Control methods of common diseases and insect pests of Auricularia auricula

Fungus is a common delicacy in our life. It has delicious taste, rich nutrition and many ways to eat. It is a favorite food for people. Auricularia auricula is developed from bacteria, but its cultivation will also be harmed by other bacteria and insects, so how to prevent and control these diseases and insect pests? below, the pro-agricultural network explains the prevention and control methods for several more common diseases and insect pests. Let's take a look.

1. Green mold of Auricularia auricula

Inoculation in the bacterial bag or segment wood is infected with green mold, the initial culture material or fruiting body appears white hyphae, which is very similar to the mycelium of Auricularia auricula, the hyphae grow very fast, and conidia can be formed after a few days. Once the spores begin to form and mature vigorously, the colony will become green powder, which is the origin of its name.

Prevention and control methods: pay attention to the sanitation of the cultivation site and the surrounding environment, keep the planting site well ventilated and convenient for drainage, disinfect in and out of the culture room to prevent bacteria from entering, spray 1% limewater every day after the fungus comes out of the ear, and when the disease is still a full-scale attack, it can also be scrubbed with high concentration of limewater to inhibit growth.

2. Flowing ears

Ear bleeding occurs in the late stage of ear emergence, and when the ear piece is about to mature or has already matured, the ear piece begins to soften or even rot. It is a symptom of auricularia cell rupture, when the ear piece is mature, it will continue to produce spores and consume a large amount of fruiting body nutrition, resulting in fruiting body aging. At this time, it is easy to produce ear flow phenomenon if it is in the environment of high temperature and high humidity. In addition, bacterial infections and insect pests can also cause auricularia auricula.

Prevention and control methods: strengthen management, pay attention to ventilation and light conditions, harvest in time, harvest in time when Auricularia auricula is ripe or already mature, this problem can be avoided and oxytetracycline solution spray can be used to prevent ear bleeding.

3. Thrips

Thrips, also known as crawlers, have less adult size and black appearance, and are not easy to find in a dark environment. Its larvae begin to harm Auricularia auricula, invade the ear slices and begin to suck juice, causing auricularia auricula slices to atrophy, light to reduce production, and heavy ones to cause auricularia auricula, resulting in no harvest.

Prevention and control methods: pay attention to environmental hygiene, clean up fertilizers and pollution bags in time, sprinkle lime powder on the ground, eliminate the source of overwintering insects, and install door and window screens in the bacteria room to prevent insects from entering. When insect pests occur, they can be trapped and killed with sugar and vinegar, or sprayed with trichlorfon to exterminate insect pests.

The above are the prevention and control methods of common diseases and insect pests of Auricularia auricula brought by pro-agricultural network. The prevention and control of diseases and insect pests of Auricularia auricula is mainly based on prevention, strengthening the sanitary disinfection of the cultivation environment, such as temperature, humidity, ventilation and light.
