Two strains of bacteria, Bacillus subtilis T 99 and Streptomyces sp. G 43 , antagonistic to phytopathogenic soil fungi, were isolated from natural substrates. In vitro tests indicated activities against different Fusarium species including formae speciales of Fusarium oxysporum, Stromatinia gladioli, Botrytis cinerea, Thanatephorus cucumeris , and other fungi. For both of the antagonists, biotechnical procedures were developed yielding culture broth for large‐scale application. After dilution of these media antagonists were tested successfully in vivo by soil drenching treatments in a greenhouse carnation production facility. The application forms of the fermentation media developed were capable of suppressing wilt disease of Dianthus .
