What kind of pests are easy to appear in the mushroom shed? What are the prevention and control measures?

Mushrooms, as a widely used food, have a very large demand in the market and can bring considerable economic benefits to vegetable farmers. Now greenhouse mushroom cultivation is very common, in the actual planting process is easy to appear what pests? What are the preventive measures?

1. What pests are easy to appear in mushroom sheds?

1. Mushroom flies

Larvae, also known as maggots, mainly feed on fruiting bodies to create tunnels that affect quality, and the wounds caused are also easily infected by bacteria and rot.

2. Mushroom mosquito

Mosquitoes do the most harm in larval stage. Besides eating on the surface of culture medium, some of them also cover the mushroom buds with nets, which makes the mushroom body unable to grow normally.

3. Nematodes

Nematode is a colorless worm, extremely small, only about 1 mm. Larva infestation mycelium and fruiting body, at the beginning of the cap black, after the entire fruiting body black rot and mildew odor.

4. Jumping insects

Also known as ash worm. It has a flexible tail, bounces freely, has a waxy body and is not afraid of water. It is often distributed on the surface of mushroom beds or in damp dark places to bite fruit bodies.

5. Slugs

Commonly known as slugs, mollusks, naked body, no shell. It is photophobic and afraid of heat. During the day, it hides under bricks, stones and cracks in the earth. After dusk, it comes out to feed and harm one after another. Before dawn, it hides again.

2. Pest control measures in mushroom shed

1. Mushroom fly control measures

Different methods should be adopted to control mushroom flies at different stages. A large number of maggots occur in front of this mushroom, which can be fumigated with dichlorvos according to the amount of 0.90 kg/100 square meters, and at the same time spray 0.15 kg of 1% potassium chloride or sodium chloride solution (which can be replaced by 5% salt solution) on each culture block; after the mushroom is damaged, rotenin, pesticide, nicotine and other low toxicity pesticides can be sprayed. (Nicotine can be self-made: take 0.50 kg of tobacco stems, add 5 kg of water to boil and spray the solution). In addition, ventilation should be strengthened to adjust the temperature and humidity in the shed to deteriorate the living environment of pests and achieve the purpose of preventing and controlling their harm.

2, mushroom mosquito control methods

After harvesting, spray 500-800 times of trichlorfon, and add nylon gauze at the door and window of mushroom shed to prevent adults from flying into oviposition and breeding damage.

3. Nematode control methods

Steam should contact the medium sufficiently to kill all nematodes. After fruiting, 50 mg/kg zinc sulfide can be sprayed on the culture block to control its damage.

4. Prevention and control methods of jumping insects

Before fruiting, it can be trapped by 1:1000 times of dichlorvos and a small amount of honey. Or use arsenious acid preparation or organophosphorus preparation coated on sweet potato tablets to trap. After fruiting, pesticides can not be used directly. At this time, fresh orange peel 0.25-0.50 kg can be cut into pieces, wrapped with gauze to extract juice, and then added with 0.50 kg warm water and sprayed with a ratio of 1:20 for 2-3 times. The effective rate of preventing jumping insects is more than 90%.

5. Slug control methods

Rice bran or bean cake added with 2% calcium arsenate or aluminum arsenate made of poison bait to kill, can also be used 15-20 times sodium chloride solution ground spray to drive out adults. 9-10 p.m. is their concentrated activity period, when artificial capture can be carried out.
