leaf blight

Leaf blight is a plant disease that causes browning and death of foliage, leading to the falling of leaves. This condition can affect various parts of a plant, including leaves, flowers, fruit, and stems, giving them a scorched appearance.123

Blights are typically caused by bacterial or fungal infections and are more common in cool, moist conditions. Economically significant plants like tomatoes, potatoes, and apples are susceptible, as are many ornamental species.2

Controlling blights involves removing infected parts, using disease-free or resistant varieties, crop rotation, and ensuring good air circulation. For bacterial blights, antibiotics like streptomycin can be used, though antibiotic resistance is a concern.23
