Alternaria spp. is a malignant fungus in the summer and autumn production of edible fungi, which can bring devastating pollution to the production of edible fungi. Streptomyces has strong vitality, rapid growth and strong transmission capacity. It is difficult for mushroom farms to be used normally after the outbreak of streptomyces.
Alternaria spp. is a malignant fungus in the summer and autumn production of edible fungi, which can bring devastating pollution to the production of edible fungi. Streptomyces has strong vitality, rapid growth and strong transmission capacity. It is difficult for mushroom farms to be used normally after the outbreak of streptomyces. This heterozygous fungus usually does not occur at low temperature (below 20 degrees Celsius). The conditions are high temperature and high humidity (relative humidity above 95%).
The main control measures are:
Corn flour is a kind of edible fungus cultivated in summer. It is better not to use corn flour or a small amount (no more than 1%) when preparing cultivation materials.
Second, when compounding the culture material, adding a proper amount of "Mushroom Master" brand "Mushroom Doctor Emergency 120" sterilizer in the culture material can effectively control the occurrence of streptomyces. The proportion of Mushroom Doctor's mixing material is: each bag of Mushroom Doctor 400 grams can mix dry material 4000 jin. The method of adding mushroom to the culture medium is: first, mix all the raw and auxiliary materials evenly, then add 100 pounds of water to each bag of mushrooms, sprinkle it with water ladle or spray it in the culture medium, mix it immediately, mix it up as soon as possible, and then put it on the pan and sterilize it immediately. Keep in mind that the time from bagging to pot sterilization should not exceed 5 hours, (because the culture medium added some nutrients such as bran, especially suitable for the occurrence of various microorganisms and bacteria at room temperature around 30, so as soon as possible to pack the bacteria immediately on the pot with high heat to boiling point;
Third, the germination period, as far as possible to avoid the rainy season or maintain indoor ventilation, dry, lime sprinkled on the ground moisture-proof. Mushroom space interval 3-4 days with "Mushroom Master" brand streptospore a fumigation fumigation once, or with "Mushroom Master" streptospore every bottle of water 100 kg interval 3 days spray mushroom room;
Fourth, such as bottle (bag) inside, bottle mouth (bag mouth) found that there is a very fast growing white flocculent hyphae or white conidia ball should be timely picked out, and then the streptosporin bottle with 30 kg of water into a liquid medicine, and then the picked out of the bacterial bags, into the liquid rolling, when the development of orange-red; Balloon is very difficult to control, once a bag of red or white Streptomyces spores, can only be sprayed with Sormente 20 jin per bottle of water to kill, to this point when it is very laborious to deal with.
Keep in mind: do not talk about Streptomyces infection package randomly discarded in the mushroom room doorway or nearby, in order to avoid causing new sources of infection. Then the whole mushroom room will use the "Mushroom Master" brand chain sporoxin to prepare a full range of liquid spraying once, interval 3-4 days to re-spray once, or with magic sticker each bottle of water 60 Jin spraying the whole mushroom room.
