In the literature, certain methoxyacrylic acid derivatives are proposed as active ingredients
of pesticidal compositions. The biological properties of those known compounds are not,
however, entirely satisfactory in the field of pest control and there is therefore a need to
make available other compounds having pesticidal properties, especially for controlling
insects and representatives of the order Acarina and especially also for controlling
phytopathogenic microorganisms, that problem being solved according to the invention by
the provision of the present compounds of formula I.
Some of the compounds of formula I contain asymmetric carbon atoms, with the result that
those compounds can occur in optically active form. Owing to the presence of the C=X and
oximino double bonds, the compounds can occur in the form of E isomers and Z isomers.
Atropisomerism of the compounds may also occur. Formula I is intended to include all those
possible isomeric forms, and mixtures thereof, for example racemates or mixtures of
E/Z isomers.
Unless otherwise defined, the general terms used hereinbefore and hereinafter have the
following meanings.

up to and including 8, preferably from 1 up to and including 6, especially from 1 up to and
including 4 and above all 1 or 2, carbon atoms.
Alkyl, both as a group perse and as a structural element of other groups and compounds,
such as haloalkyl, alkoxy and alkylthio, is, in each case taking due account of the number of
carbon atoms contained in the corresponding group or compound, either straight-chained,
i.e. methyl, ethyl, propyl, butyl, pentyl or hexyl, or branched, e.g. isopropyl, isobutyl, secbutyl,

contained in the corresponding group or compound, either straight-chained, such as vinyl,
1-methylvinyl, allyl, 1-butenyl or2-hexenyl, or branched, such as isopropenyl.
Alkynyl, both as a group perse and as a stuctural element of other groups and compounds,
such as haloalkynyl, is, in each case taking due account of the number of carbon atoms

the corresponding compound, either straight-chained, such as propargylene, 2-butynylene
or 5-hexynylene, or branched, e.g. 2-ethynylpropylene or 2-propargylisopropylene.
Aryl is phenyl or naphthyl, especially phenyl.
Heterocyclyl denotes a 5- to 7-membered aromatic or non-aromatic ring having from one to
three hetero atoms selected from the group consisting of N, O and S. Preference is given to

scope of the invention to agrochemically advantageous salts. In view of the close
relationship between the compounds of formula I in free form and in the form of their salts,
any reference hereinbefore or hereinafter to the compounds of formula I is to be understood
as including also the corresponding salts, where appropriate and expedient. The same
applies in the case of tautomers of compounds of formula I and the salts thereof. The free

