Control techniques of Trichoderma volvacea

Straw mushroom, also known as orchid mushroom, is mainly distributed in South China, its nutrition is rich, delicious, is one of the common dishes, and now there are more straw mushrooms. Trichoderma is a very harmful disease in straw mushroom planting, which seriously affects the yield and quality of straw mushroom, so how to control Trichoderma volvacea? Let's get to know it.

1. Symptoms

Straw mushroom will grow white cotton wool after being infected with Trichoderma, which will inhibit the growth of mycelium, and in the later stage, white cotton will turn green. Once straw mushroom is harmed by Trichoderma, it is basically saved. If only a mild infection cannot be retained, it must be removed immediately.

2. The regularity of the disease

Trichoderma, commonly known as Chlorophora, belongs to the subphylum Trichoderma, Trichoderma. It has a strong ability to decompose cellulose and grows rapidly on the substrate of lignin and cellulose. it is easier to reproduce Trichoderma in the rhizosphere at noon by occupying space and nutrition to control harmful fungi. It can also increase the secretion of antibiotics to inhibit the proliferation of harmful fungi to achieve the effect of disease control.

3. prevention and control measures

So far, there is no way to cure volvariella volvacea Trichoderma, commonly used fungicides can only play an inhibitory role, there is no possibility to kill it, even if the agent is increased, it will only kill the straw mushroom hyphae. Therefore, prevention is given priority to, the mycelium of straw mushroom grows in a relatively good environment, and this environment is not suitable for the growth of Trichoderma, so it is the fundamental measure to control straw mushroom infection with Trichoderma. After it is found that there is straw mushroom infection, it is necessary to reduce the temperature of the mushroom room in time and maintain ventilation, which can effectively control Trichoderma. If you are infected with Trichoderma at the time of infection, you can take the method of injecting liquid to inhibit the expansion of Trichoderma. The commonly used agents are 5% carbendazim, 2% formaldehyde, 50% carbendazim, 100% thiophanate methyl, etc., or spread a layer of lime to control its spread.

The above is the introduction of straw mushroom Trichoderma control technology, hope to help you, want to know more related knowledge, please pay attention to us.
