These diseases are caused by several species. The most frequently blamed belong to Rhizoctonia, Fusariumand Pythium kinds. These two last genus appear to be sensitive to an organo-phosphorated weedkiller: the glyphosate [1, 2, 3]. The tests carried out towards Fusarium oxysporum, Fusarium oxysporum f. sp albedinis(Killian & Maire) <br />Gordon, and some stocks of Pythium, show that glyphosate concentrations tested (0.5 - 1 - 1.5 and 2 mM) decrease Fusaria mycelian growth until inhibiting it at 2mM concentration level; whereas <br />growth of Pythiumis inhibited from 0.5mM concentration. <br />Microscopic studies of the mycelial colonies reveal that 0.5 - 1 and 1.5 mM glyphosate concentrations increase Fusarium oxysporumconidia number; 1.5 mM molarity stimulates chlamydospore formation. Concerning with Fusarium oxysporum f. sp albedinis however, a <br />reduction in the number of conidia is observed at 0.5 mM; their absence at 1 and 1.5 mM is noted under the experimental conditions (T = 28°C, medium PDA). 2 mM concentration inhibits growing speed and reproductive organs production of Fusarium and Pythiumspecies.}, number={26}, journal={Sciences & Technologie.
