| nivalenol-type populations of fusarium graminearum and f. asiaticum are prevalent on wheat in southern louisiana. | u.s. populations of the fusarium graminearum clade cause head blight on wheat and barley and usually contaminate grain with the trichothecene mycotoxin deoxynivalenol (don). recently, however, individual nivalenol (niv)-type isolates from the united states were described that belonged to either the newly described species f. gerlachii or the genetically distinct gulf coast population of f. graminearum sensu stricto (s.s.). here, we describe the discovery of niv-type f. graminearum s.s. populatio ... | 2011 | 20822434 |
| post-anthesis moisture increased fusarium head blight and deoxynivalenol levels in north carolina winter wheat. | abstract current models for forecasting fusarium head blight (fhb) and deoxynivalenol (don) levels in wheat are based on weather near anthesis, and breeding for resistance to fhb pathogens often relies on irrigation before and shortly after anthesis to encourage disease development. the effects of post-anthesis environmental conditions on fhb are poorly understood. we performed a field experiment at kinston, nc, to explore the effects of increasing duration of post-anthesis moisture on disease i ... | 2009 | 19271972 |
