Tralkoxydim-containing wheat field post-emergence compound herbicide

Abstract

The invention discloses a tralkoxydim-containing wheat field post-emergence compound herbicide which comprises the following effective components: isoproturon, tralkoxydim and pyroxsulam, wherein themass ratio of the isoproturon to the tralkoxydim to the pyroxsulam is (10-70):(1-40):(1-10). The herbicide disclosed by the invention is remarkable in effect, and is low in application amount and lowin cost when being compared with single agents of isoproturon, tralkoxydim and pyroxsulam, the herbicide controlling spectrum can be widened, the control effect, the fresh weight prevention effect andthe comprehensive fresh weight prevention effect of monocotyledon weeds and dicotyledon weeds in fields can be remarkably improved, and the herbicide is safe to field crops and remarkable in fast-acting property. Weeds in a whole growth period of a crop can be prevented and controlled after one time of application, and the herbicide is environmentally friendly, free of residue and highly safe tonext-stubble crops. The herbicide is a relatively ideal herbicide for stem and leaf treatment on resistant weeds such as ryegrass, beckmannia syzigachne, bromegrass and resistant broad-leaf weeds suchas galium aparine and veronica polita in wheat fields.

Description

technical field [0001] The invention relates to the field of pesticides, in particular to a post-emergence herbicide for wheat fields containing trimethylbenzone. Background technique [0002] Wheat is a gramineous plant widely planted all over the world. It is one of the food crops with the widest distribution, the largest area, the highest total output, the largest trade volume, and the highest nutritional value. Its output is the second largest food crop in the world. , second only to corn. The main weeds that affect the yield of wheat. The main weeds in the wheat field are: Artemisia sobani, quinoa, shepherd's purse, Maijiagong, wheat bottle grass, mother-in-law, spinach, pig's weed, chickweed, big nest vegetable, see Oatmeal, wild oats, buckwheat, brome, oatmeal, etc. At present, the main herbicides used to control weeds in wheat fields are tribenuron-methyl and fenoxaprop-p-ethyl, etc. Due to long-term use, the resistance increases, resulting in a large amount of app...

Problems solved by technology

[0006] However, the above-mentioned three kinds of pesticides have limitations in herbicidal effect, and they cannot be effective for all weeds in the wheat field at one time, thus increasing the amount of pesticide application and the cost of pesticide application
