Effect of storage of botanical extracts and modified Panchagavya against radial growth of Fusarium oxysporum

Abstract

Storage of botanical extracts reduced the effectiveness on the radial growth of Fusarium oxysporum but enhances in the case of Modified Panchagavya (MPG). The mean radial growth of F. oxysporum at 0, 2, 4, 6, 8 and 10 days of storage were 38.83, 42.68, 46.61, 51.07, 56.04 and 60.73 per cent respectively. Garlic extract showed no growth at 0 day of storage but 10.00 mm was observed at two days of storage period which increased with an increase in storage time and the highest growth of 52.50 mm with 69.84 per cent radial growth inhibition at 10 days of storage period. In case of MPG maximum radial growth of fungal mycelium (57.33 mm) was observed at 0 day storage time and it gradually decreased with increase in storage time where highest growth inhibition was observed at 10 days of storage (42.50 mm) with 52.77 per cent radial growth inhibition of F. oxysporum over the untreated control.
