Description

Compound herbicide

Technical Field

The invention relates to the technical field of pesticides, and particularly relates to a compound herbicide.

Background

In general, food is an indispensable part for human life and occupies an important proportion in production and life when people eat food.

The rice is used as an important grain crop in China, the yield of the rice is directly related to the livelihood of people and even the national safety, more and more weed drug resistance is caused due to the fact that the herbicide is used in a large area in a single paddy field for a long time, the occurrence and spread of the drug resistance of gramineous weeds and broadleaf weeds in the paddy field are caused, in most cases, the weed species in the paddy field are greatly different, the single herbicide is difficult to solve all weeds in the paddy field, the continuous use of various herbicides is easy to generate the drug resistance, the insect-resistant spectrum is narrow, and the comprehensive and effective protection cannot be achieved
