Maximum Yearly Limits
Limitations on spot treatments to residential turfgrass: Spot treatment is defined as a treatment area no greater than 1,000 sq. ft. per acre. The maximum application rate is 1.8 fl. oz. per 1,000 sq .ft. per application (0.3 lb MCPP-p acid equivalent per acre). The maximum number of spot treatments is limited to 2 per year with a minimum of 30 days between applications.
Time Between Applications
A minimum of 30 days between applications of Speedzone.
Delay mowing 1 to 2 days before and after the application of Speedzone.
Effective Temperature Range
Do not broadcast apply when air temperatures exceed 90°F; some injury may be expected with spot treatments when air temperatures exceed 90°F. For warm-season turf, use the lower-end of the listed safe rates in warmer temperatures (above 80°F).
Rainfall or irrigation occurring within 3 to 4 hours after application of this Speedzone may reduce the effectiveness.
Before Seeding Instructions
Treated areas may be reseeded 1 week after application of Speedzone.
After Seeding Instructions
The application of Speedzone to grass seedlings is recommended after the second mowing. The application of Speedzone to newly sodded, sprigged, or plugged grasses should be delayed until 3 to 4 weeks after sodding, sprigging, or plugging operations.
Various sources state that SpeedZone does not need a surfactant. Environmental conditions and certain spray tank additives (eg. adjuvants, wettings agents, surfactants), liquid fertilizers, and tank mixtures containing other emulsifiable concentrates may reduce the selectivity on the turfgrass.
