What is the reason why the leaves of broad beans curl?

Vicia faba leaves curl, which may be caused by high drug concentration, improper water and nutrients provided for them during maintenance, resulting in fat damage and water shortage of Vicia faba, or the plants are exposed to strong light during growth, resulting in rapid water loss and curling of leaves.

Why broad bean leaves curl 1, and the drug is not used properly.

Broad beans should be sprayed with pesticides regularly during maintenance to avoid pests and diseases. However, in the process of using pesticides, if the pesticides are not diluted according to the packaging dose or sprayed too much, it will lead to phytotoxicity of broad beans and leaf curl. At this time, it is necessary to spray water on broad beans to dilute pesticides.

2. excessive fertilization

Although broad beans are suitable for growing in a fertile environment, frequent fertilizer supply will lead to fertilizer damage to plants, and leaves will curl and cannot grow normally. Therefore, it is necessary to fertilize broad beans every other month in the later maintenance and every ten days in the peak season of broad beans growth, so that plants can grow better.

3. The light is too strong

Broad beans have a great demand for light during their growth. However, when placed in strong light for a long time, the water in plant leaves will be lost too quickly, leading to leaf curl. Therefore, during maintenance, they can be provided with all-day sunshine, and when the light is too strong, they also need shade.

4. Too little watering

Broad beans are suitable for growing in humid environment. In the process of maintenance, too little water is provided to them, which will lead to water shortage and curly leaves. Therefore, in the later period of maintenance, the broad beans should be watered in time when the soil is dry, and the water should be suspended when the soil is wet to ventilate the plants.
