Soybean and cotton are main hosts, but even on these hosts it is a weak pathogen. Has been isolated from other hosts, though primarily as a saprophyte or weakly pathogenic
VERTNI
Not considered a highly virulent fungal pathogen. Often found as a saprophyte or weakly pathogenic at most. This fungus should not be regulated on seed.
