Response of Pratylenchus spp Infected Tomato (Lycopersicon esculentum Mill) to Organic Compounds from Mangifera indica

open access: yesEthiopian Journal of Environmental Studies and Management, 2015
The need to reduce the negative impact of synthetic nematicides on the environment necessitated the search for bio-pesticides. This study was conducted to evaluate the nematicidal potential of chromatographic fractions from Mangifera indica on tomato in the screenhouse and field. M. indica bark was extracted with ethanol (EtOH) and dichloromethane (DCM)
