Control of diseases and insect pests of Clivia nigra

It belongs to the family Amaryllidaceae and is mainly distributed in southern Africa, which is also its place of origin. In Hubei Province and Beijing, it is also widely distributed. At present, with the development of technology, this kind of plant has been introduced and cultivated artificially. Today we will mainly introduce its insect pests and diseases.

Disease

Compared with insect pests, it has more diseases, so we mainly introduce this aspect.

The first disease is called "root rot", which is a disease we are familiar with. It is mainly caused by too much water in the basin or accidentally causing bacteria to invade through the root wound during transplantation. its symptoms may be shown in the leaves, yellowing leaves or not giving birth to new leaves. In view of this disease, first of all, when we transplant, we should pay special attention to the need to cut off these parts if there are festering parts in the root, and apply some on the wound surface to be sterilized. Also, pay attention to the amount of water, do not let the basin soil accumulate too much water.

The second disease is called sunburn, and it can also be inferred from its name that it is caused by excessive light. The disease mainly occurs in summer, when the leaves turn yellow in large areas. For this kind of disease, the solution is relatively simple, which is to shade the plant properly and cut off the yellowing leaves.

The third disease is anthrax, which mainly occurs in the very wet season. To prevent and cure this disease, we can spray some carbendazim. In addition, we should remove and burn the diseased leaves and withered leaves. Also, ventilation and light transmission are also very important.

Insect pest

One of the more common pests is the "soft snail", which eats the leaves of this plant and makes them grow crooked. To deal with this pest, we must first know that they like a humid environment. Therefore, in the dark and damp evening, we can concentrate on hunting, or spray some chemicals to kill.
