    • Abstract

       

      With NPK solution as the basic nutrient applied to the root-knot nematode infected cowpea plants, amendments were made with 100 ppm of phenol prepared from alcoholic extract of palmyrah wood sawdust. Further amendments consisted in adding gibberellic acid or indole acetic acid or gibberellic acid+indole acetic acid. Amended nutrient applications reduced galling, fecundity of the pathogen, pathogenic impact, improved root weights and synthesis of metabolites which signified the improved vigour of the infected host.
