Abstract

The invention relates to a weeding composition containing halauxifen-methyl, pyraflufen-ethyl and pyroxsulam. The weeding composition comprises the following effective components: halauxifen-methyl, pyraflufen-ethyl and pyroxsulam at the ratio of (1-10) to (1-10) to (1-10) in parts by weight. The weeding composition has a synergetic effect; the annual weed control effect in a wheat paddock is obviously superior to that of individual use of each single dosage; a herbicide controlling spectrum is expanded; meanwhile, the dosage of a pesticide is reduced; the environmental pollution is relieved; and the weed drug resistance is delayed.

Description

technical field [0001] The present invention relates to a pesticide herbicidal composition and its application field, in particular to a ternary herbicidal composition with hachlorpyrid, pyraclofen and acesulfame as active ingredients, which is mainly used for controlling annual weeds in wheat fields . Background technique [0002] At present, chemical control is still the most important means in the comprehensive management of farmland weed damage. However, long-term continuous high-dose application of a single chemical herbicide is likely to cause environmental pollution, phytotoxicity to crops, and weeds are prone to resistance. At the same time, due to the complex grass phase and various types of weeds in the field, such as grass weeds, broad-leaved weeds and other weeds, the use of a single species can no longer effectively solve this problem, and it will show a certain aspect. Defects. Reasonable compounding of chemical herbicides has many advantages such as expandi...
