Method for preventing and treating lentil mosaic virus disease

Control methods: (1) Select the varieties with strong disease resistance such as white flower noodles (Emei bean) and safflower noodles (red side Emei beans). (2) Establish disease-free seeding fields, remove diseased plants in time, and select seeds that are truly disease-free and have no brown spotted beans. The above three viruses have different degrees of seed transmission, of which SMV can reach 30%. (3) Strengthen the management of fertilizer and water and improve the disease resistance of plants. (4) Control mites early to prevent the spread of the virus. (5) If necessary, spray 7.5% of bactericidal morpholine (Keulinling) water 700 times solution or 3.85% ribavirin · copper · zinc (virus gram) at the beginning of the disease Wettable powder 600 times liquid or 25% morpholinium·zinc (virtual killing) soluble powder 500 times liquid, 0.5% mushroom proteoglycan water 300 times liquid, once every 10 days, depending on the disease prevention and treatment 1 Times or 2 times.