The compounds of formulae I, II, III, IV, VII, VIII and IX may be in the form of one of the
possible isomers or in the form of a mixture thereof, for example depending on the number
of asymmetric carbon atoms and the absolute and relative configuration thereof they may
be in the form of pure isomers, such as antipodes and/or diastereoisomers, or in the form of
mixtures of isomers, such as mixtures of enantiomers, for example racemates, mixtures of
diastereoisomers or mixtures of racemates; the invention relates both to the pure isomers
and to all possible mixtures of isomers and this is to be understood hereinbefore and
hereinafter, even if stereochemical details are not specifically mentioned in each case.
Mixtures of diastereoisomers and mixtures of racemates of compounds of formulae I, II, III,
IV, VII, VIII and IX that are obtainable in accordance with the process depending upon the
starting materials and procedures chosen, or by other means, can be separated on the
basis of the physicochemical differences between the constituents into the pure
diastereoisomers or racemates in known manner, for example by fractional crystallisation,
distillation and/or chromatography.
Correspondingly obtainable mixtures of enantiomers, such as racemates, can be separated
into the optical antipodes by known methods, for example by recrystallisation from an
optically active solvent, by chromatography on chiral adsorbents, for example high-pressure
liquid chromatography (HPLC) on acetyl cellulose, with the aid of suitable microorganisms,
by cleavage with specific immobilised enzymes, via the formation of inclusion compounds,
for example using chiral crown ethers, in which case only one enantiomer is complexed.
Apart from by the separation of corresponding mixtures of isomers, it is possible according
to the invention to obtain pure diastereoisomers or enantiomers also by generally known
methods of diastereoselective or enantioselective synthesis, for example by carrying out the
process according to the invention with starting materials having a correspondingly suitable
stereochemistry.
Advantageously, the biologically more active isomer, for example enantiomer, or mixture of
isomers, for example mixture of enantiomers, will be isolated or synthesised, insofar as the
individual components have differing biological activity.
The compounds of formulae I, II, III, IV, VII, VIII and IX also be obtained in the form of their
hydrates and/or may include other solvents, for example solvents used, where appropriate,
for the crystallisation of compounds in solid form.
The invention relates to all those forms of the process according to which a compound
obtainable as starting material or intermediate at any stage of the process is used as
starting material and all or some of the remaining steps are carried out, or a starting material
is used in the form of a derivative or a salt and/or its racemates or antipodes or, especially,
is formed under the reaction conditions.
In the process of the present invention there are preferably used those starting materials
and intermediates which result in the compounds of formula I described at the beginning as
being especially valuable.
The invention relates especially to the preparation processes described in Examples P1,
P3, P5, P7 and P8.
The invention relates also to those starting materials and intermediates used according to
the invention for the preparation of the compounds of formula I, especially those
compounds of formulae II, III, IV, VII, VIII and IX, that are novel, to the use thereof and to
processes for the preparation thereof. In particular, the compounds of formulae II, III, IV and
IX can be prepared analogously to Examples P1, P3 and P7 and P8, respectively.
It has now been found that the compounds of formula I have a microbicidal spectrum that is
especially advantageous for practical requirements in the control of phytopathogenic
microorganisms, especially fungi. They have very advantageous curative, preventive and, in
particular, systemic properties, and can be used in the protection of numerous cultivated
plants. With the compounds of formula I it is possible to inhibit or destroy the pests which
occur on plants or on parts of plants (the fruit, blossom, leaves, stems, tubers, roots) in
different crops of useful plants, while at the same time parts of plants which grow later are
also protected from phytopathogenic microorganisms.
The compounds of formula I can also be used as dressing agents for protecting seed (fruit,
tubers, grains) and plant cuttings against fungal infection as well as against
phytopathogenic fungi which occur in the soil.
Compounds of formula I are effective, for example, against the phytopathogenic fungi
belonging to the following classes: Fungi imperfect! (especially Botrytis, also Pyricularia,
Helminthosporium, Fusarium, Septoria, Cercospora, Cercosporella and Altemaria);
Basidiomycetes (e.g. Rhizoctonia, Hemileia, Puccinia). They are also effective against the
class of the Ascomycetes (e.g. Venturia and Erysiphe, Podosphaera, Monilinia, Uncinula),
but especially against the class of the Oomycetes (e.g. Phytophthora, Peronospora,
Bremia, Pythium, Plasmopara).
The compounds of formula I according to the invention are also valuable active ingredients
in the field of animal pest control, while being well tolerated by warm-blooded animals, fish
and plants. In particular, the compounds according to the invention are effective against
insects and representatives of the order Acarina, such as those occurring on useful plants
and ornamentals in agriculture and horticulture, especially in plantations of cotton,
vegetables and fruit, and in forestry. The compounds of the invention are suitable especially
for controlling insects and representatives of the order Acarina in crops of fruit and
vegetables, especially for controlling plant-destructive insects, such as Spodoptera littoralis,
Heliothis virescens, Diabrotica balteata and Crocidolomia binotalis. Further areas of use of
the compounds of the invention are in the protection of stocks and materials and in the
hygiene sector, especially in the protection of domestic animals and productive livestock.
The compounds according to the invention are effective against all or individual
development stages of normally sensitive pests, but also of resistant pests. The action of
the compounds of the invention may manifest itself, for example, in the mortality of the
pests, which occurs immediately or only after some time, for example during moulting, or in
reduced oviposition and/or hatching rate.

