ArborPGR 22.9 SC

ArborPGR 22.9 SC is applied as a soil drench or soil injection and is labeled for two primary use cases: trees and non-residential turfgrass.

For trees, apply as a basal drench or soil injection near the trunk at the soil interface. Basal drench applications involve pouring the diluted mixture into a shallow 2-inch furrow around the base of the tree. Soil injection applications should be placed 3–6 inches deep using equipment capable of 60–150 psi. Dosage is determined by trunk diameter (DBH) and tree species group — the label provides rates for over 100 tree species organized into six groups, covering trees from 4" to 50" DBH. Applications can be made year-round when soil is not frozen or saturated. Maximum growth inhibition may not be fully visible for up to 18 months. Do not reapply until symptoms from the previous application begin to disappear, or within 3 years.

For non-residential turfgrass, apply at 0.10 to 0.75 lbs. active ingredient per acre (6.4 to 48.0 fl oz product per acre) depending on grass type. Warm-season grasses (bermudagrass, St. Augustinegrass) use 0.50–0.75 lbs. a.i./A. Cool-season grasses use 0.25–0.50 lbs. a.i./A. Bentgrass putting greens and overseeded bermudagrass use 0.10–0.25 lbs. a.i./A. Apply uniformly with pressurized spray equipment and water in within 24 hours with 0.25 inch of water. Mowing frequency can be reduced by up to 50% for 6–8 weeks. ArborPGR also suppresses Poa annua growth and competitive ability within 1–2 weeks of application. Do not apply more than 4 quarts per acre per year.

Always read and follow all label directions prior to use. Refer to the product label for complete dosing tables, species groups, and use restrictions.
