Abstract

The invention relates to an integrated control method of tobacco viruses. The integrated control method is characterized in that the method integrates agricultural control, physical control, biological control, chemical control and the like; before seedling culture, methyl bromide and 98% dazomet granules are used as the sterilizing agents to sterilize a seedbed, and sanitation and hygiene management is performed during seedbed maintenance; rotten substances around the seedbed is cleaned, maintenance staff need to pay attention to personal hygiene, smoking is prohibited, seedlings cannot be placed overnight during transplanting, a seedling plating site needs to keep clean and sanitary, and the seedlings lifted from a nursery garden is immediately transplanted to a field; reasonable balanced fertilization management is performed after the transplanting, the zinc element chelate state is timely supplemented after the transplanting, applying 0.5% lentinan aqueous solution and the 1500 times liquid of nano mesh-structured pesticides after the seedling transplanting, and applying 20% moroxydine hydrochloride cupric acetate wettable powder, the 1500 times liquid of nano mesh-structured pesticides and 3.6% sodium silicomolybdicate. Tests show that when the method is applied to a tobacco field of 1 mu to control the viruses, the incidence rate of the tobacco viruses is 0.25-0.4%.

Description

technical field [0001] The invention relates to the technical field, in particular to a method for comprehensive prevention and treatment of tobacco virus. Background technique [0002] Tobacco virus disease, commonly known as tobacco mosaic disease, is the most widely distributed and most common disease in tobacco production. At present, 16 kinds of tobacco virus diseases have been discovered in my country, among which the viruses that cause tobacco mosaic disease mainly include TMV, CMV, and PVY. Viral diseases in most areas are mixed with several viral diseases such as tobacco cucumber mosaic virus (CMV) and tobacco common mosaic virus (TMV), and repeated infection (such as Shandong, Henan, etc.). The rate of diseased plants in the field is generally 20% to 40%, and 40% to 80% in severe cases (as high as 100% in some local plots). After the tobacco is infected with the virus, the chlorophyll is destroyed, the photosynthesis is weakened, the growth of the leaves is inhib...
