Abstract:

Seed dressing fungicides viz., thiram, and carboxin and combination product of thiram + carboxin were evaluated in cotton during kharif seasons of 2012 to 2014. Cotton variety Narasimha was raised in plots of 31.5 sq. m adopting a spacing of 105 x 60 cm. Ten treatments viz., T1 - Seed treatment (ST) with thiram @ 2g/kg seed; T2 - ST with thiram @ 3g/kg seed; T4 - ST with thiram @ 4g/kg seed; T4 - ST with carboxin @ 1g/kg seed; T5 - ST with carboxin @ 2g/kg seed; T6 - ST with carboxin @ 3g/kg seed; T7 - ST with thiram + carboxin @ 2.5g/kg seed; T8-ST with thiram + carboxin @ 3.5g/kg seed; T9-ST with thiram + carboxin @ 3.5g/kg seed and T10 - Untreated control were imposed at the time of sowing in randomized block design with three replications. Data on seed borne diseases was collected by adopting 0-4scale and disease intensity was calculated. Treatment wise yield data was recorded and Incremental Benefit Cost Ratio (IBCR) was calculated. Combination of carboxin 37.5% WP + thiram 37.5% DS 4.5g/kg resulted in lowest mortality (4.11%) and lowest intensity of Alternaria leaf spot (4.11%) with maximum yield of 9.65q/ha. IBCR of different treatments varied between 4.82 and 4.93. Hence thiram @ 3g/kg or carboxin @ 2g/kg or combination product @ 3.5g/kg is recommended for seed treatment in cotton.
