non-emetic.
Another object of the invention is to provide new pestte^
user and the environment
These objects are met in whole or in part by the present invention.
The present invention provides a compound which is a 1-(2,4,6-trisubstitutedphenyl)-
5-amino-4-ha!oalkylthiopyrazoIe derivative of formula (I):

Collections of compounds of the formula (I) which can be synthesized by the above
mentioned process may also be prepared in a parallel manner, and this may be
effected manually or in a semiautomated or fully automated manner. In this case, it
is possible, for example, to automate the procedure of the reaction, work-up or
purification of the products or of the intermediates. In total, this is to be understood
as meaning a procedure as is described, for example, by S.H. DfeWitt in "Annual
Reports in Combinatorial Chemistry and Molecular Diversity: Automated
Synthesis", Volume 1, Verlag Escom 1997, pages 69 to 77.
A series of commercially available apparatuses as are offered by, for example,
Stem Corporation, Woodrplfe Road, Tollesbury, Essex, GM9 8SE, England or H+P
Labprtechnik GmbH, Bruckrnannring 28, 85764 OberschleiSheim, Germany or
Radleys, Shirehill,. Saffggn^WjIderjtr E^sSexr England, may be'used for the'para lief-*1
procedure of the reaction and work-up. For the parallel purificatiorTdf compounds of
the formula (I), or of intermediates obtained during the preparation, use may be
made, inter alia, of ehromatography apparatuses, for example those by ISCO, Inc.,
4700 Superior Street, Lincoln, NE 68504, USA.
The apparatuses mentioned lead to a modular procedure in which the individual
process steps are automated, but manual operations must be performed between
the process steps. This can be prevented by employing semi-integrated or fully
integrated automation systems where the automation modules in question are
operated by, for example, robots. Such automation systems can be obtained, for
example, from Zymark Corporation, Zymark Center, Hopkinton, MA 01748, USA.
In addition to what has been described here, compounds of the formula (I) may be
prepared in part or fully by soiid-phase-supported methods. For this purpose,
individual intermediate steps or all intermediate steps of the synthesis or of a
synthesis adapted to suit the procedure in question are bound to a synthetic resin.
Solid-phase-supported synthesis methods are described extensively in the
specialist literature, for example Barry A. Bunin in "The Combinatorial Index",
Academic Press, 1998.
The use of solid-phase-supported synthesis methods permits a series of protocols
which are known from the literature and which; in turn, can be performed manually
or in an automated manner. For example, the "tea-bag method" (Houghten, US
4,631,211; Houghten et al., Proc. Natl. Acad. Sci, 1985, 82, 5131-5135), in whTeh
products by IRQRI, 11149 North Torrey Pines Road, La Jolla, CA 92037, USA, are
employed, may be semiautomated. The automation of solid-phase-supported
parallel syntheses is performed successfullyy for example, by apparatuses by
Argonaut Technologies, Inc., 887 Industrial Road, San Carlos, CA 94070, USA or
MultiSynTech GmbH, Wullener Feld 4, 58454 Witten, Germany.
The preparation of the processes described herein yields compounds of the
formula (I) in the form of substance collections which are termed libraries'. The
present invention also provides fon to libraries which comprise 'at least two
compounds of the formula (I).

C6)-haloalkoxy or (CrC6)-haloalkylthio, and compounds of formula (IV) wherein L1
is chlorine and X is NR6aR7a, (CrCeJ-alkoxy, (C-C6)-haloalkoxy or (Cr
C6)-haloalkylthio also fall within the definition of formula (I).
Compounds of formula (III), (V), (VI), (VII), (VIII), (IX), (X), (XI) and (XII), as well as
certain compounds of formula (II) and (IV) are known or may be prepared by known
methods.

According to a further feature of the present invention there is provided a method
for the control of pests at a locus which comprises applying thereto an effective
amount of a compound of formula (I) or a salt thereof. For this purpose, the said
compound is normally used in the form of a pesticidal composition (i.e. in
association with compatible diluents or carriers and/or surface active agents
suitable for use in pesticidal compositions), for example as hereinafter described.
