Control Methods for Physiological Disorders of Tomato
Physiological disorders often occur during tomato cultivation and greatly affect yield and quality. The most common ones include deformed fruit, hollow fruit, blossom-end rot, fruit cracking, rib vein browning, sunscald, and poor coloration. Deformed fruit. It mainly occurs during the period of flower bud differentiation and development. Under low temperature, excessive fertilizer (especially excess nitrogen nutrition...

Key Technical Points for Preventing Physiological Diseases of Autumn Tomatoes
Early blight: After onset, concentric ring-patterned lesions appear on the leaf surface, dark brown, water-soaked. Before and after onset, spray with a 500-fold dilution of 70% mancozeb wettable powder, or a 400-fold dilution of 75% chlorothalonil wettable powder, once every 7 days, for 3 to 4 consecutive sprays.

Rice physiological red blight can be controlled with raw gypsum powder
Rice physiological red blight often occurs in cold-waterlogged mountain valley fields and in paddy fields where organic green manure has not fully decomposed. This disease mostly occurs at the tillering stage of rice, showing as very little tillering, leaves turning yellow-brown, and tea-brown irregular spots on the first and second leaves from the base; some mistake it for leaf blast. When the rice hills are pulled up, the root system is yellow-brown, and in severe cases black; the seedlings do not grow, commonly called "fa qiu". There are three main causes of physiological red blight: first, toxic substances such as hydrogen sulfide produced during the decomposition of green manure; second, some cold-waterlogged

Physiological Disorders of Mushrooms and Their Control Methods
Mushrooms are relatively sensitive to their environment. A poor cultivation environment will hinder their normal growth and development, produce various abnormal phenomena, and lead to reduced yields and lower quality. Common physiological disorders of mushrooms include excessive mycelial growth, hard opening of the caps, thin-skinned early opening, and the appearance of ground-button mushrooms and hollow-stem white-core mushrooms. They are described below: Symptoms of excessive mycelial growth: after the casing soil of the mushroom bed is watered, the fluffy mycelium of the mushroom will continuously grow toward the surface of the fine soil, and in severe cases will form a fine, dense, water-impermeable mycelial mat, thereby delaying the time of fruiting and reducing the