The good pesticidal activity of the compounds according to the invention corresponds to a
mortality of at least 50-60 % of the mentioned pests.
The activity of the compounds of the invention and of the compositions comprising them
can be substantially broadened and adapted to prevailing circumstances by the addition of
other insecticides and/or acaricides. Examples of suitable additional active ingredients
include representatives of the following classes of compounds: organophosphorus
compounds, nitrophenols and derivatives, formamidines, ureas, carbamates, pyrethroids,
chlorinated hydrocarbons, and Bacillus thuringiensis preparations.
The compounds according to the invention are used in unmodified form or preferably
together with the adjuvants conventionally employed in formulation technology, and are
therefore formulated in known manner, e.g. into emulsifiable concentrates, directly sprayable
or dilatable solutions, dilute emulsions, wettable powders, soluble powders, dusts or
granules, or by encapsulation in e.g. polymer substances. As with the nature of the
compositions, the methods of application, such as spraying, atomising, dusting, scattering
or pouring, are chosen in accordance with the intended objectives and the prevailing
circumstances.
The formulations, i.e. the compositions, preparations or mixtures comprising the compound
(active ingredient) and, where appropriate, solid or liquid adjuvants, are prepared in known
manner, for example by intimately mixing and/or grinding the active ingredient with the
adjuvants, such as extenders, e.g. solvents or solid carriers, or surface active compounds
(surfactants).
Suitable solvents are, for example: aromatic hydrocarbons, preferably the fractions of
alkylbenzenes containing 8 to 12 carbon atoms, such as xylene mixtures, alkylated
naphthalenes, aliphatic or cycloaliphatic hydrocarbons, such as cyclohexane, paraffins or
tetrahydronaphthalene, alcohols, such as ethanol, propanol or butanol, glycols and their
ethers and esters, such as propylene glycol, dipropylene glycol ether, ethylene glycol or
ethylene glycol monomethyl or monoethyl ether, ketones, such as cyclohexanone,
isophorone or diacetone alcohol, strongly polar solvents, such as N-methyl-2-pyrrolidone,
dimethyl sulfoxide or N,N-dimethylformamide, water and vegetable oils or epoxidised
vegetable oils, such as rape oil, castor oil, coconut oil or soybean oil or epoxidised rape oil,
castor oil, coconut oil or soybean oil, and, where appropriate, silicone oils.
The solid carriers used, e.g. for dusts and dispersible powders, are normally natural mineral
fillers such as calcite, talcum, kaolin, montmorillonite or attapulgite. In order to improve the
physical properties it is also possible to add highly dispersed silicic acids or highly dispersed
absorbent polymers. Suitable granulated adsorptive carriers are porous types, such as
pumice, broken brick, sepiolite or bentonite; and suitable nonsorbent carriers are calcite or
sand. In addition, a great number of granulated materials of inorganic or organic nature can
be used, especially dolomite or pulverised plant residues.
Depending on the nature of the compound to be formulated, suitable surface-active
compounds are non-ionic, cationic and/or anionic surfactants having good emulsifying,
dispersing and wetting properties. The term "surfactants" will also be understood as
comprising mixtures of surfactants.
Non-ionic surfactants are preferably polyglycol ether derivatives of aliphatic or cycloaliphatic
alcohols, saturated or unsaturated fatty acids and alkylphenols, said derivatives containing
3 to 30 glycol ether groups and 8 to 20 carbon atoms in the (aliphatic) hydrocarbon moiety
and 6 to 18 carbon atoms in the alkyl moiety of the alkylphenols. Further suitable non-ionic
surfactants are water-soluble adducts of polyethylene oxide with polypropylene glycol,