The term "compound of the invention" as used hereinafter embraces a 1 -(2,4,6-
trisubstituted-phenyl)-5-amino-4-substituted-pyrazole of formula (I) as defined
above and a pesticidally acceptable salt thereof.
One aspect of the present invention as defined above is a method for the control of
pests at a locus. The locus includes, for example, the pest itself, the place (plant,
field, forest, orchard, waterway, soil, plant product, or the like) where the pest
resides or feeds, or 9 place susceptible to future infestation by the pest The
compound of the invention may therefore be applied directly to the pest, to the
place where the pest resides or feeds, or to the place susceptible to future
infestation by the pest.
As is evident from the foregoing pesticidal uses, the present invention provides
pesticidally active compounds and methods of use of said compounds for the
control of a number of pest species which includes: arthropods, especially insects
or mites, or plant nematodes. The compound of the invention may thus be
advantageously employed in practical uses, for example, in agricultural or
horticultural crops, in forestry, in veterinary medicine or livestock husbandry, or in
public health.
The compounds of the mverjon may be used for example in the following 1 ' applications and on the following pests

For the control of soil insects, such as corn rootworm, termites (especially for
protection of structures), root maggots, wireworms, root weevils, stalkborers,
cutworms, root aphids, or grubs. They may also be used to provide activity against
plant pathogenic nematodes, such as root-knot, cyst, dagger, lesion, or stem or
bulb nematodes, or against mites. For the control of soil pests, for example corn
rootworm, the compounds are advantageously applied to or incorporated at an
effective rate into the soil in which crops are planted or to be planted or to the
seeds or growing plant roots.
In the area of public health, the compounds are especially useful in the control of
many insects, especially filth flies or other Dipteran pests, such as houseflies,
stableflies, soldierflies> hornflies, deerflies, horseflies, midges, punkies, blackflies,
or mosquitoes.
In the protection of stored products, for example cereals, including grain or flour,
groundnuts, animal feedstuffs, timber or household goods, e.g. carpets and textiles,
compounds of the invention are useful against attack by arthropods, more
especially beetles, including weevils, moths ormites^ for example Ephestia spp.
(flour moths), Anthrenus spp. (carpet beetles), Tribolium spp: (flour beetles),
Sitophilus spp. (grain weevils) or Acarus spp. (mites).
In the control of cockroaches, ants or termites or similar arthropod pests in infested
domestic or Industrial premises or in the control of mosquito larvae in waterways,
wells, reservoirs or other running or standing water.

forestry or horticulture either directly or by spreading bacterial-viral, mycoplasma or
fungal diseases of the plants. For example root-knot nematodes such as
Meloidogyne spp. (e.g. M. incognita).
In the field of veterinary medicine or livestock husbandry or in the maintenance of
public health against arthropods which are parasitic internally or externally upon
vertebrates, particularly warm-blooded vertebrates, for example domestic animals,
e.g. cattle, sheep, goats, equines, swine, poultry, dogs or cats, for example
Acarina, including ticks (e.g. soft-bodied ticks including Argasidae spp. e.g. Argas
spp. and Ornithodorus spp. (e.g. Ornithodorus moubata); hard-bodied ticks
including Ixodidae spp., e.g. Boophilus spp, e.g. Boophilus micropliis,

sanguineus; mites (e.g. Damalinia spp.); fleas (e.g. Ctenocephalides spp. e.g.
Ctenocephaljdes felis (cat flea) and Gtenocephalides canis (dog flea)); lice e.g. ~
Menopon spp.; Diptera (e.g. Aedes spp., Anopheles spp./ Musca spp., Hypodeima
spp.); Hemiptera.; Dictyoptera (e.g. Periplaneta spp., Blatella spp.); Hymenoptera;
for example against infections of the gastro-intestinal tract caused by parasitic
nematode worms, for example members of the family Trichostrongylidae.
In a preferred aspect of the invention the compounds of formula (I) are used for the
control of parasites of animals. Preferably the animal to be treated is a domestic
companion animal such as:a dog OF.a cafc
In a further aspect of the invention the compounds of formula (I) or salts or
compositions thereof are used for the preparation of a veterinary medicament.
