Problems solved by technology

It can control barnyardgrass, goosegrass, crabgrass, foxtail and other annual monocotyledonous weeds and some dicotyledonous weeds, but the control effect on dicotyledonous weeds is significantly lower than that on monocotyledonous weeds

Abstract

The invention relates to a peanut field weeding composition which comprises a mixture prepared by effective ingredients of oxadiazon and napropamide by the weight percentage of 1:0.1 to 1:40. A universal preparation method is adopted to prepare the mixture into pesticides containing 1 to 99 weight percentage of the effective ingredients, such as miscible oil, powder, suspending agents, and the like. The invention has reasonable prescription, is suitable for peanut fields, has higher prevention effect on single and double cotyledon weeds than expected prevention effect of mixed use and has obvious synergized action; in addition, the invention has simple preparation method and convenient implementation, reduces the cost, delays and controls the resistance of the weeds to the peanut field weeding composition and the generation of weed community succession, thereby being an currently ideal herbicide for single and double cotyledon weeds in peanut fields.

Description

Technical field: [0001] The invention belongs to the field of pesticides, and relates to a herbicide composition, which is especially suitable for controlling weeds in peanut fields. Background technique: [0002] Peanut is the main oil crop in my country. With the adjustment of agricultural production structure, the planting area is expanding year by year. Due to suitable factors such as climate and farming system, weed damage has been serious over the years. The harm of weeds affects the needle pricking, burrowing, and fruiting of peanuts after flowering, and finally leads to different degrees of production reduction. The application of chemical agents to weed control is an effective means to control weeds in farmland. However, due to the long-term use of butachlor, acetochlor and other herbicides, weeds develop drug resistance, weed populations change, and the weed control effect decreases year by year. In order to solve these problems, there is an urgent need to develop...
