Weeding composition containing penoxsulam and bensulfuron-methyl

Abstract

The invention discloses a weeding composition containing penoxsulam and bensulfuron-methyl, which comprises active ingredient a and active ingredient b, wherein the active ingredient a is penoxsulam, the active ingredient b is bensulfuron-methyl, the weight ratio of the a to the b is 1-90:90-1; preferably, the weight ratio of the a to the b is 1-50:50-1, and particularly preferred, the weight ratio of the a to the b is 1-10:10-1. The active ingredients of the composition account for 8 to 95 percent of the total weight of the composition, and the balance is agriculturally acceptable pesticide adjuvant.

Description

technical field

[0001] The invention belongs to the field of agricultural plant protection, and relates to a herbicidal composition with improved performance, especially a herbicidal composition containing penoxsulam and bensulfuron-methyl. Background technique

[0002] In recent years, the variety of herbicides used in rice fields has developed rapidly, and the varieties have been continuously improved and perfected. Herbicides such as diphenyl ethers, thiocarbamates, amides, quinoline carboxylic acids, and sulfonylureas have emerged successively, forming A relatively complete chemical herbicide system adapted to different rice cultivation methods has become an indispensable and very important yield-increasing measure in the world's rice production. However, with the continuous use of many herbicide varieties in large areas of rice fields, there will inevitably be some problems that need to be faced and should be solved seriously: mainly the outstanding resistance of weeds,...
