SpeedZone is recommended for post-emergence broadleaf weed control in home lawns, golf courses, parks, commercial property, schools, sod farms, roadsides and cemeteries—especially where rapid visual results are an advantage.
SpeedZone contains an advanced chemistry. The mode of action inhibits a key enzyme in chlorophyll production. This causes cell membranes to rupture and rapidly disintegrate within hours. Weed death can occur within 7 to 14 days.
According to the company, university and cooperator tests show that applications have repeatedly controlled tough weeds like clover, plantain, ground ivy and spurge with a fast-acting, cool-weather response exhibiting injury within hours.
