Last Updated: 2024/09/20, When the relative humidity of the air is too high, a large number of clump aerial hyphae will be produced on the surface of the mycelium, affecting the fruiting. The solution is to reduce humidity and increase ventilation. When excessive water spray, air humidity exceeds 95% and poor ventilation, the cap and stipe can produce brown spots. At this time, ventilation should be strengthened to reduce humidity. Withering medium is too dry, air humidity is too low, mushroom buds or fruit bodies stop growing, shrivel and dry, or even die and rot. Water should be added reasonably, relative humidity should be adjusted, and ventilation should be properly controlled. zishi

When the relative humidity of the air is too high, a large number of agglomerated aerial hyphae will be produced on the surface of the mycelium, which will affect the emergence of mushrooms. The solution is to reduce humidity and increase ventilation.

When the scab sprays too much water, the air humidity exceeds 95% and the ventilation is poor, the cap and stalk can produce brown spots. At this time, ventilation should be strengthened and humidity should be reduced.

When the wilt medium is too dry and the air humidity is too low, the mushroom buds or fruiting bodies stop growing, shrink and dry, and even die and rot. We should reasonably replenish moisture, adjust relative humidity and correctly master ventilation.

The fruiting body is deformed like coral, with thick root, long stalk and small cap, which is caused by hypoxia and poor ventilation, so ventilation should be strengthened.

Dry bubble disease, also known as brown spot, the surface of the fruiting body has white villous hyphae, raw brown spots, and the cap is shrunk and cracked. Prevention and control methods: spray 2% formaldehyde solution or 1 Gluconium 500 times carbendazim, and strengthen ventilation.

The fly is shaped like a black fly and lays eggs at the base of the stalk. Larvae, such as maggots, can bite stalks, caps and mycelia. It can be sprayed with 800 times high-efficiency and low-toxic pesticides, or you can light a lantern at night and put a piece of tin covered with tung oil behind the lamp. When the fungus fly hits the lamp, it is glued to the tung oil and dies.

Red spider is a small yellow-red mite that can harm mycelium and fruiting body. It bites the lid and fold of bacteria. Rusty yellow spots appear on the surface of the cap. Can be sprayed with 1 500mL 1000 times dimethoate or stone sulfur mixture (10mL).

Jumping insects like to bite the fruit body, which can be sprayed with 0.1% ivy essence for prevention and control.
