Problems solved by technology

[0002] Soybean is an important crop in my country. Soybean is often harmed by various weeds from sowing to harvest. Due to the influence of climate and soil quality, the types and numbers of weeds vary from region to region. Chemical agents are used to remove weeds in wheat fields. The most effective method for weeds. At present, the main herbicides used to control weeds in soybean fields are mostly one or two types of effective herbicides. Due to long-term use, the resistance increases, resulting in a large amount of pesticides, polluting the environment, and increasing farmers' application of weeds. In order to solve the above-mentioned disadvantages, the present invention selects several novel medicinal ingredients with control and herbicide effects, and develops a soybean field herbicide and its preparation method
