Calonectria hemileiae reduced coffee leaf rust severity (CLRS) on coffee plants inoculated with Hemileia vastatrix.

CLRS of coffee plants inoculated with H. vastatrix at 20, 28, 36, 42, and 50 days after inoculation. Treatments were, respectively: inoculation with H. vastatrix and spraying of plants with antagonist (C. hemileiae) 72 h before (Ch/72Hv) or simultaneously (Ch/Hv) with the inoculation with H. vastatrix (Hv) and treated with fungicide (A). Abaxial surface of leaves represnting: control (B), Hv (C), Ch only (D), Ch/72Hv (E), Ch/Hv (F), and fungicide treatment (trifloxystrobin + tebuconazol) (G). Pictures taken 50 days after inoculation with H. vastatrix took place. Treatment means followed by the same letter, for each sampling time, are not significantly different (p ≤ 0.05) as determined by Tukey's test. Bars represent the standard deviation. n = 5.
