Alternaria protenta was detected from seeds of sunflower (Helianthus annuus) cv. Taiyo. This fungus sporulated abundantly on glucose-peptone agar (GPA) or Leonian agar (LA). The pathogenicity of A. protenta harvested from GPA or LA was significantly (P < 0.05) greater on seeds of sunflower cvv. Big Smile, Sun Bright and Pachino than the pathogenicity of conidia from dextrose-nitrate agar. The amount of inoculum affected the germination rate of cv. Taiyo but not for cvv. Big Smile and Sun Bright…

Trichoderma harzianum antagonistic activity and competition for seed colonization against seedborne pathogenic fungi of sunflower

TRIC8 inhibited mycelial growth of the fungal pathogens between 70·67 and 76·87% with the strongest inhibition seen with deferred inoculation, and Alterations in hyphae were observed in all pathogens.

Seed-borne fungi of ornamental flower plants

New records of seed-borne pathogens were recorded in seeds of the all species of flowering species tested except for ageratum, baby’s breath, salvia, statice, and stokesia.
