| So drilled soybeans into probably 5 to 7' c. rye one time in a wet year where I had trouble seeing when wet spots were coming ahead, but got thru it. I don't use high maintenance markers, instead a light bar which is accurate enough imo, The rye was sprayed before drilling (mistake by me) and the field avg. 58 bu./acre with my best comparison nearby field w/o a cover crop drilled just a day apart yielded mid 70's, so I think it did hurt yield that particular year, but the field was too wet when drilled so that might have been the bigger factor in the reduced yield, and spraying a week or so before drilling helped the field stay too wet. Learning curve mistake. Now if faced with a similar scenario, I drill first into head high live c. rye.
Usually I get the c. rye sprayed a couple weeks after drilling beans green, with beans often emerged, which often correlates to about knee high c. rye. That's my comfort range, not to say it's the right stage, just the one I shoot for. As long as it's not abnormally dry, going up to a month after drilling before spraying works. Pretty wide window to get the spraying done. Try to get the drilling beans done in April, starting around April 10th or so. | |

What’s the latest you’ve successfully terminated cereal rye after planting soybeans?
