Occurrence Patterns and Control Methods of Asparagus Stem Rot
I. Symptom Characteristics Asparagus stem rot mainly affects young spears. Young spears may be infected as soon as they emerge from the soil. Water-soaked, irregular lesions appear on the young stems, expand around the stem, causing the stem tissue to disintegrate and rot, ultimately leading to the death of the young spears. Even if mildly affected plants do not die, their vigor is greatly reduced, the above-ground stems and leaves are weakened, the young stems are thin and weak, and the yield...

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.
