Therefore, once discovered, pesticide should be sprayed immediately for control. As for what pesticide to spray, let us continue to look at pest and disease control for the thick-leaf plant.

2. 4 pest and disease control methods for the thick-leaf plant

1. Scale insects

Although the thick-leaf plant is not prone to getting bugs, when the environment is not well ventilated and care is improper, it can also get scale insects. This insect uses its piercing-sucking mouthparts to suck the sap from leaves and small branches, affecting the plant's normal growth and development. In severe cases, branches or leaves wither and die.

Control method: After discovering a small number of scale insects, they can be gently brushed off with a soft brush and then rinsed clean with water; when there are many scale insects, pesticide must be sprayed. The pesticide can be Kuangshajie at 800-1000 times dilution. Generally, one application can achieve the control effect.

2. Aphids

One of the most common pests of indoor potted plants, it also harms the health of the thick-leaf plant. Aphids mainly harm the tender leaves and stems of the thick-leaf plant. They parasitize on the leaves and suck sap. Once aphids appear, they are densely packed and look very frightening, so protection must be timely.

Control method: When a small number of aphids is found, tools such as a writing brush can be used to brush the insects off; when there are many aphids, related insecticides are needed. The editor recommends using 2.5% rotenone emulsifiable concentrate at 1200 times dilution. After continuous spraying several times, the effect is excellent.

3. Gray mold

This disease mainly invades through weakened host tissues and can harm the plant's stems, leaves, and flowers, especially the flowers. When the leaves and petioles of the thick-leaf plant appear grayish-white, water-soaked, or even softened to the point of rotting, it may be suffering from gray mold.

Control method: When the above symptoms are found, promptly cut off the diseased leaves to reduce the source of infection; in the early stage of the disease, spray 70% thiophanate-methyl wettable powder at 1000 times dilution, or 50% carbendazim wettable powder at 800 to 1000 times dilution for control. Spray once a week, and the effect is excellent after 2 to 3 consecutive sprays.

4. Powdery mildew

Powdery mildew, another disease of the thick-leaf plant, mainly harms leaves, tender stems, flower buds, and flower buds and other parts. Symptoms: many white powdery lesions appear on the leaves of the thick-leaf plant. These lesions greatly affect its photosynthesis, and over time can even cause the plant to die.

Control method: Promptly cut off severely diseased plants or severely diseased parts and burn them together to reduce the source of infection; in the early stage of the disease, spray 50% carbendazim wettable powder at 800 times dilution, 80% zineb at 500 times dilution, or 75% chlorothalonil 500 solution for control. Alternating applications give a better effect.

That is all the editor has to introduce about pest and disease control for the thick-leaf plant. I believe everyone should know what to do when encountering bugs or illness again! In general, the thick-leaf plant is still not prone to getting bugs. As long as everyone cares for it according to the growing methods for the thick-leaf plant, bugs will not come looking for it.
