ABSTRACT
This research determined the efficacy of neem leaves ectract as nematicide on root-knot nematode, Mellodogyne sp. Five samples with two replicated each were prepared with equal number of root-knot nematodes from gallsfound in okra roots. Samples were treated with five extract concentrations (100%, 75%, 50%, 25%, 0%).
Observations at 96 hours after the treatment showed that the highest number in percentage of live larvae is 79.59% from 100% from neem leaves extract and the lowest larval count is in thecontrol sample ( Plain distilled water ) with 11.84%.
The researchers concluded that the neem leaves extracts does not affect the root-knot ematodes as a nematicie, rather the chemical component of the extract from neem leaves seemingly persevered and lengthen the life of the nematodes.
