Abstract
Among the extracts tested, garlic clove extract was highly effective in inhibiting the growth of
Helminthosporium maydis as it produced 66.5, 73.8 and 83.9% growth inhibition at 2, 5 and 10%
concentrations, respectively. Neem leaf and tulsi leaf extracts were found effective as growth
inhibitions were between 37 to 65 and 39 to 48 %. Bael leaf extract was not at all inhibitory even
at 10% concentration. Similarly, onion bulb and mentha leaf extracts were also not very promising
as they produced only 38.6 and 25.4% inhibition, respectively at 10 % concentration. The disease
was adequately managed by spraying of garlic and neem extract @ 5% in fields
