Abstract

The invention belongs to the technical field of pesticide herbicides and particularly relates to a herbicide composition containing oxadiazon and S-metolachlor. The herbicide composition is applicable to peanut, soybean, cotton and wheat paddock. The weight ratio range of oxadiazon and S-metolachlor which are used as effective components is (10 to 1) to (1 to 40). Through the herbicide composition containing oxadiazon and S-metolachlor, the herbicide controlling spectrum is expanded; the effect is enhanced; the rapid occurrence of weed resistance caused by control and elimination via single herbicide can be avoided; the occurrence of the weed resistance is delayed; the usage cost is reduced; the environment pollution is alleviated.

Description

technical field [0001] The invention belongs to the technical field of pesticide herbicides, and in particular relates to a herbicide composition containing oxadiazone and refined metolachlor. Background technique [0002] Wheat, rice, peanuts, soybeans, cotton and other crops are planted in a large area in my country. Herbicides are currently a common measure for weed control in farmland, which plays an important role in promoting yield increase and saving planting costs. However, with the long-term and large-scale promotion and application of herbicides, the problems of weed resistance, population succession and phytotoxicity in chemical weed control in farmland are becoming more and more serious, which seriously affects the high yield and harvest of crops and the safety of subsequent crops. [0003] Oxadiazone, CAS number is NO. 19666-30-9; EINECS is 243-215-7; molecular formula is C 15 h 18 Cl 2 N 2 o 3 ; The molecular weight is 345.22. It is used to control a var...