A further feature of the invention thus relates to the use of a compound of formula
(I) or a salt thereof, or of a composition thereof, for the control of pests.
In practical use for the control of arthropods, especially insects or mites, or
helminths, especially nematode pests of plants, a method, for example, comprises
applying to the plants or to the medium in which they grow an effective amount of a
compound of the invention. For such a method, the compound of the invention is
generally applied to the locus in which the arthropod or nematode infestation is tobe
controlled at an effective rate in the range of about 2g to about 1kg of the active
compound per hectare of locus treated. Under ideal conditions, depending on the
pest to be controlled, a lower rate may offer adequate protection. On the other
hand, adverse weather conditions, resistance of the pest or other factors may
require that the active ingredient be used at higher rates. The optimum rate
depends usually upon a number of factors, for example; the type of pest being
controlled, the type or the growth stage of the infested plant, the row spacing or
also the method of application. Preferably an effective rate range of the active
compound is from about 10g/ha to about 400g/ha, more preferably from about
50g/ha to about 200 g/ha.
When a pest is soil-borne, the active compound generally in a formulated
composition* is distributed evenly over the area to be treated (ie^ for example
broadcast or band treatment) in any convenient manner and is applied at rates from
about 10g/ha to about 400g ai/ha, preferably from about 50g/ha to about 200 g
ai/ha. When applied as a root dip to seedlings or drip irrigation to plants the liquid
solution or suspension contains from about 0.075 to about 1000 mg ai/l, preferably
from about 25 to about 200 mg ai/l. Application may be made, if desired, to the
field or crop-growing area generally or in close proximity to the seed or plant to be
protected from attack. The compound of the invention can be washed into the soil
by spjayjng.with water over the,.area or can be left to the natural action of rainfall.
During, or after application, the formulated compound1 can] if desired, be distributed
46
mechanically in the soil, for example by ploughing, disking, or use of drag chains.
Application can be prior to planting, at planting, after planting but before, sprouting
has taken place, or after sprouting.
The compound of the invention and methods of control of pests therewith are of
particular value in the protection of field, forage, plantation, glasshouse, orchard or
vineyard crops, of ornamentals, or of plantation or forest trees, for example: cereals
(such as wheat or rice), cotton, vegetables (such as peppers), field crops (such as
sugar beets, soybeans or oil seed rape), grassland or forage crops (such as maize
or sorghum), orchards or groves (such as of stone or pit fruit or citrus), ornamental
plants, flowers or vegetables or shrubs under glass or in gardens or parks, or forest
trees (both deciduous and evergreen) in forests, plantations or nurseries.
They are also valuable in the protection of timber (standing, felled, converted,
stored or structural) from attack, for example, by sawflies or beetles or termites.
They have applications in the protection of stored products such as grains, fruits,
nuts, spices or tobacco, whether whole, milled or compounded into products, from
moth, beetle, mite or grain weevil attack. Also protected are stored animal products
such as skins, hair, wool or feathers in natural or converted form (e.g. as carpets or
textiles) from moth or beetle attack as well as stored meat, fish or grains from
beetle, mite or fly attack.
Additionally, the compound of the invention and methods of use thereof are of
particular value in the control of arthropods or helminths which are injurious to, or
spread or act as vectors of diseases domestic animals, for example those
hereinbefore mentioned, and more especially in the control of ticks, mites, lice,
fleaSj midges, or biting, nuisance or myiasis flies. The compounds of the invention
are particularly useful jn controlling arthropods or helminths which are present
inside domestic host animals or which feed in or on the skin or suck the blood of
the animal, for which purpose they may be administered orally, parenterally,
percutaneously or topically.
