A Detailed Explanation of the Causes of Flower and Fruit Drop in Chili Peppers and the Prevention and Control Methods

Chili peppers are a common vegetable on our dining tables and also our main seasoning, with extremely high national production every year, but during the cultivation process, the problem of flower and fruit drop often occurs, seriously affecting the yield of chili peppers, and in severe cases leading to total crop failure, causing huge economic losses to farmers. So what are the causes of flower and fruit drop in chili peppers? How should it be prevented and controlled? Let's take a look together with Qinnong Web.

1. Unsuitable temperature

During the flowering period of chili peppers, temperatures that are too high or too low will cause poor growth and development of the flowers, leading to flower drop.

Prevention and control methods: Strictly control the temperature during the flowering period of chili peppers, maintaining the suitable flowering temperature at 25-30 degrees, while keeping it at 15-20 degrees at night. If it exceeds this temperature range, flower drop may occur. In addition, anti-drop agents can be sprayed to protect flowers and fruits, but attention must be paid to the concentration and usage amount of the chemicals.

2. Improper watering

During the flowering and fruiting period of chili peppers, too much or too little water can also cause flower and fruit drop.

Prevention and control methods: Before the first inflorescence of chili peppers begins to set fruit, generally no watering is needed, unless there is a high-temperature drought period and the chili pepper leaves wilt. A moderate amount of water can be applied. During the flowering and fruiting period of chili peppers, it is only necessary to keep the soil moist, with a maximum water holding capacity of over 75%, and also pay attention to oral humidity, keeping oral humidity at 60%, and it should not be too high.

3. Nutritional imbalance

During the sprouting and differentiation period of chili peppers. If fertilization is improper, causing nutritional imbalance, flower and fruit drop can also occur. For example, applying excessive nitrogen fertilizer at this time can easily lead to flower and fruit drop, and after chili peppers are planted, excessive fertilization can easily lead to excessive vegetative growth, increasing the probability of flower and fruit drop.

Prevention and control methods: Apply an appropriate amount of nitrogen fertilizer during plant growth, fertilize according to the growth condition of the plants, avoid one-sided fertilization, and regulate the types and amounts of fertilizer applied to ensure balanced nutrition needed for chili pepper growth.

4. Pests and diseases

Pests and diseases are also a main cause of flower and fruit drop in chili peppers. Various pests and diseases can harm flowers and fruits, or harm the root system and leaves, causing plants to wither and die because they cannot absorb nutrients and water, or causing leaves to wither and fall off, unable to synthesize nutrients needed for growth through photosynthesis, leading to flower and fruit drop.

Prevention and control methods: When planting, attention must be paid to the prevention and control of pests and diseases. Spraying chemicals during the flowering period can play a preventive role. If diseases are found, they should be dealt with promptly and treated with the right remedy.
