The Severity of Fusarium Wilt Disease in Correlation to the Abundance oxysporum and Phytonematodes: Case Study at Banana Plantation PTPN VIII Parakansalak
 f. sp. cubense is a soil-borne pathogen that infects banana plants causes wilt. Several studies demonstrated phytomatodes have role helping infection pathogens cause This study aims determine relationship between phytonematodes from soil roots infected with fusarium Soil samples was obtained collected based on different scores wilt disease severity. Samples were then composited score, abundance each measured following extraction laboratory. highest population 77 g-1 severity score 4; lowest 16 2. As for root samples, (85 g-1) 0 (33 3. Two species identified, i.e. Helicotylenchus Radopolus Based measurement using conventional methods showed 1, 8.1 × 103 cfu 1.0 soil. effect shows positive 8.3% it may contribute by 0.6%. can wilting bananas without help phytonematode found this study.