The compositions hereinafter described for application to growing crops or crop
growing loci or as a seed dressing may, in general, alternatively be employed in the
protection^of stored products,-household goods,- property or areas of the general
environment. Suitable means oftapplying the compounds of the invention include:
to growing crops as foliar sprays (for example as an in-furrow spray), dusts,
granules, fogs or foams or also as suspensions of finely divided or encapsulated
compositions as soil or root treatments by liquid drenches, dusts, granules, smokes
or foams; to seeds of crops via application as seed dressings, e.g. by liquid slurries
or dusts;
to animals infested by or exposed to infestation by arthropods or helminths, by
parenteral, oral or topical application of compositions in which the active ingredient
exhibits an immediate and/or prolonged action over a period of time against the
arthropods or helminths, for example by incorporation in feed or suitable orallyingestible
pharmaceutical formulations, edible baits, salt licks, dietary supplements,
pour-on formulations, sprays, baths, dips, showers, jets, dusts, greases, shampoos,
creams, wax smears or livestock self-treatment systems;
to the environment in general or to specific locations where pests may lurk,
including stored products, timber, household goods, or domestic or industrial
premises, as sprays, fogs, dusts, smokes, wax-smears, lacquers, granules or baits,
or in tricklefeeds to waterways, wells, reservoirs or other running or standing water.
The compounds of formula (I) are particularly useful for the control of parasites of
animals when applied orally, and in a further preferred aspect of the invention the
compounds of formula (I) are used for the control of parasites of animals by oral
application. The compounds of the formula (I) or salts thereof may be administered
before, during or after meals, The compounds of the formula (I) or salts thereof may
be mixed with a carrier and/or foodstuff./ '
The compound of the formula (I) or salt thereof is administered orally in a dose to
the animal in a dose range generally from 0.1 to 500 mg/kg of the compound of the
formula (I) or salt thereof per kilogram of animal body weight (mg/kg).
The frequency of treatment of the animal, preferably the domestic animal to be
treated by the compound of the formula (I) or salt thereof is generally from about
once per week to about once per year, preferably from about once every two weeks
to once every three months.
The compounds of the invention may be administered most advantageously with
another parasiticidalfy effective material, such as an endoparasiticide, and/or an
ectoparasiticide, and/or an endectoparasiticide. For example, such compounds
include macrocyclic lactones such as avermectins or milbemycins e.g., ivermectin,
pyratel or an insect growth regulator such as lufenuron or methoprene.
The compounds of the formula (I) can also be employed for controlling harmful
organisms in crops of known genetically engineered plants or genetically
engineered plants yet to be developed. As a rule, the transgenic plants are
distinguished by especially advantageous properties, for example by resistances to
particular crop protection agents, resistances to plant diseases or pathogens of
plant diseases, such as particular insects or microorganisms such as fungi, bacteria
or viruses. Other particular properties concern, for example, the harvested material
with regard to quantity, quality, storage properties, composition and specific
constituents. Thus, transgenic plants are known where the starch content is
increased, or the starch quality is altered, or where the harvested material has a
different fatty acid composition.
The use in economically important transgenic crops of useful plants and
ornamentals is preferred, for example of cereals such as wheat, barley, rye, oats,
millet, rice, cassava and maize or else crops of sugar beet, cotton, soya, oilseed
rape, potatoes, tomatoes, peas and other types of vegetables.
When used in transgenic crops, in particular those which have resistances to
insects, effects are frequently observed, in addition to the effects against harmful
organisms to be observed in other crops, which are specific for application in the
transgenic crop in question, for example an altered or specifically widened
spectrum of pests which can be controlled, or altered application rates which may
be employed for application.
The invention therefore also relates to the use of compounds of the formula (I) for
controlling harmful organisms in transgenic crop plants.
According to a further feature of the present invention there is provided a pesticidal
composition comprising one or more compounds of the invention as defined above,
in association with, and preferably homogeneously dispersed in one or more
compatible pesticidally acceptable diluents or carriers and/or surface active agents
[i.e. diluents or carriers and/or surface active agents of the type generally accepted
in the art as being suitable for use in pesticidal compositions and which are
compatible with compounds of the invention].
