Also known as wetting agent. One of the pesticide additives. A substance that can make a solid pesticide that is insoluble in water or not moistened by water become wet with water.
The main function is to reduce the surface tension or interfacial tension of water, so that the solid surface can be wetted by water. It can make the insoluble pesticide in water mixed with water and prepare it into a suspension for use, and can make the liquid medicine moisten and expand on the surface of crops, insects and bacteria, so as to improve the control effect and reduce the occurrence of pesticide damage. Commonly used wetting agents such as tea wither, laundry detergent, and pull powder.
