In winter, pests such as mushroom mosquitoes and spring-flesh insects often cause serious losses in the production of edible mushrooms in a short period of time. Li Manxia, ​​a former researcher at the Vegetable and Flower Research Institute of Northwest Agriculture and Forestry University, said that the prevention and control of edible fungus pests and diseases should adopt physical prevention measures to avoid the occurrence of phytotoxicity and pollution to edible fungi.

Prevention should be targeted

Mushroom shed construction: should be away from villages, garbage dumps, dung and other places to ensure the mushrooming environment away from the source of insects, the raw materials can be exposed to strong sunlight, or fermented to kill the eggs, live insects, try to take cooked Cultivation or for seed production. Selection of strain quality: In the process of seed production, it must be carefully inspected, selected, and found to be contaminated and immediately eliminated to ensure the purity of the strain. The location of the insect nets: The vents and imports and exports of mushroom sheds are preferred, and the adult insects are prevented from flying in. Limes are isolated at the vents and the entrance and exit to prevent reptile pests from entering.

Comprehensive prevention

The prevention and control of edible fungus pests should be based on agricultural control so as to avoid pollution.

Water immersion method to control pests: Some of the pests are immersed in water and cause oxygen deficiency to promote the separation of the protoplasm from the cell membrane. Bottle cultivation and bag cultivation can inject water into bottles and bags. Block cultivation can immerse the cultivating blocks in water to make them heavy. After soaking for 2-3 hours, the larvae will die and float.

The use of pests to prevent and control the habits: some pests have obvious characteristics, some lepidopteran pests are large in size and bright in color, and can be captured manually. The gnat mosquitoes have the habit of larvae breeding. When they are afraid of being dry, the infestation bag will be exposed to sunlight for 1-2 hours or lime powder to make the insects dry and die.

Trapping and killing pests: For pests, gauze can be laid on a mushroom bed, and a freshly fried rapeseed cake can be sprinkled on a layer of gauze. When the gill is gathered on the gauze, the gauze will be soaked in concentrated lime water and the gill will be killed. Dead, trapped on mosquito moths with black lights or energy-saving lamps.

Pharmacy insect remediation: When there are live worms or eggs in the strains, the strains can be put into large plastic bags, and aluminum phosphide can be added in an amount of 4 pieces per cubic metre of space, and bags can be taken out in about 6 hours. Strong penetrating power, it can kill the surface layer and internal pests, but has no effect on the growth of mycelium and fruit bodies. When the fumigation is done, the mushroom house should be sealed. The operator needs to wear a gas mask and the mushroom room should be smoked. Closed for 48 hours, then air for 2-3 hours before entering.

Fruit Powder
