The Most Common Pepper Diseases and How to Control Them, Worth Saving

Peppers are one of the most widely grown vegetables. Whether in the cold conditions of certain regions or the hot southern regions, they can be grown. In the process of growing peppers, some diseases will occur. How do you control them when diseases strike? Today we have put together for you the most common pepper diseases and their control methods!

1. How do you control damping-off, the most common disease of peppers?

1. Symptoms of pepper damping-off: when the disease occurs, oval dark brown lesions form at the base of the stem of affected seedlings. In the early stage, diseased seedlings wilt during the day and recover at night, until they die.

2. Causes of pepper damping-off: sowing too densely, leading to poor ventilation.

3. Control methods for pepper damping-off

(1) Strengthen seedbed management, apply decomposed organic fertilizer, and increase phosphorus and potassium fertilizer;

(2) Prevent the soil from drying out and becoming wet alternately, and reduce root damage;

(3) Pay attention to reasonable ventilation to prevent diseases from occurring in the seedbed under high temperature and high humidity conditions.

2. How do you control white spot disease, the most common disease of peppers?

1. Symptoms of pepper white spot disease: the affected parts of the pepper plant mainly appear on the leaves. At first there are brown spots, then the edges become brown and the centers grayish white. It is extremely prone to occur on young leaves. The lesions will slowly expand, and if not treated, they will cause the affected leaves to turn yellow or drop off.

2. Causes of pepper white spot disease: long-term warm and humid conditions in the pepper growing area, insufficient soil fertility, rainy days and long-lasting dew are important causes of the disease, and weak plant growth can also lead to the disease.

3. Control methods for pepper white spot disease

(1) Choose disease-resistant varieties;

(2) Strengthen field management, and apply more organic fertilizer and phosphorus and potassium fertilizer;

(3) After harvest, promptly remove diseased plant residues and burn them in a centralized manner;

(4) Spray 7500-fold diluted Zhibaosu solution or 4000-fold diluted Duoxiaohao solution to enhance the disease resistance of the host.

3. How do you control verticillium wilt, the most common disease of peppers?

1. Symptoms of pepper verticillium wilt: pepper verticillium wilt generally occurs in mature plants during the flowering and fruiting stage. In the early stage, the leaf tips or leaf edges curl slightly upward first, and the leaves droop or drop off. In severe cases, all the leaves fall off, leaving bare stems.

2. Causes of pepper verticillium wilt: most reports say the seeds carry hyphae or conidia internally or externally.

3. Control methods for pepper verticillium wilt

(1) Select and breed disease-resistant varieties, and particular attention should be paid to looking for disease-resistant varieties or disease-resistant individual plants among varieties with strong stress resistance and in severely affected fields;

(2) Carry out crop rotation, preferably rotation with rice.

4. How do you control anthracnose, the most common disease of peppers?

1. Symptoms of pepper anthracnose: it mainly harms ripe fruits. On infected fruits, moist brown oval or irregular lesions appear first, slightly sunken, with obvious concentric ring-like small orange-red granules on the lesion surface, which later turn into small black dots.

2. Causes of pepper anthracnose: in hot seasons, the fruits become sunburned and are extremely prone to anthracnose.

3. Control methods for pepper anthracnose

(1) Save seeds from disease-free fruits to reduce the initial source of infection;

(2) Remove diseased plant residues, and turn and sun-dry the soil after harvest and before sowing;

(3) Plant disease-resistant varieties;

(4) After harvesting the fruits, clean up the field and remove diseased fruits and diseased plant residues left in the field.

5. How do you control early blight, the most common disease of peppers?

1. Symptoms of pepper early blight: leaf lesions are round and dark brown, with black mold layers when moist. When stems are affected, black mold grows on the surface. Ultimately it causes the leaf tips and terminal buds to rot.

2. Causes of pepper early blight: the disease develops relatively quickly under warm and humid conditions, and repeated infection occurs many times through airflow and rainwater.

3. Control methods for pepper early blight

(1) Choose disease-resistant varieties and carry out crop rotation for more than 2 years;

(2) Save seeds in disease-free areas or from disease-free plants to prevent seeds from carrying the pathogen.

(3) Raise seedlings in disease-free areas, or use soilless seedling techniques, to prevent seedlings from carrying the disease.

6. How do you control bacterial wilt, the most common disease of peppers?

1. Symptoms of pepper bacterial wilt: the fine roots of the plant first turn brown, and soon begin to rot and disappear.

2. Causes of pepper bacterial wilt: it mostly occurs in continuous cropping fields and alluvial soil fields with a high groundwater table and high humidity. The seedbed soil should be disinfected and replaced in a timely manner, and crop rotation should be carried out.

3. Control methods for pepper bacterial wilt

(1) Carry out farmland crop rotation;

(2) Improve farmland soil and optimize cultivation methods;

(3) Grow strong seedlings and spray micronutrient fertilizer.

The above are the control methods for the six most common diseases of peppers that we have put together for you. We hope they can help grower friends in need. This article was compiled from the Internet.
