Abstract
Seed borne pathogens play a vital role in causing diseases of pulse crops. Hence, with a view to study mycoflora and their role, seed samples of two pulse crops viz. cowpea (Vigna uaguiculata (L.) Wal.p.) and gram (Cicer arietinum, L.) were tested for determining the range of mycoflora associated with seeds. The isolations were made on moist blotting paper and potato dextrose agar with and without pretreatment with 0.1 percent mercuric chloride. From, seeds of both the crop, 22 fungi were detected, out of which Macrofomina phaseolina, Colletotrichum sp. Penicillium, oxalicum. Fusarium. spp., Chalara state of Ceratocystis paradoxa, Curvularia lunata, Aspergillus tamarii. A. flavus and Altenaria sp, were found as strong pathogens on cowpea and gram, both under laboratory and glass house conditions. Next in order were Aspergillus niger van. Tieghem, A. ochraceus, Corynespora cassicola, Penicillium variabile and Aspergillus flavus.
