Eggplant Leaves Curling? Detailed Guide to Prevention and Treatment

During the growth period, eggplant may develop leaf curling due to factors such as temperature, humidity, insect pests, and diseases, and in severe cases it can lead to plant death. So what should you do when eggplant leaves curl?

Cause 1: Lack of trace elements such as boron fertilizer and calcium fertilizer

Eggplant growth absolutely requires some trace elements, and when these are lacking, the plant will show corresponding abnormal reactions. For example, a lack of boron and calcium elements will cause leaf curling, and this kind of leaf curling caused by nutrient deficiency is also a physiological disease. Growth imbalance will lead to leaf curling.

Solution: It is best to use some boron fertilizer and calcium fertilizer together during the eggplant seedling stage, and foliar spraying can also be done later. It can also be sprayed after leaf curling occurs, and it will improve after a period of time.

Cause 2: Temperature and humidity too high

The later stage of eggplant growth happens to be summer. At this time, when temperatures are high, there is also a lot of rain. Under high temperature and high humidity, insect pests and diseases mainly occur, affecting plant growth.

Solution: It is best to plant on slightly higher sloped land, with an appropriate planting density, not too dense, so that field humidity will be greatly reduced. Drought and high temperatures will be higher, so there must be a water source for timely irrigation.

Cause 3: Viral disease

After eggplant is infected with viral disease, leaf curling will also occur, but in addition to leaf curling there are also some wrinkling and plant stunting phenomena, which are relatively easy to distinguish and identify.

Solution: Once it is confirmed to be viral disease, you can promptly purchase corresponding biological pesticide agents for use, to avoid the plant withering after the disease becomes severe. It is best to treat it in time; otherwise, after field farming operations cause sap friction, the disease will spread.

Cause 4: Tea yellow mite

This kind of mite commonly damages eggplant, mainly gathering at the position of the calyx to suck eggplant sap, and finally spots and yellowing appear. Severely damaged leaves will curl, mainly curling toward the back of the leaf, which can be identified. Sometimes the leaves become severely distorted and deformed, and sometimes it is also easy to confuse, so careful observation is needed.

Solution: At the peak of occurrence, in the later stage of eggplant growth, you can use an 80% avermectin emulsifiable concentrate 3000-fold solution or a 3% propargite emulsifiable concentrate 2500-fold solution diluted with water and spray it.
