Common Green Pepper Plant Diseases:
How to Identify and Treat

Green peppers are a popular vegetable among home gardeners. They are easy to grow and have a high yield, making them an excellent addition to any garden. However, like any other plant, green peppers are prone to diseases that can affect their growth and yield. In this article, we will discuss some of the common green pepper plant diseases, how to identify them, and the best ways to treat them.

Blossom End Rot

Blossom end rot is a common problem in green pepper plants. It is caused by a lack of calcium in the soil, which leads to the formation of black or brown spots on the bottom of the fruit. The spots start small but can quickly grow larger and eventually cause the fruit to rot.

To treat blossom end rot, you need to ensure that your soil has adequate calcium. You can do this by adding lime or gypsum to your soil before planting. If your plants have already developed blossom end rot, remove the affected fruit and treat the remaining plants with a calcium-rich fertilizer.

Bacterial Spot

Bacterial spot is another common disease that affects green pepper plants. It is caused by a bacterium called Xanthomonas campestris, which causes small water-soaked lesions on the plant’s leaves and fruits. As the disease progresses, the spots become larger and turn brown or black.

To treat bacterial spot, remove any infected plants immediately and dispose of them. Avoid watering your plants from above as this can spread the bacteria. Instead, water at the base of the plant. You can also use copper-based fungicides to prevent the disease from spreading.

Phytophthora Blight

Phytophthora blight is a fungus that affects green pepper plants during hot and humid weather conditions. It causes wilting of leaves and stems, as well as brown or black lesions on the stems and fruits. The disease spreads quickly and can cause significant damage to your crop.

To treat phytophthora blight, remove any infected plants immediately and dispose of them. Avoid overwatering your plants as this can promote the growth of the fungus. You can also use fungicides to prevent the disease from spreading.

Verticillium Wilt

Verticillium wilt is a soil-borne fungus that affects green pepper plants. It causes yellowing and wilting of leaves, as well as stunted growth. The disease spreads slowly but can cause significant damage to your crop over time.

To treat verticillium wilt, remove any infected plants immediately and dispose of them. Avoid planting green pepper plants in the same area for several years as the fungus can survive in the soil for a long time. You can also use fungicides to prevent the disease from spreading.
