Introduction to the key points of prevention and control of mushroom diseases and insect pests

Mushroom varieties are very many, more common in life are Pleurotus ostreatus, Flammulina velutipes, mushrooms, mushrooms and so on, taste differences. No matter what kind of mushroom, if there is a little improper management in the cultivation process, there will be invasion of diseases and insect pests. Let's take a look at the key points of mushroom disease and insect control technology.

1. Common mushroom pathogens

1. Gypsum mold. This mold generally occurs after the culture medium goes to bed, especially when the bed surface is relatively wet and the ventilation conditions are not good. The first words are a white mold spot, slowly turning brown, and finally turning into a yellow, grain-like thick object with an unpleasant smell.

Prevention and control methods: first, select a better fermentation medium; second, strengthen the ventilation of the mushroom room; third, if there have been miscellaneous bacteria, you can first sprinkle quicklime powder for disinfection.

2, walnut fleshy mold: This is also a very serious harm mold, with the smell of bleaching powder, generally said that the mushroom plague is brought by this mold. If the bacteria are found, they must be buried deeply to avoid spreading everywhere, and corresponding disinfection and sterilization measures should be taken. Remember to strengthen the ventilation in the mushroom room and stop spraying water.

If it is infected by other miscellaneous bacteria, proper ventilation, water spraying, etc., and then mixing the culture medium with carbendazim wettable powder according to the proportion, which can prevent the growth of hyphae at the same time.

In addition to mushroom mold disease, common brown spot disease, brown rot disease, is also able to cause mushroom death of a miscellaneous bacteria, if found the mushroom disease, need to be buried deep, and then indoor disinfection treatment.

II. Common pests of mushrooms

1. Fungus flies. This is one of the common pests in mushroom cultivation. It is also a relatively small fly. It can fly on its wings, lay eggs on the culture medium, hatch maggots, and then invade the tender stalk and come out of the cap. In this way, the mushroom will be bitten with many small holes.

2. Red spider. Red spiders are generally easy to identify, and when they appear, they appear dark red on mushrooms.

3. Bacteria and mites. The words of bacteria mites are generally common in the convex places on the surface of soil materials, like a layer of powdery objects scattered.

4. Jumping insects. Jumping bug is a kind of small insect that can jump. It usually appears when cultivating materials and covering soil. It also causes small holes on mushrooms, so it will affect the commodity value of mushrooms.

Once these pests appear, we can take some preventive measures:

First, treat the culture with relevant chemicals before entering the room, such as avermectin for mites. Second, mushroom houses can be fumigated with trichlorfon before feeding. Third, the choice of mushroom house is best away from chicken houses, warehouses, feed houses and other locations to avoid the spread of pests.
