Eco friendly management of onion basal rot disease using <em>Trichoderma viride</em> and AM fungi

Author(s):

Abstract:
Four fungal and two bacterial antagonists were screened for their antifungal activity against onion basal rot pathogen <em>Fusarium oxysporumf sp.cepae in vitro</em>. Among these, the fungal antagonist <em>T.viride</em> was highly effective in reducing the mycelial growth and conidial germination by 77.5 and 81.5 per cent respectively. The combined application of <em>T.viride</em> and AM fungi was more effective in suppressing the basal rot incidence than the application of <em>T.viride</em> or AM fungi alone in pot culture under Green house. The results of the four field trials revealed that the coinoculation of <em>T.viride</em> (bulb treatment @ 10g/ kg + soil application @2.5kg/ ha) and AM fungi (soil application @12.5kg/ha) was promising in combating the basal rot incidence and increasing the bulb yield of onion.
