How to use environment to control edible fungus diseases and insect pests.

Environmental control to reduce the occurrence of diseases and insect pests of edible fungi.

1. Reduce the material temperature: if the material temperature of Pleurotus ostreatus is controlled below 21 ℃, walnut fleshy bacteria can be effectively controlled, the temperature of Flammulina velutipes is below 20 ℃, and the bag pollution of Pleurotus ostreatus can be prevented under 20 ℃.

two。 Strengthen ventilation and ventilation. Ventilation is the best way to disinfect the air. Do not create a stuffy mushroom environment. Not ventilating will do more harm than good.

3. Light adjustment. Different varieties have different illuminance requirements. For example, Pleurotus ostreatus should be darker, while Pleurotus ostreatus should be stronger.

1. Cut off the transmission of diseases and insect pests

There are three sources of diseases and insect pests in edible mushroom cultivation: first, bacteria carry insects, with disease sources; second, culture materials and covered soil carry insects and disease sources; third, natural transmission inside and outside mushroom houses (sheds). Cutting off these three transmission channels is the top priority of integrated pest control.

Second, environmental control to reduce the occurrence of diseases and insect pests

The main results are as follows: 1. Reducing the material temperature: if the material temperature of Pleurotus ostreatus is below 21 ℃, it can effectively control walnut fleshy bacteria, the temperature of Flammulina velutipes is below 20 ℃, and the bag pollution of Pleurotus ostreatus under 20 ℃ can be prevented.

2. Strengthen ventilation and ventilation: ventilation is the best way to disinfect the air. Do not create a stuffy mushroom environment. Lack of ventilation will do more harm than good.

3. Light regulation: different varieties have different illuminance requirements. For example, Pleurotus ostreatus should be darker, while Pleurotus ostreatus should be stronger.

III. Agronomic control measures

Different soils have different microflora; different ecological environments have different biological communities. Practice shows that the cultivation of soil shed is generally good in the first year and poor in two years, and the reason is that the ecological environment of the soil shed is getting worse and worse, that is to say, there are more germs, more insect pests, and poor air quality. For this reason, we must improve the ecological conditions, optimize the mushroom environment, reduce and reduce the occurrence of diseases and insect pests.

IV. Chemical control measures

Chemical control is generally used as a preventive measure, and the use of chemical control is prohibited during mushroom production, as the tissue structure of the fruiting body is prone to residual poison, affecting food and export. Therefore, the use of chemical control is prohibited during mushroom production, even if it has to be used, it can only be sprayed before mushroom production, and it is best to use plant preparations, matrine and so on. If it needs to be specially mentioned, the use of highly toxic and high residual pesticides is absolutely prohibited.
