Problems solved by technology

However, the development cost of new active ingredients is high, the development cycle is long, and it can never keep up with the speed of weed resistance
Other methods, such as crop layout adjustment, rotation of different pesticides, etc., are difficult to achieve obvious effects in actual operation.

Abstract

The invention provides a wheat field weeding composition and application thereof. The composition comprises effective components and auxiliary components, wherein the effective components include triazolamide and tembotrions according to the weight ratio of 1:(0.1-20). According to the wheat field weeding composition and the application thereof, by screening the formula of the triazolamide and tembotrions, the triazolamide and tembotrions have a remarkable synergistic effect on paddy field weeds within a certain composition ratio range, the limitation of two or more types of herbicides on theweed control spectrum, protection effect and safety is eliminated, the triazolamide and tembotrions are different in action mechanism, by reasonably combining the triazolamide and tembotrions, the weed agent resistance can be delayed, the weed control spectrum is expanded, the agent lasting period is prolonged, and the triazolamide and tembotrions have a good prevention effect on grassy weeds, broadleaf weeds and nutgrass flatsedge in a field and especially have a good prevention effect on malignant weeds difficult to prevent and remove; meanwhile, the agent effect is improved, the field dosage of the effective components is reduced, the production and use cost is reduced, and the pesticide residues and environment pollution are reduced.

Description

technical field [0001] The invention belongs to the technical field of pesticides, in particular to a wheat field herbicide composition and its application. Background technique [0002] Trifencarbazone (test code: HOK-201, common name: ipfencarbazone) is a research and development company started by Hokko Chemical Industry Co., Ltd. in Japan. Application, labour-saving herbicide applied by means of a tractor-mounted device during rice transplanting. Japan Hokko Chemical Industry Co., Ltd. synthesized heterocyclic compounds and found that 1-aryl-4-carbamoyl-1,2,4-triazolinone derivatives are effective against barnyard weeds and a variety of rice field weeds High activity. In the end, trifamid was selected as the optimal compound, which is a triazolinone herbicide for paddy fields, which is highly effective against gramineous weeds, annual sedges and some annual broad-leaved weeds, especially for barnyardgrass. It has a long validity period and is highly safe even when ric...
