A pure "live microbial pesticide", which is based on insect viruses and has no residues in the prevention and control of tea pests, passed the test a few days ago and started to be put into mass production. This is an effective guarantee for pest control in tea that frequently encounters “green barriers†and is of great significance for restoring the status of China’s tea in the international market.
The “Live Microbial Pesticide†developed by the Institute of Insect Virus Research, School of Life Sciences, Wuhan University and Wuhan Wuda Oasis Biotech Co., Ltd. was named “Wu Da Oasis Tea Garden†and was approved by the State Development Planning Commission as a “National High-tech Industrialization Demonstration Projectâ€. One of the biological high-tech achievements. It is based on the combination of the most virulent and safe insect baculoviruses and other microorganisms co-invented and used by the UN Food and Agriculture Organization and the World Health Organization. Pure biological insecticides for intellectual property.
“Wu Da Oasis Tea Garden†changed the traditional method of using chemical pesticides to kill and contact the tea pests in the past, and used a new insecticidal concept of artificially creating “bugs†to fight poison with drugs, allowing the virus to directly enter the gastrointestinal tract of the pests and combine with the midgut cells. Replicate it and cause it to quickly die of poisoning. After the death of the larvae, the living virus still survives, and the proliferation can spread among the population and cause epidemics, continuously killing eggs and eggs. It is reported that this is the first domestic pure biopesticide that has passed the national appraisal and can be directly used for the large-scale prevention and control of organic tea in tea pests, tea caterpillars and tea leaf roller moth. The pesticide can be directly used for the prevention and control of tea pests, has the advantages of safety, no residue, no damage to tea quality, and meets the requirements of the EU organic food production. Moreover, its integrated prevention and control costs are relatively low, and the cost and man-hour per mu are one-tenth of that of chemical pesticides.
