Abstract

The invention relates to a compound herbicide composition and in particular relates to a compound herbicide composition which is prepared by carrying out ternary compounding on penoxsulam, cyclosulfamuron and methyl-4-chlorophenoxyacetic acid or derivatives thereof and is applied to rice fields. The compound herbicide composition comprises a first active ingredient, a second active ingredient and a third active ingredient, wherein the first active ingredient is penoxsulam; the second active ingredient is cyclosulfamuron; the third active ingredient is methyl-4-chlorophenoxyacetic acid or derivatives thereof; and the weight percent ratio of the three active ingredients is (0.1-50):(1-100):(0.1-50). By carrying out ternary compounding on penoxsulam, cyclosulfamuron and methyl-4-chlorophenoxyacetic acid or derivatives thereof, the obtained new composition has beneficial effects on control of grassy, broadleaf and cyperaceae weeds compared with each of the three chemical substances, and simultaneously reduces the use cost.

Description

technical field

[0001] The present invention relates to a compound herbicidal composition, in particular to a compound herbicide compounded with penoxsulam, cyprosulfuron-methyl, metethentrachlor or derivatives thereof and applied to paddy fields combination. Background technique

[0002] Rice is one of the main food crops in the world. Nearly half of the world's population, including almost the entire population of East Asia and Southeast Asia, live on rice, and its production covers all continents except Antarctica. In the late last century, the average annual rice output in the world was about 400 billion kilograms, and the planting area was about 145 million hectares. Rice is also the most important food crop in my country. my country's rice sowing area accounts for 1 / 4 of the country's food crops, about 35 million hectares per year, while the output accounts for more than half. Regardless of the planting area and output, it ranks first in my country's food crops. ...
