What symptom does black fungus get green mildew to have? What are the prevention and control measures?

Auricularia auricula is one of the fungi that we often eat in our life. Because Auricularia auricula is mycelium, it is very likely to be infected by insect pests and miscellaneous bacteria when cultivated. Once we get sick, it will cause great losses to our growers, and some of them even lose all their money, which no one wants to see. Green mold of Auricularia auricula is a common disease, so what are the main symptoms? What are the prevention and control measures?

One, what symptom does black fungus get green mold to have?

Green mold of Auricularia auricula is a kind of disease which is very easy to appear in the process of cultivation of Auricularia auricula. There are many kinds of green fungus, mainly green Trichoderma, green fungus and deep green Trichoderma. In any period of the growth of Auricularia auricula, it is possible to be infected with green mold. If infected with the pathogen, the fungus will appear white hyphae on the initial fruiting body, which is relatively slender. Powdery green mold appears after the spores are multiplied in large numbers.

Generally speaking, no matter the medium or fruiting body, or sawdust, it is possible to cause colonies. Especially after ear picking, the ear root is also easy to be infected, because the fungus is easy to occur under the conditions of high temperature, relatively high humidity and acidic culture material.

The main harm of green mold is mainly in three aspects: the first is to snatch nutrients from the mycelium after decomposing cellulose and lignin in the culture medium; the second is to secrete certain toxins to affect the growth of Auricularia auricula hyphae; the third is to produce spores to pollute the environment of cultivating Auricularia auricula and increase the difficulty of mycelium culture.

Second, how to distinguish green mold of black fungus?

Fungus green mold is very easy to distinguish, first of all, if infected with this bacteria, the bag will turn green, the green spores of green mold will also be seen in the culture medium, and the distribution is not into pieces, its hyphae are thinner than the mycelium of Auricularia auricula. Then the green mold smells like a mixture of moldy clothes and rotten wood, especially when the bacteria multiply in large numbers, and experienced growers can judge whether they have green mold by smelling it. Finally, it can also be felt by touch, because with the passage of time, the culture medium of the fungus bag slowly softens, and if it feels that the fungus bag is not soft, it may be the emergence of green mold.

Third, what are the prevention and control measures for green mold of black fungus?

1. Pay attention to the cleaning of the cultivation environment of Auricularia auricula, do some cleaning work, and reduce the existence of miscellaneous bacteria.

2. Pay attention to the ventilation of the Auricularia auricula cultivation room, so that it will not be too wet and increase the chances of bacteria proliferation.

3. After the fungus comes out, a certain concentration of lime water should be sprayed every day, which can have a good anti-mildew effect.

To sum up, if Auricularia auricula is not suffering from green mold, it is necessary to destroy the favorable environment for the occurrence of mold, so every step of the cleaning and disinfection must be done strictly.
