Liquid formulations of entomopathogenic fungus, Verticillium lecanii (Zimmermann) Viegas were evaluated against spiralling whitefly, Aleurodicus dispersus Russell at Biocontrol Research Laboratory, Mahatma Phule Krishi Vidyapeeth, Rahuri, during 2002-04. The study revealed that liquid formulation A (VGTA 50512) and B (VGTA 50510-5) of V. lecanii caused 78.33 to 92.34 and 80.20 to 93.45 per cent mortality of the whitefly, respectively. V. lecanii at one per cent concentration gave the highest mortality of 92.34 per cent (Formulation A) and 93.45 per cent (Formulation B) respectively but it was on par with the concentration of 0.45 to 0.75 per cent. So, 0.45 per cent concentration of the liquid formulation is the most economical and feasible concentration for the control of the pest.

Liquid formulations of entomopathogenic fungus, Verticillium lecanii (Zimmermann) Viegas were evaluated against spiralling whitefly, Aleurodicus dispersus Russell at Biocontrol Research Laboratory, Mahatma Phule Krishi Vidyapeeth, Rahuri, during 2002-04. The study revealed that liquid formulation A (VGTA 50512) and B (VGTA 50510-5) of V. lecanii caused 78.33 to 92.34 and 80.20 to 93.45 per cent mortality of the whitefly, respectively. V. lecanii at one per cent concentration gave the highest mortality of 92.34 per cent (Formulation A) and 93.45 per cent (Formulation B) respectively but it was on par with the concentration of 0.45 to 0.75 per cent. So, 0.45 per cent concentration of the liquid formulation is the most economical and feasible concentration for the control of the pest.
