When managing corn crops for high yields, remember it’s always best to start with a clean field. Start with an Autumn™ Super (2) application in the fall, and the following spring use Corvus® (2, 27), a pre-emergence residual herbicide which has overlapping modes of action to control early season problem weeds. Corvus pre-emergence herbicide from Crop Science is the only corn herbicide to offer burndown, residual and reactivation. Residual activity prevents new weeds, while reactivation controls late weeds.
The multiple modes of action in Corvus deliver consistent, broad-spectrum control of grasses and broadleaf weeds, including weeds resistant to glyphosate-, ALS-, PPO- and triazine-based herbicides.
A wide application window allows for application from pre-plant to early postemergence at V2, making it an effective, long-lasting first pass herbicide in a two-pass system. Depending on the weed spectrum in your field, such as fields without heavy Palmer amaranth and waterhemp pressure, Corvus may still be a great one-pass option.
A recommended two-pass program starts with a pre-emergence application of Corvus herbicide. The second pass should include a postemergence product such as Laudis® herbicide (27). If using Laudis following an application of Corvus, add another effective herbicide with a different mode of action, such as DiFlexx™ (4) herbicide, Liberty® (10) or atrazine, to ensure you are using multiple modes of action in your weed control.
Another pre-emergent herbicide Crop Science offers corn growers is Balance® Flexx (27). Follow a pre-emergent application of Balance Flexx with a postemergence herbicide to control multiple weed flushes. Balance Flexx has the unique power to reactivate with as little as a half-inch of rain to control late-emerging weeds. It controls glyphosate-, triazine-, PPO- and ALS-resistant weeds, including resistant marestail, common ragweed, waterhemp and Palmer amaranth. Balance Flexx even controls tough grasses, such as woolly cupgrass.
Balance Flexx fits into many cropping systems. Its superb weed control power combined with state-of-the-art crop safety innovation enables growers to readily rotate from corn to other key crops with little or no delay.
Capreno® herbicide (2, 27) is a postemergence herbicide option for corn from Bayer. It has the longest-lasting residual of any post product on the market. With multiple modes of action, Capreno controls more than 65 grasses and broadleaves, including those resistant to glyphosate, PPO, ALS, dicamba and triazines.
Liberty® is the preeminent weed management system with a unique chemistry and novel mode of action to offer superior control of a broad spectrum of resistant and tough-to-control weeds in LibertyLink® corn. It is THE non-selective post-emergence herbicide that still effectively handles grasses and broadleaf weeds including glyphosate resistant Palmer amaranth, giant ragweed, marestail, waterhemp and kochia.
