Abstract

The invention relates to a herbicide composition which is applied to peanut, soybean and cotton fields and can prevent and eliminate monogenus and dicotyledonous weeds simultaneously. The herbicide composition comprises the following components in percentage by weight: 3 to 96 percent of oxadiazon, 3 to 96 percent of S-metolachlor, 1 to 20 percent of auxiliary agent, and 5 to 95 percent of solvent and carrier. The herbicide composition can overcome the shortages that the current peanut field herbicide has single performance, a large number of weeds generate resistance to acetochlor, weed community generates succession, and various malignant weeds such as copperleaf, pieprint, and the like are difficult to prevent and eliminate, and the like. The herbicide composition has the advantages of wide herbicide controlling spectrum, high weed killing efficiency, low using cost, and safety to peanuts, soy beans and cottons, and can remarkably retard and control the generation of weed drug resistance and the weed community succession.

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, soybean and cotton fields. Background technique: [0002] With the reform of the farming system and changes in international trade, the planting area of ​​peanuts, soybeans, and cotton has expanded year by year. There are many kinds of weeds in peanut, soybean, and cotton fields, which compete with crops for glory, fertilizer, and water, and can also break through mulch, which is an important factor causing crop yield loss. The herbicides used in peanut, soybean and cotton fields are mostly soil treatment herbicides. In peanut and soybean fields, acetochlor and trifluralin are mainly used. In cotton fields, acetochlor and trifluralin are mainly used. The long-term continuous application of Lingling has increased the number of weeds resistant to it year by year, and due to the selectivity of herbicides s...
