Herbicide composition for rape field

Abstract

A composite herbicide for rape field contains picloram (0.1-99 Wt%), benazolin-ethyl (0.1-99 Wt%) and assistant (rest).

Description

Technical field: [0001] The invention relates to an agricultural herbicide composition, in particular to a rapeseed field herbicide compound compounded with amilorolic acid and oxabutyl. Background technique: [0002] my country is the world's largest producer of rapeseed, and the current rapeseed planting area and total output account for about 1 / 3 of the world. Rapeseed is an important economic oil crop in my country, which can be divided into winter rapeseed and spring rapeseed according to the cultivation system. The harm of weeds in rapeseed field is an important factor affecting the yield and quality of rapeseed. The area of ​​winter rape weed damage in the Yangtze River Basin is as high as 30 million mu, and the area of ​​weed damage in spring rape production area in Northwest China is as high as more than 3 million mu. [0003] Rapeseed weeds are mainly divided into monocotyledonous weeds and dicotyledonous weeds. The monocotyledonous weeds in the winter rapeseed ...

AI Technical Summary

Problems solved by technology

As the density and frequency of Asteraceae, Leguminous and some Polygonaceae weeds sensitive to clopyralid decrease year by year, they become secondary dicotyledonous weeds in rapeseed fields, and the control effect of clopyralid and clopyralid is poor The density of Chenopodiaceae, Umbelliferae and other weeds will inevitably increase and gradually become the dominant dicotyledonous weeds in rapeseed fields, which are difficult to control

In addition, the price of clopyralid is relatively high, and the cost per mu of farmers is too high to promote it on a large scale
