Novel 4-thioxopyrimidine compound of formula (I), wherein A designates a fused benzene or thiophene fused in [2,3-d] position; R1 is hydrogen or halogen; R2 is hydrogen or halogen; R3 is C2-C5alkyl or cyclopropylmethyl; and R4 is C2-C5alkyl or cyclopropylmethyl, in the free form or in salt form; exhibit useful biological properties for controlling phytopathogenic microorganisms. The novel compounds may be used in the agricultural field for controlling of microbicides on crop plants, e.g. phytopathogenic fungi. |
