Managing cereal rye

Managing cereal rye

Farm and Ranch October 22, 2010 What is the best way to address the problem of cereal rye in wheat fields? Joe Yenish, former Washington State University extension weed scientist, says the best thing is to rotate into a spring crop for several years, something he recognizes is not always an option.

Yenish: “It is one of the more strongly winter annual type of grasses in that it needs that cold period. So, if you can go to a spring crop you have some relatively inexpensive options in killing it with glyph sate or possibly tillage if that is your system. From an in-crop stand point the best situation right now would be to use the Beyond Clearfield but if you are doing that you might as well plan on higher rates. Plan on split applications, early versus late to really get a handle on it and get the best level of control and that certainly is going to add to your chemical bill straight up and in the situation with split applications you are paying for those two passes across the field that you might not otherwise be paying for.”

Yenish says for a winter broadleaf crop like canola, there are higher rates labeled for some of the broadleaf grass herbicides like Assure II.

Yenish: “And then the possibility of Roundup Ready Canola is also a strong method of controlling the rye in the winter annual broadleaf crop.” :

Yenish says the longevity of cereal rye seed in the soil is at least up to ten years and it could be longer than that.