In practice, the compounds of the invention most frequently form parts of
compositions. These compositions can be employed to control arthropods,
especially insects, or plant nematodes or mites. The compositions may be of any
type known in the art suitable for application to the desired pest in any premises or
indoor or outdoor area. These compositions contain at least one compound of the
invention as the active ingredient in combination or association with one or more
other compatible components which are for example, solid or liquid carriers or
diluents, adjuvants, surface-active-agents, or the like appropriate for the intended
use and which are agronomically or medicinally acceptable. These compositions,
which may be prepared by any manner known in the art, likewise form a part of this
invention.
The compounds of the invention, in their commercially available formulations and in
the use forms prepared from these formulations may be present in mixtures with
other active substances such as insecticides, attractants, sterilants, acaricides,
nematicides, fungicides, growth regulatory substances or herbicides.

The abovementioned components for combinations are known active substances,
many of which are described in Ch.R Worthing, S.B. Walker, The Pesticide Manual,
12th Edition, British Crop Protection Council, Farnham 2000.
The effective use doses of the compounds employed in the invention can vary
within wide limits, particularly depending on the nature of the pest to be eliminated
or degree of infestation, for example, of crops with these pests. In general, the
compositions according to the invention usually contain about 0.05 to about 95%
(by weight) of one or more active ingredients according to the invention, about 1 to
about 95% of one or more solid or liquid carriers and, optionally, about 0.1 to about
50% of one or more other compatible components, such as surface-active agents
or the like.
In the present account, the term "carrier" denotes an organic or inorganic
ingredient, natural or synthetic, with which the active ingredient is combined to
facilitate its application, for example, to the plant, to seeds or to the soil. This
carrier is therefore generally inert and it must be acceptable (for example,
agronomically acceptable, particularly to the treated plant).
The carrier may be a solid, for example, claysy natural or synthetic silicates, silica/
resins, waxes, solid fertilizers (for example ammonium salts), ground natural
minerals, such as kaolins, clays, talc, chalk, quartz, attapulgite, montmorillonite,
bentonite or djatomaceous earth, or ground synthetic minerals, such as silica,
alumina, or silicates especially aluminium or magnesium silicates. As solid carriers
for granules the following are suitable: crushed or fractionated natural rocks such
as calcite, marble, pumice, sepiolite and dolomite; synthetic granules of inorganic
or organic meals; granules of organic material such as sawdust, coconut shells,
corn cobs, corn husks or tobacco stalks; kieselguhr, tricalcium phosphate,
powdered cork?,or absorbent carbon black,'-water-soluble polyrriers/resins, waxes
A * i or solid fertilizers. Such solid compositions"may, if desired, contain one or more
compatible wetting, dispersing, emulsifying or colouring agents which, when solid,
may also serve as a diluent.
The carrier may also be liquid, for example: water; alcohols, particularly butanol or
glycol, as well as their ethers or esters, particularly methylglycol acetate; ketones,
particularly acetone, cyclohexanone, methylethyl ketone, methylisobutylketone, or
isophorone; petroleum fractions such as paraffinic or aromatic hydrocarbons,
particularly xylenes or alkyl naphthalenes; mineral or vegetable oils; aliphatic
chlorinated hydrocarbons, particularly trichloroethane or methylene chloride;
aromatic chlorinated hydrocarbons, particularly chlorobenzenes; water-soluble or
strongly polar solvents such as dimethylformamide, dimethyl sulphoxide, or Nmethylpyrrolidone;
liquefied gases; or the like or a mixture thereof.
The surface-active agent may be an emulsifying agent, dispersing agent or wetting
agent of the ionic or non-ionic type or a mixture of such surface-active agents.
