Abstract

Effect of some adjuvant combinations on the growth of Verticillium lecanii (Zimmermann) Viegas in culture medium and the subsequent infection of Maconellicoccus hirsutus (Green) were evaluated at Mahatma Phule Krishi Vidyapeeth, Rahuri, Maharashtra, during 2002-04. The treatment including V. l. + glycerol (8%) + Tween 80 (1%) + arachid oil (5%) proved to be the most promising, recording maximum surface coverage (92.00%) and biomass (32.10g) at 10 days of inoculation and bioefficacy at 14 days. However, it was on par with the formulations containing V. l. + glycerol 5% + Tween 80 1% + arachid oil 2% and V. l. + glycerol 2% + Tween 80 1% + arachid oil 0.5%. In terms of viability and virulence, V. l. + glycerol 2% + Tween 80 1% + arachid oil 0.5% and V. l. + glycerol 5% + Tween 80 1% + arachid oil 2% emerged as the best combinations.
