Problems solved by technology

Penoxsulam is very safe for rice, and it can be used from the first leaf stage of rice to before harvesting. However, with the increase in the number of years and doses of use, weed resistance is getting stronger and stronger. Penoxsulam alone Amines have less and less effect on weeds and cannot meet production needs

Abstract

The invention relates to a weeding composition containing penoxsulam, anilofos and propanil. The weeding composition has synergistic effects, and a weight ratio of the penoxsulam to the anilofos to the propanil is (1.5-2.5):(10-30):(100-200), and preferably 2:30:150.

Description

technical field [0001] The invention belongs to the field of herbicide compounding, and specifically relates to a herbicidal composition containing penoxsulam, saponin and propannil. The herbicidal composition is efficient and thorough in weeding, simple and convenient to use, and relatively low in cost. And safe for crops. Background technique [0002] The control of older barnyardgrass in direct-seeding rice is a difficult problem in production weeding. Many herbicides are difficult to control effectively at high doses, and it is easy to cause crop phytotoxicity. One of the current effective methods is to use the synergistic effect of each component through reasonable compounding to reduce the dosage of a single agent, thereby reducing the risk of phytotoxicity and improving the control effect to solve the problem of old barnyard grass. [0003] Penoxsulam is a selective post-emergence herbicide developed by Dow AgroSciences. It belongs to the triazolopyrimidine sulfonami...
