Several pests harming the mushroom shed

1. Mushroom fly: The larva is also known as bacillary worm. The main fruit-feeding fruiting body causes tunnels and affects the quality of the worm. The resulting wound is also susceptible to bacterial infection and rot. Mushroom flies should adopt different methods at different times. This mushroom has a large number of bacillary dysentery before it can be fumigated with dichlorvos in an amount of 0.90 kg/100 square meters. At the same time, another 0.15 kg of 1% potassium chloride or sodium chloride solution (with 5% salt) can be sprayed on each culture block. Water instead of); After the mushroom has bacillary dysentery can be sprayed rattan fine, insecticide ester, nicotine and other low-toxic pesticides. (Nicotinamide can be made by itself: Take 0.50 kg stems, add 5 kg of water and take the solution after boiling). In addition, ventilation should be strengthened, and the temperature and humidity in the shed should be adjusted to ameliorate the living environment of pests so as to prevent and control its damage. 2. Mushrooms: Mushrooms are the most harmful to larvae. In addition to foraging on the surface of culture materials, some also cover the mushroom buds to prevent the mushroom from growing normally. Control methods: Spray 500-800 times the trichlorfon after harvesting, and add nylon yarn at the door and window of the mushroom shed to prevent adult insects from flying into spawning and breeding. 3, bacillary dysentery: is a species of apes, individuals are small, crawling faster, mainly feeding fruiting bodies and hyphae cause harm. In the prevention and control, the insect source should first be immersed in the mushroom shed, because it is mainly derived from the various feeds between the warehouse and the feed. Therefore, when using the warehouse, chicken house, etc. as a bacterium culture room, it must be completely disinfected, and use lime to brush the wall before use. Digestion with dichlorvos 1 time; found during the cultivation of bacteria can be used to dipped in cotton balls, 50% dichlorvos hanging fumigation or spraying 1% sulfuric acid nicotine solution, can also be used pig bones and other things with the smell of thionite and other pesticides after spraying on the culture In the vicinity of the block, the scorpion was tempted and burned or burnt with boiling water. 4. Nematodes: Nematodes are colorless, small worms that are extremely small and only about 1 mm in size. The larvae invade the mycelia and fruit bodies, and at the beginning the caps turn black, and the entire fruiting body becomes black and rotted and has a foul smell. Control methods: steam to fully contact the culture material to kill all nematodes. After mushrooming, 50 mg/kg zinc sulphide can be sprayed on the culture block to control its damage. 5, worms: also known as ash insects. It has a flexible tail, bouncing freely, body wax, not afraid of water. It is often distributed on the surface of the mushroom bed or in a dark, damp place to bite fruit bodies. Before the mushrooming, 1:1000 times of dichlorvos plus a small amount of honey can be used. Or with arsenious acid preparations or organophosphorus preparations coated on sweet potato slices for killing. Generally, pesticides can not be used directly after fruiting. In this case, 0.25-0.50 kg of fresh orange peel can be cut into pieces, squeezed with gauze and squeezed, and then added with 0.50 kg of warm water and sprayed 2-3 times with a ratio of 1:20. Anti-fly worms have an effective rate of more than 90%. 6, quail: commonly known as slugs, mollusks, body exposed, no shell. They are afraid of light and afraid of heat. They hid in the bricks, stones, and earth seams during the day. They came out after dusk to feed on food and they hid before dawn. Control methods: Rice bran or bean cake is added with 2% calcium arsenate or aluminum arsenate to make poison bait. It can also use 15-20 times of sodium chloride solution to spray off the adults. 9–10 o'clock in the evening is their period of concentrated activity, which can be captured manually. 7, Hummer: Adult black, small body, slightly flat body, compound eye prominent, nymph orange. It mainly sucks the juice of the bacteria, which can lead to atrophy of the bacteria in severe cases. Control methods: Use 40% Dimethoate Emulsion 1500-2000 times liquid spray, or 90% trichlorfon, 50% malathion 1000-1500 times spray, control effect up to 80% -90%. 8, 蝼蛄 蝼蛄 蝼蛄 蝼蛄 蝼蛄 蝼蛄 蝼蛄 蝼蛄 蝼蛄 蝼蛄 蝼蛄 蝼蛄 蝼蛄 蝼蛄 蝼蛄. The formula is 50 grams of trichlorfon, rice bran or wheat bran 1500 grams of saute, 50 grams of sugar, 250 grams of white vinegar mixed well and spread on the ground. The lice and mosquitoes die immediately after eating. 9, other pests: pseudo-walking insects, cockroaches, four-butterfly potassium, etc. Available rattan fine 500-800 times liquid spray or 80% dichlorvos 1000-1500 times liquid spray can achieve better control effect; termites are southern one The major pests are mainly pests and other fungi. Digging nests and killing ants is an effective way to avoid or reduce the damage of termites. In addition, it is also possible to dig a small ditch around the mushroom shed and put the fresh skunk sticks evenly in the ditch and cover it with soil, which has a strong repellent effect on termites.
