Cordyceps javanica IF-1106 is an entomopathogenic fungus with a wide range of hosts. It produces microsclerotia in liquid media. This study took close observation the formation process C. and described surface characteristics microsclerotia. Secondly, viability under high temperature ultraviolet radiation were determined. Thirdly, stored different temperatures to assess storage stability. Finally, activity against root-knot nematode influence on plant growth cucumber investigated. Spores germinate quickly, hyphal elements clump together, forming hydrophobic The have 100% survival 55°C UV-B 3 J cm-2. Following such exposure, are able produce conidia. After 1 year at either room (25°C) or refrigeration (-80°C, -20°C, 4°C), all germinated spore yield was more than 4 × 109 spores g-1. showed ovicidal eggs, glasshouse pot trial indicated that control efficiency nematodes reached 92.6%, which improved test plants. These attributes suggest this can be applied as biocontrol agent soil borne pest nematodes.
