Abstract

The invention discloses a sethoxydim compound herbicide. The sethoxydim compound herbicide is prepared from an active ingredient I, namely, sethoxydim and an active ingredient II, wherein the active ingredient II is one of or a combination of more of fomesafen, oxyfluorfen, aclonifen, bifenox, fluoroglycofen and lactofen; the mass ratio of the active ingredient I to the active ingredient II is (1:60)-(60:1), preferably, (1:30)-(30:1), more preferably, (1:10)-(10:1), and the sum of the mass of the active ingredient I, namely, sethoxydim and the active ingredient II is 5%-85% of the total mass of the sethoxydim compound herbicide. The sethoxydim compound herbicide can be used for controlling grassy weed and broadleaf weed in a soybean field, has a remarkable synergic effect, is high in herbicidal activity, can delay the resistance of weed and is very safe to soybeans and succeeding crops.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to a compound herbicide containing sethoxydim, which can be used for weeding in soybean fields. Background technique [0002] Soybean is an important food crop and oil crop in my country, an important non-staple food raw material, and an important source of food and feed. It has been planted in my country for 5,000 years and is the fourth largest crop in China. my country's soybean planting range is wide every year, and with the adjustment of agricultural production structure, the planting area is still expanding year by year. Weeds in soybean fields show the characteristics of many types, rapid emergence, high density, and vigorous growth. The area of ​​weed damage accounts for more than 53.4% ​​of the total planting area. Therefore, the annual loss of soybeans is 5%-20%, or even more than 30%. Weed damage It has posed a serious threat to the safe production of soybeans. There a...
