Product Overview

Cool Power Selective Herbicide is a specially formulated liquid herbicide that’s specially designed for cool-weather weed control. It’s perfect for dormant warm season turf, winter weed control, and early season applications in transition zones and cool season climates. It contains a combination of three active ingredients: MCPA, Triclopyr, and Dicamba which provides an effective post-emergent control of chickweeds, dandelions, oxalis, plantains, spurge and a wide range of broadleaf weeds. It’s compatible with most liquid fertilizers and can be used in 2, 4-D sensitive areas. It can also be used on ornamental turf lawns (residential, industrial and institutional), parks, cemeteries, athletic fields, golf courses (fairways, aprons, and roughs), non-crop areas, and similar turf areas.

Apply Cool Power Selective Herbicide at the rate of 2-1/2 to 3-1/2 pints in 20 to 240 gallons of water per acre (0.91 to 1.29 fluid ounces in 1/2 to 55 gallons of water per 1,000 square feet) to control weeds growing in turf planted to bluegrass, fescue, rye, bent (excluding golf greens and tees), bahia, bermuda, and zoysia.

When treating warm season turf that is completely dormant, the higher rates may be used. When treating warm season turf that is actively growing, use a lower rate. Avoid applications to warm season turf during transition from dormancy to green-up or green-up to dormancy.

Herbi Controlled Droplet Applicator:

Add 1-2/3 to 2-1/2 pints of Cool Power to the 5 pint Herbi bottle, then fill with water to make 5 pints of mixture or substitute 1/2 pint of a surfactant for water while agitating the solution.

While walking at approximately 1 pace (3 feet) per second, spray entire contents over 33,000 square feet (3/4 of an acre). Do not overlap (double coverage) at edge of spray patterns. Reduced rates (use 1/2 of rate shown above) of Cool Power must be applied when grass is stressed from heat, drought, etc.

Controlled Droplet Applicators - (CDA), Atomizers, and Spinning Disk Applicators:

Use Cool Power at 2-1/2 to 3-1/2 pints per acre (0.9 to 1.25 fluid ounces per 1,000 square feet) in sufficient water to assure coverage (1 to 4 gallons of water per acre is normal for this type of equipment).

NOTE: For all grasses (1) Do not overlap spray patterns; (2) Use reduced rates if grass is stressed from heat, drought, etc.; and (3) Follow CDA equipment spray instructions.

Roadsides (Including Aprons and Guard Rails), Rights-of-Way, and Other Similar Non-Crop Areas:

For the control of broadleaf weeds, mix at a rate of 1/4 to 3/4 gallon of Cool Power per 50 to 300 gallons of water. This mixture will cover 43,500 square feet. Thoroughly saturate all weeds with spray mixture. Apply any time between the time when plants come into full leaf (Spring) to when the plants begin to go dormant. Best results are obtained when weeds are young and actively growing. Do not cut weeds until herbicide has translocated throughout the plant causing root death. For small broadleaf weeds, use the lower rate. Heavy, dense stands require the higher rate of 3 ounces of Cool Power per gallon of water and spray to thoroughly wet all foliage.
