Beschreibung:
AbstractFour known antagonistic microorganisms, namely, Bacillus cereus, Bacillus subtilis, Aspergillus ochraceus and Penicillium cyclopium were paired against four pathogens of maize, namely, Curvularia pallescens, Drechslera maydis, Fusarium moniliforme and Macrophomina phaseoli and a pathogen of cassava, Colletotrichum gloeosporioides f. sp. manihotis on potato dextrose agar. The main aim was to test the ability of the antagonists to inhibit the growth of the pathogens. Whereas B. cereus and B. subtilis inhibited the growth of C. pallescens, D. maydis, M. phaseoli and C. gloeosporioides f. sp. manihotis, they did not inhibit the growth of F. moniliforme. A. ochraceus and P. cyclopium were effective only against M. phaseoli. Inhibitory activity on the target organisms are thought to be due to some toxic substances produced by the antagonists.
