Although it’s not the most environmentally friendly option available, it is a powerful and economical choice for those needing effective weed control.

The Whitetail Institute Slay Selective Broad-Leaf Weed Control Herbicide is designed specifically for managing weeds in deer food plots. One of its strengths is its selectivity, meaning it targets broadleaf weeds without harming clover and alfalfa, crucial for maintaining the health of these food plots. The active ingredients are effective, especially when used with a surfactant or oil additive, ensuring thorough weed control. This herbicide can cover up to four acres with a single pint, making it a cost-effective solution for large plots.

Its application is user-friendly, suitable for ATV or tractor sprayers, and is best applied in spring or early summer when weeds are in their initial growth stages. This timing is essential for optimal weed control and prolonging the life of the food plot. However, users need to be aware that they will need to purchase a surfactant or oil additive separately, adding to the initial setup cost.

A key consideration is its rainfastness and residual control, ensuring that the herbicide remains effective even with environmental challenges. While this product is designed with the specific need of deer food plot management in mind, it might not be suitable for more generic lawn or garden weed control due to its targeted nature. Its best use is for those dedicated to maintaining healthy and productive food plots for wildlife management and hunting purposes.
