1results about How to "Rain resistant" patented technology

The application provides a spraying agent for preventing and treating snails and a preparation method and application thereof, and belongs to the technical field of pesticides. The spraying agent comprises ginkgo leaf extract, psoralea corylifolia fruit extract, bloodgrass extract, modified chitosan, hydroxypropyl-beta-cyclodextrin, tetrahydro-piperine, eucalyptol, polyvinyl alcohol, surfactant, dispersant and water. The spraying agent has both contact killing and stomach poisoning effects by using three plant source extracts as snail killing active ingredients. Tetrahydro-piperine and eucalyptol are compounded as penetration enhancers, which can effectively open the snail body surface channel, improve the penetration rate and bioavailability. The modified chitosan and polyvinyl alcohol form a water-resistant film skeleton, and the inclusion protection of hydroxypropyl-beta-cyclodextrin, so that the spraying agent forms a water-resistant protective film on the surface of plants or buildings. The spraying agent has the advantages of high efficiency, rainwater resistance, long persistence and the like, and can be widely applied to the prevention and treatment of snails on the surfaces of crops, flowers, lawns and buildings.
