N2 - Application of cells of two isolates of fluorescent pseudomonads from soil to wheat seedlings prior to inoculation with Mycosphaerella graminicola (anamorph, Septoria tritici) or Puccinia recondita f.sp. tritici markedly reduced symptom expression. These Pseudomonas isolates, LEC 1 and LEC 2. also reduced in vitro growth of Geotrichum candidum. Rhizoctonia solani. Sclerotium rolfsii and S. tritici. Growth of the melanin‐producing isolate ISR398 of S. tritici was inhibited on silica gel thin‐layer chromatograms by compound(s) extracted with diethyl ether from King's Medium B colonized by Pseudomonas isolate LEC 1. The growth of the antagonistic pseudomonads on defined medium was not affected by the following commercial fungicides: benomyl, captafol, chlorothalonil, fenarimol, mancozeb, maneb, metalaxyl, prochloraz, propiconazole, triadimefon, and the herbicides 2,4‐D and diclofop‐methyl at the recommended concentrations
