Resolute 4FL Herbicide is for selective pre-emergent control of grass and broadleef weeds that are in established turfgrasses (not including golf putting greens), sod nurseries and lawns; field-grown, landscape and container ornamentals; established wildflower and perennial plantings; and christmas tree farms. It stops weeds from continuing to grow and stops newly germinated weeds. A spray colorant may be used with this product to minimize overlaps.

Cost Effectiveness:
Covers 116364 - 556521 square feet
at a cost of
$0.26 - $1.26 per 1,000 sqft
Instructions:
In many areas a single application of 21-48 ozs./A of Barricade 4FL will control goosegrass. However, under heavy goosegrass pressure and/or an extended growing season, weed control will be most effective by making an initial application of 21-26 ozs./A followed by a second application 60-90 days later. Note: Do not exceed the maximum rate for the turf species listed in the Maximum Application Rates Table.
