Effect of fungal filtrates of Fmurium oxyosporium and Aspergillus flavus on Meloidogyne javanica in Okra plant under greenhouse conditions.

摘要

The aim of this study was to test the efficiency of fungal filtrates from Fusarium oxyosporium and Aspergillus flavus in the control of root-knot nematode in laboratory and field .The fungus had been grown on PDA medium and the nematode had been isolated from infection okra plant to prepare nematode suspension and test four concentration of fungal filtrates (25%,50%,75%,100%) on both the nematode and the plant. The effect of concentrations of fungal filtrates showed that, the concentration 25% was the least affected on the nematodes while concentration 100% was the best in reducing the number of nematodes and supporting plant growth. We concluded from this study that the time required to kill all nematode was reduced by increasing the concentration of filtrate and the fungal filtrates have had the capability to support plant growth and reduce number of knot nematode count.