Amongst these are e.g., salts of polyacrylic acids, salts of lignosulphonic acids,
salts of phenolsulphonic or naphthalenesulphonic acids, polycondensates of
ethylene oxide with fatty alcohols or fatty acids or fatty esters or fatty amines,
substituted phenols (particularly alkylphenols or arylphenols), salts of
sulphosuccinic acid esters, taurine derivatives (particularly alkyltaurates),
phosphoric esters of alcohols or of polycondensates of ethylene oxide with phenols,
esters of fatty acids with pplyols, or sulphate, sulphonate or phosphate functional
derivatives of the above compounds. The presence of at least one surface-active
agent is generally essential when the active ingredient and/or the inert carrier are
only slightly water soluble or are not water soluble and the carrier agent of the
composition for application is water: •
Compositions of the invention may further contain other additives such as
adhesives or colorants. Adhesives such as carboxymethylcellulose or natural or
synthetic polymers in the form of powders, granules or lattices, such as arabic gum,
polyvinyl alcohol or polyvjnyl acetate, natural phospholipids, such as cephalins or
lecithins, or synthetic phospholipids can be used in the formulations. It is possible
to use colorants such as inorganic pigments, for example: iron oxides, titanium
oxides p^rPrussian^Blue^ organic dyestuffs, such as, alizarin dyestuffs, azo dyestuffs
or metal phthalocyanine dyestuffs; or trace nutrients such as salts of i ron,
manganese, boron, copper, cobalt, molybdenum or zinc.
For their agricultural application, the compounds of the invention are therefore
generally in the form of compositions, which are in various solid or liquid forms.
Solid forms of compositions which can be used are dusting powders (with a content
of the compound of the invention, ranging up to 80%), wettable powders or
granules (including water dispersible granules), particularly those obtained by
extrusion, compacting, impregnation of a granular carrier, or granulation starting
from a powder (the content of the compound of the invention, in these wettable
powders or granules being between about 0.5 and about 80%). Solid homogenous
or heterogenous compositions containing one or more compounds of the invention,
for example granules, pellets, briquettes or capsules, may be used to treat standing
or running water over a period of time. A similar effect may be achieved using
trickle or intermittent feeds of water dispersible concentrates as described herein.
Liquid compositions, for example, include aqueous or non-aqueous solutions or
suspensions (such as emulsifiable concentrates, emulsions, flowables, dispersions,
or solutions) or aerosols. Liquid compositions also include, in particular,
emulsifiable concentrates, dispersions, emulsions, flowables, aerosols, wettable
powders (or powder for spraying), dry flowables or pastes as forms of com positions
which are liquid or intended to form liquid compositions when applied, for example
as aqueous sprays (including low and ultra-low volume) or as fogs or aerosols.
Liquid compositions,;for example, in the form of emulsifiable or soluble
concentrates most frequently comprise about 5 to about 80% by weig tit of the
active ingredient, while the emulsions or solutions which are ready for application
contain, in their case, about 0.01 to about 20% of the active ingredient. Besides
the solvent, the emulsifiable or soluble concentrates may contain, when required,
about 2 to about 50% of suitable additives, such as stabilizers, surface-active
agents, penetrating agents, corrosion inhibitors; colorants or adhesives. Emulsions
of any required concentration, which are particularly suitable for application, for
example, to plants, may be obtained from these concentrates'by dilution with water.
These compositions are included.,within the scope'of the compositions which may'-
be employed in the present invention. The emulsions may be in the form of waterin-
oil or oil-in-water type and they may have a thick consistency.
The liquid compositions of this invention may, in addition to normal agricultural use
applications be used for example to treat substrates or sites infested or liable to
infestation by arthropods (or other pests controlled by compounds of this invention)
including premises, outdoor or indoor storage or processing areas, containers or
equipment or standing or running water.
All these aqueous dispersions or emulsions or spraying mixtures can be applied,
for example, to crops by any suitable means, chiefly by spraying, at rates which are
generally of the order of about 100 to about 1,200 liters of spraying mixture per
hectare, but may be higher or lower (eg. low or ultra-low volume) depending upon
the need or application technique. The compound or compositions according to the
invention are conveniently applied to vegetation and in particular to roots or leaves
having pests to be eliminated. Another method of application of the compounds or
compositions according to the invention is by chemigation, that is to say, the
addition of a formulation containing the active ingredient to irrigation water. This
irrigation may be sprinkler irrigation for foliar pesticides or it can be ground irrigation
or underground irrigation for soil or for systemic pesticides.
