Australian/Chinese storage pesticide project
A joint project by Australian and Chinese researchers is seeking to develop a more refined version of diatomaceous earth for use as an insecticide to control pests in stored grain. The “micro-fined, non-crystalline silicon dioxide dust” is said to be effective at a rate 10-20 times lower than standard diatomaceous earth and to achieve faster control. Laboratory tests on a range of insects have demonstrated its “strong potential” as an insecticide. The research is being carried out by scientists at the Western Australia Department of Agriculture and Food (Perth), and the Chinese Academy of Cereal Science (Beijing).
