How to Manage Pests

Pests in Gardens and Landscapes

Windburn

If a strong, dry wind persists during the growth period of the foliage, the leaves in the most exposed areas develop small, dark lesions between the veins, twisting and folding the growing leaf. Many of these leaves drop.

Identification

Solutions

Although windburn may appear severe, it does not seem to affect the crop. Maintain a good fertilization and irrigation program to avoid deficiencies. Stress problems such as these may contribute to windburn symptoms.
