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.
