I would recheck that. Also, it depends on what kind of hay field you have. If it's bermuda, Poast is a no no. I use a 3 % solution of Poast to kill bermda grass in my centipede yard. Two weeks later the centipde is thriving while the bermuda is toast.
Also, my Poast is brown in the jug and white after mixing. It has a strong odor, so I usually mix some in with glyphosphate(even though not needed) while spraying RR beans. The deer will quit eating beans after spraying. It was widely used for soybeans as a grass killer before RR varieties came out.
