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.
