What diseases and insect pests may occur in the cultivation of Pleurotus ostreatus? How to prevent and cure?

In the specific planting process of Pleurotus ostreatus, it is likely that Pleurotus ostreatus is attacked by diseases and insect pests due to improper management and other reasons, resulting in the decline of Pleurotus ostreatus yield, poor quality and other phenomena, which brings great losses to the economy of the majority of growers. What diseases and insect pests may occur in the cultivation of Pleurotus ostreatus? How to prevent and cure?

Common diseases and control methods of Pleurotus ostreatus

The common diseases of Pleurotus ostreatus can be divided into physiological diseases and infectious diseases.

Physiological disease of Pleurotus ostreatus refers to an abnormal activity phenomenon caused by incorrect environmental factors and planting management methods in the process of Pleurotus ostreatus cultivation. Such as mycelial growth, Pleurotus ostreatus, Pleurotus ostreatus, Pleurotus ostreatus atrophy, rust spots, drug damage and so on.

1. Excessive growth of hyphae: refers to the relatively luxuriant growth of aerial hyphae on the surface of Pleurotus ostreatus hyphae, which affects the emergence of mushrooms. The occurrence of this disease is mainly due to the high humidity of the air and poor ventilation. Therefore, only by taking good ventilation measures and reducing the humidity in the mushroom shed can the disease be effectively prevented.

2. Pleurotus ostreatus: this disease is mainly caused by long-term hypoxia and poor ventilation, the cap of Pleurotus ostreatus fruiting body is very small, and the stalk is very thick and long. General attention to ventilation and light can prevent it.

3. Atrophy of Pleurotus ostreatus: in the long-term division of Pleurotus ostreatus cultivation by insufficient moisture and strong ventilation, the fruiting body stops growing, becomes dry and rotten. Therefore, in order to prevent the occurrence of this phenomenon, it is necessary to reasonably ventilate and increase the humidity of the air, so as to avoid the phenomenon of drying on the material surface.

4. Rust spot: rust spot is one of the common diseases in the production process of Pleurotus ostreatus, which mainly refers to the brown spots on the cap and stalk of Pleurotus ostreatus, which can be well prevented by reducing the humidity of the mushroom shed and strengthening ventilation.

5. Drug damage: it means that the cap of the fruiting body of Pleurotus ostreatus stops growing after medication, and the phenomenon of rolling or black edge appears on the edge of the lid of Pleurotus ostreatus, so the medication should be paid great attention to so as not to affect the growth of Pleurotus ostreatus.

The leachate disease of Pleurotus ostreatus has brown spot, and it is also one of the diseases that have a great impact on the growth of Pleurotus ostreatus, which will produce a layer of white villi hyphae on the surface of the fruiting body, and then brown spots will appear, resulting in dry cracking and shrinkage of the cap. At ordinary times, we should pay attention to the ventilation and cooling of the mushroom shed, and the place where the disease occurs can be sprayed with corresponding agents.

Common insect pests and control methods of Pleurotus ostreatus

The common pests of Pleurotus ostreatus are maggots, mites, jumpers, ants, cockroaches, mice and so on. Once they occur, they are also irreversible for growers, so it is necessary to do a good job in pest prevention according to their characteristics. Only in this way can we reduce the phenomenon that pests affect yield and quality.
