Solution
The correct option is D Paecilomyces lilacinus
Purpureocillium can be isolated from a wide range of habitats including cultivated and uncultivated soils, forests, grassland, deserts, estuarine sediments and sewage sludge and insects. It has also been found in nematode eggs, and occasionally from females of root-knot and cyst nematodes. In addition, it has frequently been detected in the rhizosphere of many crops. P. lilacinum has shown promising results for use as a biocontrol agent to control the growth of destructive root-knot nematodes.
