I am growing mangels next year and the weeds I had this year were lambsquarters, ragweed, canadian thistle, foxtail, shepherds purse, and purslane. If I spray a post emergent application of 1/2 OZ UPBEET, 8 oz clethodim, 3 oz stinger, and 5 oz of a surfactant on one acre will that control the weeds pretty well? Are those good/correct rates?
