An experiment was carried out at Agricultural Research Station, Ladol to test the efficacy of some effective systemic fungicides viz. tebuconazole 50%+trifloxystrobin 25% WG, difenconazole 25% EC, hexaconazole 5% EC and tebuconazole 25.9% EC with their prefix concentrations against leaf spots or tikka disease of groundnut. A variant with no application of fungicide was used as a control. All the treatments reduced the disease intensity significantly as compared to untreated check. The per cent disease intensity was recorded periodically at 60, 75 and 90 days after the sowing with consecutive three spray of fungicides (before and 7 days after spray) at 15 days interval and was found moderate to medium in range (13.72–44.84 per cent). The minimum disease intensity was recorded in the treatment T3 at 90 DAS at applied after third spray (7 days after spray) with its PDI 24.35 per cent. After harvesting of the crop, the highest pod and haulm yield was also obtained from the plots treated with the same treatment T3 i.e. spraying of tebuconazole 50%+trifloxystrobin 25% WG @ 0.25% concentration (pod-2422 kg; haulm-3207 kg ha-1) followed by the treatments T2 (pod-2407 kg; haulm-3178 kg ha-1) and T7 (pod-2378 kg; haulm-3167 kg ha-1). Here, The efficacy of combination fungicide of triazole and strobilurin group, i.e. tebuconazole 50%+trifloxystrobin 25% WG @ 0.25% concentration was found very effective against early and late leaf spots of groundnut and increasing the pod as well as haulm yield also.