ethylenediaminopolypropylene glycol and alkylpolypropylene glycol containing 1 to 10
carbon atoms in the alkyl chain, which adducts contain 20 to 250 ethylene glycol ether
groups and 10 to 100 propylene glycol ether groups. These compounds usually contain 1 to
5 ethylene glycol units per propylene glycol unit. Representative examples of non-ionic
surfactants are nonylphenol polyethoxyethanols, castor oil polyglycol ethers,
polypropylene/polyethylene oxide adducts, tributylphenoxypolyethoxyethanol, polyethylene
glycol and octylphenoxypolyethoxyethanol. Fatty acid esters of polyoxyethylene sorbitan,
e.g. polyoxyethylene sorbitan trioleate, are also suitable non-ionic surfactants.
Cationic surfactants are preferably quaternary ammonium salts which contain, as Nsubstituent,
at least one Cs-C22a|ky| radical and, as further substituents, unsubstituted or
halogenated lower alkyl, benzyl or hydroxy-lower alkyl radicals. The salts are preferably in
the form of halides, methyl sulfates or ethyl sulfates. Examples are stearyltrimethylammonium
chloride and benzyl-di(2-chloroethyl)ethylammonium bromide.
-35-
Both water-soluble soaps and water-soluble synthetic surface-active compounds are
suitable anionic surfactants. Suitable soaps are the alkali metal salts, alkaline earth metal
salts and unsubstituted or substituted ammonium salts of higher fatty acids (C-| rj-C22)> e.g.
the sodium or potassium salts of oleic or stearic acid or of natural fatty acid mixtures which
can be obtained e.g. from coconut oil or tall oil; mention may also be made of fatty acid
methyltaurine salts. More frequently, however, synthetic surfactants are used, especially
fatty sulfonates, fatty sulfates, sulfonated benzimidazole derivatives or alkylarylsulfonates.
The fatty sulfonates or sulfates are usually in the form of alkali metal salts, alkaline earth
metal salts or unsubstituted or substituted ammonium salts and generally contain a Cg-C22-
alkyl radical, which also includes the alkyl moiety of acyl radicals; there may be mentioned
by way of example the sodium or calcium salt of lignosulfonic acid, of dodecyl sulfate or of a
mixture of fatty alcohol sulfates obtained from natural fatty acids. These compounds also
include the salts of sulfated and sulfonated fatty alcohol/ethylene oxide adducts. The
sulfonated benzimidazole derivatives preferably contain 2 sulfonic acid groups and one fatty
acid radical containing approximately 8 to 22 carbon atoms. Examples of alkylarylsulfonates
are the sodium, calcium or triethanolammonium salts of dodecylbenzenesulfonic acid,
dibutylnaphthalenesulfonic acid or of a condensate of naphthalenesulfonic acid and
formaldehyde. Also suitable are corresponding phosphates, e.g. salts of the phosphoric
acid ester of an adduct of p-nonylphenol with 4 to 14 mol of ethylene oxide, or
phospholipids.
The surfactants listed above are to be regarded merely as examples; many other
surfactants used in formulation technology that are suitable in accordance with the invention
are described in the relevant literature.
The pesticidal compositions usually comprise 0.1 to 99%, preferably 0.1 to 95%, of active
ingredient, and 1 to 99.9%, preferably 5 to 99.9%, of a solid or liquid adjuvant, it generally
being possible for 0 to 25%, preferably 0.1 to 20%, of the composition to be surfactants (in
each case percentages are by weight). Whereas commercial products will preferably be
formulated as concentrates, the end user will normally employ dilute formulations which
have considerably lower active ingredient concentrations. Typical rates of concentration are
from 0.1 to 1000 ppm, preferably from 0.1 to 500 ppm, active ingredient. The rates of
application per hectare are generally from 1 to 1000 g of active ingredient per hectare,
preferably from 25 to 500 g/ha.
Preferred formulations have especially the following composition (throughout, percentages
are by weight):
Emulsifiable concentrates:

