Pathogenic fungi in seeds of tropical forage species.
Seedborne fungi of introduced forage species were investigated in Argentina on 400 seeds representative of each species. The most common fungi in grasses were Phoma sp., Fusarium, Alternaria and Epicoccum on Panicum; Cladosporium, Phoma and Fusarium on Setaria anceps [S. sphacelata var. sericea]; Drechslera sorokiniana [Cochliobolus sativus], Drechslera sp. and P. sorghina on Chloris gayana; Phyllosticta sp., Curvularia sp. and Drechslera sp. on Dichanthium aristatum and Paspalum urvillei. The most important fungi in legume seeds were Cladosporium cladosporioides in Leucaena leucocephala; Aspergillus, Penicillium and Fusarium in Dolichos lablab [Lablab purpureus]; and Aspergillus flavus, Curvularia sp. and Penicillium sp. in Glycine wightii [Neonotonia wightii].
