Efficacy of botanicals on mortality of second stage juveniles and egg hatching of Meloidogyne javanica L: An eco-friendly management approach

Abstract

Root knot nematode is an important pest in many vegetable, fruits and field crops. The extracts of seven different botanicals were tested for their effect on the egg hatching and mortality of Meloidogyne javanica. The results revealed that neem (Azadirachta indica) had the highest inhibitory effect and recorded lowest egg hatching percentage and highest larval mortality. It was followed by Carrissa spinarum (Wild Karonda) root extract. The inhibitory effect of the botanicals on egg hatching and larval mortality was directly proportional to the exposure period and inversely proportional to the concentration.
