AI Technical Summary
In existing technologies, weeds in grain fields have developed resistance to conventional herbicides, making them difficult to eradicate effectively.
Using bensulfuron, sulfopyrazosulfuron, and pyrfluthrin as the main raw materials, water-dispersible granules are prepared. Through air jet milling and kneading granulation processes, uniform powder with a particle size of 10-15μm is formed. The granulation temperature is 20-45℃, and wet granules of 0.4-2mm are obtained. After drying and sieving, water-dispersible granules are prepared.
It significantly improves the weed control effect on grass and broadleaf weeds, increasing the efficiency by 40-50%. It has stable physical and chemical properties, is not easily decomposed, is easy to use, avoids phytotoxicity, has good flowability, and does not stick to the cell wall.
