Please Die Rye

Over these past summer-like days, undoubtedly you’ve seen some rye growth! So now is definitely the time to be thinking about termination.

Killing the rye through plow down or herbicides are your options right now. Incorporating a winter rye cover crop in its vegetative stage will result in the quickest nitrogen release to your corn crop. An early kill can give a 30 to 50 pound nitrogen credit.

When rye reaches the boot stage (right before the head emerges), it may be harder to kill and will be slower to break down. It also may tie up nitrogen and delay its availability to the corn crop.

If you are planning a no-till corn planting, terminate with herbicide immediate after planting –timing is key so be sure planting aligns with a nice stretch of weather. If you are planning to terminate the rye with a roller-crimper, you must wait until the rye is flowering — when the anthers are clearly visible and shedding pollen. If you do not wait until this critical stage, the winter rye will likely “stand back up” shortly following rolling and crimping.

Enjoy the nice weather.
