Pictures of pepper pests and diseases and their control methods

Peppers are something we must use in the kitchen in our daily lives; basically, we use them whenever we cook. Friends living in rural areas may all grow various peppers in their own fields, some spicy and some not spicy. In fact, peppers encounter many pests and diseases during cultivation, and the diseases differ at different growth stages. At such times, we need to use the correct methods to deal with them. Below, Shuaishuai will tell everyone about the various pests and diseases of peppers and their control measures!

I. Pepper damping-off and Rhizoctonia rot

1. Pepper damping-off

This disease is caused by low temperature and extremely high humidity in the seedling bed. Generally, after pepper seedlings emerge, they are very susceptible to infection by pathogens, so many black spots 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. Pepper Rhizoctonia rot

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 look very wilted, and they recover at night. When the lesions girdle the stem, the seedlings will die, but they will not fall over. This disease can be controlled by mixing Lusujing and Wanshuai solution and spraying the solution onto the surface of the plants.

II. 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, 80 percent Haoyi, 65 percent Haoshengling, and 75 percent Duobaojing can be used to spray the plants. If the disease has already occurred, Lusujing can be used for spraying, once a week, and after two consecutive sprays the condition can basically be brought under control.

III. Pepper gray mold

1. Symptoms

The main target of this disease is the leaves. Its pathogen begins to invade from the remaining petals, then after causing the petals to rot, it 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, Xingnong Yuegou, Xiangche, and Dr. Niu Trichoderma solution can be mixed for control.

IV. Pepper leaf blight

1. Symptoms

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

2. Control

Daikeli plus Chunleimycin mixed solution can be made into a spray for spraying control.

V. Pepper anthracnose

1. Symptoms

Pepper anthracnose is a disease that can harm the fruit. This disease can produce round yellow-brown spots. These spots are easy to recognize and are generally concentric circular, accompanied by some sticky matter inside.

2. Control

This disease is more prevalent in summer and autumn, and the incidence rate is highest in these two seasons. 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.

The above are the pictures of pests and diseases in pepper cultivation and their control methods. Have you all learned them? Seeing this, there must be diseases that everyone has encountered before. You can carry out control according to the methods introduced by the editor. Of course, if you have better methods, you are welcome to put them forward. I hope this can help everyone.
