The edible fungus has a yellowing death phenomenon, so that the mushroom farmers can't do anything. The Chinese pesticide net Xiaobian has compiled relevant information for the reference of the mushroom farmers, thus reducing losses.
1. Most of the recent disease types are brown rot, brown spot, and yellow spot.
The pathogens are Fusarium, Verticillium, and Xenopus. These pathogens have strong viability, low temperature tolerance, high humidity, and can grow normally at around 10 °C. They are common bacteria in late autumn to early spring. .
2, the cause of the disease.
Mainly due to improper management of low temperature season, the humidity in the mushroom shed may be too large in the low temperature season, excessive water spray, excessive free water attached to the mushroom body, can not evaporate after water absorption, resulting in weakening of the metabolism of the mushroom body, causing various pathogens to take advantage of , a large number of breeding, and cause various diseases of fruiting bodies; the second cause of the disease is the continuous low temperature weather for a while, causing the temperature in the mushroom shed to be too low, and the edible fungus body is in a bad living environment for a long time, causing the disease; Some edible fungi species are in the period of 3 to 4 出 in the mushrooming period, and the malnutrition in the bacterium is not well-fed. The fruiting body after the bud is not adequately supplied with nutrients, resulting in yellowing and death. Pesticide control should be carried out in a timely manner to recover losses as soon as possible.
3. The methods of prevention and control are as follows:
First, the mushroom shed should always spray all kinds of fungicides, such as bacteria killing, bacteria killing, mushroom cockroach king, gram mold, etc., generally can be sprayed once a week; second, when the mushroom shed temperature is too low, the water spray can not pass More, the humidity can ensure the normal growth of the fruiting body; the third is to increase the temperature of the mushroom shed as much as possible. According to the pesticide net , as the oyster mushroom, the shed temperature is better than 15 °C during the day; the fourth is to correctly understand all kinds of The warm type and normal growth temperature of the variety are managed in a targeted manner and managed correctly. Fifth, various types of disease-resistant and yield-increasing agents should be sprayed on the mushroom body. You can choose Mushroom Feng No. 1, Guangda Bacteria, Lixin Bacteria, Three-dimensional nutrient essence, mushroom guardian, mushroom more than life; six is ​​once the disease, can be sprayed with bacteria killing, mushroom killing, mushroom cockroach king, mushroom guardian, light bacteria king, Lixin bacteria king and other comprehensive prevention and treatment.
