Epimedium Disease and Pest Control

Diseases

The first one is "leaf spot disease". As the name suggests, some spots will appear on the leaves when the disease occurs, and they will gradually expand and become larger, forming some irregular large spots. This disease occurs in both the seedling and adult stages, but it is more serious in the seedling stage. To deal with this type of disease, we must first remove the damaged parts and reduce the source of infection. Then spray pesticides for prevention and control. There are many options available, such as Bordeaux agent, carbendazim solution, etc., which can be used alternately to avoid the emergence of drug resistance.

The second disease is called "rust", which mainly threatens the leaves and fruits of this plant. In the early stages of the disease, we will find some inconspicuous small spots, which will turn into raised spots in the later stages. Next, the lesions may burst, causing the leaves to die and the fruit to become dead. To deal with this disease, we can use a 15% solution of triadimefon diluted one thousand to one thousand five hundred times. Another thing is to strengthen management and clean up debris in the surrounding environment in a timely manner.

There is also a "physiological red leaf disease", which mainly occurs in exposed areas without shade. When infected, the leaves turn from green to red, the plant's growth is stunted, and fruit production is reduced. To deal with this disease, what we need to do is take appropriate shading measures.

Pests

There are many pests that can cause harm to this plant, such as wireworms, mole crickets, grubs, etc. To deal with them, if the number is small, you can capture them manually, use poisonous bait to kill insects, or set traps to lure them.
