Biological and chemical pesticides are the same direction

It is reported that from the current perspective, insect virus insecticides are still difficult to completely replace the relevant chemical pesticides, but in the agricultural production will form insect virus insecticide and low toxic high efficiency low residual chemical pesticide coexist situation, which is also future A direction of pesticide development.

According to reports, an insect virus is a group of viruses that are pathogenic to insects. Insect viruses, as control methods for agricultural and forest pests and sanitary pests, have unique advantages. They have high host specificity, can kill pests without affecting natural enemies of pests, have a long duration of validity, do not pollute the environment, and are harmless to humans and livestock. Insect viruses exist in nature, and there have been no reports of insect viruses producing toxicity, pathogenicity, or response to aquatic products, birds, and mammals. Natural enemies such as grasshoppers, ladybugs, wasps, and parasitoids have also been reported. Non-toxic and highly safe. Insect virus formulations can be administered using existing plant protection devices. Insect virus insecticides will be the most promising living microbial pesticides in the 21st century.

It is understood that many features and advantages of biopesticides themselves are promising, but it is not possible to achieve market dominance or replace chemical pesticides in the short term, and its development itself has many problems. If the production scale is small, the efficacy is not as fast as chemical pesticides, and the investment required for the product mechanism, toxicology, and environmental behavior tests is high, and the research results show that there are many semi-finished products with prospects for application, and few can really develop into large ones; The product design and production technology provided by the scientific research unit is not mature enough or adequately supported. After the production, the enterprise will encounter many difficulties in production, quality, etc., and become obstacles to the development of biological pesticides; at the time of application, farmers lack the correct guidance, often Due to improper storage and missed drug use, the drug efficacy is affected. Compared with chemical pesticides, the price of biological pesticides is relatively high and consumer acceptance is difficult.

It is understood that insect virus insecticide has been widely used in the world, the United States, Britain, France, Russia, Brazil, Japan and India have a large number of applications. At present, more than 40 kinds of insect virus insecticides have been registered, produced and applied in the world. Yin Yinong suggested that relevant departments should increase investment in R&D, and in particular increase support for original biological pesticides. In addition, large-scale and targeted promotion of biopesticides should be carried out nationwide so that farmers can understand and master the insecticide mechanism and application skills of biopesticides.