liquid carrier:
1 to 90 %, preferably 5 to 20 %

Granules:
active ingredient:
solid carrier:
0.5 to 30 %, preferably 3 to 15 %
99.5 to 70 %, preferably 97 to 85 %
The compositions may also comprise further adjuvants, such as stabilisers, for example
vegetable oils or epoxidised vegetable oils (e.g. epoxidised coconut oil, rape oil or soybean
oil), antifoams, for example silicone oil, preservatives, viscosity regulators, binders and/or
tackifiers, as well as fertilisers or other active ingredients for obtaining special effects.

Preparation Examples
Example P1/1: 1 -[4-(2,2-Dichlorocyclopropylmethoxy)-2,5-difluorophenyl]-propan-1 -one 2-
oxime (Compound No. 1.77 in Table 1)
a) Propionic acid (2,5-difluorophenyl) ester
At 0°C-5°C, a solution of 100 g of 2,5-difluorophenol in 66.5 g of pyridine is added dropwise
in the course of 2 hours to a solution of 71.2 g of propionic acid chloride in 800 ml of
toluene and stirring is then carried out at room temperature for a further hour. The reaction
mixture is then diluted with ethyl acetate, washed twice with water and once with saturated
sodium chloride solution and the organic phase is separated off, dried with sodium sulfate
and concentrated by evaporation in vacua. The crude product is processed further without
further purification.
b) 1 -(2,5-Difluoro-4-hydroxyphenyl)-propan-1 -one
117.9 g of propionic acid (2,5-difluorophenyl) ester are heated to 60°C and then 169.1 g of
aluminium trichloride are added in small portions. When the addition is complete, the
reaction mixture is heated at 120°C until the evolution of hydrogen chloride gas can no
longer be observed. The mixture is then cooled to 50°C and 400 ml of water are added
dropwise, followed by approximately 100 ml of ethyl acetate. Extraction of the reaction
mixture is carried out several times with ethyl acetate and the combined extracts are
washed twice with water and once with saturated sodium chloride solution, dried with
sodium sulfate and concentrated by evaporation in vacua. Recrystallisation of the residue
from ethyl acetate/hexane yields 1-(2,5-difluoro-4-hydroxyphenyl)-propan-1-one having a
melting point of 116-117°C.
c) 1 -[4-(2,2-Dichlorocyclopropylmethoxy)-2,5-difluorophenyl]-propan-1 -one
40.3 g of 2-bromomethyl-1,1-dichlorocyclopropane are added dropwise at room
temperature to a suspension of 29 g of 1-(2,5-difluoro-4-hydroxyphenyl)-propan-1-one, 28.6
g of potassium carbonate and 0.5 g of potassium iodide in 95 ml of N,N-dimethylformamide.
The reaction mixture is then stirred at 90°C for 1.5 hours, cooled and poured into ice-water.
The product which precipitates is filtered off and dissolved in ethyl acetate and the solution
is washed twice with water and once with saturated sodium chloride solution, dried with
sodium sulfate and concentrated by evaporation in vacua. The crude product is made into
a slurry in cold hexane, filtered and dried in vacua, yielding 1-[4-(2,2-
dichlorocyclopropylmethoxy)-2,5-difluorophenyl]-propan-1-one having a melting point of 89-
91 °C.
d) 1 -[4-(2,2-Dichlorocyclopropylmethoxy)-2,5-difluorophenyl]-propan-1 -one 2-oxime
Hydrogen chloride gas is introduced into 350 ml of dioxane for 2 minutes and then 43.5 g of
(2,2-dichlorocyclopropylmethoxy)-2,5-difluorophenyl]-propan-1-one, followed, dropwise, by
19.8 g of isopentyl nitrite, are added. The reaction mixture is stirred at room temperature for
24 hours and then hydrogen chloride gas is again introduced for 2 minutes and the reaction
mixture is stirred for a further 30 hours at room temperature. The mixture is then rendered
basic with triethylamine and concentrated by evaporation in vacua. The residue is dissolved
in ethyl acetate and the solution is washed twice with water and once with saturated sodium
chloride solution, dried with sodium sulfate and concentrated by evaporation in vacua.
Purification by flash chromatography (silica gel, ethyl acetate/hexane 1:3) yields the title
compound having a melting point of 74-76°C.
Example P1/2:1-[4-(4-Chlorophenoxy)-2-fluorophenyl]-propan-1-one 2-oxime (Compound
No. 1.57)
a) At room temperature, 12.9 g (0.1 mol) of 4-chlorophenol are stirred vigorously for 1 hour
with 20.7 g (0.15 mol) of potassium carbonate in 150 ml of N,N-dimethylacetamide. 17.0 g
(0.1 mol) of 2,4-difluorophenyl-propane-1-one are added and the reaction mixture is stirred
for 2-3 hours at a bath temperature of 130-140°C. The reaction mixture is cooled to 25°C
and the solvent is distilled off under a high vacuum. The residue is taken up in ether and
washed with water, 10 % KOH solution and brine. The organic phase is dried over sodium
sulfate and concentrated by evaporation in vacua. An oil is obtained which, according to the
NMR-Spectrum, consists of 34 % 1-[4-(4-chlorophenoxy)-2-fluorophenyl]-propan-1-one.
b) 23.0 g of a mixture comprising approximately 34 % 1-[4-(4-chlorophenoxy)-2-fluorophenyl]-
propan-1 -one are dissolved in 250 ml of ether. At a temperature of 20-30°C, dry
hydrogen chloride is introduced for 15 minutes. Then 11.5 g (99 mmol) of isopentyl nitrite
are added dropwise in such a manner that the temperature does not exceed 25°C. The
reaction mixture is then stirred at room temperature for 18 hours. The mixture is discharged
into 500 ml of ice-water and the organic phase is separated off. The ether phase is washed
neutral with water and dried with brine and sodium sulfate. Concentration by evaporation in
vacua yields a crude product which is chromatographed on silica gel with ethyl acetate
admixed with 3-8 % hexane, under a pressure of 1.2 bar, yielding an oil which consists of
the title compound and the starting material, 1-[4-(4-chlorophenoxy)-2-fluorophenyl]-propan-
1-one.

