Ryegrass questions have become much more prevalent this week. I have had no good answers for the calls on how to control ryegrass that escaped the glyphosate burndown in emerged corn. Herbicides like Accent or Steadfast will not control ryegrass. Liberty tankmixed with atrazine on LL corn would burn the ryegrass back some and is the only even fair option that is available.

I have written a couple of pieces on fomesafen carryover into grain sorghum. I emphasized fomesafen because it is used on almost all soybean acres in Tennessee. However, I would be remiss if I did not add that some other herbicides commonly used in soybean have lengthy plant backs to grain sorghum as well. Continue reading
There have been a number of calls this spring on weed control in conventional soybean. This is not new as calls on weed control in conventional soybeans have been more frequent the last two years. Typically the weed spectrum that is the main issue with these calls is not Palmer amaranth but cocklebur and sicklepod. Continue reading
The comments below were posted sometime ago, but with corn planting time upon us, I’ve updated some take home points. Continue reading
A wet and mostly cold March has us well behind the pace for burndown. As soon as the weather permits corn planting will take priority followed by burndown for grain sorghum and early planted soybean. Continue reading
When planning your burndown does a residual make sense? That depends on if a follow-up burndown is planned at planting, the expected planting date and what is the intended crop. If the expected planting date is 3 weeks or so off and the plan is to burndown with something at planting then a residual in with the burndown now is probably not warranted. However, if the intended planting date is more than 30 days away, then a residual can provide the advantage of not having a big, grown up mess to have to plant into. Continue reading
It finally looks like this long winter is coming to a close! I hope we can start putting out burndown applications in the next week to ten days. Continue reading
