The invention relates to new, fungicidally active pyrazole compounds of the general formula ##STR1## wherein Ar is an unsubstituted phenyl group or a phenyl group, substituted with 1 or 2 substituents selected from the group consisting of C.sub.1 -C.sub.4 alkyl, halogen, nitro, cyano and C.sub.1 -C.sub.4 alkoxy, or with 3 halogen atoms,

Fungicidally active pyrazole compounds

The invention relates to new thio compounds of the general formula ##STR1## wherein R is an alkyl group substituted or not substituted with halogen and having 1-12 carbon atoms, an alkenyl or alkynyl group having 2-4 carbon atoms, an alkadienyl group having 3 or 4 carbon atoms or a substituted or unsubstituted phenyl or phenyl(C.sub.1 -C.sub.4)alkyl group;

Thio compounds having fungicidal activity

The invention relates to new thiazole compounds of the general formula ##STR1## wherein R is an C.sub.1 -C.sub.12 alkyl group or a phenyl group, which groups are unsubstituted or substituted with halogen, nitro or cyano;

New thiazole compounds having fungicidal activity

The invention relates to new nitrothiophenes of the general formula ##STR1## wherein R is an alkyl group having 1 to 12 carbon atoms, which alkyl group may be substituted with a phenyl group substituted, if desired, with nitro, halogen, alkyl with 1 to 4 carbon atoms or alkoxy with 1 to 4 carbon atoms, with an alkoxycarbonyl group having 2 to 5 carbon atoms, or with a thiocyanato group,

Fungicidal and/or bactericidal compositions containing nitrothiophenes,

The invention relates to new nitrothiophenes of the general formula ##STR1## wherein R is an alkyl group having 1 to 12 carbon atoms, which alkyl group may be substituted with a phenyl group substituted, if desired, with nitro, halogen, alkyl with 1 to 4 carbon atoms or alkoxy with 1 to 4 carbon atoms, with an alkoxycarbonyl group having 2 to 5 carbon atoms, or with a thiocyanato group, or

Nitrothiophenes, fungicidal and/or bactericidal compositions containing

The invention relates to novel 2-aryliminohexahydropyrimidines and imidazolidines, of the formula ##STR1## as well as to salts and complexes thereof, having fungicidal activity. These compounds are particularly active against rust of beans, brown rust of wheat and mildew on cereals. After having been processed into compositions, the compounds of the invention can successfully be used to prevent or control mould infections in agriculture and horticulture in a dosage of 200-1000 g of active substance per hectare. Very active fungicides are, for example, 2-(4-cyclohexyl-phenyl) iminohexahydropyrimidine and 2-(4-n-hexyl-phenyl) iminohexahydropyrimidine, as well as the sulphuric acid salts of these compounds and complexes with zinc salts.

2-Arylamino-hexahydropyrimidines, compositions containing same, and

2-Arylimino-imidazolidines, compositions containing same, and method of

The compound of N,N',N'-trimethyl trithioisocyanurate and the novel compound N,N',N'-trimethyl 2-iminodithioisocyanurate have been found to be effective in protecting rice against Pyricylaria oryzae.

Trimerization of methyl-isothiocyanate and N,N',N'-trimethyl

Composition active against Pyricularia oryzae

The invention relates to a composition against phytophagous micro-organisms, comprising 2-cyano-5-nitro-thiazole. Infections by phytophagous micro-organisms in agriculture and horitculture can be prevented by treating the seed prior to sowing or the soil destined for sowing or planting with the composition in a dosage of from 100 to 600 mg of active substance per kg of seed and from 2 to 100 kg of active substance per hextare, respectively.
