Abstract:

Seeds/grains may have the risk of association of a pathogen while exporting. They are, therefore, routinely tested under phytosanitary regulations to prevent pathogens movement along with maize grains/seeds into new territories and also affect seed quality. As there is an increased demand for the export of maize from India and maize seed borne fungal pathogens are concern of phytosanitary regulations which are detected through the different seed health testing methods. Hence, maize seeds of Four varieties (DHM-121, DHM-117, BML-06 and local from chenevelly) tested for seed borne fungal mycoflora by blotter and agar plate method of seed testing as recommended by International Seed Testing Association (ISTA).The external seed borne pathogens were detected as Aspergillus flavus, A. niger, Fusarium moniliformae, Alternaria alternata and Curvularia lunata in both blotter and agar tests. Whereas internal seed borne pathogens were detected as Bipolaris maydis, Colletotrichum graminicola in agar plate method. Hence it is recommended that for the detection of Bipolaris maydis, Colletotrichum graminicola agar test methods are required.
