Pepper disease prevention technology

**Pepper Disease Prevention Technology** Pepper is a widely cultivated crop, but it is susceptible to various diseases that can significantly affect its yield and quality. Effective prevention and control methods are essential for ensuring healthy growth and high productivity. Below are some of the most common pepper diseases and their respective management strategies. **1. Pepper Rot (Fusarium Wilt)** This disease primarily affects seedlings and adult plants. Initially, the stems become soft and shrink, leading to wilting and eventual death. In mature plants, the fruits develop rot, and under humid conditions, white mold appears on the infected areas. Control measures include spraying the seedbeds with 10 ml of bacterial sterile water mixed into 20–30 kg of water. After the seedlings have developed, mix 15 kg of water with 1/2 bag of Chunyu No. 1 and spray evenly. This helps prevent fungal and bacterial infections while strengthening the roots and boosting plant immunity. **2. Pepper Stem Blight** This disease affects both seedlings and adult plants, especially the roots, stems, and lateral branches. Dark brown elongated spots appear, and the upper leaves turn dark, while the lower leaves remain green. The plant wilts from the bottom up, leading to defoliation and eventual death. The fruits may turn gray-brown with concentric patterns. To manage this disease, use a 58% Saifu solution diluted 400–500 times combined with one bag of Chunyu No. 1. This not only prevents the disease but also enhances plant immunity, protects flowers and fruits, and increases yield. **3. Viral Diseases** Viral infections can severely impact pepper yields, reducing production by 50–60% in early stages and even causing total loss in severe cases. High temperatures, dry weather, overcrowded planting, lack of water and nutrients, and the presence of pests like aphids and whiteflies increase the risk. Control strategies include: 1. Controlling aphids and whiteflies using fast-acting insecticides such as Knorr or Xel. Apply 15 kg of solution per acre to effectively reduce pest populations. 2. Improving irrigation and fertilization practices. Use 8 kg of fertilizer during flowering and fruiting to enhance plant resistance. 3. Applying chemical treatments such as Virus A or Ningnanmycin combined with 1 bag of Chunyu No. 1. This can help prevent viral infections and increase yield by about 30%. 4. If infection has already occurred, spray a mixture of Chunyu No. 1, Fushengling, and zinc sulfate in water to revive the plants quickly. **4. Pepper Gray Mold** This disease starts by infecting flowers, causing brown spots on young fruits. The leaves show "V"-shaped lesions starting from the edges and spreading inward. For effective control, apply a 10% Polyzone solution diluted 1000 times combined with bacterial sterilant at 1200 times. Alternatively, use 10 ml of 30% bacterial sterilant mixed with 10 ml of 50% phopamarin diluted 1000 times before or at the early stage of infection. Adding one capsule of Chunyu No. 1 can improve efficacy by about 30%, while also enhancing plant resistance and immunity. In conclusion, a proactive approach involving proper cultural practices, timely application of biological and chemical controls, and regular monitoring can greatly reduce the impact of these diseases on pepper crops. By implementing these strategies, farmers can ensure healthier plants, better yields, and more sustainable production.
