Efficacy of fungicides seed treatment in improving seed quality and health in Paddy (Oryza sativa L.)

The research work was carried out on paddy variety PB1509 in Department of Seed Science and Technology, CCS HAU Hisar during 2021 to assess the efficacy various fungicides improving seed quality health. results revealed that maximum germination (91.11%) recorded seeds treated with Pyraclostrobin 10% CS followed by Picoxystrobin 6.78% +Tricylcazole 20.33% SC (90.67%) single dose. With double dose, significantly high 6.78%+Tricylcazole (88.33%) Azoxystrobin18.2% + Difenoconazole 11.4% (88.17%) comparison control (84.67%). In poor vigour index-I (1749) observed 12%+Propiconazole 7% Propiconazole 13.9%+ Difenconazole 13.9% EC (1789) (2254). detrimental effect majority fungicidal treatments Maximum infection (25.00%) untreated while no dose amistar top, nativo, galileo sensa systiva. reduced after two weeks both Double from 9.05 5.95%. fungus found rotten ungerminated could not be identified. frequency unidentified (0.23) (untreated seeds) cabrio top (0.11) minimum (0.03) systiva seeds.
