Last Updated: 2024/11/06, Rhododendron chlorosis is not only a non-infectious disease, but also a common disease in rhododendron cultivation. After the plant has pathological changes, the leaves become thinner, chlorotic and pale, so the disease is also called chlorosis, and the new leaves lack green obviously. When the leaves of the new shoots become lighter and the mesophyll turns yellow, the veins are still green. At this time, the symptom of iron deficiency is generally diagnosed. This phenomenon often occurs in alkaline soil and areas where alkaline water is used to water flowers. After the disease appeared in the leaves, the photosynthesis could not be carried out normally, and when it was light, it affected the growth and hair of the plant.

This phenomenon often occurs in alkaline soil and areas where alkaline water is used to water flowers. After the appearance of diseased leaves, photosynthesis can not be carried out normally, which will affect the growth and development and ornamental value of the plant in light cases, and lead to plant death in severe cases.

Prevention and control measures: to strengthen cultivation management, combined with irrigation, ferrous sulfate solution can be irrigated, and 0.5% ferrous sulfate solution can be sprayed on the leaf surface, which can gradually restore the green leaf surface of the plant.
