Problems solved by technology

[0017] At present, the prevention and control of stored grain pests in my country and the world mainly adopts chemical control. The resulting pesticide residues, environmental pollution, and resistance to stored grain pests are becoming more and more serious, which forces people to seek other safer and more effective pest control measures. , to replace the highly toxic chemical agents currently used in large quantities with new biological source insecticides, and it is urgent to develop green and long-acting biological food protection agents

Abstract

The invention relates to a bacteriostatic mildew-resistant insecticidal sustained release agent prepared from a sol / gel also used as an insect attractant. The agent is prepared into a sol plastic and a sol forming preparation with a microemulsion technology, a sol technology and the like according to different use conditions. The agent which treats an insect growth regulator (IGR) as a main component and essential oil and / or a low-toxicity high-efficiency insecticide, a bactericide, a penetrant, a water-soluble solvent, a stabilizing agent, an insect attractant, a film forming sustained release agent and the like as assistant components to satisfy prevention and control demands of different places. The agent of the invention, which has the advantages of wide insecticidal spectrum, low toxicity and high efficiency, ovum killing, insect growth inhibition, long persistent period, difficult resistance generation, bacteriostasis and mildew resistance, and low residual, can eliminate the pollution caused by unbalanced drug application, and is in favor of the ecological environment. The agent which is used for killing, preventing and controlling pests, mites and mildews on storage objects of stored grains, tobaccos, medicines, leathers, clothes, books, archives, history relics and the like and plants can reduce the loss caused by the pests and the mildews of the stored objects, the grains and the plants.

Description

technical field [0001] The present invention relates to a kind of bacteriostatic, anti-mildew, insecticidal slow-release agent prepared by itself as an insect attractant sol / gel, more specifically to a microemulsion, slow-release agent containing insect growth regulator (IGR) and plant essential oil, etc. Microemulsions, silica sol preparations, and the present invention also relates to the application of storage protection agents in stored grains, tobacco, medicinal materials, food, leather, clothing, books, archives and historical relics. It belongs to the field of green and pollution-free storage protection agent. Background technique [0002] The occurrence and harm of crop diseases, insect pests and rats seriously restrict the development of high-quality agriculture and sustainable agriculture. According to the statistics of the Food and Agriculture Organization of the United Nations (FAO), the loss of world grain production due to diseases, insect pests, weeds and rat...
