Identification of Pest and Disease in The Plant Conservation Center - Bogor Botanical Garden (PKT-KRB) Ecological Park Cibinong, Bogor, West Java, Indonesia

Abstract

The purpose of this study were: (1) to determine the pests and diseases infestation of plants in the Plant Conservation Center - Bogor Botanical Garden (PKT-KRB) Ecological Park area in Cibonong, Bogor Regency, (2) to determine the extent of damage that has been attacked by the pests and diseases. Sampling method was made by creating sample plots of 20m x 50m size with sampling intensity of 10% in the selected area at bioregion of Sumatera and of Kalimantan. The result of study showed that plants damage in those areas were dominated by hollow leaves caused by caterpillar pests i.e. at bioregion of Sumatera (37,84%) and of Kalimantan (40,23%). In addition, it was found that the secondly dominated infestation was alga leaf spot (Cephaleuro virescens) that has caused spots on leaf. Infestation intensity of the disease was of 35,14% at bioregion of Sumatra and of 28.74% at of Kalimantan, while the intensity of plants damage at bioregion of both were 36.00% and 42.44%, respectively. The scale of damage in both bioregions was included as score 2, which was the mediun category (⩾26-50%).
