Abstract

The invention discloses a rice field weed control composition and relates to the technical field of pesticide herbicides. The rice field weed control composition consists of effective components and aids, wherein the effective components comprise metamifop, bentazone and pyribenzoxim in a mass ratio of (1-30):(1-50):(1-30). The composition can be prepared into an oil suspension, water dispersion granules and wettable powder. The rice field weed control composition disclosed by the invention can be used in rice fields, is capable of preventing and treating broad leaf weeds and grass family weeds in rice fields, is a low-dosage high-efficiency weed control agent, and has the characteristics of being low in cost, wide in weed control spectrum and long in effect lasting period.

Description

technical field [0001] The invention relates to the technical field of pesticide herbicides, in particular to a paddy field herbicide composition. Background technique [0002] my country's rice planting area is about 450 million mu, and the area of ​​weeds in paddy fields is about 290 million mu, with an occurrence rate of 64.5%. There are more than 20 families and genera and more than 150 species of weeds in rice fields in my country. There are more and more types of difficult-to-control weeds in paddy fields. , weedy rice, stolon bentgrass and other weeds became the dominant malignant weeds. Due to changes in farming and cultivation methods, such as the increase in the area of ​​direct-seeding rice year by year, especially the increase in the area of ​​dry-directed direct-seeding rice, weeds entering paddy fields in dry fields are prominent problems in the current production practice, such as crabgrass, goosegrass, foxtail, Qianjinzi and so on. [0003] In recent years,...
