1 Spot treatment rate per label. Do Not Apply more than 19.2 oz/ac, Do Not treat mor then 10,000 ft/ac for spot treatments 2 Significant undesirable injury may occur 3 Do Not apply Basagran T&O to any newly seeded or newly sprigged turfgrass until seedlings or sprigs are well established or injury may result 4 Check label for further instructions 5 Do not Exceed 1 qt/ac
10 Post-emergent applications targeted spot applications and not broadcast treatments 11 Do not apply to bermudagrass sod farms 12 Bleaching/discoloration can be expected to the desired turfgrass 13 F or application onto golf course greens, do not apply more than 2.5 pt./A (1 lb. active ingredient) per application and ensure there is no overlap of the spray or turfgrass injury may occur. Split applications of the rate can be made but the total amount on greens should not exceed 1.5 lbs. active ingredient 14 D o not treat bermudagrass with GameOn when the mowing height is less than 1/2 inch. Hybrid bermudagrass can be more sensitive to injury than common bermudagrass. Do not apply more than 3 pints of GameOn per acre to these grasses unless temporary turfgrass injury can be tolerated.
E=excellent (>90%) control. G=good (80 to 90%) control. F=fair (70 to 80%) control. Good control often is achieved with a repeat application 1 to 3 weeks after the initial one. P=poor (<70%) control in most cases and/or not labeled for use. —=control unknown as not all weeds have not been tested for susceptibility to each herbicide listed. Note: repeat applications usually 1 to 3 weeks apart are needed for most herbicides on most weeds especially as they mature (produce flowers and/or seed heads).
