Untuk memaksimalkan potensi lahan dan meningkatkan pendapatan petani maka dilakukan diversifikasi tanaman kelapa dengan memanfaatkan lahan di bawah kelapa dengan tanaman kakao. Ditinjau dari aspek penyakit tanaman, hal ini mengkuatirkan karena tanaman kelapa dan kakao memiliki penyakit penting yang disebabkan oleh patogen yang sama Phytophthora palmivora. Patogen tersebut patogen menyebabkan penyakit gugur buah pada tanaman kelapa dan penyakit busuk buah pada tanaman kakaoyang sangat merugikan.

This study was conducted to differentiate the isolates of P. palmivora from coconut and cocoa pod based on morphology and molecular characters, diversity, virulence and cross inoculation. Comparative morphological : diameter of colony, length and width of sporangium, l/w ratio , type of colony and sequence ITS-DNA tes ts showed that all isolates of Phytophthora isolated from coconut and cocoa in Indonesia are Phytophthora palmivora. Morphological characters of pathogen isolated from cocoa were smaller and significantly different in length, width, length/width ratio of sporangium and diameter of colony compared to isolates from coconut
