Causes and Control Methods of Pelargonium Leaf Curl Disease
Pelargonium leaf curl disease, also known as Pelargonium crinkle disease, is a viral disease that has only been found in the Shanghai area. Symptoms: The leaves of infected plants curl downward and become stunted. In severe cases, the plants die. Pathogen: The pathogen is Pelargonium leaf curl virus (PLCV). Disease pattern: The virus is transmitted by sap, grafting and soil; no vector insect has been found. In summer and autumn, the symptoms of the disease are not obvious, and the residual virus-carrying plant debris from pruning can spread the virus.