The concentrated suspensions; which can be applied by spraying, are prepared so
as to produce a stable fluid product which does not settle (fine grinding) and usually
contain from about 10 to about 75% by weight of active ingredient, from about 0.5
to about 30% of surface-active agents, from about 0.1 to about 10% of thixotropic
agents, from about 0 to about 30% of suitable additives, such as anti-foaming
agents, corrosion inhibitors, stabilizers, penetrating agents, adhesives and, as the
carrier, water or an organic liquid in which the active ingredient is poorly soluble or
insoluble Some organic solids or inorganic salts may be dissolved in the carrierto
help prevent settling or as antifreezes for water.
The wettable powers (or powder for spraying) are usually prepared so that they
contain from about 10 to about 80%: by weight of active ingredient, from about20 to
about 90% of a solid carrier, from about 0 to about 5% of a wetting agent, from
about 3jLo about 10% of a dispersing.agent and,, when- necessary, from about 0 to
about80% of one or more stabilizers and/or otheradditives, such" as penetrating56
agents, adhesives, anti-caking agents, colorants, or the like. To obtain these
wettable powders, the active ingredient is thoroughly mixed in a suitable blender
with additional substances which may be impregnated on the porous filler and is '
ground using a mill or other suitable grinder. This produces wettable powders, the
wettability and the suspendability of which are advantageous. They may be
suspended in water to give any desired concentration and this suspension can be
employed very advantageously in particular for application to plant foliage.
The "water dispersible granules (WG)" (granules which are readily dispersible in
water) have compositions which are substantially close to that of the wettable
powders. They may be prepared by granulation of formulations described for the
wettable powders, either by a wet route (contacting finely divided active ingredient
with the inert filler and a little water, e.g. 1 to 20% by weight, or with an aqueous
solution of a dispersing agent or binder, followed by drying and screening), or by a
dry route (compacting followed by grinding and screening).
The rates and concentrations of the formulated compositions may vary according to
the method of application or the nature of the compositions or use thereof.
Generally speaking, the compositions for application to control arthropod or plant
nematode pests usually contain from about 0.00001% to about 95%, more
particularly from about 0.0005% to about 50% by weight of one or more
compounds of the invention, or of total active ingredients (that is to say the
compounds of the invention, together with other substances toxic to arthropods or
plant nematodes, synergists, trace elements or stabilizers). The actual
compositions employed and their rate of application will be selected to achieve the
desired effect(s) by the farmer, livestock producer, medical or veterinary
practitioner, pest control operator or other person skilled in the art.
Solid or liquid compositions for application topically to animals, timber, stored
products or household goods usually contain from about 0.00005% to about 90%,
more particularly from about 0.001 % to about 10%, by weight of one or more
compounds of the invention. For administration to animals orally or parenterally,
including percutaneously solid or liquid compositions, these normally contain from
about p. l°/q to about 9,0% by weight of one or mora compounds of- the invention:
Medicate,ct feedstuffs, normally'contain from about 0.001% to ab'o'ut 3% by weight of
one or more compounds of the invention. Concentrates or supplements for mixing
with feedstuffs normally contain from about 5% to about 90%, preferably from about
5% to about 50%, by weight of one or more compounds of the invention. Mineral
salt licks normally contain from about 0.1 % to about 10% by weight of one or more
compounds of formula (I) or pesticidally acceptable salts thereof.
Dusts or liquid compositions for application to livestock, goods, premises or outdoor
areas may contain from about 0.0001% to about 15%, more especially from about
0.005% to about 2.0%, by weight, of one or more compounds of the invention.
Suitable concentrations in treated waters are between about 0.0001 ppm and about
20 ppm, more particularly about 0.001 ppm to about 5.0 ppm. of one or more
compounds of the invention, and may be used therapeutically in fish farming with
appropriate exposure times. Edible baits may contain from about 0.01 % to about
5%, preferably from about 0.01 % to about 1.0%, by weight, of one or more
compounds of the invention.
