Latest Analysis of the Causes of Flower and Fruit Drop in Bell Peppers

Bell pepper cultivation is now very common in our country, with widespread distribution in both the north and south. When growing bell peppers, we need to do a good job of management, and careful management is the key to ensuring the normal growth of bell peppers. If management is poor, then bell peppers will develop many problems that affect their yield. One of these is flower and fruit drop in bell peppers. So what causes flower and fruit drop in bell peppers? Below, the editor will give everyone a brief introduction. Let's take a look together!

1. Temperature causes

Temperature is one of the main causes of flower and fruit drop in bell peppers. When growing bell peppers, if the temperature exceeds 35 degrees, the flowers and floral organs of the bell pepper will develop poorly as a result. The stigma of the style is prone to drying out, which affects pollination and fertilization of the flowers and leads to flower and fruit drop. In addition, in summer, when nighttime temperatures are high, the plants are prone to excessive vegetative growth, which can also cause flower and fruit drop. Therefore, during the day, we can take measures such as splashing mud slurry to lower the temperature, and at night we can open ventilation openings to cool things down. During the flowering period, the temperature should be maintained at around 25 degrees, with a day-night temperature difference of about 10 degrees.

2. Nutritional causes

During growth, bell peppers have a relatively large demand for nutrients and water. If the soil is dry and lacks water, then the absorption of fertilizer and water by the bell pepper will be affected, resulting in flower and fruit drop. However, water should not be excessive either. If there is too much, the soil becomes too sticky and heavy, which affects the respiration and growth of the bell pepper roots and may even cause root rot. Therefore, the soil should mainly be kept neither dry nor wet. Then, when fertilizing, ensure comprehensive nutrition and properly combine nitrogen, phosphorus, and potassium fertilizers. If there is too much nitrogen fertilizer or too little phosphorus and potassium fertilizer, bell peppers will drop flowers and fruit due to nutritional imbalance. Especially during the fruiting period, be sure to pay attention to the application of potassium fertilizer.

3. Other causes

In addition to temperature and nutritional causes, diseases and pesticide damage are also main causes of flower and fruit drop in bell peppers. This is especially true of viral disease. After bell peppers are infected with viral disease, the main symptom is plant stunting and dead growing tips, thereby causing flower and fruit drop. So if you want to prevent and control this disease, you must first eliminate aphids, because aphids are the main pests that carry the virus of viral disease. Then in summer, because the temperature is very high, when we use pesticides, we must pay attention to controlling the concentration of the pesticide. It must not be too high, otherwise it is easy to cause pesticide damage, which will likewise lead to flower and fruit drop in bell peppers,

The above is a brief introduction to the causes of flower and fruit drop in bell peppers. There are many causes of flower and fruit drop in bell peppers. When this phenomenon occurs, we should first identify the cause of the flower and fruit drop, and then carry out targeted prevention to reduce the phenomenon of flower and fruit drop. That is all for today's introduction. This article is for reference only, and we hope it can help everyone!
