First, living habits bacteria commonly known as "Bacteria", is the pest of the species and cultivation of edible fungi. Common pampas grass (small, brown, hi group, slow action) and whiteflies (larger body, white, happy, and quick action) are very strong in their ability to reproduce and are not easily visible to the naked eye. When it was discovered in large numbers, it has caused trouble for cultivation and can no longer be completely eliminated, making it hard for people to defend. Anthraquinones are mainly found in grain warehouses, henhouses, and other places, and are often brought into mushroom sheds through culture materials such as wheat bran and cotton husks, bacteria species, mosquitoes, flies, and tools. Aphid is very sensitive to the aroma of mycelia, and it is harmful to the hyphae that are used in seed production, germination and fruiting period.
Second, the endangering symptoms of bacillary dysentery direct access to mycelium, resulting in inoculation without bacteria or bacteria after the emergence of "fungus" phenomenon, so that the culture material black, or even rot. When the fruiting body is damaged, a large number of worms climb onto the fruit body and feed on the spores in the pleats of the bacteria. They inhabit in the pleats, and the damaged parts are discolored or have micropores, which not only affects the quality of fresh mushrooms, but also harms human health. If people eat a certain amount of bacteria, it will cause diarrhea and other intestinal diseases. When the number of pampas grasshoppers is large, common groups migrate to surface cultures or soil, such as a layer of yellow powder. If the palm or colored film is placed on the material surface for one minute, the presence of blemishes will be felt or observed.
Third, prevention and control methods Adhere to the "prevention-based, comprehensive prevention and control" approach, otherwise, once the damage is difficult to eliminate.
1. Mushrooms and strains should be kept away from warehouses, chicken houses, etc.
2. Strictly control the strains and strictly inspect the introduced strains for flaws.
3. Make sure the medium before sowing is free of mash.
1 Pharmaceutics mix: dilute 1000 times liquid distillate with 50% diazinon EC;
2 high temperature extermination: The fermentation of materials to be processed.
4. Mushroom house extermination:
1 Keep mushroom house clean. Timely removal of waste, mushrooms, etc., eliminating the source of transmission and transmission;
2 fumigation and killing. Closed mushroom shed, fumigation with aluminum phosphide, 8 ~ 10 g / cubic meter, highly toxic, pay attention to safety.
3 chemical killing. Dicofol, used in combination with phoxim; 25% detergent powder sprayed 1400 times; 1:1200 egg yolk; 0.15% malathion;500 times ketal; 50% omethoate 1000 times liquid; chrysanthemum ester 1500 times liquid and so on.
4 slay to kill.
a. Sweet and sour liquid trapping and killing: 1 part acetic acid, 1 part water, 0.2 parts sugar, mix and drop 1 to 2 drops of dichlorvos into sweet and sour liquid. Spread the liquid onto the material surface with gauze or cotton, and when the locust swarms on it, remove and burn it. Repeat the above operation. At low temperatures, after being sprayed on the surface of the bed, the mulch is covered and the curtains are heated up. The locusts hidden in the depths tend to accumulate on the surface and are destroyed by chemical agents.
b. Trapping the pork bones: The fresh bones are discharged onto a mushroom bed. After the mushrooms are collected, they are scalded with boiling water.
c. Rapeseed cake seduce: spread a damp cloth on the bed, sprinkle with freshly fried rapeseed cake, and induce it to burn.
d. Tobacco trapping and killing: fresh tobacco leaves are laid on the surface of the bed to attract, burn and repeat.
