Lesions may have a water-soaked appearance or may be brown or black, often with a yellow halo. Bacterial Leaf Spot is generally more of a problem during warm, wet weather. Leaves yellow and may drop.
Plants lose vigor and produce less chlorophyll.
Bacterial Leaf Spot is caused by wet plant foliage and injury. Avoid wetting foliage when watering. Space plants to allow adequate air flow. Do not injure foliage. Bacteria enter plants through wounds or natural openings.
