What does Leaf Curl mean?

In botany, leaf curl refers to a plant disease that leads to or creates leaf malformation. In most cases, leaf curl is triggered by a fungus invasion (fungal pathogen) or a virus.

Leaf curl often affects almond trees, nectarines, and peaches and is commonly found in New Zealand, America, Australia, Africa, and Asia. According to botanists, this plant disease was first introduced to America in 1852.

More On Leaf Curl

While leaf curl is easily noticeable, the symptoms vary according to the severity of the disease. Infected leaves tend to turn red and have a twisted shape. Depending on the plant, some leaves may even turn purple, yellow, or orange.

If the plant is severely affected, the leaves can actually emerge infected from the bud. If the leaf curl is not treated, the leaves will deteriorate, becoming even more rubbery and distorted. During the late stages, the leaves can display a white coat. Leaf curl also affects the rest of the plant, preventing fruits from developing.

The only way to successfully treat and control this condition is through the use of fungicides that contain MCE. Products with a higher level of MCE are more efficient, but these can cause more damage to delicate plants.