a) A mixture of 57 g of 2-tolylglyoxylic acid methyl ester oxime and 80 g of powdered
potassium carbonate is mixed into 550 ml of dimethyl sulfoxide for 30 minutes at room
temperature and then a solution of 40 g of bromofluoromethane in 30 ml of dimethyl
sulfoxide is added dropwise at room temperature. The reaction mixture is stirred for a
further 20 hours and then poured into 1200 ml of water, neutralised with 230 ml of
-86-
hydrochloric acid and extracted four times with 250 ml of ethyl acetate each time. The
combined organic phases are washed with 200 ml of saturated sodium chloride solution,
dried with sodium sulfate and concentrated by evaporation in vacua. Purification by flash
chromatography (silica gel, ethyl acetate/hexane 1:9) yields 2-tolylglyoxylic acid methyl
ester O-fluoromethyloxime in the form of a viscous oil.
b) 56 g of 2-tolylglyoxylic acid methyl ester O-fluoromethyloxime and 0.4 g of dibenzoyl
peroxide are dissolved in 350 ml of carbon tetrachloride and heated to boiling. Then, with
irradiation with a lamp, 44.5 g of N-bromosuccinimide are added in small portions, stirring is
continued for 2 hours and, after cooling, the succinimide that has precipitated is filtered off.
The solution is then concentrated by evaporation. Purification by flash chromatography
(sililca gel, ethyl acetate/hexane 1:1) of the residue yields the title compound in the form of
a viscous oil.

