Problems solved by technology

The trade name of flufentrazone is fentrazone-ethyl, the common name in English is carfentrazone-ethyl, and the chemical name is ethyl-2-chloro-3-{2-chloro-5-[4-(difluoromethyl)-4, 5-dihydro-3-methyl-5-oxo-1H-1,2,4-triazol-1-yl]-4-fluorophenyl}propionic acid ethyl ester) is a selective contact type stem Leaf treatment agent kills plants by inhibiting photosynthesis. It is characterized by rapid herbicide, and weeds will all die within 3-4 days of using the medicine at a suitable temperature. However, it has a narrow weeding range and a short duration. High rate of grass revival
Nicosulfuron belongs to sulfonylurea herbicides, the English common name is Nicosulfuron, and the chemical name is 2-(4,6-dimethoxypyrimidin-2-ylcarbamoylaminosulfonyl)-N,N-di Methylnicotinamide is a selective systemic conduction stem leaf and soil treatment herbicide. This type of herbicide kills weeds by inhibiting acetolactate synthase. It is characterized by slow weeding effect and relatively narrow weeding range. , the weeding effect is not good at low temperature

Abstract

A composite herbicide features that its active components are nicosulfuron and profluazone in the ratio of 0.1-90: 90-0.1. Its advantages are low poison and broad spectrum.

Description

【Technical field】 [0001] The present invention relates to a herbicidal composition, which contains an active ingredient composed of nicosulfuron-methyl and flumetrazone. 【Background technique】 [0002] Due to competing with crops for glory and water and fertilizer, farmland weeds cause great losses to crop production every year. The current method of preventing and controlling farmland weeds is mainly to spray pesticides. The trade name of flufentrazone is fentrazone-ethyl, the common name in English is carfentrazone-ethyl, and the chemical name is ethyl-2-chloro-3-{2-chloro-5-[4-(difluoromethyl)-4, 5-dihydro-3-methyl-5-oxo-1H-1,2,4-triazol-1-yl]-4-fluorophenyl}propionic acid ethyl ester) is a selective contact type stem Leaf treatment agent kills plants by inhibiting photosynthesis. It is characterized by rapid herbicide, and weeds will all die within 3-4 days of using the medicine at a suitable temperature. However, it has a narrow weeding range and a short duration. Gra...
