Abstract

Four legume crops, viz., groundnut (Arachis hypogea L.), soybean (Glycine max (L.) Merr.) of Kharif season, chickpea (Cicer arietinum L.), and lentil (Lens esculentum L.) of Rabi season belonging to family Fabaceae were taken for investigation of seed-borne mycoflora. Since these are severely affected by many plant-pathogenic fungi at various stages of the whole life cycle, they were chosen for the study. Many post-harvest fungal pathogens cause severe loss by contaminating the grains with various mycotoxins and also deteriorate the nutritional quality of grains. The goal of any agricultural system is to increase the yield of crops as per the population demand. Various eco-friendly management practices were performed on highly mycotoxin-producing isolates of Aspergillus flavus and A. niger isolated from these grains. Four Trichoderma isolates (T2, T3, T4 and T5) were used as a biocontrol agent in the dual culture method to check antagonism between various Aspergillus isolates and Trichoderma isolates. It gave a satisfactory result in controlling mycelial growth. Achyranthes aspera leaf and stem phytoextract (10%, 20%, 30%, and 40%) was used as a botanical treatment in the well diffusion method, which successfully restricts the Aspergillus spp. mycelial growth.
