Common pests and Control methods of Edible Fungi

1. The common pests harmful to edible fungi are mushroom mosquitoes, mushroom flies, mushroom mites, jumpers, slugs and so on.

two。 In the stage of bacteria culture, pests invade from the mouth of the bag or hole, bite the hyphae and spread miscellaneous bacteria, so that the hyphae can not grow or die normally, resulting in package destruction. In the fruiting stage, the pests invade the base of the fruiting body and feed on the fruiting body and the basal hyphae, which leads to the yellowing and death of the fruiting body, and can not produce the second or third tide mushroom, which seriously affects the yield.

3. Technical measures for pest control should be based on the principle of "prevention first". The main technical measures are as follows: ① selects a good mushroom house. Mushroom houses should be kept away from pig pens, cattle sheds, chicken sheds and garbage dumps. ② should improve the environmental hygiene around the mushroom house. Remove garbage and sewage and reduce the source of insects. ③ disinfection. The ground around the wall of the bacteria room was sprinkled with lime powder and sprayed with 1000 times of dichlorvos to kill insects. The broken ④ bag should be pasted with adhesive tape and the mouth of the bag should be sealed with paper. In the stage of mushroom emergence, ⑤ was sprayed with 5000-fold solution of "BS" every 2 days to kill the young larvae. If there are a large number of pests in ⑥, "BS" can be mixed into 800,000x liquid immersion package, which can kill the invading pests.

4. Attention should be paid to the careful use of dichlorvos, methamidophos and other pesticides in the mushroom emergence stage, so as not to cause abnormal mushroom 22 to cause mushroom poisoning.
