Problems solved by technology

[0010] These herbicide single doses have certain problems, some remain in the soil for a long time, and some are easy to cause phytotoxicity to subsequent crops when used in farmland, and long-term single-dose pesticides are likely to cause weeds to develop resistance

Abstract

The invention relates to the technical field of agricultural pesticides, in particular to a soybean field weeding composition and a preparation thereof. The soybean field weeding composition consists of cloransulam-methyl and fomesafen. The herbicide namely the weeding composition has obvious synergized action, and compared with a single preparation, the dosage and the dosage times are greatly reduced, the weeding composition has the advantages of safety, high efficiency, environmental-friendliness and the like, and the generation of drug resistance of weeds is delayed.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a soybean field herbicide composition and its preparation. Background technique [0002] Soybeans, also known as soybeans, green beans, and black beans, are the most important beans in the world. They originated in China and have been planted in my country for 5,000 years. important crops in the West. Soybean is the most nutritious and easily digestible food in the legume family. It is rich in protein and is an important source of food and feed. [0003] There are many kinds of weeds in soybean fields. The common ones are barnyardgrass, crabgrass, foxtail, quinoa, amaranth, polygonum, commelina, nightshade, purslane, lettuce, cocklebur, field bindweed, and velvet These weeds have seriously affected the yield and quality of soybeans. The use of chemical herbicides is the main method to solve this problem. At present, the herbicides commonly used in soybean fields include imaz...
