Problems solved by technology

[0002] With the large-scale use of herbicide products in cornfields for many years, many problems have emerged in the control of weeds in cornfields: (1) Weed resistance is prominent. In recent years, due to the increasing use of herbicides year by year, Leading to the rapid development of herbicide resistance, and even "super weeds" resistant to multiple herbicides have appeared in some areas; (2) The harm of perennial weeds has become a major problem; (3) The killing of herbicide varieties The grass spectrum needs to be expanded and the duration of soil control chemicals should be extended; (4) The demand for broad-spectrum, selective and easy-to-use herbicide varieties is more urgent
[0003] Since the development speed of new herbicide active ingredients is far from being able to solve various problems in weed control, we can only solve the existing problems through the compounding of different active ingredients

Abstract

The invention relates to a compound herbicide containing s-metolachlor, and belongs to the field of pesticide compound preparations. The active ingredient of the herbicide is prepared by compounding of the s-metolachlor and a triazine herbicide, wherein the triazine herbicide is one selected from terbuthylazine, terbutryn, ametryn and prometryn, and the mass percentage ratio of the s-metolachlor to the triazine herbicide is (1:40)-(40:1). The compound herbicide provided by the invention is used for preventing and removing weeds in corn fields, can improve the preventing and removing effects onthe weeds, reduces the usage amount of pesticides, and simultaneously solves the problem of weed resistance existing in the prior art.
