Agronomic considerations for reducing dexynivalenol in wheat grain.

Wheat fields under an array of agronomic practices were studied during harvest across southern and easthen Ontario Mature wheat grain samples were hervesred by hand and analyssed for DON. The amount of variation in DON levels associated with year and agronomic effects was calculated from simple linear models. The largest factor associated with variation in DON levels was the year. Year effects accounted for 48% of the variation in DON levels across  all fields during four years of the survey, followerd by cultivar (27%), and the crop one year  previous  to wheat (14-28%  depending on the  year).  No  effect  on  DON  could  be   detected  from  other  agronomic  factors  including  tillage   system,  crops  planted  three  years before wheat,  or  type of  nitrogen  fertiliser  applied  in  the  spring.
