Prevention and Control of Edible Bacterial Spot Disease
Bacterial spot disease, also known as bacterial brown spot, is a major hazard to mushrooms and flat mushrooms. The disease is confined to the cap of the sclerotium. The water spots on the sclerotium begin to appear as small spots, gradually turning yellow-brown and expanding into small spots. Irregular, viscous bacilli in the pits. When the spots are dry, the caps are covered. Often cracking. The soil and culture materials are the main sources of primary infection. The mushroom caps may be infected when the mushroom bulbs pass through the soil. If the watering of the mushrooms is improper, the bacteria on the bacteria bed may splash on the caps of the bacteria. First infestation. The prevention and control of the disease should be based on ecological control. During the fruiting period, the wet and dry environment outside the bed of bacteria should be created. This will help to stimulate mushroom production. It will not only ensure the need for humidity during the fruiting period, but also inhibit the occurrence of the disease. Try to water in the morning and evening as soon as possible to avoid hot air entering the mushroom house, causing the bacteria to condense, and spray water droplets to be fine. After spraying, immediately ventilate for 30-60 minutes to make the mushroom surface dry as soon as possible, and the infection is more difficult to occur. . Avoid watering and ventilation when the temperature is high at noon, and remove the mushrooms as soon as possible for the diseased mushroom house. Pay attention to the operation so as not to cause artificial spread. After removal of the mushroom, the mushroom house should appropriately reduce the number of water sprays and the amount of water spray until the mushroom does not appear again. In addition, spraying 600 times of sodium hypochlorite on the mushroom bed is better.
