Reasons for Chili Leaf Curling and Remedial Methods
Article Abstract: For the content about chili leaf curling reasons and remedial methods in the green plant and flower aspect, please refer to the detailed introduction below.
Reasons for Chili Leaf Curling and Remedial Methods
Chili leaf curling may be caused by a lack of microelements such as iron and manganese in the soil, insufficient watering during the growth period, or excessive application of nitrogen fertilizer. It is necessary to water promptly, ensure good drainage after rain, and fertilize moderately, especially avoiding excessive nitrogen fertilizer. If the plant has already wilted, it is necessary to spray medication.
What Causes Chili Leaf Curling
Chili leaf curling may be due to long-term low temperature and high humidity in the seedbed, leading to poor plant growth, yellowing leaves, and curling of the top leaves, as well as rotting of the root system.
If chili plants show leaf curling and falling, it may be due to a viral disease causing yellowing, which is caused by long-term water deficiency or waterlogging, or excessive application of nitrogen fertilizer during the growth period, leading to yellowing and falling of the leaves.
Reasons for Chili Leaf Curling
Chili leaf curling may be due to a lack of microelements such as iron and manganese in the soil, and insufficient watering during the growth period, leading to leaf drying and curling of the lower leaves. It may also be due to excessive application of nitrogen fertilizer, causing the small leaves to curl.
If the newly grown chili leaves are curling, it is mainly because of high temperature or too much light intensity, leading to severe water deficiency inside the plant and resulting in leaf curling. This situation occurs more frequently in summer.
Remedial Methods for Chili Leaf Curling and Withering
For chili leaf curling, it is necessary to water promptly but avoid waterlogging, ensure timely drainage after rain, and fertilize moderately, especially avoiding excessive nitrogen fertilizer. If the plant has already wilted, it is necessary to spray medication and also consider planting varieties that are resistant to toxicity.
If chili plants suffer from wilt disease, the leaves will gradually turn yellow from the bottom up and drop in large numbers, and the stems and leaves will quickly wither and die. Waterlogging in chili fields and excessive use of nitrogen fertilizer can cause chili plants to suffer from wilt disease. Therefore, it is best to plant chili in areas with convenient drainage and irrigation. After getting the disease, the plants can be sprayed with a 800-fold solution of potassium permanganate, three times in a row.
Chili leaves curling and turning yellow
May be due to excessive watering, where the soil easily has积水, hindering the roots from breathing, which will cause yellow leaves. Watering should be reduced in amount and frequency, and make sure not to have waterlogging. If it is due to insufficient nutrients, the old leaves will turn yellow, and top dressing should be done in time, using compound fertilizer. If yellowing is due to lack of sunlight, supplemental lighting is needed to let the plant get more sun.
Chili leaves curling with pests
When pest damage has already occurred, the affected branches and leaves should be pruned and incinerated, then sprayed with a 10% emulsifiable concentrate of oxidized ricinoleic acid at a 900-fold dilution or with imidacloprid solution. Spray every two weeks for three times to effectively solve the problem.
