Abstract:
A field experiment was conducted during kharif, 2016-17 to 2017-18 in experimental farm situated at Tirhut College of Agriculture, Dholi, Muzaffarpur, Bihar to evaluate efficacy of Salicylic acid on the incidence of Maydis leaf blight and grain yield of maize. The result indicated that all the treatments were found effective as compared to untreated check. Lowest PDI of Maydis leaf blight disease (35.0), maximum percent disease control (61.11%), maximum grain yield (40.44 q/h) and maximum percent increase in yield (18.29%) were recorded in Salicylic acid (SA) @ 200 mg/ liter as foliar spray before 24 hrs. inoculation followed by Salicylic acid (SA) @ 150 mg/ liter as foliar spray before 24 hrs. inoculation. No toxic synergetic effect could be observed on germination.
