How to identify edible fungi attacked by armyworm? What are the prevention and control methods?

Armyworm is one of the common diseases and insect pests in the cultivation process of edible fungi, also known as leaf-eating pests. For edible fungi, once the disease occurs, it will undoubtedly be a big blow to growers, and it is basically a phenomenon of reduced production and quality. Let's take a look at how to identify edible fungi attacked by armyworm. What are the prevention and control methods?

First, how to identify edible fungi attacked by armyworm?

Armyworm is mainly through eating straw mushroom, Pleurotus ostreatus, Ganoderma lucidum, Auricularia auricula and other edible fungi as a harmful fungus, when eating these edible fungi will discharge a large number of pollutants on the edible mushroom and mushroom bed, inducing other miscellaneous bacteria infection.

The performance of different edible fungi is different when they are attacked by armyworm. The larvae of armyworm mainly bite the flesh of the front of Pleurotus ostreatus, leaving the epidermis on the back. When attacking Ganoderma lucidum, it mainly eats its fungus meat, which leads to a curved tunnel inside it. If it is against other fungus species, the fruiting body will appear irregularly shaped holes.

Second, what are the methods of prevention and control of armyworm invasion of edible fungi?

1. Before using the mushroom house, the mushroom room must be closed and then fumigated with professional agents, so that the eggs of armyworm can be effectively killed and the occurrence of insect pests can be reduced.

2. The new edible fungi and the old edible fungi in the mushroom room can not be mixed together. The waste things should be disposed of after each season is harvested, and all the disinfection measures can be done in the mushroom room before the edible fungi can be replanted.

3. After the larvae of the armyworm are found in the bacterial bag, we can choose the way of trapping to kill the armyworm. First of all, the insect mites are mixed with water according to the instructions and then sprayed on the mouth of the bacterial bag, mainly adding sugar and vinegar. Because the pest likes to eat sweet and sour things, when it smells the sweet taste of the bag, it will climb out of the bag and suck these drugs and die.

If there are not many edible fungi planted, when the larvae occur, they can be treated with chemicals after picking edible fungi, so that they can effectively kill the armyworm in the fungus bag and replenish the water in the fungus bag.

4. During the period of edible fungus cultivation, the edible fungus shed can be closed at an interval of four days, and then fumigated again by fumigation, the germicidal effect is very good.

5. In the greenhouse of edible fungus cultivation, the test tube should be checked and fumigated regularly, and then the test tube should be stuffed with cotton balls, and then a layer of Kraft paper should be stuffed on the outside, which can prevent pests from invading.

To sum up, if edible fungi are attacked by armyworm, the consequences are more serious, which has a great impact on the yield and quality of edible fungi. So growers must pay more attention to sterilization, disinfection and other measures at ordinary times, and every step must be done well.
