Grazing and Haying Restrictions for Herbicides (07/01/21)
Last week’s Crop and Pest featured a thorough article on considerations for haying or grazing small grain crops. One supplemental addition to that article is the consideration for time interval between herbicide application and grazing or haying the crop. I realize that many of the small grain fields getting turned into feed may not have received a herbicide, but for those that did, we need to follow the proper time interval from application to “harvest”.
Lists of the grazing and haying intervals for many of our herbicides can be found on the Restrictions on Grazing/Feeding/Haying of Crops Treated with Herbicides webpage or on pages 109-112 in the 2021 North Dakota Weed Control Guide.
