IDM practices for the management of foliar diseases of sesame (Sesamum indicum L.)

Abstract

Sesame (Sesamum indicum L.) is the most ancient and important oilseed crop, with rich source of protein, high quality seed oil and many antioxidant properties is extensively grown in India. Occurrence of foliar diseases are Alternaria leaf spot and powdery mildew become a major constraint in recent years for successful and profitable cultivation of sesame. Field experiment was conducted on integrated disease management practices to combat foliar diseases and to increase the seed yield of sesame during two consecutive years (2015 and 2016) at Regional Research Station, Vridhachalam, Tamil Nadu Agricultural University, Tamil Nadu. Integrated management of Alternaria leaf spot and powdery mildew of sesame were conducted with eight treatments. Among the different treatments tested in field condition, the minimum incidence of Alternaria leaf spot (15.14 % and 13.72%) with higher yield of 642 kg/ha and 657 kg/ha were recorded in seed treatment with T. viride @ 10 g/kg + furrow application of T. viride (2.5 kg/ha enriched in 100 kg of FYM) @ 250 kg/ha + foliar spray of myclobutanil @ 1 g/l during Kharif 2015 and 2016.The reduction of Alternaria leaf spot was also directly associated with an increase in seed yield. In case of powdery mildew, the minimum incidence 5.83 and 9.65 PDI with higher yield of 642 kg/ha and 657 kg/ha were recorded in Kharif - 2015 and 2016 with spray of myclobutanil 10% WP @ 1 g/l.
