NovaGraz, a product from Corteva, combines florpyrauxifen (also known as Rinskor active) with 2,4-D, and has recently been approved for use in grass pastures, hayfields, and Conservation Reserve Program (CRP) acres.
It is effective for controlling a wide range of broadleaf weeds, including ironweed, cocklebur, wild carrot, buttercup, biennial thistles, ragweeds, plantain, poison hemlock, dandelion, marestail, and more. However, it is less effective on certain perennial weeds like horsenettle, milkweed, hemp dogbane, Canada thistle, and smooth bedstraw.
One of the main advantages of NovaGraz is its safety on many types of forage grasses, making it a suitable option for pasture management. It also preserves white clover, an important legume in many pastures.
However, it is harmful to other legumes, such as red and crimson clover, alfalfa, and birdsfoot trefoil, so care must be taken when applying it in mixed plantings.
The recommended application rate is 24 fluid ounces per acre, with the addition of methylated seed oil (MSO) for optimal performance. After application, there are minimal grazing restrictions, just a three-day wait period for any class of livestock, including lactating animals.
However, hay cannot be harvested until 14 days post-application, and manure must be kept away from sensitive areas for 30 days unless applied to pastures, corn, or wheat.
