BLS – Bacterial Leaf Spot

Scientific Name: Xanthomonas campestris

Type: Bacterium

Bacterial Leaf Spot is a disease that affects the growth of peppers. It is one of most destructive diseases that affects peppers in the Eastern part of the United States. Symptoms may first develop on older plant leaves. Initially brown spots appear on the leaves. The leaves turn yellow and eventually die off. Heavy infestations may cause complete defoliation and cause sun scald. Scab like spots may develop on peppers and are unmarketable. It can cause significant yield loss and even total crops losses. The infected plants should be removed and burned to avoid further infestation. It is spread by seeds, weeds, by splashing rain, and by gardeners working with wet infected plants. Increase space between the plants to maximize air flow and drying of the leaves. The disease is favorable in areas with hot summers and frequent rainfall. Plan on using a 1 year crop rotation and avoid planting in the same location, year after year, as the disease can survive in the soil and infected plant debris. Proper tillage practices may be helpful in managing the disease. Cover the soil with black plastic mulch or black landscape fabric. Use drip irrigation or soaker hoses and avoid overhead watering. Copper fungicides can help manage the disease. The best option is to use disease-free and disease resistant varieties.
