Seed-borne fungi of soybeans (Glycine max [L.] Merr) in the guinea savannah agroecology of Nigeria

Seed health testing of fifteen soybean cultivars obtained from five locations in the Guinea Savannah agro-ecology of Nigeria was carried out using two main seed health testing methods described by the International Seed Testing Association (ISTA); the standard blotter and two variants of agar plate incubation method (Potato Dextrose Agar and Czapeck Dox Agar plate methods) to determine the seed infection by fungi. Seed component plating was also carried out to determine the most active site of infection of the seeds by the fungi. Five fungal species were isolated from the cultivars tested. The percentage of seeds infected with Fusarium sp. and Penicillium sp. was significantly different (p
