Abstract

The invention belongs to the technical field of the pesticide, and relates to herbicide, which comprises phenoxy ethyl alachlor of active ingredient formula (1). The herbicide is of suspension agent; by utilizing the herbicide, the problem that when the phenoxy ethyl alachlor in the formula (1) is used for weeding out the phenoxy ethyl alachlor in the formula (1) cannot uniformly enter the grass to cause the waste of partial phenoxy ethyl alachlor and to reduce the weeding effect can be solved.

Description

technical field The invention belongs to the technical field of pesticides, and relates to a herbicide. The active ingredient of the herbicide is phenoxypyramid of the formula ①, which is mainly used for controlling broad-leaved weeds and Cyperaceae weeds in paddy fields. The herbicide has been improved in two aspects. On the one hand, the dosage form of the herbicide is made into a suspension concentrate, so that the active ingredient formula ①, phenoxypyramid, can enter the weeds evenly; The ratio of the components is optimized, so that the suspension rate of the herbicide is improved, and the efficacy of the herbicide can be fully exerted. Background technique China is the world's largest producer and consumer of rice. The perennial sown area of ​​rice is about 28-32 million hectares, and a large number of weeds occur in rice-growing areas. According to statistics, there are more than 200 species of weeds in rice fields across the country, among which There are about 4...
