PURPOSE:To obtain the titled composition, containing N-(2,4-difluorophenyl)-2-(3- trifluoromethylphenoxy)-nicotinamide and a specific pyrazole compound as active ingredients and capable of exhibiting effects in a small dose of chemical without giving phytotoxicity to paddy rice. CONSTITUTION:A herbicidal composition containing N-(2,4-difluorophenyl)-2-(3- trifluoromethylphenoxy)-nicotinamide and 4-(2,4-dichloro-3-methylbenzoyl)-1,3- dimethyl-5-(p-methylphenacyloxy)pyrazole at 1:10-40 weight ratio. The composition is capable of controlling a wide range of grass species in a small dose of chemical in which effects are not exhibited by independent use of each ingredient. Furthermore, controlling effects are sustained for a long period without permitting post-emergence of weeds. The effect application amount is 0.5-2.5kg/ha expressed in terms of the amount of the active ingredients. The use period is optimally 1-6 days after transplanting. |
