Brodale I farm in Southwestern Ontario.  Thanks for the input it seemed to help althought we changed varieties today and it thrashed much easier and was yeilding 20 bu_ac less.  Yeild s in our area this year are exceptional.  Probably 20 - 30 Bu above average however fusaium levels are running .5-8% and most is grading feed so ther goes another $15-20 _mt. Thanks again for the help.
