Pin-Dee 3.3 T&O, Oil-based Herbicide - Professional Preemergent Weed Control for Turf and Ornamentals

Pin-Dee 3.3 T&O Herbicide delivers long-lasting preemergent weed control for managed turfgrass, ornamental plantings, and landscapes. Formulated with pendimethalin in an oil-based, emulsifiable concentrate (EC) formulation, Pin-Dee 3.3 T&O offers dependable, season-long residual control of annual grasses and small-seeded broadleaf weeds in high-value turf and ornamental settings.

Warning: this product will stain surfaces it is applied to for much longer than Prowl or Satellite. Be careful spraying around porous areas such as asphalt, concrete, or other decorative areas.
