During the planting process, chili peppers actually encounter many pests and diseases, and the diseases differ at different growth stages. At this point, we need to use the correct methods to deal with them. Below, Shuaishuai will tell everyone about the various pests and diseases of chili peppers and their control measures!

I. Chili pepper damping-off and Rhizoctonia rot

1. Chili pepper damping-off

This disease is caused by low temperature and extremely high humidity in the seedling bed. Generally, after chili pepper seedlings emerge from the soil, they are very susceptible to infection by pathogens, which causes many black spots to grow at the base of the seedlings. Gradually, these black spots worsen along the stem, and finally erode the entire stem, causing the stem to lose its supporting ability and fall over. This disease can be controlled by applying chemicals. We can add 200 grams of Chongchaling agent to the nutrient soil, or mix it with Guakuning for use.

2. Chili pepper Rhizoctonia rot

Chili pepper Rhizoctonia rot is a disease in which brown spots grow on the stems of diseased seedlings. Once infected with this disease, the stems and leaves will wilt and then die. Generally, during the day they appear very wilted, and they recover at night. When the lesions surround the stem, the seedling will die, but it will not fall over. This disease can be controlled by mixing Lusujing and Wanshuai solutions and spraying the solution onto the surface of the plants.

II. Chili pepper Phytophthora blight

1. Symptoms

This is a fatal disease. Its stems, leaves, and fruits are all targets of infection and can all be infected. Generally, after infection, some dark green lesions appear, which then slowly develop into dark brown lesions, causing the plant to rot and the leaves to die. This disease develops very quickly. Once it is infected, it will immediately infect the surrounding area and spread outward. It is a relatively dangerous disease.

2. Control

For the control of this disease, before it occurs, you can spray the plants with 80 percent Haoyi, 65 percent Haoshengling, and 75 percent Duobaojing. If it has already occurred, you can spray with Lusujing once a week, and after two consecutive sprays, the condition can basically be controlled.

III. Chili pepper gray mold

1. Symptoms

This disease mainly targets the leaves. Its pathogen begins to invade from the remaining petals, then causes the petals to rot and slowly spreads to the leaves. Therefore, when the disease occurs, we can see a gray mold layer.

2. Control

Use Lanchao solution, Kaimeirun solution, and Xiuliang solution. In addition, you can mix Xingnong Yuegou, Xiangche, and Dr. Niu Trichoderma solution for control.

IV. Chili pepper leaf blight

1. Symptoms

This is a disease that harms the leaves and is very common. Generally, once it occurs, it causes yellowish-brown spots on the leaves, which slowly become larger and larger, then cause the leaves to wilt and fall off.

2. Control

You can use Daikeli plus Kasugamycin mixed solution to make a spray for control.

V. Chili pepper anthracnose

1. Symptoms

Chili pepper anthracnose is a disease that can harm the fruits. This disease can produce round yellowish-brown spots. These spots are easy to see and are generally concentric rings, accompanied by some sticky material inside.

2. Control

This disease is more prevalent in summer and autumn. The incidence rate is highest in these two seasons, and the incidence rate is even higher in growing environments with poor ventilation. Everyone can improve the environment, keep the environment ventilated, and then use it once every five to seven days. After about three sprays, it can recover.
