Biological control of Meloidogyne incognita race 3 and Macrophomina phaseolina by Paecilomyces lilacinus and Bacillus subtilis alone and in combination on chickpea

Summary - Paecilomyces lilacinus and Bacil/us sublilis were used for the biocontrol of the root-rot disease complex of chickpea caused by Meloidogyne incognila race 3 and Maaoplwmina pJwseolina. Individually, P. li/acinus treatment was berrer against M. incognila while B. sublilis against M. pJwseolina. The combined inoculation of P. li/acinus and B. sublilis improved dry shoot weight significantly when plants were simultaneously inoculated either with M. incognila or M. pJwseolina or with both. Resume - Controle de Meloidogyne incognita race 3 et de Macrophomina phaseoli sur pois chiche par Paecilomyces lilacin.ls et Bacillus subtilis, seuls ou en cmnbinaison - Paecilomyces lllaclilus et B(uil/us subLilis sont utilises en vue du controle biologique d'une pourriture racinaire complexe du pois chiche causee par Meloidogyne incognila race 3 et Maerophomina phaseoli. Employes seuls, Paecilomyces li/acinus est meilleur contre Meloidogyne incognila et Baci/lus subtilis contre Macrophomina pJwseo/i. L'inoculation combinee de Paecilomyces liuu:inus et de Bacil/us subtilis augmente de facon significative le poids sec des racines lorsque les plantes sont inoculees, au meme moment, par Meloidogyne incogniz.a et MaeroplwminapJwseo!l~ seuls ou en combinaison.
