New pesticides: activate plant autoimmunity
Plant virus disease is a kind of disease that is harmful and difficult to control. It is also called plant "cancer". Traditional antiviral agents mostly passivate viruses that invade plant cells, inhibiting their ability to interfere with plant cells, but the duration of the drug is short and the efficacy is not stable. With the continuous advancement of research and development in the pesticide industry, scientists and technicians have found another class of agents with different mechanisms of action, which can more effectively prevent and control viral diseases by stimulating the immune function of plants themselves. The application of such plant immunity to pesticides has become a highlight of green prevention and control of pests and diseases. Let's take a look at what is unique about these new types of viral disease prevention and control pesticides. Toxic fluorophosphate Recently, the project "Development and Application of New Crops for Control of Crop Virus Diseases and Vector Insects" won the second prize of National Science and Technology Progress Award. This project has innovated a new structure of anti-plant virus biomimetic new pesticide, toxic fluoride, with independent intellectual property rights. The patent of toxic fluorophosphate belongs to Guangxi Rural Biochemical Co., Ltd., and the chairman of the company, Li Weiguo, introduced that toxic fluorophosphorus is the first synthetic new compound in the world. It has a long-lasting effect of 10~15 days and has strong internal absorption. The action can be quickly transmitted to various parts of the plant through the absorption of crop leaves, destroying the outer shell of the virus, making the virus fixed and unable to continue to proliferate, effectively preventing the further spread of the disease. It is understood that the mechanism of action of toxic fluorophosphate is unique. It can activate the salicylic acid signal molecules to activate downstream PAL, POD, SOD and other plant defense factors, improve the overall system disease resistance of the crop, and ultimately prevent the virus from proliferating. Not only active defense, but also promote growth, by regulating plant endogenous growth factors, promote root growth, restore leaf function, and reduce yield loss. Because toxic fluorophosphate is a compound synthesized by the phosphoramidate in the rumen of sheep, it is highly safe for crops and highly safe for non-target organisms such as bees, silkworms, fish and birds. It can be used on crops such as rice and tomatoes. application. On the basis of the successful development of toxic fluorophosphorus, a new strategy of whole-line immune prevention and control of rice virus disease was proposed, and a new technical system of "controlling insects and preventing disease" was constructed, which solved the major problems of crop virus disease and vector insect prevention and control. Up to now, the project has applied a total of 47.55 million mu in the country, creating economic benefits of 4.845 billion yuan, 23 national invention patents, 7 national new pesticide registrations, and 2 national key new products. Emodin methyl ether At this year's National Science and Technology Awards Conference, the project “Creation and Application of New Natural Germanium Compound Agricultural Fungicides†was also awarded the second prize of National Science and Technology Progress Award. It is understood that the new natural bismuth compound is derived from the secondary metabolite of natural plant sources, called emodin methyl ether. The emodin-derived plant-derived fungicide not only directly inhibits the growth of plant pathogenic bacteria, but also activates the active immune system of the plant, inhibits the formation of pathogenic bacteria, protects the crop from pathogenic bacteria, and achieves the effect of disease prevention, and has a plant disease-inducing agent. Typical features. Moreover, the synergistic bactericidal action between the terpenoids was carried out. After 8 hours of spraying emodin methyl ether, the expression of antibacterial thiopurine protein in the treated part of the crop was significantly improved, and the mechanism of action was very unique. Compared with chemical pesticides, emodin has low risk of drug resistance, high activity and low dosage. The active ingredient per acre is only 0.15~0.30g, the disease prevention effect is good and stable, and the sterilization spectrum is wide. For powdery mildew and rice blast More than 10 important pathogens such as bacteria, Rhizoctonia, Sclerotinia, Fusarium, and Anthrax have bactericidal activity. Low toxicity, rapid degradation, half-life of digestion in soil is 2.8 days, low residue, basically no application interval, is an ideal substitute for chemical fungicides, especially suitable for green and organic vegetable production, has been obtained EU ECO- CERT organic certification. Inner Mongolia Qingyuanbao Biotechnology Co., Ltd. is the first and exclusive unit to obtain the official registration certificate of emodin methyl ether pesticide. In recent years, the company has invested more than 60 million yuan in Wulanbu and ecological management areas in Inner Mongolia to build plant-derived pesticide raw materials. The production base and the production line of emodin methyl ether plant source fungicide with an annual production capacity of 1,000 tons. Accumulatively promoted the use of 21,166,700 mu, and recovered more than 3.6 billion yuan of disease losses. The cost per unit of medicine, labor and pesticides per mu was more than 700 million yuan. Because emodin methyl ether is based on rhododendrons such as rhubarb, the raw materials can be planted in deserts and barren land, which also provides a new way for farmers to get rich. Oligosaccharide-chain protein Aiming at the occurrence characteristics of plant virus disease and the mechanism of plant resistance, a new type of protein bio-pesticide scientifically compatible with plant immune-inducing protein and amino oligosaccharide has attracted wide attention in the industry, which is also the world's first protein bio-pesticide. The plant immune-inducing protein is a novel protein pesticide extracted by fermentation of Alternaria alternata. Plant virus parasitization, which proliferates in plants, causes abnormal growth of plants or yellowing of leaves. It is difficult for chemical drugs to destroy the structure of virions, and protein biopesticides can solve this problem well. When exposed to the surface of plants, plant immune-inducing proteins can bind to receptor proteins on plant cell membranes, causing a series of related enzyme activities in plants, activating plant resistance systems and improving their disease resistance. Researchers have screened a large number of weak pathogenic pathogenic fungi, obtained a strain of Alternaria alternata that can effectively improve plant immunity, isolated and purified high-activity heat-stable protein, through high-efficiency protein production and processing technology, and added synergistic factor amino oligosaccharide It is formulated into a 6% oligosaccharide-chain protein wettable powder. Its unique mode of action not only inhibits the gene expression of the virus in the crop, but also controls its reproduction. It can also repair the damage of the damaged plant through cell activation and systematically control the virus disease. At the same time, it can stimulate gene expression in plants, and produce chitinase with anti-disease effect, induce plants to produce multiple defense responses, improve their disease resistance, and play a role in disease resistance and insect resistance. The 6% oligosaccharide-chain protein wettable powder can be soaked, seeded and coated to increase the germination rate of the seed and make the seedling grow robust. It can be diluted 1000 times for foliar spray, and can also be applied by flushing, hole application and irrigation. After experimentation and promotion, the effect of preventing and treating viral diseases on tomatoes, tobacco and other crops is very prominent. Since its launch in June 2014, it has achieved sales exceeding 50 tons and the application area is 1 million mu.
