Flammulina velutipes blackhead disease control methods! How to kill pests?

Flammulina velutipes is a kind of fungus similar to Flammulina velutipes, artificial cultivation technology is not complicated, as long as it can control the environmental conditions, it can produce stably, if not managed properly, it may get sick, such as blackhead disease. Here we would like to introduce the prevention and treatment of blackhead disease of Flammulina velutipes.

First, the introduction of Flammulina velutipes blackhead disease!

1. What disease is Flammulina velutipes blackhead disease?

Flammulina velutipes blackhead disease generally refers to Flammulina velutipes bacterial brown spot disease, is a pseudomonas, the bacteria are rod-shaped, the formation of white colonies, Gram staining negative reaction, infection will cause Flammulina velutipes brown rot disease, which has a great impact on production.

2. What are the symptoms of blackhead disease of Flammulina velutipes?

Blackhead is one of the main diseases of Flammulina velutipes, the pathogen generally only infects the surface tissue of the fruiting body, but does not go deep into the flesh. At the initial stage of the infection of the fruiting body, a small yellow or brownish discoloration area appears on the cover surface, and then it becomes a dark brown sunken spot, and the spot on the lid becomes round or oval or irregular, and the color deepens and adjoins into large irregular patches, resulting in light-colored mushrooms becoming yellow and dark mushrooms turning to sauce. In serious cases, the disease spots are linked together, including the entire stalk, so that the stalk all turn brown, can not stand upright, there is mucus, and finally the whole mushroom becomes dark brown or even rotten.

3. What is the cause of blackhead disease of Flammulina velutipes?

The internal cause of blackhead disease of Flammulina velutipes is the non-resistance of the variety, and the external cause is high temperature, high humidity or spraying dirty water to bring bacteria to the fruiting body, such as water droplets on the cover surface for a long time or excessive humidity is very conducive to the occurrence of the disease. poor ventilation can aggravate the development of the disease, and medium temperature conditions are suitable for the disease.

Second, how to prevent and cure blackhead disease of Flammulina velutipes?

Method 1. Clean and disinfect: keep the mushroom farm clean and sanitary, remove diseased mushrooms and wastes in time; thoroughly disinfect mushroom houses, bed frames and utensils before use, especially in mushroom sheds with serious primary diseases; do not use antifouling agents with high toxicity and high residue when mixing materials; culture materials should be sterilized thoroughly and soil-covered materials should be sterilized.

Method 2. Temperature and humidity control: the temperature of the mushroom during the mushroom production period should be controlled below 15 degrees, avoiding the high temperature and high humidity season, and strengthening ventilation and heat dissipation at high temperature. If the air temperature suddenly rises, cooling measures should be taken, such as opening the window, uncovering the film, shading and so on. However, the temperature fluctuation in the mushroom should not be too large to prevent water vapor condensation and produce water film.

Method 3. Cleaning and spraying: diseased mushrooms should be removed in time, and immediately increase ventilation, suspend or reduce water spraying, rapidly reduce the temperature, and spray to control the disease, such as spraying 500-1000 times bleach solution to the material surface, once every 2 days, the mushroom bed was stopped for 1 day before and after application, the medicine was used again every 3-4 days, and the diseased mushroom should be removed first when the disease was serious. Clean the material surface or cover the soil before spraying according to the above method.

Third, how to kill the pests of Flammulina velutipes?

The main pests of Flammulina velutipes are mushroom rope, sharp-eyed mushroom mosquitoes and mites, especially when the temperature rises. During the period of mycelial spread, insecticides should be used to control adults as long as they fly out. The most ideal insecticide is dichlorvos. Should be discontinued when mushroom buds occur.

The above is the introduction of the prevention and control methods of Flammulina velutipes blackhead disease and the methods of killing insect pests. I hope it will be useful to you.
