Inhibition of growth of fungi isolated from plants by Acremonium strictum

The fungus Acremonium strictum was isolated from rye grass, kikuyu and another species of Pennisetum. Two isolates of A. strictum significantly inhibited, in vitro, the rate of growth of five fungi commonly associated with grasses. Extracts from cultures of the isolates also inhibited the rate of hyphal elongation. From the evidence, these isolates of Acremonium are classified as endophytes and their relationship with the 'Balansioid' endophytes must be reconsidered.