When administered to vertebrates parenterally, orally or by percutaneous or other
means, the dosage of compounds of the invention, will depend upon the species,
age, or health of the vertebrate and upon the nature and degree of its actual or
potential infestation by arthropod or helminth pests. A single dose of about 0.1 to
about 100 mg, preferably about 2.0 to about 20.0 mg, per kg body weight of the
animal or doses of about 0.01 to abqut 20-0 rng, preferably about 0.1 to about 5.0
mg, per kg body weight of the animal per day, for sustained medication, are
generally suitable by oral or parenteral administration. By use of sustained release
formulations or devices, the daily doses required over a period of months may be
combined and administered to^^ animals on g single ocpasion.

METHODS OF PESTiCIDAL USE
The following representative test procedures, using compounds of the
invention, were conducted to determine the parasiticidal and insecticidal activity of"
the compounds of the invention.
Biological Examples
Method A: Screening method to test systemicity of compounds against
Ctenpcephalides felis (Gat flea)
A test container was filled with 10 adults of Ctenocephalides felis. A glass cylinder
was closed on one end with parafilm and placed on top of the test container. The
test compound solution was then pipetted into bovine blood and added to the glass
cylinder. The treated Ctenocephalides felis were held in this artificial dog test (blood
37 °C, 40-60 % relative humidity; Ctenocephalides felis 20-22°C, 40-60 % relative
humidity) and assessment performed at 24 and 48 hours after application.

90% control of Ctenocephalides felis at a test concentration of 5ppm or less.
Method B: Screening method to test contact activity of compounds against
Ctenocephalides felis (Cat flea)
Solutions of the test compounds were dropped onto filter paper, dried and the filter
paper placed into test tubes and infested with 10 adults of Ctenocephalides felis.
The treated Ctenocephalides felis were held in a climate chamber (26°C, 80% RH)
and the percentage efficacy assessed 24 hours and 48 hours after application in
comparison with the untreated control/
Compound numbers 1-04, 2-01 and 2-O4 gave at least 70% contact control of
Ctenocephalides felis at a test concentration of 1000 ppm.
Method C: Screening method to test contact activity against Rhipicephalus
sanguineus (Brown dbg tick)
Solutions of the test compounds were d ropped onto.filter paper, dried and the filter
paper placed into test tubes and infested with 20-30 iarvae'(L1) of Rhipicephalus" :
sanguineus and the tubes closed with a clip. The treated Rhipicephalus sanguineus
were held in a climate chamber (25°C, 90% RH) and the percentage efficacy
assessed 24 hours after application in comparison with the untreated control.
Compound numbers 1-04, 1-10, 2-01, 2-04 and 9-05 gave at least 70% contact
control of Rhipicephalus sanguineus at a test concentration of 100 ppm.
Method D: Diabrotica undecimpunctata (southern corn rootworm) screen
Two days before application, seeds of maize were soaked in water under warm
conditions to elicit fast germination. One day before application, eggs of Diabrotica
undecimpunctata were transferred to one half of a Japanese filter paper placed in a
plastic petri dish. Afterwards, a sprouted maize seed was placed on a moistened
pad beside the filter paper. Three drops of 200 microlitres of test compound
solution were carefully pipetted onto the egg. The remainder of the solution was
placed on the maize and then the Petri dish was closed. The treated eggs in the
Petri dishes were held in a climate chamber for 6 days: The compound efficacy
(percentage of dead eggs and/or larvae in comparison to untreated control) was
assessed 6 days after application using a binocular microscope.
Compound numbers 1-31, 9-04, 9-05 and 9-09 gave at least 90% control of
Diabrotica undecimpunctata at a test concentration of 10ppm.
Method E: Nilaparvata lugens (Rice brown planthopper) screen
The leaves of rice plants were dipped for 5 seconds into an aqueous solution of the
formulated preparation to be examined. After the solution had run off, the rice
plants were placed in a Petri dish and populated with about 20 larvae (L3 stage) of
the rice leafhopper species Nilaparvata lugens. The Petri dish was closed and then
stored in a climatized chamber (16 hours of light/day, 25°C, 40 - 60% relative
atmospheric humidity). After 6 days storage, the mortality among the leafhopper
larvae was determined.
Compound numbers 9-04, 9-05, 9-07, 9-09, 9-25 and 9-26 gave at least 90%
control of Nilaparvata lugens at a test concentration of lOpprrK';
