Abstract:
Colletotrichum truncatum pathogen of soybean is seed born, and attack at later growth stage is a threat to quality seed production. Field trial was conducted to evaluate the efficacy of fungicide and bio-agent as seed dresser, foliar application and combination of seed dressing and foliar application. In pooled data of three years the highest seed germination was recorded in treatment T₁ (94.39%). The least percent disease index (8.74%), pod infection (12.83%), maximum grain harvest (1628 kg/ha) and the highest ICBR ratio (1:4.2) was recorded in T₄-carboxin + thiram @2 g/kg seed + foliar application of thiophanate methyl @0.1% respectively at 50 and 70 days after sowing. The pooled data record recommended that the seed dressing with carboxin + thiram @ 2 g/kg seed + foliar application of thiophanate methyl @0.1% respectively at 50 and 70 DAS improve in seed germination and plant stand, least foliar percent disease index and pod infection, improved in 100 seed weight, seed yield and higher ICBR ratio.