Biological Examples
A) Microbicidal action
Example B1: Action against Phytoohthora infestans on tomatoes
a) Curative action
After a cultivation period of 3 weeks, tomato plants of the "Red Gnome" variety are sprayed
with a zoospore suspension of the fungus and incubated in a cabinet at 18 to 20° and 100
% humidity. Humidification is stopped after 24 hours. When the plants have dried, they are
sprayed with a mixture comprising the test compound formulated as a wettable powder in a
concentration of 200 ppm. After the spray coating has dried, the plants are again placed in
the humidity cabinet for 4 days. The activity of the test compounds is evaluated on the basis
of the number and size of the typical leaf specks that have occurred after that time.
b) Preventive-systemic action
The test compound formulated as a wettable powder is applied in a concentration of 60
ppm (based on the volume of the soil) to the soil surface of three-week-old tomato plants of
the "Red Gnome" variety planted in pots. After a 3-day waiting period, the undersides of the
leaves of the plants are sprayed with a zoospore suspension of Phytophthora infestans.
The plants are then kept in a spray cabinet for 5 days at 18 to 20°C and 100 % humidity.
After that time, typical leaf specks form, the number and size of which are used to evaluate
the activity of the test compounds.
While infestation is 100% on untreated and infected control plants, the compounds of
formula I according to one of Tables 3 to 14 reduce infestation to 20% or less in both tests.
Compounds 3.1, 3.2 and 3.15 are almost completely effective.
Example B2: Action against Plasmopara viticola (Bert, et Curt.) (Berl. et DeToni) on vines
a) Residual-preventive action
Vine seedlings of the "Chasselas" variety are grown in a greenhouse. 3 plants are sprayed
at the 10-leaf stage with a mixture (200 ppm active ingredient). After the spray coating has
dried, the undersides of the leaves of the plants are infected uniformly with a spore suspension
of the fungus. The plants are then kept in a humidity chamber for 8 days. After that
time, the control plants exhibit marked symptoms of disease. The activity of the test
compounds is evaluated on the basis of the number and size of the sites of infection on the
treated plants.
b) Curative action
Vine seedlings of the "Chasselas" variety are grown in a greenhouse and the undersides of
the leaves are infected at the 10-leaf stage with a spore suspension of Plasmopara viticola.
After 24 hours in a humidity cabinet, the plants are sprayed with a mixture of the test
compound (200 ppm active ingredient). Then the plants are kept in the humidity cabinet for
a further 7 days. After that time, the control plants exhibit symptoms of disease. The activity
of the test compounds is evaluated on the basis of the number and size of the sites of
infection on the treated plants.
In comparison with the control plants, infestation is 20% or less on the plants treated with
compounds of formula I.
Example B3: Action against Pythium debaryanum on sugar beet (Beta vulgaris)
a) Action following soil application
The fungus is cultivated on sterile oat grains and added to a soil/sand mixture. The soil so
infected is introduced into plant pots and sown with sugar beet seeds. Immediately after
sowing, a wettable powder formulation of the test compounds is poured in the form of an
aqueous suspension over the soil (20 ppm active ingredient, based on the volume of the
soil). The pots are then placed in a greenhouse at 20-24°C for 2-3 weeks. The soil is kept
uniformly moist by light spraying with water. The test is evaluated by determining the
emergence of the sugar beet plants and the number of healthy and diseased plants.
b) Action following application by dressing
The fungus is cultivated on sterile oat grains and added to a soil/sand mixture. The soil so
infected is introduced into plant pots and sown with sugar beet seeds which have been
dressed with the test compounds formulated as dressing powders (1000 ppm active
ingredient, based on the weight of the seeds). The pots containing the seeds are then
placed in a greenhouse at 20-24°C for 2-3 weeks. The soil is kept uniformly moist by light
spraying with water.
The test is evaluated by determining the emergence of the sugar beet plants and the
number of healthy and diseased plants.
Following treatment with compounds of formula I, over 80% of the plants emerge and have
a healthy appearance. In the control pots, only the occasional emerged plant, with a
diseased appearance, is observed.

(0.02% active ingredient) and are infected 48 hours later with a conidia suspension of the
fungus. The plants are incubated for 72 hours at 21 °C and high humidity and are then
placed in a greenhouse until the typical leaf specks occur. The activity of the test compound
is evaluated 12 days after infection and is based on the number and size of the leaf specks.

at 20°C), the plants are placed in a greenhouse at 22°C. Evaluation of rust pustule development
is made 12 days after infection.
b) Systemic action
5 days after sowing, wheat plants are watered with an aqueous spray mixture (0.006%
active ingredient, based on the volume of the soil). Care is taken that the spray mixture
does not come into contact with the parts of the plants above the soil. After 48 hours the
plants are infected with a uredospore suspension of the fungus. After an incubation period
of 48 hours (conditions: 95 to 100% relative humidity at 20°C), the plants are placed in a
greenhouse at 22°C. Evaluation of rust pustule development is made 12 days after
infection.

spray mixture (0.02% active ingredient) and are infected 48 hours later with a conidia
suspension of the fungus. Evaluation of fungus infestation is made 5 days after infection,
during which period 95 to 100% relative humidity and a temperature of 22°C are
maintained.
b) Systemic action
2-week-old rice plants are watered with an aqueous spray mixture (0.006% active
ingredient, based on the volume of the soil). Care is taken that the spray mixture does not
come into contact with the parts of the plants above the soil. The pots are then filled with
water so that the lowermost parts of the stems of the rice plants stand in water. After 96
hours, the plants are infected with a conidia suspension of the fungus and are kept for 5
days at 95 to 100% relative humidity and a temperature of 24°C.
Compounds of formula I largely prevent the disease from breaking out on the infected
plants. In particular, compounds 3.1, 3.2, 3.15, 4.15 and 4.27 effect a reduction in fungus
infestation of more than 90 %.

