In the fruiting stage, the phenomenon of falling flowers, falling fruits and falling leaves is called “three fallingsâ€. There are many reasons for the “three fallingsâ€. Generally, early falling flowers are mainly low temperature, and soil drought affects pollination. The "three falling" in the middle and late period is mainly caused by excessive or too little nitrogen fertilizer, causing long leaves or malnutrition, excessive density, insufficient light, high temperature and rain, pests and diseases.
To prevent and cure peppers, "three falling" should be done: 1. Cultivate strong seedlings. 2. Use well-drained sandy loam soil, avoid continuous cropping, and implement rotation. 3. Appropriate close planting, strengthen water and fertilizer management, coordinate plant growth and development, and avoid uneven fertilization. 4. Use different concentrations of anti-dropping spray according to the temperature. 5. Pay attention to the prevention and control of pests and diseases. Common anthracnose, bacterial leaf spot and mites are harmful, which can cause fruit drop and defoliation. It can be sprayed with 70% of a 600 times and 73% of gram of emulsifiable concentrate.
