ABSTRACT
Present study reveals that V.lecanii strains were isolated from different crop rhizospheres and were purified where the cultures obtained were designated by denoting crop and location from where they were collected. A total of 6 isolates viz., BCSH VSF CF (sunflower), BCSH VM CF (maize), BCSH VGN FF (ground nut), BCSH VRG SF (redgram), BCSH VJ AF ( jowar)and BCSH VT AF (tomato) were evaluated for their biological attributes along with PDBC isolate as standard check and lab culture as local check for comparision. Among the test isolates, BCSH VT AF from tomato rhizosphere showed maximum radial growth (59.17 mm), highest conidial concentration (1.58 x109), highest percentage of conidial viability (94.24 per cent). Findings of the present investigation shared strain variation among the isolates collected from different crop rhizospheres.
Key words: Isolates, Biological attributes, Verticillium lecanii.
