Several pests harming mushroom shed

1. Mushroom flies: the larvae, also known as maggots, mainly feed on the fruiting body to cause tunnels and affect the quality, and the wound is also easy to be infected by bacteria and rot. Different methods should be used to control mushroom flies in different periods. There are a large number of maggots in front of this mushroom, which can be fumigated with dichlorvos at the amount of 0.90 kg / 100 square meters, while 0.15 kg of 1% potassium chloride or sodium chloride solution is sprayed on each culture block (which can be replaced by 5% salt water). After mushroom, maggots can be sprayed with low-toxic pesticides such as fish rattan essence, pyrethroid, nicotine and so on. Nicotine can be self-made: take 0.50 kg of tobacco stem, add 5 kg of water to boil and spray the solution. In addition, ventilation should be strengthened and the temperature and humidity in the shed should be adjusted to worsen the living environment of pests and achieve the purpose of preventing and controlling the pests.

2. Mushroom mosquitoes: Mushroom mosquitoes are the most harmful in the larval stage. In addition to eating on the surface of the culture material, some of them form a net to cover the mushroom buds, so that the mushroom body can not grow normally. Prevention and control method: spray trichlorfon 800 times after harvest, and add nylon gauze at the door and window of the mushroom shed to prevent adults from flying in to spawn and reproduce.

3. Fungus lice: it is a kind of mites with small individuals and fast crawling. it mainly feeds on fruiting bodies and hyphae. When preventing and controlling, we should first stop the insect source from soaking into the mushroom shed, because it mainly comes from all kinds of feed in the warehouse and feed room, so when using the warehouse and chicken house as the culture room, we should thoroughly disinfect it, brush the wall with lime, and fumigate with dichlorvos once before use. During the culture period, it was found that the lice could be fumigated with 50% dichlorvos with cotton balls or sprayed with 1% nicotine sulfate solution, or fishy things such as pig bones could be sprayed with pesticides such as parathion and placed near the culture block to lure the lice up. Then take it out and burn it or burn it to death with boiling water.

4. Nematodes: nematodes are small colorless worms, only about 1 mm in size. The larvae invaded the mycelium and fruiting body, and the cap blackened at first, and then the whole fruiting body blackened and rotted and smelled moldy. Prevention and treatment: steam should be fully contacted with the culture material when steaming to kill all nematodes. After mushroom emergence, 50 mg / kg zinc sulfide can be sprayed with culture blocks to prevent and control the damage.

5. Jumper: also known as ash bug. It has a flexible tail, bounces freely, has a waxy body and is not afraid of water. Often distributed on the surface of the mushroom bed or in damp dark places to bite the fruiting body. Before mushroom emergence, dichlorvos can be trapped with 1000 times of dichlorvos and a small amount of honey. Or apply arsenite preparation or organophosphorus preparation to sweet potato slices for trapping and killing. Pesticides can not be used directly after mushroom emergence. At this time, 0.25ml fresh orange peel can be cut into pieces, wrapped with gauze to extract juice, and then sprayed with 0.50kg lukewarm water at 1:20 for 3 times. The effective rate of preventing jumping insects is more than 90%.

Slug: commonly known as slug, it is a mollusk with a naked body and no shell. They are afraid of light and heat, hide under bricks, stones and soil cracks during the day, come out one after another after dusk to feed, and hide again before dawn. Prevention and control methods: Rice bran or bean cake added 2% calcium arsenate or aluminum arsenate to make poison bait, can also be used 15 min 20 times sodium chloride solution ground spraying to dispel adults. At 10 o'clock in the evening, when they concentrate on their activities, they can be captured manually.

7. Thrips: adults are black, small, slightly flat, compound eyes protruding, nymphs orange-red. It mainly absorbs bacterial juice, which can lead to bacterial atrophy in severe cases. Control method: spray with 40% dimethoate emulsion 1500 Mel 2000 times, or 90% trichlorfon and 50% malathion 1000 Mel 1500 times spray, the control effect can reach 80% Mel 90%.

8. Mole cricket: the effect of bait is the best. Its formula is 50 grams of trichlorfon, 1500 grams of rice bran or wheat bran, 50g sugar, 250mg white vinegar and sprinkled on the ground. Mole cricket and mosquitoes die immediately after eating.

9. Other pests: pseudo-walking insects, borer, Sibanli potassium, etc., which can be sprayed with 500 murine 800 times liquid spray or 80% dichlorvos 1000 murine 1500 times liquid spray can achieve better control effect; termites are a major pest in the south, which is mainly harmful to Fuling and other fungi. Digging nests to kill ants is an effective way to avoid or reduce the damage caused by termites. In addition, the method of stink tree branches can also be used to dig a small ditch around the mushroom shed, put the fresh Toona sinensis branches evenly in the ditch and cover them with soil, which has a strong repellent effect on termites.
