2, the cause of the disease. Pleurotus ostreatus pathogen is Pseudomonas. 1 The fungus is suitable for use on substrates with a moist environment and rich organic matter. Under conditions of high temperature, high humidity and poor ventilation, it is beneficial to the occurrence and growth of the bacteria. 2 The environment of the old cultivation site has deteriorated and disinfection has not been thorough. 3 In the shed, waste culture materials, miscellaneous mushrooms, and mushroom stalks are everywhere, and the filth has caused the bacteria to inhabit and reproduce. 4 Now the cultivation of oyster mushrooms is mainly based on raw materials or fermentation materials, and the cultivation materials themselves carry bacteria to cause the disease. 5 use of water or earth-covered material with bacteria. The poor resistance of the 6 strains or the poor quality of the strains, as well as the poor management of the cultivated households, led to slimmer mycelium in the cultivation bags, reduced resistance, and eventually led to the onset of infectious bacteria. 3, preventive measures. (1) Strains that are adapted to the local environment and have strong disease resistance, such as Heiping Wang, Huiping Disease-resistant No. 2 and P89, are generally not susceptible to the onset or lighter incidence. The same site should not be planted with the same strain for successive years, and it is advisable to replace the variety with 2 to 3 years. 2 to use non-bacterial contamination. Mycelium thick white, stout, age-appropriate species. 3 Select high-quality raw and auxiliary materials that are free from mold, worms, and pollution. Before the culture materials are used, they must be exposed to sunlight. Add bactericidal drugs such as Keshiwang or carbendazim with a dry weight of 0.1%. 4 The old site should not be used year after year. If it is used, it must be sterilized and pesticidal treatment one month before the cultivation bag enters the shed. The fungicide can be used 500 times of carbendazim, 500 times of benzene bacteria, etc., and 200 times of bleaching powder can be used for killing bacteria. Liquid, agricultural streptomycin 500 times, Wan Xiaoling 2000 times and so on, the insecticidal 500 times liquid of dichlorvos and 1000 times of high efficiency cypermethrin can be sprayed on the ground, walls and shed environment in the shed once a week. 2 to 3 days before entering the shed, then fumigated with sulphur for 24 hours. 5 Strengthen the cultivation period of the cultivation bag to improve the ability of the mycelium to resist disease and resist miscellaneous diseases. During the fruiting period, it is necessary to control the temperature and humidity in the shed. Excessive temperature is unfavorable to the growth of general wide-temperature or low-temperature strains. Instead, it provides a suitable temperature environment for various bacteria and bacteria; The growth is favorable and it is also suitable for the growth of various bacteria. 6 The mushroom shed should be built in a well-ventilated place with convenient drainage. The ventilation in the shed should be smooth. The setting of the ventilation openings should be suitable for the flow of wind at each material surface. There should be no ventilation dead angle, according to temperature, weather, and wind speed. Factors such as timely adjustment of ventilation time. 7 When using cover soil cultivation, the earth-covered material shall be sterilized and killed. 8 Do a good job of environmental sanitation in the shed. Remove mushrooms after the mushrooms are harvested, keep the ground clean, and regularly disinfect the lime powder to disinfect the environment.

Occurrence and Control of Pleurotus ostreatus Mushroom Disease
1, the symptoms. Mushroom disease mostly occurs from the young mushroom mushroom cover or the mushroom mushroom handle and the mushroom cap joint. After the onset of the disease, the young mushroom mushroom cover or the small mushroom mushroom cover recess appears yellowish patches, and the young mushroom mushroom body is sticky and stops growing. Death, mushroom body slow growth, loss of elasticity, a little touch will be broken, then the mushroom body sticky atrophy, emit a rancid odor, the rapid spread of the disease, will lead to sticky material and stop mushrooming.
