Abstract

The phytotoxicity of N,N-dimethyl-2,2-diphenylacetamide [diphenamid], N-methyl-2,2-diphenylacetamide, 2,2-diphenylacetamide, and 2,2-diphenylacetic acid was studied on tomatoes [Lycopersicon esculentum Mill.], common lambsquarters [Chenopodium album L.], redroot pigweed [Amaranthus retroflexus L.], and rape [Brassica napus L.], by means of nutrient solution culture techniques. Diphenamid was the most phytotoxic; 2,2-diphenylacetic acid was the least active. Only minor differences in the arithmetical means of the phytotoxicity indices existed in the phytotoxicity of the N-methyl and amide analogs of diphenamid.
