Integrated management of major diseases of sesame (Sesamum indicum L.)

Abstract

Among fungal diseases, stem and root rot, Alternaria leaf spot and Cercospora leaf spot were become major constraints for cultivation of sesame in South 24-Parganas district of West Bengal, India. Considering the fact, the following investigation was carried out for this pathological problem. Field trials conducted on integrated disease management practices to combat major diseases and to increase the seed yield of sesame during summer, 2018 and 2019. Minimum incidence of stem and root rot (8.8% and 11.2%) with higher yield of 527 kg/ha and 577 kg/ha were recorded in summer, 2018 and 2019 with application of organic amendment with FYM and neem cake @ 150 kg/ha (1:1, T4). In case of foliar diseases of sesame, applications of FYM + NPK @ 60:30:30 (1:1, T3) was found to be significantly effective by recording minimum incidence of Alternaria leaf spot (6.3% and 8.4%) and Cercospora leaf spot (4.2% and 5.3%) coupled with maximum yield (512 kg/ha and 541 kg/ha) with higher cost benefit (C:B) ratio in summer, 2018 and 2019.
