The Latest Control Methods for Common Diseases and Pests of Wood Ear Mushrooms
Wood ear mushroom is a common delicacy in our daily lives. It is delicious, nutritious, and can be prepared in many ways, making it a popular food. Wood ear mushroom is developed from fungal spawn, but during cultivation it can also be harmed by other pathogens and insects. So how should these diseases and pests be controlled? Below, Qinong Web explains the control methods for several relatively common diseases and pests. Let's take a look.
1. Black wood ear mushroom green mold disease
When inoculating fungal bags or log segments, infection by green mold occurs. In the early stage of the disease, white mycelium appears on the culture medium or fruiting bodies, looking very similar to wood ear mushroom mycelium. 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 surrounding environment, keep the planting site well ventilated and easy to drain, and disinfect when entering and leaving the cultivation room to prevent pathogens from being brought in. After the wood ear mushrooms emerge, spray 1% lime water every day. When the disease has not yet fully broken out, you can also scrub the affected areas with a higher concentration of lime water, which can inhibit its growth.
2. Soft rot
Soft rot occurs in the late stage of fruiting body emergence. When the ear pieces are about to mature or have already matured, the ear pieces begin to soften or 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, soft rot is likely to occur. In addition, bacterial infection and pest damage can also cause soft rot in wood ear mushrooms.
Control methods: Strengthen management, pay attention to ventilation and lighting conditions, and harvest in time. Harvesting promptly when the wood ear mushrooms are about to mature or have already matured can avoid this problem. Oxytetracycline solution can be sprayed to prevent soft rot.
⟦NL>3. Thrips
Thrips, also called climbing pole insects, are relatively small as adults and black in appearance. They 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; in severe cases, it causes soft rot and leads to total crop failure.
Control methods: Pay attention to environmental hygiene, clean up fertilizer and contaminated bags in time, spread a layer of lime powder on the ground 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 them and eliminate the pest damage.
The above are the control methods for common diseases and pests of wood ear mushrooms brought to you by Qinong Web. The prevention and control of wood ear mushroom diseases and pests is mainly based on prevention, strengthening hygiene and disinfection of the cultivation environment. Temperature, humidity, ventilation, and lighting must also be well managed.
