First, the symptoms:
The affected mushrooms initially show brown tumors on the cap and stem. These lesions gradually expand and eventually develop a layer of white mold on the surface. As the disease progresses, the mushrooms become deformed, turning into an amorphous white mass. Some mushrooms exhibit abnormally thick stems and distorted caps, while others shrink and soften. The infected areas often produce a brown, sticky mucus with a distinct odor, which is a clear sign of infection.Second, control methods:
1. Promptly remove the infected mushrooms along with the growing medium up to 10 cm deep, and dispose of them away from the growing area to prevent further spread. 2. Apply a protective spray using Bordeaux mixture (1:300 ratio) before the mushrooms start to grow. This can help reduce the risk of infection. 3. Improve ventilation in the mushroom house to lower humidity and regulate temperature. Maintaining optimal environmental conditions is crucial for preventing disease outbreaks.According to the latest forecast from the Anhui Meteorological Observatory, a cold air mass is expected to affect the region around the 15th, bringing precipitation. This weather change may have an impact on crops across the province, and farmers should pay close attention to it. According to the Provincial Center for Agricultural Meteorology, autumn crops in the Huai River region are currently in the yield formation stage, while mid-season rice is in the grain-filling and ripening phase. Some early-maturing rice varieties in the Jiangnan area are ready for harvest. Experts note that although the previous weather conditions were generally favorable for crop growth, post-harvest management remains essential to ensure a good yield of grains and cotton.
Currently, cold air activity is increasing, leading to a significant drop in temperatures. Chen Xiaoyi recommends that local authorities strengthen field management, particularly for late rice in double-cropping systems. Applying appropriate fertilizers can help promote growth, but it's important to raise the soil temperature before irrigation to avoid damage from low temperatures. In some regions, the first rice crop is maturing, so timely harvesting and proper drying before storage are critical. Autumn crops are in the final stages of yield formation, and precautions must be taken to protect soybean and corn from the adverse effects of low temperatures. Cotton is entering the boll-opening stage, so farmers should promptly pick mature cotton to ensure high-quality lint. Additionally, all regions should prepare for the upcoming autumn season in advance to mitigate potential risks.
