Fungal killing pest bio-pesticides come out

A biological pesticide that uses fungi to kill pests has been successfully developed in Ningbo recently. This high-tech biological pesticide will play an important role in the development of pollution-free agricultural products. At present, the results have been applied for national invention patents. Compared with traditional chemical pesticides, this product does not contain any chemical toxic components, and pesticide residues cannot be detected even after harvesting agricultural products on the day after spraying. The product generally has a longer pot life, but the process is slightly slower than chemical pesticides. This achievement broke through the two major problems of traditional formulas and formulation processes. It uses highly effective insecticidal strains with independent intellectual property rights, produces hyphae through liquid phase fermentation, and then uses low-value glutinous rice as the main raw material, producing high purity through solid phase fermentation. Spore powder, and is distributed as an effective pesticidal formulation with inert mineral oil and biocompatible adjuvants. The product is mainly used for the prevention and treatment of locusts, leafhoppers and other sucking mouthpart pests on economic crops such as vegetables, fruits and tea. Retention period of up to 1 year or more, one-time application control effect can reach more than 70%, two consecutive applications (10 to 15 days interval) control effect of up to 90 or so, each efficacy can last for 2 to 3 weeks. The use of pesticides for non-environmental agricultural product-specific fungi for sucking mouthpart insect pests is still a technical gap in China, because the preparation of any other microorganisms (such as bacteria and viruses) cannot be effective against such pests. Such pests are found in vegetables and melons. Fruit, tea and other economic crops frequently cause disasters. In this sense, the advent of domestic fungal insecticides fills this gap and will provide guarantees for the sustainable development of pollution-free agricultural products. It is reported that the biological pesticide is expected to begin mass production in 2005.
