Diatomite is a kind of siliceous rock, mainly found in China, the United States, Japan, Denmark, France, Romania and other countries. It is a biogenic siliceous sedimentary rock composed mainly of the remains of ancient diatoms. Its chemical composition is mainly SiO2, which can be expressed as SiO2•nH2O, and its mineral composition is opal and its varieties. The reserves of Diatomite in China are 320 million tons, and the prospective reserves are more than 2 billion tons, mainly concentrated in east China and northeast China, of which there have large reserves is in Jilin, Zhejiang, Yunnan, Shandong, Sichuan provinces.
tChina’s grain reserves big, long storage period, pest damage is serious, for a long time mainly using phosphine chemicals such as prevention and control, has achieved some success, but the PH3 pollute the environment, which are toxic to staff and many pests had serious drug resistance on its problems such as more and more prominent, urgent needs to solve.
Diatomite insecticides have gradually become an important means of controlling stored grain pests because of their low toxicity to mammals, no chemical residue and no pollution to the environment. It is an ideal substitute for phosphine and other chemical agents, which meets the needs of food security and green storage. It has huge research and development value and broad application prospect.At present, the research and development of diatomite insecticide application technology and application equipment in China are still in the initial stage. It is urgent to develop the application technology and high-efficiency application equipment suitable for grain storage in China to improve the pest control effect, reduce labor intensity, and provide technical support for promoting the large-scale application of diatomite insecticide in China.
