Problems solved by technology

[0005] Now people try to prepare a variety of botanical pesticides to prevent and control plant diseases and insect pests, but there are common problems such as easy decomposition of active ingredients, limited duration of action, and short shelf life. Some people try to add white carbon black, light calcium, attapulgite Pesticide carriers such as soil and bentonite can be used to improve such problems, but most of the above-mentioned pesticide carriers have problems such as high surface acid value (pKa<1.8) and strong water absorption capacity (up to 15%), and the effect on pesticide promotion is not obvious
