IV. PATHOGEN INOCULATION
Artificial inoculation of the pathogen E. turcicum was done on 30 days old maize plants and further field was inoculated thrice at 2 day interval. To create high disease pressure the spore suspension was sprayed with an automizer in the late evening. To maintain high relative humidity the plots were irrigated frequently.
V. IMPOSITION OF TREATMENTS
All the treatments were imposed with the appearance of initial symptoms on the 40 day old plants. The second spray of treatment was done 10 days later i.e., at 50 days stage of the crop. The data on per cent disease index was calculated 10 days after the second spray
