Abstract

The invention discloses a weeding pesticide composition containing nicosulfuron. 2-(6-fluoro-2-pyridine acyloxy)-N-(4-fluoro-phenyl)-N-(1-methyl ethyl)thioacetamide (TAM-5) and nicosulfuron serve as active ingredients and form the weeding pesticide composition together with auxiliary ingredients acceptable in pesticides, wherein the weight ratio of TAM-5 to nicosulfuron is 20:1 to 1:30. The two active ingredients have a synergistic effect after being combined, a weeding spectrum can be expanded, no antagonism occurs, and crop safety is enhanced. The synergistic weeding pesticide composition can effectively prevent and kill off annual grassy weeds and broad-leaved weeds, can inhibit part of perennial weeds, is particularly suitable for corn field weeding, remarkably improves a weeding effect, and is safe to cash crop soybean.

Description

technical field [0001] The invention relates to a herbicidal pesticide composition, which is especially used for weeding in cornfields, rapeseed fields, soybean fields, tea gardens and other farmlands and non-cultivated lands. Background technique [0002] Weeds in farmland have plagued the development of agricultural production since the day humans started farming. Every year around the world, crop yields are reduced by about 14% due to weed damage, and the resulting economic losses are as high as tens of billions of dollars. Under the current level of prevention and control in our country, the annual direct economic loss caused by weeds in farmland is as high as 90 billion yuan. Increase the attention and investment in weed scientific research and control work to ensure high grain yield, increase farmers' income and rural economic development. Taking Sichuan Province, one of the largest agricultural provinces in the country, as an example, there are currently 654 species...
