Abstract: Three bioagents were evaluated for management of anthracnose disease of yam by sett treatment, soil application and spray methods with untreated control. Among the seven treatments, higher germination (86.46%) and lowest disease intensity (19.61%) was observed in Sett biopriming with Trichoderma harzianum @ 10 g/kg + 2 sprays of T. harzianum (0.5%) as compare to rest of the treatments. While, lowest germination (76.04%) and highest disease intensity (45.57%) was recorded under Control. Effect of treatments on the yam tuber yield was also found significantly superior as compared to the control. The results showed that the maximum yield was obtained in Sett biopriming with T. harzianum @ 10 g/kg + 2 sprays of T. harzianum (0.5%) (7651.75 kg ha^-1) which was at par with Sett biopriming with T. viride @ 10 g/kg + 2 spray of T. viride (0.5%) (7343.11 kg ha^-1). While, lowest yam tubers yield (5594.14 kg ha^-1) was recorded in control.
