What are the pest and disease control methods for the Aglaonema 'Ruyi Queen'?

Diseases

A disease called "viral disease" is fairly common and can harm the growth of the Aglaonema 'Ruyi Queen'. When it strikes, some irregular spots appear on the plant's leaves, usually yellow in color. At the same time, the leaves become deformed and curled or wrinkled, and in severe cases they may even become misshapen. If this continues, the entire plant will show stunted growth and eventually die.

To control this disease, we can first spray some chemicals, such as 5% beta-cypermethrin at a 3000-fold dilution; this solution is fairly effective against the disease. In addition, we can apply a bit more flower fertilizer rich in the K element and the P element to increase its resistance to disease.

In addition, attention should be paid to "root rot". This disease occurs frequently from May to October. Its cause is that during the rainy season there is too much water accumulated in the soil, which leads to the roots rotting, and then the plant's leaves also wither, and it spreads very quickly. To deal with this disease, we first have to dispose of the diseased plants. Also, we can spray the corresponding chemicals. Then, be sure to drain the water promptly during the summer rainy season.

Pests

The pest that occurs fairly often is a pest called the "red hawk moth". Their larvae are extremely harmful to this plant. They gnaw on the plant's leaves, creating holes. The pest infestation occurs more often in July and August. To deal with this insect, we can spray trichlorfon at an 800-fold dilution to kill the pest's larvae, and facts have proven that this works well.
