บทคัดย่อ (EN): Major rubber growing provinces in Mindanao, Philippines (Agusan Sur, Basilan, Bukidnon, Cotabato, Davao, Sarangani, and Zamboanga del Norte, Zamboanga del Sur, and Sibugay) were surveyed for incidence and severity of prevailing diseases. Results of studies showed that there were 20 hosts of Rigidoporus lignosus causing white root rot and 13 of Phytophthora palmivora causing shoot tip blight, black stripe, stem canker, and bark splitting of rubber. Twenty rubber clones were screened against different foliar diseases of rubber under nursery condition. Bird’s eyespot (Helminthosporium heveae), anthracnose leafspot (Colletotrichum gloeosporioides), and leafblight (Phytophthora palmivora). Synthetic fungicides applied as curative against white root rot and black stripe diseases significantly reduced disease severity of rubber trees for six months. Three basidomycetous fungi namely, bracket fungus I (BF1), two wild mushrooms (WM1 & WM2), and T. harzianum can be potential biological control agents against R. lignosus causing white root rot disease of rubber. Furthermore, botanical extracts (Euphorbia heterophylla and Euphorbia hirta) against Helminthosporium heveae causing bird’s eyespot of rubber were significantly comparable to Trichoderma harzianum, which was also comparable to the fungicide or chemical check, Captan. Cultural management may be done by using resistant clones; pruning out diseased leaves and twigs and discarding properly; adequate fertilizer; spacing trees in nursery for good air circulation; brushing newly cut budded seedlings to avoid entry of harmful microorganisms; removing of dead stumps and branches to reduce disease inocula; proper distance of planting; providing canals near infected trees to avoid spread of fungal rhizomorphs; continuous monitoring and weeding must be done to prevent disease spread particularly root rot diseases.
