Problems solved by technology

In addition, since wheat weed control and disease control are in the same period, there is a phenomenon of mixed use of herbicides and fungicides in the actual application process. Research on wheat phytotoxicity) involves the safety of the mixed application of herbicides and fungicides on wheat, but there is no research on the compound synergy of herbicides and fungicides

Abstract

The invention relates to the technical field of pesticides, and discloses a tribenuron-methyl, 2-methyl-4-chloro sodium and tebuconazole compounded weeding composition, and the mass ratio of the composition of tribenuron-methyl and 2-methyl-4-chloro sodium as an active component A to tebuconazole as an active component B is 0.5 to 30: 1. The weeding composition disclosed by the invention has an obvious synergistic effect on agricultural weeds, and is good in fast-acting property and low in toxicity to people and livestock; besides, tribenuron-methyl, 2-methyl-4-chloro sodium and tebuconazole have different action mechanisms, can delay the drug resistance of weeds, and are ideal herbicides.

Description

technical field [0001] The invention belongs to the technical field of pesticides, in particular to the technical field of herbicides, and specifically relates to a compound composition of tribenuron-methyl, sodium 2-methyl-4-chloride and tebuconazole, and its application in preventing and controlling agricultural weeds. Background technique [0002] Wheat is one of the important food crops in my country, but weeds in wheat fields have a large amount of seed reproduction and high field density, occupying the space above and below the ground, affecting the photosynthesis of wheat, aggravating the breeding of wheat pathogens, and harming the growth of wheat. Wheat production has been severely affected, with typical yield losses of more than 10 percent. [0003] In my country, tribenuron-methyl is widely used to control a variety of broad-leaved weeds in wheat fields. In order to solve the resistance problem caused by its single use, most products are compounded with it to expan...
