Abstract

The invention discloses an abamectin-cyanobacteria anti-ultraviolet sustained-release microcapsule insecticide and a preparation method thereof. In parts by weight, the components and contents thereof are: 0.5-50 parts of abamectin, 5 parts of blue-green algae powder -50 parts, surfactant 1-20 parts, easily degradable polymer 0.5-20 parts. The present invention utilizes blue-green algae as a pesticide carrier to adsorb abamectin, and relies on its own natural properties to delay the decomposition of abamectin due to ultraviolet light, and can be used as an organic fertilizer to increase production of crops to realize waste utilization of pollutants; secondly, using The degradable polymer is used as the coating agent, which is beneficial to environmental protection. Thirdly, the controlled release of abamectin is achieved by using the slow-release technology, which reduces the toxicity of abamectin to humans and animals.
