There are described new benzoisothiazoles of general formula I ##STR1## wherein X and R have meanings given in the description, a process for their preparation and their use as pesticides, especially against nematodes.

Benzoisothiazoles, their preparation and their use as pesticides

There are described new 5-substituted 3-arylisoxazole derivatives of general formula I ##STR1## in which in which R.sub.1 and R.sub.2 have the meanings given in the description, processes for their preparation and their use as pesticides, especially against nematodes.

5-substituted 3-arylisoxazole derivatives, their preparation and their

A composition is disclosed for the control of harmful organisms, containing at least one .alpha.-alkylthiocinnamic acid nitrile of the formula ##STR1## in which R is an if necessary, one or more times, the same or differently, substituted by halogen, C.sub.1 -C.sub.4 -alkyl, C.sub.1 -C.sub.4 -alkoxy, C.sub.1 -C.sub.4 -alkylthio or trifluoromethyl, aromatic hydrocarbon and R.sub.1 is a straight-chain C.sub.1 -C.sub.4 -alkyl or cyanoethyl, as well as a process for the production of these compounds and a method for the control of said harmful organisms.

Alkylthiocinnamic acid nitriles for the control of harmful organisms

The invention concerns new xylite derivatives, methods for the production of these compounds as well as compositions containing them having growth regulatory activity for plants.

Xylite derivatives, methods for their production as well as compositions

A method for production of novel antifungal 1,3,4-thiadiazole derivatives having a composition of the general formula ##STR1## wherein R.sub.1 and R.sub.2 are independently alkyl with from 1 to 6 carbon atoms, alkenyl with from 2 to 6 carbon atoms, alkinyl with from 2 to 6 carbon atoms or cycloalkyl with from 3 to 6 carbon atoms is provided. 1,3,4-thiadiazole derivatives of a composition of the general formula ##STR2## are reacted with a compound having the composition of the general formula R.sub.1 -SH resulting in compounds of a composition having the formula ##STR3## which in turn are oxidized with an organic or inorganic oxidant.

Fungicidal 2-sulfinyl-5-sulfonyl-1,3,4-thiadiazole derivatives

1,3,4-thiadiazole-2-carboxylic acid derivatives of the formula ##STR1## wherein R is C.sub.1 -C.sub.6 -alkyl, C.sub.2 -C.sub.6 -alkenyl, C.sub.2 -C.sub.6 -alkinyl or C.sub.3 -C.sub.6 -cycloalkyl,

1,3,4-Thiadiazole-2-carboxylic acid derivatives, process for making the

1,2,3-Triazole carboxylic acid amides, of the formula ##STR1## in which R.sub.1, R.sub.2, R.sub.3, R.sub.4 and n have the meaning defined in the specification in connection with formula I. The compounds have a broad biocidal, particularly herbicidal, insecticidal, acaricidal, fungicidal and nematocidal activity. They have a high degree of selectivity towards agriculturally valuable plants.

1,2,3-Triazole carboxylic acid amides and biocidal compositions

A pesticide which contains at least one compound of the formula ##STR1## in which Hal is halogen. The compositions have both a fungicidal and nematicidal action and have a high compatibility with agriculturally and horticulturally useful plants.

5-Nitrothiazole containing pesticide composition

Salts of carbamic and thiocarbamic esters are used having fungicidal and fungistatic action, said salts having the general formula ##STR1## wherein R is an aliphatic hydrocarbon radical with preferably 2 to 4 carbon atoms, X is oxygen or sulfur, and n is an integer from 2 to 4, with an inorganic or organic acid.

Salts of thiocarbamic esters with fungicidal and fungistatic action

New 1,3,4-thiadiazoles substituted in the 2 and 5 positions for use as soil and seed fungicides, nematocides and the processes therefor.

2-Trichloromethyl-5-methylsulfinyl-1,3,4-thiadiazole

The specification discloses the preparation and use, as fungicides and nematocides, of 2,5-substituted-1,3,4-thiadiazoles having the structure: ##STR1## wherein R.sub.1 is a lower haloalkyl and R.sub.2 is an aliphatic hydrocarbon. The instant invention is directed to methods for the control of fungi and nematodes in soil and seeds and to compounds useful in such methods. In another aspect, the invention is concerned with the preparation of 2,5-substituted-1,3,4-thiadiazoles and formulation for agricultural use in which such compounds are the principal biocidal ingredient.

2,5-Substituted-1,3,4-thiadiazoles as fungicides

The specification discloses esters of benzimidazole-1-carboximidic acids having antifungal properties and the use of these compounds for the protection of crops and plants from attack by fungi.
