White mold may occur during the whole growth of the potato. White mold mainly infects the stems and leaves of the potato, which causes the potato stems and leaves to rot. At the beginning of the disease, the leaves appear pale green. As the disease spreads, white mold spots grow gradually, and finally the potato stems and leaves rot. If not prevented in time, the disease will spread rapidly and bring economic losses to the farmers. In terms of the cause of the formation of potato white mold and the prevention and treatment methods, I hope that it will help everyone. First, the cause of the formation of potato white mold The disease is caused by potato planting soil pathogens by infecting the stems of the plants, especially in moist soil and air environment, breeding more serious. As the pathogen spreads along the stem with the stem and leaf, it spreads more rapidly in the middle and late stages of flowering (flowering to tuber enlargement). Second, potato white mold prevention and control measures 1, rim planting, more cultivation of strong seedlings, resistant seedlings It is best for the potato to be planted with grasses for 3-4 years, which will reduce the source of disease infestation. 2, enhance soil permeability, moisture and flood prevention During the potato planting process, water should be properly watered to improve soil permeability and reduce planting density. If potato plants are infected with white mold, it is necessary to remove the diseased plants in time to reduce the incidence of the second year. 3, late planting Potato planting should avoid early sowing, and late sowing can form resistant seedlings, which is beneficial to improve the disease resistance of plants. 4. Scientific and rational use of drugs Once the potato white mold disease is found, it is necessary to spray chemical agents in a timely manner. Chemical agents should choose a biocide with strong systemic absorption. The specific application method is: using 70% thiophanate-methyl WP, compound pyrazole Ethoxystrobin and tebuconazole, all field spray control.
