Abstract:
The present study was investigated to know the efficacy of different biocontrol agents collected from different districts of Karnataka from maize rhizosphere and non rhizosphere soil. Totally ninety antagonists were isolated and screened under in-vitro against Fusarium solani by using dual culture technique. Among forty three fungal and forty seven bacterial antagonists screened against F. solani, the percent inhibition was varied from 21.73 to 91.37, with a mean of 60.48. The results obtained were highly significant between the different Trichoderma, Pseudomonas and Bacillus strains tested and also over control. Maximum percent inhibition of 91.37 was observed in NT10 followed by NT19 (88.83percent) and RT16 (86.11). Least inhibition of 21.73 percent was observed in NB1 followed by RB1 (24.70). Among the ninety strains tested, all most all isolates inhibited the mycelial growth to an extent of 75.00 percent or more.
