What are the "green" control methods of edible fungus pests in spring?

Spring is the peak of the occurrence of edible mushroom pests, for vegetable farmers, this is an important period for pest control, so what are the "green" control methods of edible mushroom pests in spring?

I. principle of prevention and control

It is necessary to adhere to the principle of "prevention first and green control". If the prevention work is done well, the opportunity for the occurrence of insect pests will be eliminated. If the pest has appeared, it must be eliminated quickly and completely, and we cannot take a chance, thinking that the area of the pest is small and the occurrence time is not long, so we can wait and see if the situation has improved.

II. Prevention of insect pests

1. The effect of Quechongling

In the growth process of edible fungi, mushroom mosquitoes and mushroom flies often occur, they are mainly the adults lay eggs, the hatched larvae are harmful to edible fungi. According to the characteristics of pests, we can use efficient paracetamol, which can make the mushroom shed give off a smell that adults don't like, so as to escape from the mushroom shed.

two。 The usage of Quechongling

The use of paracetamol should be based on the number of insect sources in the mushroom shed, the environment and other conditions to make a solution of 200 to 300 times. When spraying, the ground, surroundings, vents, material beds and other places of the mushroom shed should be treated carefully. If the temperature is above 15 ℃, spray every 2 days or so; in the concentrated cultivation area, spray water in the shed every other day; when there is more waste around the mushroom shed and the environment is poor, you should spray other insecticidal drugs outside the shed at the same time, spray the insecticidal solution once a day in the shed for more than a week, and check to confirm that its density decreases significantly, and it can be maintained once every 3 days.

III. Extermination of pests

If a small amount of mushroom mosquitoes are found in the mushroom shed in spring, it can be killed by spraying low concentration pyrethroids in time, or after diluting Meisaoling with water 100 times, it can be aimed at the adult to increase the amount of spray so that its wings are stained with atomized water droplets, which can cause it to fall to the ground, but after its tiny insect body comes into contact with the wet ground, it is difficult to fly again and die in a few hours.

If the pest has occurred for more than a week, the larva population is small and the depth of entering the base material is not large, all the fruiting bodies can be collected, 1000 times of trichlorfon solution can be sprayed on the material surface, and the closed mushroom shed can be killed for about 12 hours.

The above is the introduction of the knowledge related to the "green" prevention and control of edible mushroom pests in spring, hoping to be helpful to the vegetable farmers who grow edible mushrooms.
