Pest control of the latest echinacea

Root rot disease

This disease is relatively common, mainly invading the roots, but we may not be able to find it at this time, and the disease will not be found until the yellow leaves, so the prevention of the disease is very important. This disease is mainly caused by the accumulation of too much water in the soil next to the root. If planted indoors, do not let the water accumulate when watering. Once part of the water is accumulated, it will cause the root in the basin to rot.

If you plant outdoors, if you can't control the amount of water, you must do a lot of drainage work in the rainy season, so as to minimize the occurrence of the disease, and if the disease has already occurred, pull out the diseased plant in time, let the pathogen principle other plants and spray other plants with appropriate agents.

Yellow leaf disease

If you look at the name, you can see that the disease is that the leaves gradually turn yellow, even curl, and the plant will slowly become shorter. If there is no timely treatment, the flowers are also very dark, even deformed, there is no way to appreciate. However, the symptoms of this disease generally appear in the second year of infection, so we must seize the time to prevent and cure it. Carbendazim can be sprayed two or three times a week. If a diseased plant is found, it should be pulled out in time, and then buried or burned, so as not to spread the disease.

Cabbage worm

This kind of worm is also relatively common, once a few are found, it can be removed directly, but if it appears in large numbers, it can be sprayed with cyhalothrin EC, once a week, a total of 2-3 times.
