Causes and Control methods of Flower and Fruit drop in Pepper

Pepper is not only a common vegetable on our table, but also our main condiment. The annual output of the whole country is extremely high, but in the process of planting, the problem of falling flowers and fruits often occurs, which seriously affects the yield of chili peppers, and in serious cases leads to no harvest. It has caused huge economic losses to farmers. So what is the reason for the falling flowers and fruits of chili? How to prevent and cure it? Let's take a look at the pro-farm network.

1. Temperature discomfort

In the flowering period of pepper, when the temperature is too high and too low, it will cause pepper flowers in poor growth and development, resulting in the phenomenon of falling flowers.

Control method: strictly control the temperature during the flowering period of hot pepper, keep the suitable flowering temperature at 25-30 degrees and 15-20 degrees at night, if it exceeds this temperature range, it may cause flower drop. In addition, anti-falling element can be sprayed to protect flowers and fruits, but it is necessary to pay attention to the concentration and dosage of the agent.

2. Improper watering

In the flowering and fruiting period of hot pepper, too much water and too little moisture will bleed and drop flowers and fruits.

Control method: before the first inflorescence of pepper begins to set fruit, there is no need to water in general, unless there is a high temperature and drought period, pepper leaves wither. You can pour some water in moderation. During the flowering and fruiting period of chili peppers, you only need to keep the soil moist, with a maximum water holding capacity of more than 75%, and pay attention to oral humidity, which should not be too high.

3. Malnutrition

In the period of pepper germination and differentiation. If fertilizing improperly, nutrition disorders will also lead to flower and fruit drop, such as excessive nitrogen fertilizer at this time, it is easy to lead to flower and fruit drop, while after pepper planting, excessive fertilization will easily lead to pepper growth, flower and fruit drop will also increase.

Control methods: apply appropriate amount of nitrogen fertilizer during plant growth, fertilize according to the growth status of the plant, not one-sided fertilization, it is necessary to regulate the type and amount of fertilization to ensure the balance of nutrients needed for the growth of pepper.

4. Diseases and insect pests

Diseases and insect pests are also the main cause of pepper flower and fruit drop, a variety of diseases and insect pests can harm flowers and fruits, or harm roots and leaves, resulting in plants dying due to lack of absorption of nutrients and water, or leaves withering and shedding, unable to synthesize nutrients needed for growth through photosynthesis, resulting in flower and fruit drop.

Prevention and control methods: when planting, we must pay attention to the prevention and control of diseases and insect pests, spray pesticides at flowering stage can play a preventive role, find diseases should be dealt with in time, the right medicine.
