DICHLOROPYRIDYL- AND DICHLOROISOTHIAZOLYL-THIOCARBOXAMIDES AND THEIR USE AS MICROBICIDES
The present invention relates to novel thiocarboxamides, to a process for their preparation and to their use as microbicides.
It has already been known that certain isothiazolecarboxamides can be employed for the control of fungi (see JP-A 149 572-1990, JP-A 59 024-1993, JP-A 9313-1994 and WO 99-24 413). Further, it has also been described that various 4-pyridinecarb- oxylic acid amides are suitable for combating fungi and for causing resistance in plants against plant pathogens (see JP-A 130 583-1988, JP-A 501 325-1995, JP-A
283 284-1989, JP-A 208 615-1996, JP-A 165 374-1997 and JP-A 249 648-1997). The fungicidal activity of such known compounds, however, it is not always satisfactory.
There have now been found novel thiocarboxamides of the formula
S Z-C NH R W in which Z represents a group of the formula
R represents C g alkyl, Cj_
4 haloalkyl, C^ alkoxy-Cι.3 alkyl, C

R2 represents hydrogen, halogen, Cj_4 alkyl or C^alkoxy and
R3 represents hydrogen, halogen, C1.4 alkyl or Cj_4 alkoxy.
Further, it has been found that thiocarboxamides of the formula (I) can be prepared by
a) reacting carboxamides of the formula
O
II z— c- -NH- (II)
in which
R and Z have the above-mentioned meanings,
with phosphorous pentasulfide in the presence of an inert diluent.
Finally, it has been found that the thiocarboxamides of the formula (I) are outstandingly active as microbicides in agriculture and horticulture, particularly as fungicides for the direct control of plant diseases or for causing resistance in plants against plant pathogens.
Surprisingly, the thiocarboxamides of the formula (I) according to the invention have a much better microbicidal activity than the already known compounds, which are structurally most similar and have the same type of action.

The compounds according to the present invention exhibit a strong microbicidal activity. Thus, they can be used for combating undesired microorganisms, such as phytopathogenic fungi and bacteriae, in agriculture and horticulture. The compounds are suitable for the direct control of undesired microorganisms as well as for generating resistance in plants against attack by undesired plant pathogens.
Resistance-inducing substances in the present context are to be understood as those substances which are capable of stimulating the defense system of plants such that the treated plants, when subsequently inoculated with undesirable microorganisms, display substantial resistance to these microorganisms.
Undesirable microorganisms in the present case are to be understood as phytopathogenic fungi and bacteriae. The substances according to the invention can thus be employed to generate resistance in plants against attack by the harmful organisms mentioned within a certain period of time after the treatment. The period of time within which resistance is brought about in general extends from 1 to 10 days, prefer- ably 1 to 7 days, after treatment of the plants with the active compounds.
Generally, the compounds according to the invention can be used as fungicides for combating phytopathogenic fungi, such as Plasmodiophoromycetes, Oomycetes,
Chytridiomycetes, Zygomycetes, Ascomycetes, Basidiomycetes and Deutero- mycetes, and can also be used as bactericides for combating bacteriae, such as
Pseudomonadaceae, R izobiaceae, Enterobacteriaceae, Corynebacteriaceae and Streptomycetaceae.
The compounds according to the present invention are particularly suitable for causing resistance against infection of plants by plant pathogens, such as Pyricularia oryzae, Phythophthora infestans etc.
The good toleration, by plants, of the active compounds, at the concentrations required for combating plants diseases, permits treatment of above-ground parts of plants, of vegetative propagation stock and seeds, and of the soil.
The compounds according to the present invention have a low toxicity against warmblooded animals and therefore can be used safely.
The active compounds can be converted into the customary formulations, such as solutions, emulsions, wettable powders, suspensions, powders, foams, pastes, granules, tablets, aerosols, natural and synthetic materials impregnated with active compound, very fine capsules in polymeric substances, coating compositions for use on seed, and formulations used with burning equipment, such as fumigating cartridges, fumigating cans and fumigating coils, as well as ULV cold mist and warm mist formulations.
These formulations may be produced in known manner, for example by mixing the active compounds with extenders, that is to say liquid or liquefied gaseous or solid diluents or carriers, optionally with the use of surface-active agents, that is to say emulsifying agents and/or dispersing agents and/or foam-forming agents. In the case of the use of water as an extender, organic solvents can, for example, also be used as auxiliary solvents.
