| Abstract | ||
| Three antagonisitc fungi reduced the percentage of egg hatching and larvae activity compared to control treatment under laboratory conditions . The antagonistic fungi were Paecilomyces lilacinus, Trichoderma harzianum and Epicoccum sp. Significant reduction was observed in the viability of larvae of root - knot nematode when two different antagonsitic fungi were conbined as compared to treatments whith single biocontrol agents. These three different fungi were used under green-house and field conditions. Although there was a clear and significant difference in the effect of different antagonistic fungi under green-house conditions there was no differrence between Paecilomyces and Epicoccum under field conditions. Significant reduction in disease incidence or root-knot. index were observed where the rate of application of antagomisits was increased from one gram / pot to two grams / pot . On the other hand, no significant difference was observed between two grams / pot and three grams / pot for Paecilomyces and Trichoderma. Paecilomyces Illacinmus proved to be a good biocontrol agane in reducing the disease incidence or suppressing root - knot index. It also retarded egg hatching and reduced the viability of larvae, if it was used alone or with other antagonistic fungi in green - house and field conditions as compared to the control . | ||