mixture (0.02% active ingredient) and are infected 24 hours later with a conidia suspension
of the fungus. The plants are incubated for 5 days at 90 to 100% relative humidity and are
placed for a further 10 days in a greenhouse at 20 to 24°C. Scab infestation is evaluated 15
days after infection.
Compounds of formula I of one of Tables 3 to 14 mainly have a lasting effect against scab
diseases. In particular, compounds 3.1, 3.2, 3.15 and 4.15 effect a reduction in fungus

after infection.
b) Systemic action
Barley plants about 8 cm in height are watered with an aqueous spray mixture (0.002%
active ingredient, based on the volume of the soil). Care is taken that the spray mixture
does not come into contact with the parts of the plants above the soil. The plants are dusted
48 hours later with conidia of the fungus. The infected plants are placed in a greenhouse at
22°C. Evaluation of fungus infestation is made 10 days after infection.
Compounds of formula I are generally able to reduce disease infestation to less than 20%,
and in some cases even completely. Compounds 3.1, 3.2, 3.15, 4.15 and 4.27 reduce
fungus infestation to less than 5 %.
Example B9: Action against Podosphaera leucotricha on apple shoots
Residual-protective action

Artificially damaged apples are treated by dropping a spray mixture (0.02% active
ingredient) onto the damaged sites. The treated fruits are then inoculated with a spore
suspension of the fungus and are incubated for one week at high humidity and about 20°C.
The fungicidal activity of the test compound is derived from the number of rotted damaged
sites.
The compounds of formula I of Tables 3 to 14 are able to prevent the rot from spreading, in
some cases completely. In particular, compounds 3.1, 3.2, 3.15 and 4.15 reduce fungus
infestation to less than 5 %.
Example B11: Action against Helminthosporium gramineum
Wheat grains are contaminated with a spore suspension of the fungus and are left to dry.
The contaminated grains are dressed with a suspension of the test compound (600 ppm
active ingredient, based on the weight of the seeds). 2 days later, the grains are placed on
suitable agar dishes and, after a further four days, the development of the fungus colonies
around the grains is assessed. The evaluation of the test compound is based on the
number and size of the fungus colonies.
Some of the compounds of formula I exhibit good activity, i.e. inhibition of the fungus
colonies. In particular, compounds 3.1, 3.2, 3.15, 4.15 and 4.27 reduce fungus infestation to
less than 5 %.

(concentration 0.002%). 2 days later, the plants are infected with a spore suspension
(1.5x105 spores/ml) of the fungus and are incubated for 36 hours at 23°C and high
humidity. Incubation is then continued at normal humidity and about 22-23°C. The fungus
infestation that has occurred is evaluated 8 days after infection. Fungus infestation is 100%
on untreated and infected control plants.
The compounds of formula I inhibit infestation with the disease in some cases almost
completely. In particular, compounds 3.1, 3.2, 3.3, 3.4, 3.15, 3.36, 4.27 and 5.103 reduce
fungus infestation to less than 5 %.
Example B13: Action against Fusarium nivale on rye
Rye of the Tetrahell variety which is naturally infected with Fusarium nivale is dressed in a
roller mixer with the test fungicide, the following concentrations being used: 20 or 6 ppm a.i.
(based on the weight of the seed).
The infected and treated rye is sown in October in the open with a seeder in plots 3 metres
long and in 6 rows. Three replicates are carried out with each concentration.
Until evaluation of the infestation is made, the test crop is cultivated under normal field
conditions (preferably in a region with unbroken snow cover during the winter months).
In order to evaluate the phytotoxicity, the emergence is assessed in the autumn and the
crop density/number of plants per unit area is assessed in the spring.
To determine the effectiveness of the test compounds, the percentage of plants attacked by
Fusarium is calculated in the spring immediately after the snow has melted. The number of
infested plants is less than 5% in the present case. The plants that have emerged have a
healthy appearance,