As liquid solvents diluents or carriers, there are suitable in the main, aromatic hydrocarbons such as xylene, toluene or alkyl naphthalenes, chlorinated aromatic or
chlorinated aliphatic hydrocarbons, such as chlorobenzenes, chloroethylenes or methylene chloride, aliphatic hydrocarbons, such as cyclohexane or paraffins, for example mineral oil fractions, alcohols, such as butanol or glycol as well as their ethers and esters, ketones, such as acetone, methyl ethyl ketone, methyl-isobutyl ketone or cyclohexanone, or strongly polar solvents, such as dimethylformamide and dimethyl-sulphoxide, as well as water.
By liquefied gaseous diluents or carriers are meant liquids which would be gaseous at normal temperature and under normal pressure, for example aerosol propellants, such as halogenated hydrocarbons as well as butane, propane, nitrogen and carbon dioxide.
As solid carriers there may be used ground natural minerals, such as kaolings, clays, talc, chalk, quartz, attapulgite, montmorillonite or diatomaceous earth, and ground synthetic minerals, such as highly-dispersed silicic acid, alumina and silicates. As solid carriers for granules there may be used crushed and fractionated natural rocks such as calcite, marble, pumice, sepiolite and dolomite, as well as synthetic granules of inorganic and organic meals, and granules of organic material such as sawdust, coconut shells, maize cobs and tobacco stalks.
As emulsifying and/or foam-forming agents there may be used non-ionic and anionic emulsifiers, such as polyoxyethylene-fatty acid esters, polyoxyethylene-fatty alcohol ethers, for example alkylaryl polyglycol ethers, alkyl sulphonates, alkyl sulphates, aryl sulphonates as well as albumin hydrolysis products.
Dispersing agents include, for example, lignin sulphite waste liquors and methyl - cellulose.
Adhesives such as carboxymethylcellulose and natural and synthetic polymers in the form of powders, granules or latices, such as gum arabic, polyvinyl alcohol and poly- vinyl acetate, can be used in the formulation.
It is possible to use colorants such as inorganic pigments, for example iron oxide, titanium oxide and Prussian Blue, and organic dyestuffs, such as alizarin dyestuffs, azo dyestuffs or metal phthalocyanine dyestuffs, and trace nutrients, such as salts of iron, manganese, boron, copper, cobalt, molybdenum and zinc.
The formulations in general contain from 0.1 to 95 per cent by weight of active compound, preferably from 0.5 to 90 per cent by weight.
The active compounds according to the invention can be present in the formulations or in the various use forms as a mixture with other known active compounds, such as fungicides, bactericides, insecticides, acaricides, nematicides, herbicides, bird repellents, growth factors, plant nutrients and agents for improving soil structure.

The active compounds can be used as such or in the form of their formulations or the use forms prepared therefrom by further dilution, such as ready-to-use solutions, emulsions, suspensions, powders, tablets, pastes, microcapsules and granules. They are used in the customary manner, for example by watering, immersion, spraying, atomizing, misting, vaporizing, injecting, forming a slurry, brushing on, dusting, scattering, dry dressing, moist dressing, wet dressing, slurry dressing or encrusting.
In the treatment of parts of plants, the active compounds concentration in the use forms can be varied within a substantial range. They are, in general, from 1 to 0.0001% by weight, preferably from 0.5 and 0.001%.
For the treatment of seed, amounts of active compound of 0.001 to 50 g, especially
0.01 to 10 g, are generally employed per kilogram of seed.
For the treatment of soil, active compound concentrations, at the point of action, of 0.00001 to 0.1% by weight, especially of 0.0001 to 0.02%, are generally employed.
As already mentioned above, all plants and parts of plants can be treated according to the invention. In a preferred embodiment naturally occurring plant species and plant varieties or those obtained by conventional biological breeding methods, such as crossbreeding or protoplast fusion as well as parts of such plants are treated. In an additional preferred embodiment transgenic plants and plant varieties which have been obtained by genetic engineering methods, possibly in combination with conventional methods (genetically modified organisms) and parts of such plants are treated. The term "parts" or "parts of plants" or "plant parts" is explained above.
According to the invention plants of the plant varieties commercially available or used at any particular time are very preferably treated. Plant varieties are understood
to be plants with specific properties ("traits") which have been obtained both by conventional breeding, by mutagenesis or by recombinant DNA techniques. They can be varieties, biotypes or genotypes.
