Abstract

Study was conducted to investigate the effect of oxidation and bromination of fresh and decomposed orange peels

on the nematicidal potential of orange peel oil against Pratylenchus penetrans. Results showed that the

oxidised/brominated orange peel oils were significantly effective at (p ≤ 0.05) than ordinary orange peel oils and

compared with the standard mocap. The decomposed orange peel oil was effective than the fresh peel oil and

showed 51.42% mortality as compared to 39.38% after 24 hrs. Plants received brominated/oxidised oils were taller

with better yields than untreated and nematode infested plots in the field. The GC/MS result indicated that the major

constituents of the orange peel oils were limonene, octanal and citroneloll.
