Abstract

The invention relates to the technical field of herbicides, in particular to a composition of a peanut field herbicide and application of the composition. Active components in the herbicide composition are composed of sulfentrazone and clethodim according to the weight ratio from 0.01:1 to 100:1, the active components account for 1-95% of the total weight of the herbicide composition, and the herbicide composition is one of wettable powder, water-dispersible granules, an oil suspending agent, a dry suspending agent, granules, missile oil, an emulsion in water, a microemulsion and a suspendingemulsion. After the herbicide composition is prepared, the herbicide controlling spectrum can be expanded; meanwhile, the herbicide composition prevents and removes broadleaf weeds and grassy weeds and has a remarkable synergistic effect.

Description

technical field [0001] The invention relates to the technical field of herbicides, in particular to a herbicide composition for peanut fields and its application. Background technique [0002] Peanut is an important source of edible oil and protein feed in my country. It has the characteristics of strong adaptability, wide application and high economic value. It is planted in most areas of my country. Peanuts have a long growth period and many types of weeds, which have a great impact on the yield of peanuts. [0003] Sulfentrazone is a triazolinone herbicide that controls most broadleaf weeds, grasses and sedges. It has a good control effect on broad-leaved and sedge weeds such as retroflexus, amaranth, quinoa, datura, crabgrass, foxtail, cocklebur, goosegrass, and Cyperus cyperus. However, sulfentranacil kills weeds slowly and has a long residual period in the soil. [0004] Clethodim is a selective herbicide used to control various grass weeds in various broadleaf crop...