Depending on the species or varieties of plants, their location and growth conditions
(the types of soil, climate, vegetation period and feed concerned), superadditive ("synergistic") effects can occur as a result of the treatment according to the invention. Effects such as for example reduced application rates and/or broadening of the activity spectra and/or increased activity of the compounds and compositions usable according to the invention, improved plant growth, increased tolerance of high or low temperatures, increased tolerance of dry conditions or water or ground salt contents, increased flowering capacity, facilitated harvesting, acceleration of maturity, increased crop yields, higher quality and/or increased nutritional value of the harvested crops and increased storing quality and/or processibility of the harvested crops are possible, which are greater than those actually expected.
Preferred transgenic plants or plant varieties (obtained by genetic engineering) to be treated according to the invention include all plants which as a result of the genetic modification concerned have received genetic material which provides them with particularly advantageous valuable properties ("traits"). Examples of such properties are improved plant growth, increased tolerance of high or low temperatures, increased tolerance of dry conditions or water or ground salt contents, increased flowering capacity, facilitated harvesting, acceleration of maturity, increased crop yields, higher quality and/or increased nutritional value of the harvested crops and increased storing quality and/or processibility of the harvested crops. Additional and particularly noteworthy examples of such properties are increased resistance of the plants to animal and microbial pests, such as to insects, mites, phytopathogenic fungi, bacteria and/or viruses as well as increased tolerance by the plants of certain herbicidal active compounds. Examples which may be mentioned of transgenic plants are the important crop plants such as cereals (wheat and rice), com, soybeans, potatoes, cotton, rape and fruit plants (producing apples, pears, citrus fruits and
grapes), the crop plants corn, soybeans, potatoes, cotton and rape being particularly noteworthy. Particularly significant properties ("traits") are increased resistance of the plants to insects due to the toxins forming in the plants, and in particular those which are produced in the plants (hereinafter refeπed to as "Bt plants") by the genetic material obtained from Bacillus Thuringiensis (e.g. by the genes CrylA(a), CrylA(b),
CrylA(c), CryllA, CryIIIB2, Cry9c Cry2Ab, Cry3Bb and CrylF and combinations thereof). Particularly significant properties ("traits") are the increased resistance of plants to fungi, bacteria and viruses due to systemically acquired resistance (SAR), systemin, phytoalexins, elicitors and resistance genes and correspondingly expressed proteins and toxins. Particulary significant properties ("traits") are also increased tolerance by the plants of certain herbicidal active compounds, such as for example imidazolinones, sulphonylureas, glyphosate or phosphinotricine (e.g. the "PAT" gene). The corresponding genes imparting the required properties ("traits") can also occur in the transgenic plants in combination with each other. Examples which may be mentioned of "Bt plants" are varieties of corn, cotton, soybeans and potatoes which are sold under the trade names YIELD GARD® (e.g. com, cotton, soybeans), KnockOut® (e.g. corn), StarLink® (e.g. corn), Bollgard® (cotton), Nucotn® (cotton) and NewLeaf® (potatoes). Examples which may be mentioned of herbicide-tolerant plants are varieties of corn, cotton and soybeans which are sold under the trade names Roundup Ready® (tolerance of glyphosate, e.g. com, cotton, soybeans),
Liberty Link® (tolerance of phosphinotricine, e.g. rape), IMI® (tolerance of imidazolinones) and STS® (tolerance of sulphonylureas, e.g. corn). Herbicide- resistant plants (bred for herbicide tolerance in the conventional manner) which may be mentioned are also the varieties (e.g. com) sold under the name Clearfield®. The above statements do of course also apply to any plant varieties which may be developed in the future or launched onto the market in the future and which have the genetic properties ("traits") described above or developed in the future.
According to the invention the above-mentioned plants can be particularly advantageously treated with the compounds of the general formula I or the active compound mixtures according to the invention. The preferred ranges mentioned
above for the active compounds or mixtures also apply to the treatment of these plants. Particularly advantageous is the treatment of plants with the compounds or mixtures specifically listed in the present text.
Then the present invention will be described more specifically by the following examples. However, the present invention should not be restricted to them in any way.
