Prevention and treatment of blackhead disease of Flammulina velutipes

Flammulina velutipes is one of the common edible bacteria in our life, which has high nutritional value and wide artificial cultivation, but in cultivation, there are often many diseases that harm the yield and quality of Flammulina velutipes. The Black death is a common disease of Flammulina velutipes. Let's take a look at its control methods.

1. Symptoms

Blackhead, also known as bacterial brown spot, is a pseudomonas, which mainly causes brown rot of Flammulina velutipes, which has a great impact on the production of Flammulina velutipes. In general, the pathogen will only infect the surface tissue of the fruiting body and will not go deep. When the fruiting body occurs, a small yellow or brown discoloration area appears on the cover and gradually turns into a dark brown sunken round or irregular spot. In the extremely humid environment, there will be a layer of bacterial pus on the surface of the plaque, which has a foul odor. when the plaque is dry, the cover will crack and form an asymmetrical fruiting body. In severe cases, the disease spots will form into one piece, including the stalk, so that the fruiting body can not stand upright, there is mucus on the outside, and finally the whole mushroom turns dark brown until it rotts.

2. Occurrence conditions

The external conditions for the onset of the disease are mainly that Flammulina velutipes are in an environment of high temperature and high humidity, or when spraying water fog, the contaminated water fog is sprayed on the fruiting body, resulting in the invasion of bacteria. The internal reason is that Flammulina velutipes is not resistant to disease, so it is easy to infect the disease. In addition, the disease is also easy to occur when there are water droplets in the cover for a long time or when the humidity is too high. The poor ventilation effect of the mushroom room will aggravate the development of the disease. Appropriate temperature is also conducive to the outbreak of the disease.

3. Prevention and control methods

Clean up the diseased mushroom and abolish the cultivation materials in time, disinfect the mushroom house, bed frame and cultivation equipment thoroughly with Venus disinfectant and bleach solution regularly, and clean the mushroom house with high incidence of disease every day. Antifouling agents with high degree and high residue should not be used during removal. The breeding material must be fully fermented and put into production after thorough disinfection and sterilization. To avoid mushroom production in the season of high temperature and humidity, it is necessary to strengthen ventilation, cool down and dissipate heat, and reduce air humidity in a hot and humid environment. When mushroom is produced, the temperature must be controlled below 15 degrees Celsius. Once the temperature is too high, cooling measures must be taken, such as window opening, film opening, shading and so on.
