What are the common pest and disease control methods for wood ear mushrooms?
Wood ear mushrooms are a common delicacy in our lives. They are delicious, nutritious, and can be eaten in many ways, making them a favorite food. Wood ear mushrooms are developed from fungal spawn, but during cultivation they can also be harmed by other pathogens and insects. So how should these pests and diseases be controlled? Below, Qinongwang explains the control methods for several relatively common pests and diseases. Let's take a look.
1. Green mold disease of black wood ear mushroom
When fungus bags or log sections are inoculated, they become infected with green mold. In the early stage of the disease, white mycelium appears on the culture material or fruiting bodies, looking very much like the mycelium of wood ear mushrooms. The mycelium grows extremely fast, and after a few days it can form conidia. Once the spores begin to form and mature in large numbers, the colony turns into a green powdery substance, which is also the origin of its name.
Control methods: Pay attention to the hygiene of the cultivation site and its surroundings, keep the planting site well ventilated and easy to drain, and disinfect when entering and leaving the culture room to prevent pathogens from being brought in. After the wood ear mushrooms emerge, spray 1% lime water every day. Before the disease has fully broken out, you can also scrub the affected areas with a higher concentration of lime water, which can inhibit growth.
2. Flowing ear
Flowing ear occurs in the late stage of fruiting. When the ear pieces are about to mature or have already matured, the ear pieces begin to soften and even rot. It is a symptom of wood ear mushroom cell rupture. When the ear pieces mature, they continuously produce spores, consuming a large amount of nutrients from the fruiting body and causing the fruiting body to age. At this time, if the environment is high in temperature and humidity, flowing ear is likely to occur. In addition, bacterial infection and pest damage can also cause flowing ear in wood ear mushrooms.
Control methods: Strengthen management, pay attention to ventilation and light conditions, and harvest in time. Harvesting promptly when the wood ear mushrooms are about to mature or have already matured can avoid this problem. A oxytetracycline solution spray can be used to prevent flowing ear.
3. Thrips
Thrips are also called climbing pole insects. As adults they are relatively small and black in appearance, and are not easy to find in dimly lit environments. Their larvae begin to harm wood ear mushrooms, invading the ear pieces and sucking sap, causing the ear pieces to shrink. In mild cases this reduces yield, and in severe cases it causes flowing ear and total crop failure.
Control methods: Pay attention to environmental hygiene, promptly clean up fertilizers and contaminated bags, spread a layer of lime powder on the ground once to eliminate overwintering pest sources, and install window and door screens in the spawn-running room to prevent insects from entering. When pest damage occurs, sugar-vinegar liquid can be used for trapping and killing, or trichlorfon solution can be sprayed to kill the pests and eliminate the damage.
The above are the common pest and disease control methods for wood ear mushrooms brought to you by Qinongwang. Pest and disease control for wood ear mushrooms is mainly based on prevention, strengthening hygiene and disinfection of the cultivation environment. Temperature, humidity, ventilation, and light must also be well managed.
