This article provides a detailed explanation of the planting content of Ligularia crabapple at the Flower Clinic, including the prevention and treatment methods for its grey mold disease, as follows:
Symptoms of Ligularia crabapple Grey Mold Disease: Grey mold disease typically appears on the lower leaves of cuttings that come into contact with the potting medium. Water-soaked spots will quickly expand to infect most or even the entire cutting. Over time, the infected area will necrotize and turn brown to black.
When the night temperature is low, the day temperature is high, and humidity is also high, the pathogen can easily form spores on the leaves and develop grey-green conidial masses.
Prevention and Treatment Methods: Controlling grey mold disease is especially important when the greenhouse is closed in winter. Control the microenvironment, maintain air circulation; keep the leaf surface dry at night and reduce humidity; fungicides such as Yili and Grey Mold Rapid Relief can be sprayed.
The above comprehensive introduction to the prevention and treatment methods for Ligularia crabapple grey mold disease is hoped to bring some knowledge about green plants to green plant enthusiasts.
