At present, during the summer holiday period, Tianyingjiao (a type of chili pepper) production in Tianjin is also in its fruiting stage. Proper management plays a crucial role in ensuring high yield and quality. To maintain productivity and prevent losses, the following key practices should be carefully followed:
**I. Moisture Management**
As the current production phase is nearing the end of the fruiting period, it's essential to maintain consistent soil moisture. Ensure adequate water supply throughout this time. However, once the fruit starts ripening in late September, it's important to regulate irrigation to promote even coloring and maturation. In case of heavy rainfall, drainage should be prioritized to avoid waterlogging, which can damage the plants and reduce yield.
**II. Fertilization**
The fruit development stage is when the plant requires the most nutrients. In late June and early July, apply 5 kg of urea, 10 kg of diammonium phosphate, and 10 kg of potassium sulfate per acre. After mid-August, avoid applying nitrogen-based fertilizers to prevent delayed maturity. From mid-July to late July, you can combine pest control with foliar feeding using phosphorus and potassium-based solutions, applied every 7–10 days for best results.
**III. Pest and Disease Control**
1. **Disease Prevention and Control**
Early detection and timely intervention are key to managing diseases.
- **Virus Disease**: This is one of the major threats to Tianyingjiao. Symptoms include mosaic patterns, yellowing, necrosis, and deformed leaves. Apply imidacloprid every 15 days after infestation, and use 15% chlorfenapyr at 7-8 months. If infected, spray 20% virus disease A wettable powder diluted 500 times or antiviral agent No. 1 at 200–300 times. Repeat every 7 days for 3–4 times.
- **Blight**: This disease can cause severe crop loss. Upon detection, spray 500 mg of aluminum oxycarbonate manganese zinc or 75% antiviral agent at 200–300 times. Repeat every 7 days for 3–4 applications.
- **Anthracnose**: This causes leaf drop and fruit rot. Begin treatment from early July using mancozeb WP 400 times, 75% chlorothalonil 600 times, or 70% thiophanate-methyl 400 times. Spray every 7–10 days for 2–3 times.
- **Sunburn**: Caused by intense sunlight, especially on fruits. Prevent it through proper planting spacing and intercropping with tall crops.
- **Seedling Blight and Blast**: These affect young plants. Disinfect the seedbed soil and manage temperature and humidity carefully. Use 75% chlorothalonil 600 times or 70% mancozeb 500 times after germination, spraying every 7–10 days for 2–3 times.
2. **Insect Pests**
- **Cotton Bollworm**: The main pest affecting chili peppers. Control them before larvae reach the third instar. Use 50% phoxim EC 2000 times or 40% acephate EC 1000 times. Monitor and control pests on corn borders.
- **Locusts**: They reproduce quickly, so early control is essential. Use 40% omethoate 1000–2000 times or 50% phoxim EC 1500 times to treat seedlings.
- **Red Spider Mites**: These pests can occur over ten times a year. Use 50% dichlorvos 800 times, 20% triclosan 800 times, or 57% Kotel EC 800 times for effective control.
- **Cutworms**: Harm seedlings in their early stages. Use 50% phoxim 800 times or 90% dipterex 1000 times to target the roots and prevent damage.
By implementing these strategies, farmers can significantly improve the health and productivity of their Tianyingjiao crops during the critical summer season. Regular monitoring and timely action are essential to ensure a successful harvest.
