This diploma thesis concentrates on testing the efficiency of antifungal and biological agents against fungal pathogens Colletotrichum acutatum and Fusarium culmorum. Five single-component antifungal agents were used for the testing and the sizes of the inhibition zones were evaluated. It was found out that the sensitivity of the pathogens to the agents varies. Most effective against Colletotrichum acutatum was the azoxystrobin compound in the Ortiva agent, whereas against Fusarium culmorum it was the Horizon agent with the active compound tebuconazole. With the biological agents, the zone of mycoparasitism was evaluated and the effect of the agents on the growth of the phytopathogenic fungi mycelia was analysed. Trichoderma harzianum exhibited better ability to colonize and suppress the growth of the pathogens‘ mycelia than Pythium oligandrum.

Three cultivators, Rabewerk, Kongskilde and Hiniker, and three intercrops, soybean, lupin and red clover + rye grass were investigated for their impact on the incidence of ear rot of corn, a common disease of maize in eastern Canada. Wheat was seeded in the corn rows to serve as an additional indicator of cultivation and intercropping effects on the pathogen. An artificial inoculum of F. graminearum that produced perithecia and ascospores was used to mimic natural inoculum. / In 1993 and 1994, the infection in the corn was not very severe and there were no differences between the treatments and the controls. / In 1993 and 1994, at both sites, wheat seeds from cultivation trials showed a tendency for greater disease incidence in the non-cultivated herbicide treatment when compared to any of the other cultivator treatments. Cultivators till the soil and bury corn residues, this action led to the destruction of some of the inoculum and a subsequent reduction of the disease incidence in the cultivated plots. / In the intercrop trial of 1993 and 1994, wheat infection was moderate to severe, except at L'Assomption in 1993, but no significant differences were observed among the treatments. It is believed that interplot interference, due to ascospores moving from one plot to the next, masked differences. / The results indicated that weed cultivation would have a negligible or no effect on the development of fusarium ear rot of corn in Quebec.
