Disease conditions of the chicken-claw fungus in pollution-free cultivation

Livestock Farming 0 views
The shaggy ink cap mushroom (Coprinus comatus) is deeply favored by mushroom growers for its rich nutrition, delicious taste, tender and smooth flesh, and strong market demand. It has been widely cultivated across the country with very broad development prospects. However, in actual cultivation, mushroom growers are often troubled by a kind of Xylaria (commonly known as chicken-claw fungus). Due to neglected prevention and control, by the time large-scale infection appears, they randomly use some high-residue pesticides for treatment, which not only has no effect but also often causes the pesticide residues in the finished mushrooms to exceed the standard and affects product sales. For example, in mid-October 2006, Hubei Province

The shaggy ink cap mushroom (Coprinus comatus) is deeply favored by mushroom growers for its rich nutrition, delicious taste, tender and smooth flesh, and strong market demand. It has been widely cultivated across the country with very broad development prospects. However, in actual cultivation, mushroom growers are often troubled by a kind of Xylaria (commonly known as chicken-claw fungus).

For example, in mid-October 2006, 5 containers of edible mushroom products exported to Malaysia by a company in Sanligang Town, Suizhou City, Hubei Province, were returned because pesticide residues exceeded the standard, with direct losses reaching more than 300,000 yuan. This is a lesson. Now, in response to some technical difficulties that many mushroom grower friends have called to consult about, the answers are given together as follows:

1. Specificity: The chicken-claw fungus belongs to the ascomycetes. The specificity of this pathogen's infection and damage is extremely strong. So far, it has only been found to cause damage to the shaggy ink cap mushroom (Coprinus comatus).

2. Disease conditions: The chicken-claw fungus prefers high temperature and high humidity. Between 20°C and 35°C, it grows rapidly. When the temperature is below 20°C, the amount occurring decreases, but it can still cause damage. The primary infection condition of the chicken-claw fungus is mainly soil carrying the fungus. After the shaggy ink cap mushroom produces 2 to 3 flushes, the chicken-claw fungus begins to emerge. Wherever the chicken-claw fungus grows, the mycelium of the shaggy ink cap mushroom gradually recedes, no more mushrooms are produced, and there may even be a total loss of harvest. This alone is enough to prove how great its harm is.