Examples
Synthesis Example 1
A suspension of 0.8 g (2.71 mmol) of N-(α-methylbenzyl)-2,6-dichloroisonicotinic acid amide and 0.6 g (2.71 mmol) of phosphorous pentasulfide in 30 ml of toluene was refluxed for 6 hours by heating. After cooling to room temperature, the precipitate was filtered off and toluene was distilled off under reduced pressure. The residue was subjected to silica gel column chromatography to obtain 0.54 g of N-(α- methylbenzyl)-2,6-dichloroisonicotinic acid thioamide. Mp: 93 to 96°C, yield: 64%.

Preparation of intermediates
Synthesis Example 2
A tetrahydrofuran solution (5 ml) of a mixture of 0.61 g (5 mmol) of α- methylbenzylamine and 1.51 g (15 mmol) of triethylamine was added dropwise to a tetrahydrofuran solution (10 ml) of 2,6-dichloroisonicotinic acid chloride under cooling with ice. After stirring for 2 hours at a room temperature, water (20 ml) and ether (40 ml) were added and the mixture was stirred. The ether layer was successively washed with a 10 % hydrochloric acid aqueous solution, water, a saturated sodium hydrogencarbonate aqueous solution and a saturated brine solution and then dried over anhydrous sodium sulfate. After distilling ether off under reduced pressure, the residue was subjected to silica gel column chromatography to obtain 1.1 1 g of N-(α-methylbenzyl)-2,6-dichloroisonicotinic acid amide. Mp: 162 to 163 °C, yield: 75 %.
Synthesis Example 3
A mixture of 10 g (49 mmol) of 4-(trifluoromethoxy)-acetophenone and 33 ml of formamide was heated to 140 to 150°C, and 6.77 g (147 mmol) of formic acid were slowly added dropwise while maintaining this temperature. After finishing the addition, the solution was heated for further 2 hours at 150°C. After cooling, water was added, and the mixture was extracted with methylene chloride. The methylene
chloride layer was washed with water and dried over anhydrous sodium sulfate. After distilling methylene chloride off under reduced pressure, 28 ml of concentrated hydrochloric acid were added to the residue, and the solution was refluxed for 2 hours by heating. After cooling, water was added, and the mixture was alkalized with sodium hydroxide and then extracted with methylene chloride. The methylene chloride layer was washed with water and dried over anhydrous potassium carbonate. Then, methylene chloride was distilled off under reduced pressure, and the residue was refined by distillation to obtain 7.2 g of 4-(trifluoromethoxy)-α-methylbenzyl- amine. Yield: 72 %.
Synthesis Example 4
An excess amount of thionyl chloride was added to 22.7 g (114.65 mmol) of 3,4- dichloro-5-carboxylic acid, and refluxed for 2 hours by heating. Excess thionyl chloride was distilled off, and then the residue was refined by distillation to obtain 16.3 g of 3,4-dichloroisothiazole-5-carboxylic acid chloride. Yield: 66 %.
Biological Test Examples
Test Example A
Seed treatment efficacy test against rice blast
Preparation of formulations of the compounds tested
Active compound: 30 - 40 parts by weight Carrier: mixture of diatomaceous earth and kaolin (1:5), 55-65 parts by weight
Emulsifier: polyoxyethylene alkyl phenyl ether, 5 parts by weight
The above-mentioned amounts of active compound, carrier and emulsifier are crushed and mixed to make a wettable powder. A portion of the wettable powder comprising the prescribed amount of active compound is diluted with water and used for testing.
Testing procedure
Seeds of paddy rice (cultivar: Kasabue) were soaked in a diluted solution of an active compound having the prescribed concentration. 5 ml of such solution, which had been prepared as mentioned above, were used per 150 grains of seed. Soaking was conducted at a temperature of 20°C for 5 days. After the soaking, the air-dried seeds were sown in 2 plastic pots, each having a diameter of 9 cm, and the seeds were germinated by placing the pots in a warmed nursery box (32°C) for 3 days. After cultivating the seedlings for 2 weeks, the plants reached the 2 - 2.5 leaf stage. A spore suspension of artificially cultured Pyricularia oryzae was then sprayed on the test plants once, and the plants were kept at a temperature of 25°C and a relative atmospheric humidity of 100% for infection. Seven days after the inoculation, the infection rate per pot was classified and evaluated and the control value (%) was calculated. Phytotoxicity was tested at the same time.
This test is an average of the results of 2 replications.
