Causes and control techniques of bovine skin pathogen of Auricularia auricula

Pleurotus auricula is a disease that easily occurs in the process of planting Auricularia auricula, especially during mycelium growth or harvest, if brown and hard patches are found on the surface of the bag, the pathogen generally attacks. In this way, there will be no auricularia auricula, the phenomenon of reducing production, for growers, it is a great blow. Next, let's take a look at the causes and control techniques of the fungus.

1. The causes of the pathogen of Auricularia auricula cattle skin.

1. The fungus often appears in soil, cottonseed hull, sawdust or insects, so when the mycelium grows to the shoulder of the bag, the temperature in the bag is not well controlled. if it is relatively high, the miscellaneous bacteria will appear. Because this kind of miscellaneous bacteria can withstand high temperature, it will not kill it even if you disinfect it with high temperature.

2. The reason for the emergence of mixed bacteria of Auricularia auricula cattle may also be that the light is not well controlled. Because light inhibits the growth of Auricularia auricula. If the light is particularly strong during the cultivation of bacterial bags, the mycelium will appear black-spotted non-mycelium, showing a phenomenon of gelatinization. With the passage of time, there will be more and more spots, especially in the position where brown spots grow, so that the auricularia auricula fruit body can no longer grow.

Second, the control technology of Auricularia auricula cattle skin pathogen

1. Every production link needs to be strictly controlled

Because miscellaneous bacteria may occur at any period of the growth of Auricularia auricula, we should strictly follow every step of standardized production of Auricularia auricula, especially sterilization, vaccination and regular disinfection. If it is a strain carrying miscellaneous bacteria, it can not be used for production.

2. Attention should be paid to disinfection of perforation tools.

The occurrence of mixed bacteria of Auricularia auricula is likely to be the cross infection after the opening, because the disinfection of the opening tools is not in place. When opened to the bag infected by Alternaria solanacearum and continue to open other uninfected bags, it caused cross infection.

3. The difference between cowhide pathogen and mite infection of Auricularia auricula.

1. Color distinction

If Auricularia auricula is infected with cowhide bag, the color of the bag will change from yellow to dark brown and will not infect other miscellaneous bacteria.

If Auricularia auricula is infected with mites, the color will only be yellow, and it will be infected with other miscellaneous bacteria until it changes to sawdust color.

2. Distinguish from hardness

The place where the fungus is infected will slowly become solid and hard. It is easy to distinguish between the local bags infected by mites that slowly become soft and loose.

3. Shape to distinguish

If Auricularia auricula is infected with cowhide echinococcosis, it is flaky, and the miscellaneous bacteria grow from the point to the surface. If the mite is infected, it is multi-spot and multi-site growth.
