Flea Beetles are probably the most common pest, but a healthy eggplant should be able to withstand damage from their tiny holes. Damage is usually serious only on young seedlings. Grow plants under row covers until they are large enough to tolerate leaf damage. Remove garden debris in the fall to remove any overwintering beetles.
Powdery Mildew can affect eggplant. This appears as white, powdery spots on the leaves which may turn yellow and die. The best method of control is prevention. Planting resistant varieties when available, planting in full sun, and provide good air circulation. Water at the soil level, not on the leaves.
Other pest in Brinjal plants are caused by potato beetles, lace bugs, and mites. If the flowers on your eggplants form but then fall off, or if fruit does not develop, the most likely problem is that the temperatures are too cold.
