Representatives of each category of inhibition.
P. destructans was inoculated on all plates as in the negative control (N.C.), and all photographs were taken 14 days after P. destructans inoculation. Classifications are (left and centre panels): (0) negligible (< 50%) inhibition, (1) considerable (50% to 85%) inhibition, (2) nearly complete/complete (> 85%) inhibition. Additionally, if applicable (right panel): (A) growth of the isolate is limited by P. destructans, (B) the isolate grew over P. destructans such that affected P. destructans colonies were no longer visible, (C) P. destructans colonies were present, but uniformly smaller than in the control plate.

Evidence of inhibition of P. destructans by volatiles produced by antagonists.
P. destructans and an antagonist were inoculated on separate pieces of agar within a single Petri plate. Photographs show P. destructans inoculated on the top and an antagonist on the bottom of the plate except for control plate (left), which contains P. destructans with no antagonist. Volatile production by antagonists was evident as considerable or complete growth inhibition of P. destructans. All photographs were taken 14 days after inoculation.
