Abstract
Pesticide residues and metabolites are often found in fruits, vegetables, soil and underground
water as contaminants. This necessitated the search for bio-nematicides, accordingly the nematicidal prospect
of chromatographic fractions from Mangifera indica as a substitute to synthetic nematicides in the control
of Meloidogyne incognita pests of tomato was evaluated. Crude extracts of M. indica bark was fractionated
on silica-gel (120-150 mesh) using glass column. The resulting fractions were investigated in screenhouse
and field trials. The fractions were equated with carbofuran a synthetic nematicide. Each experimental pot
containing 40 kg of pasteurized soil was inoculated with 1000 eggs of M. incognita in the screenhouse, while
2500 eggs was introduced to the base of each tomato plant on the field. Significant (p<0.05) increase was
noted in the vegetative growth of treated tomato plants. Fruit weight per plant and number of fruits per plant
increased notably as opposed to the untreated tomato plants. Nematode population in root and soil of treated
tomato plants also reduced significantly. Terpenes, esters, aldehydes, phenols and ketones were identified as
the major constituents of the fractions with partial characterization. The reduction in nematode population
in the screenhouse and field signifies that fractions from M. indica could be employed in place of the
environmentally undependable synthetic nematicides, while encouraging a sustainable and safe environment
in tomato cultivation
