Analysis of the causes and cure measures of mushroom yellow mushroom

The edible fungus is currently experiencing a yellowing and dying phenomenon, leaving mushroom farmers in a difficult situation with limited options to prevent or treat the issue. To help farmers better understand and manage this problem, the **Chinese pesticide net** has compiled detailed information for reference, aiming to minimize losses and improve crop resilience. 1. **Common Disease Types** Most of the recent cases involve brown rot, brown spot, and yellow spot diseases. The primary pathogens responsible are *Fusarium*, *Verticillium*, and *Xenopus*. These pathogens are highly resilient, thrive in high humidity, and can grow at around 10°C. They are particularly prevalent during late autumn to early spring, making them a major concern for mushroom cultivation during these seasons. 2. **Causes of the Disease** The main cause is improper management during the low-temperature season. Excessive moisture in the mushroom house, often due to over-spraying, leads to water accumulation on the mushroom bodies. This prevents proper evaporation, weakens the mushrooms’ metabolism, and creates an ideal environment for pathogens to multiply, causing various fruiting body diseases. Another contributing factor is prolonged periods of low temperatures, which create a stressful living environment for the fungi. Additionally, some mushroom species may suffer from malnutrition if the substrate is not properly prepared. If the nutrient supply is inadequate during the budding stage, the resulting fruiting bodies may become weak, leading to yellowing and eventual death. Early intervention through **pesticide** application is crucial to mitigate damage and recover lost yields. 3. **Prevention and Control Methods** To prevent and control these issues, the following measures are recommended: - Regularly spray fungicides such as *Bacteria Killer*, *Mushroom Cockroach King*, *Gram Mold*, and others. A weekly application is generally sufficient. - During cold weather, reduce the frequency of watering to avoid excessive moisture buildup. Maintain optimal humidity levels to support healthy fruiting body development. - Increase the temperature inside the mushroom house as much as possible. For example, oyster mushrooms should be kept above 15°C during the day for best results. - Understand the specific temperature requirements of each mushroom variety and manage the environment accordingly. - Apply disease-resistant and yield-enhancing agents such as *Mushroom Feng No. 1*, *Guangda Bacteria*, *Lixin Bacteria*, *Three-Dimensional Nutrient Essence*, *Mushroom Guardian*, and *Mushroom More Than Life* directly onto the mushroom bodies. - In case of infection, use a combination of treatments like *Bacteria Killer*, *Mushroom Killer*, *Mushroom Cockroach King*, *Mushroom Guardian*, *Light Bacteria King*, and *Lixin Bacteria King* for effective disease control. By implementing these strategies, mushroom farmers can significantly reduce the risk of disease and protect their crops, ensuring more stable and profitable harvests.
