Experts pointed out that the soft rot of Pleurotus ostreatus is mainly manifested as the white mycelium of Pleurotus ostreatus is spider-like on the appearance of the trampoline, and it stretches rapidly, covering the bed surface and trapping around the seed body. The base of the seed body is affected by the hyphae, and the disease sensibly grows along the stipe. The bacteria initially reappears as a seed solid to prevent development, and the luster is dark, agile and soft, yellow, brown, and then erosion. Its prevention and control essentials: First, harsh treatment mushroom shed. Before the mushroom shed was opened, the king of mushrooms was sprayed. After two days of confinement, lime powder was sprinkled in the air at a rate of 250 grams per square meter. The second is spraying prevention in the era of germs. Every 5 days you spray 1 time Venus disinfectant 50 times, or bacteria kill 200 times and so on, pay attention to drugs do not spray directly on the mushroom bed or bag. The third is the harsh disposal of earth-covered materials. In the case of a mushroom wall or medlar type planting, special application of surface soil, vegetable garden soil, and soil extraction from the old mushroom area must be carried out with drugs for sterilization and insecticide disposal. Disposal method: First dry the soil, crush it, spray 60 times liquid of mushroom and 60 times phoxim and 600 times of phoxim, spray and mix while mixing. After mixing, cover the membrane and make stuffy stuffy. Open, can be applied after smell. Fourth, in the early stages of the disease, remove the cover soil together with the fabricated material and extend it by 10 cm to remove the pathogen and stop the spraying of water to the mushroom shed, and increase the amount of ventilation. If there is a precondition, only reduce the temperature of the shed. . Do not pay attention to other special circumstances, mushroom farmers do not arbitrarily string.

Pleurotus ostreatus atrophy, also known as damping-off disease, dry rot and so on. The pathogenic fungus was Fusarium mold, and the development of the diseased mushroom system stopped and the water-like atrophy was observed. The mushroom body was darkened and dried, and the lower tidal mushroom was difficult to produce. Its prevention and control essentials: First, the flat mushroom planted without covering the soil, stop contact with the soil, can reduce the incidence of disease. Second, the original disease area, should be treated with copper sulfate 180 times punishment mushroom shed, and at the same time to deal with occasions, to stop the bacteria spores into the material. The third is to maintain preventive medication in the era of germination and mushrooming. Fourth, in the early stages of the disease, the cover soil was excavated together with the 5 cm of the fabricated material, and was cleared out of the shed for disposal. Fifth, in the early and late stages of illness, the fruit of the ascarnate was removed and the material was excavated.
