Abstract
Abstract Pot experiments laid out in a complete randomised design were conducted in the screen house of the Department of Crop Protection, University of Agriculture, Abeokuta, Ogun State, Nigeria to determine the effects of organic fertiliser and Chromolaena odorata residue at 1% w/w on the pathogenicity of Meloidogyne incognita infecting maize. M. incognita significantly reduced the plant height, number of leaves per plant, leaf area, cob weight and grain yield of maize by 6.89, 15.18, 20, 63.92 and 56.16% respectively. C. odorata residue and organic fertiliser significantly suppressed M. incognita galling, inhibited the nematode fecundity and reduced the number of eggs and juveniles on maize. A remarkable increase in plant height, number of leaves per plant, leaf area, cob weight and grain yield were observed on maize plants treated with the mixture of C. odorata and organic fertiliser despite the nematode infection. The observation from this study suggests that C. odorata in combination with organic fertiliser is a viable option for the control of M. incognita on maize.
