Acremonium alternatum, like several other hyperparasites (Hijwegen, 1986; Jarvis, 1989), is effective against cucumber powdery mildew caused by Sphaerotheca fuliginea (Malathrakis, 1989). To ameliorate the effectiveness of hyperparasites several additives have been tested (Philipp, 1984). In the present paper data of a study on the effectiveness of A. alternatum with or without glycerol are presented.
