Dendritic polymers have the following advantages over conventional pesticides for the sustained release of pesticides:
1) has solubilization and reduces the amount of medicament used;
2) Reduce the loss of pesticides in the environment, increase the utilization rate of pesticides, and reduce the amount of pesticides;
3) Improve the adhesion of pesticides on the surface of plants, increase the retention and prolong the residence time;
4) Improve the penetration of pesticides on the surface of plants or pests and improve the efficacy;
5) Control the release rate of pesticides to make the agent functional and energy-saving; 6) Long-term effects can be achieved with one use;
7) It is rain and weather resistant and improves environmental stability.
Application examples are as follows:
The dendrimer was used as a pesticide carrier (CYD-MD844, CYD-MD1384, CYD-MD2524) and mixed with the herbicide dichlorophenoxyacetic acid (2,4-D) to study the pesticide 2,4-D. The sustained release effect shows that the dendrimer can coat the herbicide 2,4-D well, and its application in crop experiments shows that it has a good sustained release effect of pesticides, and traditional pesticides. Compared with the effect, the drug holding period can be increased by 2-4 times, and it has excellent rain resistance, weather resistance and other environmental stability and controllability of the sustained release period, and the release period can reach 1-3 months.
