However, even such a beautiful plant can be troubled by diseases and pests. Here are some common diseases and pests of Kalanchoe daigremontiana and their control methods.
Aphids: Aphids are common pests that suck the sap of plants, causing leaf deformation and growth inhibition. Control methods include rinsing the plant with water or using biological control methods, such as introducing ladybugs as natural enemies.
Spider mites: Spider mites prefer dry environments and feed on the underside of leaves, causing yellow spots or leaf drying. Spider mite control can be achieved by increasing air humidity, using miticides, or manually removing them.
Root rot: Kalanchoe daigremontiana may suffer from root rot due to overwatering or poor soil drainage. To control root rot, it is necessary to improve soil drainage, reduce watering frequency, and use fungicides if necessary.
Anthracnose: This is a fungal disease that causes black spots on leaves. Control of anthracnose can be achieved by improving ventilation, reducing humidity, and using fungicides.
—— disease: —— disease causes a white powdery layer on the leaf surface, affecting photosynthesis. Control of —— disease can be achieved by using sulfur powder or specialized fungicides.
Grey mold: Grey mold usually occurs in humid environments and forms a gray mold layer on leaves. Control of grey mold requires keeping the environment dry, promptly removing diseased leaves, and using fungicides.
Scale insects: Scale insects attach to the plant surface, suck sap, and cause leaf yellowing. Control of scale insects can be achieved by wiping with alcohol or using insecticides.
Black spot disease: Black spot disease, caused by fungi, causes black spots on leaves. Control of black spot disease requires keeping the plant dry, using fungicides, and promptly removing diseased leaves.
Nematodes: Nematodes can infect plant roots, causing root damage. Control of nematodes can be achieved by using nematicides or disinfecting the soil before planting.
Environmental management: In addition to the specific pest and disease control methods mentioned above, good environmental management is also key to preventing diseases and pests. This includes maintaining appropriate temperature and humidity, ensuring good ventilation, regularly cleaning withered and diseased leaves, and reasonable fertilization.
