Abstract

The invention brings forward a prevention and treatment method for tobacco mosaic virus disease, reducing the morbidity of tobacco mosaic virus disease, increasing the production and grade of tobacco. The prevention and treatment method comprises following steps: 1. agricultural prevention and treatment; 2. biological prevention and treatment: spraying an antiviral agent 500 times solution; 3. physical prevention and treatment: keeping clean of the field, clearing up infected plant or weed and destroying them centrally; 4. chemical prevention and treatment: spraying 20% moroxydine copper acetate wettable powder 1000 times solution before morbidity. The method employs biological agent such as 0.5% lentinan AS 500 times solution; antiviral agents such as 20% moroxydine copper acetate wettable powder 1000 times solution are sprayed before morbidity to exterminate tobacco mosaic virus. Field tests have shown that by use of the integrated prevention and treatment method including agricultural and physical prevention and treatment, tobacco mosaic virus disease can be prevented, the average morbidity of tobacco mosaic virus disease is decreased, tobacco production and grade are increased, and economic benefit is achieved.

Description

technical field [0001] The invention belongs to the field of tobacco disease prevention and treatment, and in particular relates to a method for prevention and treatment of common tobacco mosaic disease. Background technique [0002] Tobacco, Latin scientific name: Nicotianatabacum, is an important economic crop. Tobacco is an annual herbaceous plant in the family Solanaceae, and there are about 60 species of Nicotiana. Tobacco mosaic (Tobacco mosaic) is a kind of "terminal disease" commonly known as tobacco cultivars that commonly occurs in various smoking areas in the world. x 18 nm. TMV overwinters on diseased plant residues, tobacco stalks, tobacco branches, shredded tobacco leaves, other host plants and weeds. TMV is easily transmitted through contact, can occur in both seedbeds and fields, and is easily spread through leaf cutting and field operations. . The sources of initial infection of seedbeds are mainly fertilizers with diseased plant residues, diseased resid...
