US 6,476,061 B1 · Fungicides containing pyrrolidones as their active agents

Abstract

The invention relates to fungicides containing compounds of formula (I) as their active agents, the radicals in said formula (I) having the following meanings: R1 is hydrogen, C1-C6-alkyl, C1-C6-alkylcarbonyl, formyl or C1-C6-halogenalkylcarbonyl; R2 is hydrogen, C1-C6-alkyl or C1-C6-halogenalkyl; R3-R12 are hydrogen, halogen, C1-C8-cycloalkyl, C1-C6-alkyl, C1-C6-halogenalkyl, C1-C6-alkoxy, C1-C6-halogenalkoxy, C1-C6-alkylsulfonyl, C1-C6-halogenalkylsulfonyl, formyl, cyano, C1-C6-alkylthio or phenyl which can optionally be substituted by halogen atoms, C1-C6-alkyl or C1-C6-halogenalkyl groups, and to their agriculturally usable salts. The invention also relates to methods for combating fungi in plants using these fungicides.
