Method for preventing and curing plant disease by increasing plant immunity and use thereof

Abstract

The invention provides a plant protective method and application of inducing immune system of plant by 4-methyl-1,2,3-thiadiazolyl-5-formic acid (NK-F001), sodium 4-methyl-1,2,3-thiadiazolyl-5-formate (NK-F002), 4-methyl-1,2,3-thiadiazolyl-5-ethyl formate (NK-F003) and methenaimde (SZG-7) to generate resistance against the plant virus. The invention also provides an application for improving the plant immunity by combination of two or three of 4-methyl-1,2,3-thiadiazolyl-5-formic acid (NK-F001), sodium 4-methyl-1,2,3-thiadiazolyl-5-formate (NK-F002), 4-methyl-1,2,3-thiadiazolyl-5-ethyl formate (NK-F003), methenaimde (SZG-7), benzthiadiazole (activated ester, BTH), tiadinil (TDL), DL-Beta-aminobutyric acid, virazole, ningnanmycin, antofine, Bingduxing No.1, Bingduxing No.2, XY-13 and XY-30 so as to induce the plant to generate antiviral activity, processing dosage forms of single and mixture preparations, and compositions and contents of effective components in the dosage forms. The invention discloses a plant inducing range and plant antiviral inducing range of compounds and compositions thereof, and application of plant protection in the fields of agriculture and horticulture thereof.

Description

technical field [0001] The technical scheme of the invention relates to a method for improving plant immunity by using chemically synthesized compounds, and the use of these compounds for improving the resistance of agricultural plants and horticultural plants to infection by virus diseases. Background technique [0002] Plant virus disease is the "cancer" of plants, and its prevention and control methods mainly include physical methods and chemical methods-mechanical methods, but each method can not achieve the desired effect. In chemical methods, there is currently no one that is completely effective. Agents that can control plant virus diseases. Since the occurrence of viral diseases is closely related to the host plant, it has always been the ideal and direction of efforts for agricultural scientists to explore the mechanism of plant resistance to prevent and control viral diseases. , the plant activator is the outstanding achievement of research in this direction.

[0002] Plant virus disease is the "cancer" of plants, and its prevention and control methods mainly include physical methods and chemical methods-mechanical methods, but each method can not achieve the desired effect. In chemical methods, there is currently no one that is completely effective. Agents that can control plant virus diseases. Since the occurrence of viral diseases is closely related to the host plant, it has always been the ideal and direction of efforts for agricultural scientists to explore the mechanism of plant resistance to prevent and control viral diseases. , the plant activator is the outstanding achievement of research in this direction. It can also avoid the adverse effects of traditional pesticides on beneficial organisms by directly acting on pests, weeds and pathogens to achieve the purpose of insect control, weed control and disease prevention. And to the pressure of environment, at present the plant activator BTH that develops most successfully has been used widely in the world (Bakulev V A, Dehaen W.The Chemistry of 1,2,3-thiadiazole, 2004, John Wiley & Sons, Inc.) , the inventor started from basic research and was funded by the National Natural Science Foundation of China (30270883 and 20672062), the "973" Program (2003CB114402), the Tianjin Natural Science Foundation (07JCYBJC01200) and the Tianjin Science and Technology Support Program International Science and Technology Cooperation Project (07ZCGHHZ01400) Under the design, synthesis and discovery of N-(5-methyl-1,3-thiazol-2-yl)-4-methyl-1,2,3-thiadiazole-5-carboxamide (hereinafter referred to as thiadiazole-5-carboxamide) ) has good biological activity (Fan Zhijin et al., novel [1,2,3] thiadiazole derivatives and their synthesis method and application, National Invention Patent of the People’s Republic of China, Publication No.: CN1810808A; Fan Zhijin et al., have induced gold wire A new compound with secondary metabolic activity of plants of the genus Peach, National Invention Patent of the People's Republic of China, Publication No.: CN2020667A); Afterwards, the inventor carried out systematic structure optimization and creation research on this type of compound (Fan Zhijin, etc., Thiadiazole Formamide derivatives and their synthesis methods and uses, National Invention Patent of the People's Republic of China, application number: 200810052546.6; No.: 200810052547.0; Fan Zhijin, et al., Thiadiazole imine derivatives and their synthesis methods and uses, National Invention Patent of the People's Republic of China, application number: 200810052553.6)
