But there will be the phenomenon of eggplant wilting when planting, how to solve it? Let's take a look.

1. Verticillium wilt of eggplant

Eggplant Verticillium dahliae is a common disease in the process of eggplant planting, and it is also difficult to treat. The main causes of eggplant Verticillium dahliae are low temperature and high humidity, rainfall, improper fertilization and so on. The seedlings will be infected by pathogens. At the initial stage of the disease, green spots will appear between the leaf edges and veins of eggplant, then gradually turn yellow, and finally turn dark brown, until the leaves die. In the initial stage of the disease, eggplant will not always maintain a withered state, but only appear at noon, sooner or later will return to normal, but in the later stage when the disease aggravates, it will not be able to return to normal.

2. Eggplant Fusarium wilt

Similar to Verticillium wilt, it is also a common disease in eggplant production, but the infection rate is low in the seedling stage and usually occurs only after planting. The symptoms are similar to that of Verticillium wilt, in which the leaf margin and veins turn yellow, and then half of the leaves turn yellow until all the positive leaves turn yellow and wither. In the early stage, it also appears at high temperature, and it will return to normal sooner or later, and the diseased leaves turn brown in the later stage, until they wither and fall off, leaving only the stem.

3. Eggplant root rot

The disease is similar to the first two, for example, in the early stage of the disease, the leaves will slowly turn yellow, wither during the day, return to normal sooner or later, and gradually turn yellow in the later stage. But unlike the former two, when the disease is serious, the primary root and branch root epidermis will turn brown, and the cortex will show a state of decay.

4. Prevention and control methods

Although the symptoms of the three kinds of yellowing are different, the control methods are more or less the same, which can be intensified in the eggplant seedling stage, which can not avoid the disease and increase the yield. The symptom is reasonable rotation, and it can also avoid the occurrence of disease. the use of pot seedlings can also help eggplant to avoid diseases and improve the yield. After the eggplant disease occurs, most of it is related to fertilization, so it is necessary to master the correct fertilization method, reasonable fertilization, can also help eggplant effectively avoid withering Yan.
