Pemanfaatan Agens Hayati Endofit untuk Mengendalikan Penyakit Kuning pada Tanaman Lada

Rita Harni, Abdul Munif

Abstract


Penyakit kuning merupakan penyakit penting pada tanaman lada di Indonesia. Kerugian akibat serangan penyakit kuning dapat menurunkan produksi sampai 32%. Penelitian ini bertujuan mengevaluasi pengaruh penggunaan agens hayati dari kelompok bakteri dan jamur endofit untuk mengendalikan penyakit kuning yang disebabkan oleh Meloidogyne incognita, Radopholus similis pada tanaman lada. Penelitian dilakukan di kebun lada petani di daerah Petaling, Bangka. Bakteri endofit yang digunakan merupakan isolat endofit yang diisolasi dari akar tanaman lada dan beberapa isolat bakteri dan jamur endofit koleksi yang potensinya telah diuji. Percobaan menggunakan rancangan acak kelompok (RAK) 7 perlakuan dengan 5 ulangan. Tanaman lada percobaan berumur 15 bulan diperlakukan dengan isolat endofit (MER7, AA2, ANIC, TT2, dan TRI) dan nematisida karbofuran digunakan sebagai pembanding. Hasil penelitian menunjukkan bahwa perlakuan agens hayati endofit dapat menekan kejadian penyakit kuning dan populasi nematoda di dalam akar.  Selain itu perlakuan agens hayati endofit dapat meningkatkan jumlah bunga per ruas dan bobot basah lada pada panen I. Isolat yang paling potensial adalah ANIC dan TRI (Trichoderma), yang keefektifannya sama dengan nematisida kimia karbofuran.

 

The Use of Endophytic Biological Agents to Control of Yellow Disease in Black Pepper

ABSTRACT

There are increasingly efforts to control the yellow disease in black pepper through application of biological agents endophytic along with the dangers of pesticide uses and awareness of environmentally friendly agriculture. The objective of this study was to investigate the effect of endophytic biological agents (bacteria and fungi) on the disease caused by nematodes of M. incognita and R. smilis. The study was conducted on the farmer garden located at Petaling, Bangka. A randomized complete block design with 7 treatments and 5 replications was used in this study.  The black peppers were treated with endophytic isolates (MER7, AA2, ANIC, TT2, TRI) and carbofuran, chemical nematicide, as control (not treated). The endophytic agents used in this study were isolated from roots of black pepper and some selected endophytic collections. The results showed that some endophytic agents were able to suppress the incidence of yellow disease and nematode populations in the roots, and increase in the number of flowers and fresh weight of  black pepper berry. The promising isolates being able to control the disease are ANIC and TRI (Trichoderma) on which their effectiveness are similar to the carbofuran.
