Abstract


Aqueous leaf extracts were utilized to assess the nematicidal or nematostatic property on second stage juvenile of Meloidogyne incognita. The juvenile were incubate at various concentration of leaf extract viz., 250, 500, 1000 and 2000 ppm. Corrected mortality using Abbot’s formula was recorded after 12, 24 and 48 hours respectively. Correlation coefficient (Pearson) was checked to explain the association between percentages mortality of juvenile with extract concentrations. Linear regression was used to denote concentration and rank dependent outcome of four aqueous plant leaves extracts on the second stage juvenile (J2) mortality. All leaf extracts were found to be nematicidal or nematostatic in property. Maximum juvenile mortality rate was recorded in Xanthium strumarium throughout the incubation period as followed by Acalypha indica, Argemone mexicana and Colocasia gigantean. Concentration depended effect of X. strumarium and C. gigantean proved maximum and minimum level when analyzed by values of regression and correlation. Aqueous leaves extracts of these aforementioned weeds give us an idea about nematicidal properties and therefore may be used as biopesticide in future.
