Disease prevention and management of edible fungi should cut off the transmission route

November 21, 2021

The unique production methods of edible fungi and the different tissue structures of fruiting bodies that are different from those of higher plants require that producers not be able to spray chemical agents during the growth stage of fruiting bodies and must take “protection” first. The principle of "prevention as the mainstay and comprehensive prevention and control" was adopted to reduce the use of chemical pesticides, raise the level of product quality and safety, and adopt comprehensive prevention and control measures to control pests and diseases.

For the cultivation characteristics of edible fungi, the integrated pest control measures include:

Cut off the spread of pests and diseases

There are three sources of diseases and pests in the cultivation of edible fungi: one is that the strains carry insects, and the other is the source of the disease; the other is the culture material and the covering soil with insects and the source of the disease; and the third is the natural propagation inside and outside the mushroom house (shed). The cutting off of these three channels of communication is the most important issue for integrated pest management.

Environmental control to reduce pests and diseases

1. Reduce the temperature of the material: If the temperature of the Agaricus bisporus fungus material is controlled below 21°C, it can effectively prevent and control the P. fulvum; the temperature of the Flammulina velutipes is controlled below 20°C; the Pleurotus ostreatus bag can prevent bacteria bags from contaminating below 20°C. 2. Strengthen ventilation. Ventilation and ventilation is the best way to disinfect the air. Do not cause a stuffy environment. No ventilation can be harmful without any benefit. 3. Light adjustment. Different varieties have different illumination requirements. For example, the mushrooms should be darker, while the white mushrooms need to be stronger.

Agronomic control measures

Different soils have different microflora and different ecological environments have different biomes. Practice shows that the cultivation of soil sheds is generally good in the first year and worse in the second year. The reason is that the ecological environment of the shed is getting worse, which means that there are more bacteria, more pests, and the air quality is not good. To this end, we must improve the ecological conditions, optimize mushrooming environment, reduce and reduce the occurrence of pests and diseases.

Chemical control

Chemical control is generally used for preventive measures. It is forbidden to use chemical control during fruiting, because the tissue structure of the fruiting body is prone to produce toxic residues, affecting food and export. Therefore, it is forbidden to use medicinal control during fruiting. Even if it is absolutely necessary, it can only be sprayed before fruiting, and it is better to use phytochemicals, such as phytoalexin.
