Leaf Curl

Plant Disease or Pest Leaf Curl
Leaf curl is a plant disease

Leaf curl is a plant disease characterized by curling of leaves, and caused by a fungus or virus. Leaf Curl is distinctive and easily noticeable, and the severity of the symptoms depends on how early infection has occurred.

Diseased leaves can usually be identified soon after they emerge from the bud, due to their red color and twisted shape. As the leaves develop, they become increasingly distorted, and ultimately thick and rubbery compared to normal leaves. The colors of the leaves may change from the normal green to red and purple. Changes in the bark are less noticeable, if at all. Fruit may fail to develop from diseased blossoms, or may be affected, showing a reddish color and infected leaves fall early.
