Preliminary investigations on the effect of commercial glyphosate formulations on pathogenic Fusarium spp.
|dc.description.abstract||Diseases of cereal crops caused by pathogenic fungi can lead to estimated economic losses of over $100 million to producers annually in western Canada. One fungal disease that is becoming more prevalent in Saskatchewan is Fusarium head blight (FHB), caused primarily by Fusarium graminearum and to a lesser extent F. avenaceum. These pathogens can reduce grain yield and quality. There is a very low tolerance for Fusarium damaged kernels in grain samples due to the presence of mycotoxins that are very detrimental to human and animal health. This disease also causes reductions in seed germination and seedling vigour. Cultural practices including crop rotation and fungicide use have done little to reduce the impact of FHB. However, recent studies have shown significant reductions of FHB severity in fields under zero-till production systems compared to minimum-till systems. One factor which may contribute to the lower FHB in zero-till than min-till may be the greater use of glyphosate-based herbicides in the zero-till systems. A study was conducted to evaluate the effect of different commercial glyphosate-herbicide formulations on the in vitro growth of cereal pathogenic Fusarium spp.||en_US|
