Inhibitory Effects of the Leaf Extract of Mitracarpus villosus on Egg Hatch of Meloidogyne incognita at Different Concentrations

Abstract

This study was conducted to evaluate the nematicidal potential of Mitracarpus villosus in controlling the egg hatch and mortality of rook-knot nematode, Meloidogyne incognita. Four different concentration levels of crude leaf extract of M.villosus in distilled water were replicated four times in a completely Randomized Design. Significant differences were observed among the treatments from 6 hours to the 96hours of observation, but there was no significant difference (P≤0.05) between S1 (100%) and S2 (50%) concentration at 3hours, while S3 (10%), S4 (1%) of the crude extract and S5 (distilled water) were significantly different. On larval mortality, the egg that hatched into larvae after 96hours, there were significant difference between S1, S2 and S3, S4 and S5 throughout the period of observation.
