Abstract
Fungicidal-N-(3-halo-2,6-dinitro-4-trifluoromethylphenyl)-pyrrolidones having the formula: ##STR1## where X is a halogen, PA1 Y is oxygen or sulfur, and PA1 R is H or lower alkyl, of up to 4 carbon atoms, Are prepared by reacting a 2,4-dihalo-3,5-dinitrobenzotrifluoride with an alkali metal salt of a pyrrolidone. The compounds of the invention show good fungicidal activity, particularly against rice spot and tomato blight.
