Spider Mites: Spider mites typically infest Polyactium radulifolium Eckl. & Zeyh. during dry and hot weather conditions. They suck the sap from the plant leaves, causing yellowing and shedding of leaves. Managing spider mites involves using insecticidal soap or neem oil and increasing the plant's humidity.
Scale Insects: Scale insects are harmful pests that cause wilting and yellowing of leaves. They secrete a sticky substance called honeydew that attracts ants. To manage scale insects, remove them using a sharp tool or by hand and spray insecticidal soap on the infected plant parts.
In conclusion, managing diseases and pests in Polyactium radulifolium Eckl. & Zeyh. requires regular care and monitoring. Prevention measures such as using well-draining soil, avoiding overwatering, and maintaining proper humidity can help control disease and pest infestation.
