Main Symptoms of Licorice Rust Disease
Licorice rust disease mainly damages the leaves and sometimes the stems. The back of the leaves initially develops circular, pale blisters, which turn into yellow-brown powder heaps after rupturing. When there are numerous spore heaps on the leaves, localized patches may form, and even the leaves may wither and fall off. Infected plants exhibit yellowing of leaves, stunted growth, and abnormal development.
