The following article is being added to the current issue of CropWatch.unl.edu

Based on a recent Nebraska survey about cover crops, producing forage was among the top five desired benefits. With tighter margins this year, more producers may be considering grazing or haying cover crops to offset the expense while still capturing the longer term benefits. An important consideration of using these forage cover crops following corn or soybean is that herbicide label rotation restrictions from the agronomic crop MUST be followed to avoid potential carryover to animals consuming this forage. The recommendations in this article are for forage cover crops because the requirements to integrate them in a herbicide program are most restrictive.

Tables provide Plant-Back Restrictions for Cool- and Warm-Season Forage Cover Crops after Pre-Emergence and Post-Emergence Herbicide Applications in Corn and Soybeans.
