WO 98/52945 PCT/EP98/02754 PYRIDYLTHIO-DITHIAZOLE DIOXIDE DERIVATIVES AND THEIR USE AS

PESTICIDES

The invention relates to new S-pyridyl-dithiazole dioxides, to processes for their preparation, and to their use in the protection of plants and materials.

Dithiazoles with a 5-membered ring have already been described, but a biological effect is not mentioned (see K. Dickor6, Lieb. Ann. Chem. 671 (1964); US-PA 3 345 374). S-Aryldithiazole dioxides have been disclosed, but their spectrum of action does not reach the required level, especially as regards the bactericidal action (see DE 19 545 635). There have also been described dithiazine oxides (6-membered rings) which are alkyl-substituted on the S, but a biological effect is not mentioned (see Nakahashi et al., Bull. Chem. Soc. Jpn. 45, 3217 (1972); Hasegawa, K. et al., Bull.

Chem. Soc. Jpn. 45, 1567 (1972)).

11 The fact that the active compounds are well tolerated by plants also permits the treatment of plants at the concentrations required for controlling plant diseases, thereby permitting the treatment of aerial parts of plants, of propagation stock and seeds, and of the soil.

Depending on their particular physical and/or chemical properties, the active compounds of the formula can be converted to the customary formulations, such as solutions, emulsions, suspensions, powders, foams, pastes, granules, aerosols and microencapsulations in polymeric substances.

These formulations or compositions are produced in a known manner, for example by mixing the active compounds with extenders, that is, liquid solvents, liquefied gases under pressure, and/or solid carriers, optionally with the use of surfactants, that is, emulsifiers and/or dispersants, and/or foam formers. In the case of the use of water as an extender, organic solvents can, for example, also be used as auxiliary solvents.

The following are mainly suitable as liquid solvents: aromatics such as xylene, toluene or alkylnaphthalenes, chlorinated aromatics 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 and their ethers and esters, ketones such as acetone, methyl ethyl ketone, methyl isobutyl ketone or cyclohexanone, strongly polar solvents such as dimethylformamide and dimethyl sulphoxide, or else water; liquefied gaseous extenders or carriers are to be understood as meaning liquids which are gaseous at ambient temperature and under atmospheric pressure, for example aerosol propellants such as halogenohydrocarbons, or else butane, propane, nitrogen and carbon dioxide; suitable solid carriers are: for example ground natural minerals, such as kaolins, clays, talc, chalk, quartz, attapulgite, montmorillonite or diatomaceous earth, and ground synthetic minerals such as highly-disperse silica, alumina and silicates; suitable solid carriers for granules are: for example crushed and fractionated natural rocks such as calcite, marble, pumice, sepiolite and dolomite, or else synthetic granules of inorganic and organic meals, and granules of organic S material such as sawdust, coconut shells, maize cobs and tobacco stalks; suitable 12emulsifiers and/or foam formers are: for example non-ionic and anionic emulsifiers, such as polyoxyethylene fatty acid esters, polyoxyethylene fatty alcohol ethers, for example alkylaryl polyglycol ethers, alkylsulphonates, alkyl sulphates, arylsulphonates, or else protein hydrolysates; suitable dispersants are: for example lignin-sulphite waste liquors and methylcellulose.

Adhesives such as carboxymethylcellulose and natural and synthetic polymers in the form of powders, granules or latices, such as gum arabic, polyvinyl alcohol and polyvinyl acetate, or else natural phospholipids such as cephalins and lecithins and synthetic phospholipids can be used in the formulations. Other additives can be mineral and vegetable oils.

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 and metal phthalocyanine dyestuffs, and trace nutrients such as salts of iron, manganese, boron, copper, cobalt, molybdenum and zinc.

The efficacy and the spectrum of action of the active compounds of the formula or the compositions, precursors or, quite generally, formulations which can be prepared from them can be increased when, if appropriate, other antimicrobially active compounds, fungicides, bactericides, herbicides, insecticides or other active compounds for widening the spectrum of action or achieving specific effects such as, for example, an additional protection from insects, are added.

The use concentrations of the active compounds, or active compound combinations, to be used depends on the species and the abundance of the microorganisms to be controlled and on the composition of the material to be protected. The optimal rate can be determined by test series. In general, the use concentrations are in the range of 0.001 to 5% by weight, preferably 0.05 to 1.0% by weight, based on the material to be protected.

Use Example A To demonstrate the efficacy against fungi, the minimum inhibitory concentrations (MICs) of compositions according to the invention were determined: Active compounds according to the invention are added at concentrations of 0.1 mg/ 1 to 5000 mg/1 to an agar made with malt extract. After the agar has solidified, it is contaminated with pure-bred cultures of the test organisms given in Table 2. The cultures are stored for 2 weeks at 28°C and a relative atmospheric humidity of 60 to 70%, and the MIC is then determined. MIC is the lowest concentration of active compound at which no growth whatsoever by the microbial species used takes place; it is shown in Table 2 below.
