Abstract: Wilt disease (Fusarium oxysporum f. sp. udum) is one of the most destructive soil-borne diseases of Pigeon pea. Field experiments were conducted at supervision of Asha Bhagwan Bax Singh P.G. College Ayodhya, during Kharif seasons of 2017 and 2018 in the farmer's field of Ayodhya and Ambedkarnager district of Uttar Pradesh, to find out different integrated management levels of control schedule for pigeon pea wilt disease. All treatments had a significant effect on disease incidence, seed yield and disease index in both the consecutive years of experimentation. Nine Seed treatment combinations viz. T1- Trichoderma viride alone @ 12g/kg seed, T2- Thiram + Carbendazim + Trichoderma viride + Rhizobium @ 13 g /kg, T3- Thiram + Carbendazim+ Trichoderma viride + Rhizobium + Soil application of Trichoderma viride @ 10 g/kg, T4- Carbendazim 50 % WP (ST) @ 5.0 g/kg, T5- Carbendazim 25 % WP + mancozeb50 % WP (ST) @ 3.0 g/kg, T6- Neem seed cake (SA) @ 5.0q/ha.. T7- Castor seed cake (SA) @ 6.0q/ha, T8- neem seed cake (SA) + [carbendazim 25 % WP + mancozeb 50 % WP] (ST) + azoxystrobin 23 EC (SD) + Soil application of Trichoderma viride @ 20 kg / ha + 1 kg/ ha +3 g / kg seed + 12 g / kg seed +12 g and T9- untreated control were evaluated against wilt disease of pigeon pea on the popular variety Bahar. T8- neem seed cake (SA)+ carbendazim 25 % WP + mancozeb 50 % WP (ST) + azoxystrobin 23 EC (SD) + Soil application of Trichoderma viride @ 20 kg / ha + 1 kg/ ha +3 g / kg seed + 12 g / kg seed +12 g was found most effective with minimum wilt incidence 2017 and 2018 (3.40 % and 5.50 %), reduction over control (%) 93.99 & 90.86 and disease index 61.76 & 61.48 % and recorded maximum yield 2017 and 2018 (2160 and 2100 kg/ha), respectively followed by T3- Thiram + Carbendazim+ Trichoderma viride + Rhizobium + Soil application of Trichoderma viride @ 10 g/kg, 10.90 and 11.60 % wilt incidence, reduction over control (%) 80.74 & 80.73 and disease index 55.17 & 55.26 % with yield kg/ha was 1740 kg /ha and 1860 kg/ha.
