CONCOMITANT INFLUENCE OF HYDROGEN PEROXIDE, WATER TEMPERATURE GRADIENT AND ROOT PROCESSING METHOD ON BURROWING NEMATODE EGRESS FROM BANANA ROOTS

Rashid M. Khan, P. Parvatha Reddy

Abstract


Splitting of banana roots and their incubation at 25 °C (±2 °C) in plain tap water yielded a significantly higher and physiologically active population of Radopholus similis. Conversely, split root incubation in hydrogen peroxide (20 ml/lit) at 20 °C yielded a higher population as compared to split root incubation at 20 °C in tap water. By and large root splitting had a positive influence on nematode egress from roots compared to unsplit roots.
