Why Do Chili Plant Leaves Curl Up?
Core Guide: This article discusses the reasons why chili plant leaves curl up, including knowledge about flowers and plants. If there are any mistakes, please feel free to correct them!
Why Do Chili Plant Leaves Curl Up?
In the hot summer weather, the evaporation of soil moisture is relatively high, which can lead to the chili plants being unable to absorb moisture during the growth process, causing the leaves to curl up. During the summer, high temperatures can make it difficult for most crops to endure, leading to curled leaves in chili plants. It may also be due to excessive use of pesticides, which can make the chili plants grow worse and cause the leaves to curl.
With the improvement of people's living standards, the demand for chili in the market is also high. Many people grow their own chili, and problems often occur during the planting process. So, why do chili plant leaves curl up?
Why Do Chili Plant Leaves Curl Up?
1. Insufficient Water
In the summer, with the hot weather, the evaporation of soil moisture is high, leading to the chili plants being unable to absorb moisture, causing the leaves to curl up.
2. Excessive Use of Pesticides
During many planting processes, if farmers feel that the chili plants are not doing well, they resort to using pesticides, insecticides, and herbicides. The more pesticides used, the worse the chili plants grow, resulting in curled leaves.
3. High Temperature
In the summer, during the growth process of chili plants, temperatures can reach up to 40 degrees Celsius. Most crops find it difficult to endure such high temperatures, leading to curled leaves in chili plants.
4. Diseases and Pests
Tea yellow pests can cause chili plant leaves to curl up. In this case, we need to take measures to control them and deal with the issue promptly to prevent more chili seedlings from being affected.
How to Treat Curled Leaves on Chili Seedlings
1. Reasonable Watering: We should water appropriately, preferably with frequent small amounts of water. After watering, observe if there is any improvement in the growth of the leaves. If there is no improvement, we need to look for other reasons and take corresponding control measures.
2. Handling Curled Leaves: We should remove the curled chili leaves according to the situation to avoid affecting the growth of the entire plant.
3. Adding Sunshade Nets: We can cover the chili planting area with sunshade nets to prevent direct sunlight from causing the leaves to curl up.
4. Control of Diseases and Pests: If the planting area is small, we can manually remove pests. If the planting area is large, the most effective method is to spray pesticides.
What Medication to Use for Severe Curled Leaves on Chili Plants
1. Malic Acid Methyl Guanidine, containing plant-derived growth hormone organic water-soluble fertilizer foliar spray
For chili leaves curling caused by mosaic virus disease, we can change the environmental conditions to avoid high-temperature and dry environments.
When virus disease occurs, it is best to use medication promptly at the early stage of the disease. We can use malic acid methyl guanidine containing plant-derived growth hormone organic water-soluble fertilizer foliar spray, once a day, for 2 to 3 consecutive days.
2. Biphenyl Acetate Emulsion, Abamectin Emulsion, and Pyridalyl
For chili leaves curling caused by tea yellow mites, it is important to clean the garden to reduce the pest population and strengthen field management. If it is facility cultivation, it is necessary to control the relative humidity inside the room below 80%.
Chemical control should focus on spraying at the early stage of the disease. The available pesticides include biphenyl acetate emulsion, abamectin emulsion, and pyridalyl, sprayed once every 10 days for 2 to 3 consecutive times. When spraying, the focus should be on the upper tender parts of the plant and the back of the leaves.
