Ever changing problems in agricultural weed control require periodic introduction of new herbicides. Imidazo[4,5-c]pyrazoles, which were considered of interest as potential herbicides, were synthesized and examined for the pre-emergence, post-emergence, and post-transplant control of weeds in rice against broadleaf and grass weed species. The data obtained suggest that some imidazo[4,5-c]pyrazoles have potential herbicidal activity against a wide range of weeds, with 5-methyl, 5-thiomethyl, and 5-unsubstituted derivatives being the most effective. No herbicidal activity was observed in the 5-methylsulfonylimidazo[4,5-c]pyrazole and imidazo[4,5-c]pyrazolone series.

Abstract

Ever changing problems in agricultural weed control require periodic introduction of new herbicides. Imidazo[4,5-c]pyrazoles, which were considered of interest as potential herbicides, were synthesized and examined for the pre-emergence, post-emergence, and post-transplant control of weeds in rice against broadleaf and grass weed species. The data obtained suggest that some imidazo[4,5-c]pyrazoles have potential herbicidal activity against a wide range of weeds, with 5-methyl, 5-thiomethyl, and 5-unsubstituted derivatives being the most effective. No herbicidal activity was observed in the 5-methylsulfonylimidazo[4,5-c]pyrazole and imidazo[4,5-c]pyrazolone series.
