| 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 compost tea revealed that maximum inhibition of A. helianthi was recorded in compost tea at 25 per cent (60.50%) followed by compost tea at 20 per cent (58.50%) and 15 per cent (53.80%). In field conditions, foliar spray of compost tea at the rate of 1:10 ratio at 30, 45 DAS and propiconazole at 1mlL-1 at 60 DAS increased the growth parameters like plant height (245.93 cm), stem girth (4.60 cm), number of leaves (9.35) and chlorophyll content (42.97). Foliar spray of compost tea with propiconazole was effective in controlling the Alternaria blight of sunflower with least disease severity (10.37%) and higher yield (2201.41 Kg ha1) which was on par with foliar spray of seaweed formulation (LBD-1) at 30, 45 DAS and propiconazole at 60 DAS with disease severity 12.32 per cent and seed yield of 1928.04 Kg ha-1. The defense enzymes such as superoxide dismutase (39.47 µg/50 per cent inhibition) and peroxidase (16.86 µg/ min/ mg protein) and also secondary metabolites such as phenolics (67.92 mg/g FW) and flavonoids (60.01 mg/g FW) increased in foliar spay of compost tea with propiconazole treated plants which resulted in least disease severity. | en_US |
