The percentage of attacks by Pestalotiopsis sp in nursery one (f?) is 20%, while the intensity of attacks in nursery one (f?) is 4%, in nursery two (f?) the percentage of attacks is 5%, while the intensity of attacks in nursery two (f?) is 1%, and in nursery three (f?) attack percentage was 20% while the attack intensity in the three (f?) nursery was 4%. From this research, it was concluded that two diseases were found in oil palm seedlings, namely Curvularia sp leaf spot and Pestalotiopsis sp leaf spot.]]>
