How to prevent and control pests and diseases of the golden-veined Aphelandra?

Diseases

The most important disease that can harm this plant is "black spot", and we can roughly infer its harm from the name of this disease. When it first appears, some brown or nearly black small spots appear on the leaves of the flower, and their shape is rather irregular. If the condition continues to worsen, then these spots will spread and eventually merge into one, forming large round spots, and the color will also turn completely black.

To prevent and control this disease, first we must cut off the affected leaves, foliage and branches, and dispose of them together, preferably by burning them all. Next, we can spray 75 percent chlorothalonil at 800 times the solution for prevention and control, and this works well. In addition, in the subsequent care we must also pay special attention to ventilation, because this can effectively reduce the incidence of this disease.

Pests

The first pest is called "scale insect". This pest often appears in groups and has a very large impact on plants, which may cause spots on the leaves, and in severe cases may cause the leaves to fall off. To deal with this insect, we can spray avermectin at 2,000 times the solution. In addition, we should also pay attention to ventilation.

The second pest is called "red spider mite", and this pest is also relatively familiar to us. They often gather on the petioles or the undersides of the leaves. To prevent and control this pest, we can spray omethoate at a concentration of 40 percent, 1,000 to 1,500 times the solution. In addition, just like the above pests and diseases, we also need to ventilate regularly.
