ABSTRACT OF THE DISCLOSURE The invention relates to new nitrothiophenes of the general formula (I) Image wherein R is C1-C12 alkyl, optionally substituted by C2-C4 alkoxy- carbonyl or by thiocyanato, or R is phenyl, pyridyl or N-oxypyridyl, which groups are optionally substituted by nitro, halo, C1-C4 alkyl, or C1-C4 alkoxy; R1 is hydrogen, halogen, C1-C4 alkyl or phenyl; R2 is hydrogen atom, C1-C4 alkyl, cyano, C1-C5 alkanoyl, C3-C10 .alpha.,.alpha.-alkylenedioxyalkyl, C2-C5 alkoxycarbonyl, C1-C4 .alpha.- hydroxyalkyl, C1-C4 .alpha. -haloalkyl, C2-C5 alkoxycarboximidoyl, or dialkylaminosulphonyl the alkyl groups of which have 1-4 carbon atoms; and n is 0, 1 or 2. The compositions are particularly suitable to prevent infections by phytophagous microorganisms in agriculture and horticulture. For this purpose the seed is treated prior to sowing or the soil destined for sowing or planting is treated with the composition in a dosage from 100 to 1,500 mg of active substance per kg of seed and from 2 to 100 kg of active substance per hectare, respectively.
