 ABSTRACT

For eco friendly, cost effective and non phytotoxic management eight phytoextracts were tested against black mold (Aspergillus niger) of onion under in vitro condition. Out of eight phytoextracts, maximum inhibition 71.19 per cent was found in Lawsonia inermis which followed by Ocimum sanctum leaf extract (62.97%), Zingiber officinale rhizome extract (62.26%) and Lantana camera leaf extract (61.59%). Minimum inhibition of test fungus was recorded in Jetropha curcas leaf extract (53.20%). Among the six biocontrol agents, Tricoderma viride isolate 6 significantly reduced the growth (78.63%) of test fungus followed by the isolate T. viride isolate-9 with (75.51%) growth inhibition, while least antagonism (61.27%) was obtained with biocontrol agent Basillus subtilis.

Key words: Onion, Black mold, Aspergillus niger, Phytoextracts, Biocontrol agents.
