| dc.description.abstract | Sunflower crop suffers from many diseases of which Alternaria blight has been considered as a potentially destructive disease. In vitro evaluation of plant defense inducers revealed that maximum inhibition of A. helianthi was recorded in salicylic acid at 200 ppm (43.79%) followed by monopotassium phosphate at 200 ppm (40.34%). In field conditions, seed treatment followed by foliar spray of salicylic acid at 100 ppm at 30 and 45 DAS increased the growth parameters like plant height (215.46cm), stem girth (3.54 cm), number of leaves (38.43) and chlorophyll content (48.53). Seed treatment followed by foliar spray of salicylic acid at 100 ppm showed least disease severity (23.33%) at 50 percent flowering with higher yield (2421 Kg ha-1) which was on par with seed treatment followed by foliar spray of salicylic acid at 50 ppm with disease severity of (23.33%) at 50 per cent flowering and seed yield of 2397 Kg ha-1.The defense enzymes superoxide dismutase (40.45 μg/50 per cent inhibition) and peroxidase (16.86 μg/ min/ mg protein) and secondary metabolites such as phenols (73.53 mg/g FW) and flavonoids (68.71mg/g FW) increased in seed treatment followed by foliar spray of salicylic acid at 100 ppm which resulted in least disease severity. | en_US |
