How to control diseases and insect pests of Pleurotus ostreatus?

Pleurotus ostreatus is a kind of mushroom with white color, thick cap and thick stalk. It is also a common edible fungus in daily life. Pleurotus ostreatus can not only eat fresh, but also can be processed into canned food, which has a certain nutritional value. In the process of planting Pleurotus ostreatus, it is very vulnerable to diseases. Let's take a look at how to control the occurrence of diseases and insect pests of Pleurotus ostreatus.

First, how to control diseases and insect pests of Pleurotus ostreatus?

Diseases of Pleurotus ostreatus are most likely to occur in high temperature weather, such as walnut fleshy bacteria, jumping insects, mushroom mosquitoes, mites and so on. If attacked by these diseases during the germicidal period, edible chemicals can be mixed with materials for sterilization and insecticidal treatment.

1. Disease treatment methods: because the pathogenic spores of walnut fleshy bacteria mainly appear from the soil, if you want to control the disease, we should first start with the material covered with soil. Do not use the pastoral soil of discarded mushroom material, but choose the clean middle soil dug out from the paddy field, smash it and then dry it. It should be treated with the relevant medicine a week before eating.

During the mushroom emergence period, if there are irregular clumps on the soil surface, or if there is a decrease in the surrounding mushrooms, the soil should be removed immediately to check whether the culture material is contaminated by miscellaneous bacteria. If the culture material has a peculiar smell and discoloration, the bacteria may appear.

2. The treatment of insect pests: after covering the soil, you can spray an appropriate amount of mushroom water, and then add some chemicals to the water to control the insect pests in the mushroom stage, the main insecticides are mushroom insect insecticides. When the temperature rises above 20 degrees Celsius and there is mosquito activity on the mushroom bed, cypermethrin should be used to kill insects. Spray properly around the mushroom bed, on the ground and on the wall, so that it can kill insects effectively.

II. Key points of management of Pleurotus ostreatus in winter and spring

1. management before the beginning of winter

When the mycelium of Pleurotus ostreatus grows to half of the soil layer in a large area, it is necessary to maintain the soil moisture and not be too dry. When the buds are the size of rice grains, you can spray a little water to make the soil surface bright, but no water seeps down, wait ten minutes and cover the grass curtain.

In daily management, spray more on sunny days, less on rainy days, less on mushrooms, and more on more mushrooms. Do not spray the mushroom bud directly when spraying water. It is not recommended to spray water at noon when the temperature is too high.

2. Winter management

When the temperature drops to a certain temperature, the mycelium stops growing, so it is necessary to cover the agricultural film and then compact it with clods. Ventilation measures must be taken at noon on a sunny day. If there is no ventilation for a long time, it is easy to cause diseases and insect pests.

3. Spring management

The temperature begins to pick up in spring, so you can use a certain concentration of urea to soften the soil layer, so that the mycelium growth can be delayed a little bit. It can be less ventilated during the day and more ventilated at night in spring.
