On severely infected plants, lesions can become so numerous that the leaves are eventually destroyed.
Late in the season, plants may look like they have been killed by an early frost.
Genotype C-15 recorded significantly higher per cent loss in 1000 grain weight (23.12) followed by Bio 9262 white (21.20).
In vitro studies revealed that Trichoderma harzianum (bio agent), Datura stramonium (leaf extract), Propiconazole (systemic) and mancozeb (non systemic) were most effective in inhibiting mycelial growth of E. In field studies, Propiconazole showed maximum disease inhibition and this treatment was at par with integrated treatment comprising of mancozeb (seed treatment) @ 0.25%, Trichoderma harzianum (s.t) followed by foliar sprays of Datura stramonium extract (50%) and mancozeb (f.s) which showed minimum disease incidence intensity (16.16%) coupled with maximum yield of 39.52 q ha-1.
The colour of colonies ranged from olivaceous grey to olivaceous brown with light black, dark greyish black, dark brown, and blackish growth at centre.
The number of septation in isolates ranged from 1 to 9 and spore size ranged from 71.8×21.2 to 121.5×21.1.
Sporulation requires a 14-hour dew period between 20 and 25 °C (77 °F).
When there is not a sufficiently long period of continuous humidity, the fungus will stop making spores and resume conidia production only when humidity level rises again.
