Introduction to the key points of control technology of mushroom nematode disease

Mushrooms are widely planted in China, and they are also the main source of economic income in some areas. According to the relevant information, most of the reasons for the poor harvest in mushroom cultivation are caused by nematode pests, so the prevention and control of mushroom nematode disease is very important. Let's take a look at the key points of the prevention and control of mushroom nematode disease.

Symptoms of mushroom nematode disease

Nematode is a kind of nematode that likes to live in an environment with suitable temperature and high humidity, especially in a humid environment of 18 degrees Celsius. If it is in hot weather and humid environment, the mortality rate of nematodes is relatively high. The nematode is a collective swimming pest, and if illuminated by light, you can also see white lines of floc moving on the surface of the covered soil or crawling in soil crevices. These white line-shaped things are formed by a large group of nematodes coiled together.

If the mushroom is attacked by nematodes, the culture material will have a black or smelly smell. A large part of the hyphae of the covered soil layer of the mushroom bed or the material surface that comes into contact with the soil particles will disappear, blacken and stink, and dead mushrooms are common on the bed. As the dead mushroom spreads, the mushroom cover will smell bad.

II. Control techniques of mushroom nematode disease

1. Prenatal prevention and control is the main measure. We should start with the improvement of the environment around the mushroom shed and do the work of prevention in advance. Clean up the garbage and weeds around the mushroom shed, and then make a good drain to create a favorable condition for mushroom growth. This work must be maintained not only before planting mushrooms, but throughout the process in order to effectively control the occurrence of nematodes and other diseases and insect pests.

2. During the germicidal period of the mushroom shed, ventilation should be strengthened and humidity and temperature should be well controlled, so that the incidence of diseases and insect pests can be reduced. The floor of the mushroom shed should also be disinfected regularly, quicklime can be used, and the specific dosage should be determined according to the area. Usually, we should pay more attention to observe the mushroom room to see if there is a peculiar smell, and timely check for possible diseases and insect pests. Because if nematodes are found early, they can be controlled with professional agents. It is also necessary to disinfect with quicklime outside the mushroom shed and do a good job of covering soil after controlling insect pests.

3. If nematodes have invaded the bedstead, different methods should be used to prevent and cure it. Usually pay attention to the mushroom shed ventilation work, pay attention to the safety of personnel when using drugs, so as to avoid poisoning. Usually do not let other outsiders into the mushroom shed to reduce the chance of infection.

4. The waste of the mushroom shed should be disposed of in time, should be discharged immediately after the end of the spring mushroom, and should be placed far away from the mushroom shed. The waste must be treated with drugs before it can be fermented and returned to the field so as not to affect the next round of mushroom cultivation.
