Effectivity of the Consortium of Rhizobacteria and Endophytic Bacteria to Controls the White Tip Disease of Rice Caused by Seed-Borne Nematode Aphelenchoides besseyi

<p>Aphelenchoides besseyi is a seed-borne nematode that causes white-tip disease in rice. Yield losses due to this infection reach 30-50% various countries. This research aimed investigate the effectiveness of consortium rhizobacteria and endophytic bacteria controlling white tip while promoting growth rice seeds infected by A. besseyi. The experiments conducted were bacterial compatibility test, vitro test examine nematicidal activity consortium, an vivo suppress occurrence promote was at Plant Protection Laboratory, Faculty Agriculture, University Jember from July 2020 December 2020. used randomized block design with five concentration levels suspension 20%, 40%, 60%, 80%, 100%. results showed effectively controlled up 80% compared control. Furthermore, percentage symptoms control plant reached 83%. In comparison, it observed lower range 74.5% 25% plants treated consortium. plant’s symptom length 3.94 cm, average ranged 3.41 cm 1.50 cm. application also found accelerate increasing height root plant.
