Control Methods and Technical Key Points for Gray Mold in Greenhouse Chinese Chives
When humidity inside a greenhouse for Chinese chives is high, gray mold is likely to occur. After the disease develops, pale grayish-brown to white spots gradually appear on the leaves from the tip downward, on both the upper and lower surfaces; after expanding, they become elliptical or spindle-shaped lesions and merge with each other into large dead patches. When air humidity is above 85% and the temperature is 15°C~20°C, warm and humid conditions favor the occurrence of this disease.

Occurrence Patterns and Control Methods of Kiwifruit Gray Mold
Kiwifruit gray mold mainly occurs during the flowering stage, young fruit stage and storage period of kiwifruit. In severe years, the incidence rate in orchards and during storage can reach more than 50%. Kiwifruit gray mold has become one of the main diseases affecting the healthy development of the kiwifruit industry. 1. Symptoms When young fruit (late May to early June) is affected, residual stamens and petals are densely covered with gray spores. At the initial stage, the fuzz on young fruit turns brown, the skin is infected, and in severe cases it can cause fruit drop. Contaminated stamens and petals attach to leaves and form concentric ring lesions centered on them; the lesions expand and leaves drop. If rain occurs, the disease develops more severely. After fruit is affected, gray-brown mycelium and spores form on the surface, followed by black sclerotia. During storage, fruit is easily infected by diseased fruit.
