ROS-Responsive Polymeric Micelle for Improving Pesticides Efficiency and Intelligent Release.
JOURNAL OF AGRICULTURAL AND FOOD CHEMISTRY(2020)
Abstract
The low utilization rate of pesticides causes serious problems such as food safety and environmental pollution. Stimulus-responsive release can effectively improve the utilization rate of pesticides. Reactive oxygen species (ROS) burst, as an early event of plant-pathogen interaction, can stimulate the release of pesticides. In this work, a polymeric micelle with ROS-responsive was prepared and then Validamycin (Vail) was loaded into polymeric micelle to prepare Vail-loaded polymeric micelle. The Vail-loaded polymeric micelle displayed excellent ROS-dependent release kinetics. In vitro and in vivo antifungal experiments confirmed that the Vail-loaded polymeric micelle could improve antifungal efficacy against Rhizoctonia solani than with the Vail reagent. Therefor; as a biostimulation and controlled release system, ROS-responsive polymeric micelles can improve the utilization rate of pesticides and alleviate the problem of food safety and environmental pollution.
