Abstract

The invention provides a complex herbicidal composition. The complex herbicidal composition comprises a first active component, namely penoxsulam, a second active component, namely bentazone, and a third active component, namely MCPA (2-methyl-4-chlorophenoxyacetic acid) sodium or a derivative thereof, and the mixture ratio range by weight of the three active components is (0.1-40): (1-100): (1-100). According to the complex herbicidal composition provided by the invention, the penoxsulam, the bentazone and the MCPA-sodium or the derivative thereof are used for ternary compounding, so that the new composition obtains gain effects in the control of broadleaf weeds and sedge weeds in a paddy field and better effects on controlling the gramineous and broadleaf weeds and the sedge weeds are particularly during the tillering stage of paddy rice. In addition, the using quantity of the bentazone and the MCPA-sodium or the derivative thereof during the tillering stage of the paddy rice can be reduced, and the safety of grains can be improved.

Description

technical field [0001] The present invention relates to a compound herbicidal composition, in particular to a new compound herbicidal combination of three-component compounding of penoxsulam, bentazone and methyclochloride or derivatives thereof, and applied to paddy fields thing. 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 cou...
