Abstract

The invention relates to a weeding composition. The weeding composition comprises the following active components of florpyrauxifen and oxaziclomefone according to a weight ratio of 1:50 to 50:1. Theweeding composition is suitable for rice fields, and has the advantages that the generation and prevalence of rice weeds can be effectively prevented and treated; the weeding spectrum is broad, the efficiency is high, the use cost is effectively reduced, and the drug resistance of weeds is decreased.

Description

technical field [0001] The invention relates to the technical field of pesticides, and specifically designs a herbicidal composition containing halopyridine and oxazicone. technical background [0002] Rice is one of the main economic crops in the world; agricultural weeds endanger the growth and development of agriculture in agricultural production, and affect the yield and quality of agricultural products; weeds in rice fields are the biggest factor affecting rice production reduction, and chemical weeding technology has become the mainstay of weed control. important means. [0003] In recent years, the extensive use of herbicides has not only brought benefits to growers, but also made the use of pesticides toxic hazards and the resulting pesticide residues (residence), resistance (resistance) and the so-called rampant (resurgence) The 3R problem is getting more and more serious. In order to give full play to the advantages of herbicides, improve their weeding effect, an...
