The efficacy of the compositions in controlling plant growth was tested by applying the compositions to the following plant species: Green Foxtail (“GRF”), Giant Foxtail (“GF”), Shattercane (“SC”), Barnyard Grass (“BG”), Redroot Pigweed (“PWV”), Common Waterhemp (“WH”), Common Purslane (“CP”), Kochia (“KO”), Velvetleaf (“VL”), Common Lambsquarter (“LQ”), Ivy Morning Glory (“MG”), at a rate of 0.5 pint per acre and at a rate of 1.0 pint per acre. Results for the 0.5 pint per acre application rate at 28 days post application are given in TABLE I below as percent control of plant growth for various plant species. Results for the 1.0 pint per acre application rate are given below in TABLE II as percent control of plant growth for various plant species.
