Title: Compatibility of Pochonia chlamydosporia with nematicide and neem cake against root-knot nematode, Meloidogyne incognita infesting okra.
Abstract: The effect of antagonistic fungus, Pochonia chlamydosporia, a parasite of nematode eggs, neem cake and carbofuran alone and in combinations were evaluated in micro plots infested with Meloidogyne incognita on okra under net house condition. Plant growth parameters, fruit yield, root galling, egg production and final nematode population densities were determined after 90 days of germination. Heavy galling in the nematode alone treatment was observed resulted in highest root weight as compared to treated ones and healthy. All the treatments receiving any of the management components showed enhancement in plant growth and suppression of nematode multiplication. The effect of P. chlamydosporia (BCA) was recorded better than neem cake and at par with tested nematicide. The combined application of BCA with neem cake and/or carbofuran at reduced doses gave better recovery in comparison to either of the single application in terms of shoot length, shoot weight, root length and fruit yield and significantly (P<0.05) suppressed M. incognita in terms of galling, egg production, and soil population. The trio combination of P. chlamydosporia, carbofuran and neem cake yielded significantly not only higher fresh fruit weight with a recovery of 53% but also recovered shoot weight up to 64% over control and suppressed root-knot disease severity in terms of galling, egg production and nematode population (89%, 90% and 81% respectively) with a marginal difference with dual application BCA and carbofuran.
