Abstract

The invention relates to the technical field of compounding of pesticides, and in particular relates to an antiviral composition containing glucosan. The antiviral composition comprises effective ingredients and auxiliary ingredients, wherein the effective ingredients are a component A and glucosan, the effective ingredients account for 1-80wt% of the antiviral composition, and the component A isa tetrahydro-beta-carboline alkaloid derivative. The antiviral composition is used for preventing and treating cruciferous vegetable virus diseases, or potato rugose mosaic, or camellia mosaic disease, or peanut stunt, or tomato virus disease or tomato gray mould. The antiviral composition provided by the invention has the advantages that the glucosan and the component A are taken as the effectiveingredients, control effect is improved, pesticide residue and environmental pollution are reduced, production of virus resistance can be beneficially avoided, and production speed of the virus resistance is slowed down.

Description

technical field [0001] The invention relates to the technical field of pesticide compounding, in particular to an antiviral composition containing dextran. Background technique [0002] Plant viral diseases pose a serious threat to crop yield and quality worldwide, causing 10-30% yield reduction and economic losses of about 20 billion U.S. dollars every year. It is widely distributed, various in variety, wide in transmission route and serious in harm. The prevention and control methods of plant virus diseases mainly include: 1) Breeding disease-resistant varieties, detoxification of seeds or vegetative bodies, using attenuated strains and satellite RNA; 2) Killing and killing biological virus transmission mediators; system, etc.; 4) chemical agent control. The comprehensive control measures centered on the promotion of disease-resistant varieties are just a preventive measure, and there are no ideal disease-resistant varieties at present. The lack of effective control agen...
