Inventarisasi Organisme Pengganggu Tumbuhan pada Tanaman Buah Naga (Hylocereus sp.) di Desa Batuah Kecamatan Loa Janan Kabupaten Kutai Kartanegara

Abstract

Kutai Kartanegara (Kukar) Regency has the potential for vast land, a suitable climate, and the enthusiasm of local farmers as a major dragon fruit producing area in East Kalimantan, even nationally. Batuah Village, Loa Janan Sub-district, is one of the villages with a high number of dragon fruit producers managed by a joint farmer group. The development of dragon fruit is now starting to be constrained by problems in cultivation as well as pests and diseases. Pest attacks can reduce the quality and quantity of crop yields, thus becoming a limiting factor in dragon fruit production. This research aims to inventory pests on dragon fruit plants in Batuah Village. This research was conducted for approximately 1 month, starting from research preparation to final identification in 5 (five) different gardens in Batuah Village, Loa Janan District. Observations were made on dragon fruit plants that were attacked by diseases, pests and nematodes. Based on the results of the research conducted, it can be concluded that dragon fruit plants in Batuah Village are attacked by pests and diseases which are mostly caused by fungi, bacteria and fruit flies. But for bacteria can only be seen based on symptoms and signs, while the nematodes found are non-parasitic nematodes. Fungi that attack dragon fruit plants include Fusarium sp., Phytophthora sp., Pythium sp., Botryodiplodia sp., and Bipolaris sp. The most common fungus found in this study is Fusarium sp. Pests that are commonly found and damage dragon fruit are fruit fly larvae (Bactrocera sp). Non-parasitic nematodes found on dragon fruit plants in this study were Rhabditis sp., Dorylaimus sp., and Aphelenchus sp.
