Disease Control of Mushroom in Summer

According to the characteristics of high temperature, high humidity and high base number of miscellaneous bacteria in summer, effective control measures should be taken to ensure the smooth progress of production.

1. Disease prevention measures at the stage of growing bacteria.

Due to the influence of high humidity, the success rate of cultivation is greatly reduced, which is mainly manifested as slow bacteria, weak hyphae, high contamination rate and so on. Main measures:

1. Strain detoxification, deployment of base materials: virus-free bacteria can ensure that they do not carry virus bacteria, and effectively improve resistance, which is the basis of production. The study shows that every 250 kg of cottonseed shell raw material, adding 50 grams of edible fungus three-dimensional nutrient essence (mixing type) can obtain many effects, such as exuberant mycelium, improved resistance, accelerated growth, greatly reduced pollution rate and morbidity and so on.

two。 Strict cultivation and disinfection. Thorough disinfection and sterilization in the culture shed is one of the important conditions for successful sterilization. In the production, spraying all kinds of diseases in the culture room (shed) can be used after 2 days of airtightness, and it is an effective preventive measure to spray Sabai 09 medicine or mushroom to kill the disease every 5 days or so during the period of bacteria infection.

3. Keep ventilating and dehumidifying. On the one hand, adhere to the sunny night and morning ventilation to make the air fresh; on the other hand, put raw lime in the culture room (shed) to make it wet. However, it should be noted that under the condition of cooling without air conditioning, measures such as forced ventilation and careful management should be taken to ensure the success of bacteria transmission.

II. Prevention and control measures at the stage of mushroom emergence

Practice has proved that the prevention and control effect of twice the result with half the effort can be achieved by changing the traditional concept of "treatment" rather than "prevention" and adhering to the principle of "giving priority to prevention and paying equal attention to prevention". The following measures can be taken for reference in production:

1. Eliminate virus inside and outside the mushroom shed. On the basis of cleaning and sanitation, 800 times carbendazim solution was sprayed outside the shed, and carpet spraying was carried out in the shed without trace of all diseases or Sebe09, the environment was poor, the old cultivation shed could be sprayed twice, and it could be used after 2 days of exposure.

two。 The addition of Sebe09 medicine to the mixture has good bactericidal effect and low drug residue, which can effectively reduce the contamination rate of bacteria.

3. Regular use of drugs during mushroom emergence to maintain a good environment. Generally, Saibai 09 medicine can be used to spray the mushroom shed, and those with poor environment can be sprayed once every 5 days to inhibit or kill later pathogens, so as to keep the environment relatively clean.

4. It was found that the disease was completely wiped out. The matching use of the above measures, in today's deteriorating environment, it is still difficult to guarantee 100% disease-free. Therefore, attention should be paid to observation in production, that is, when signs of bacteria are found in the bacterial bag, drugs such as Xiaomiwang should be used to kill the affected area, and Seb09 immersion bag can also be used; when the fruiting body has the first disease, drugs should be used according to the disease performance or the variety of pathogens, and avoid "emergency and random treatment".
