Good info thanks. That's another thing dual is more suitable for fine soil then prowl but prowl does good in Sandy soil with lower rates. You have to pour the coal to fine soil with prowl but 1.33 pints of dual no matter the soil. If I planted corn and beans together they would have to be round up ready or the weeds would get me due to lack of herbicide options. I have stopped planting corn due to my neighbors cows I think they can smell it or something. I had the best corn crop ever a few years back ears as big as your forearm on about 40 acres and about 60 cows got into it in September and eat it to the ground. It's was about as mad as I've ever been especially when the jackass blamed me for planting corn on my place.
