Pac-Down is a suspension concentrate formulation for spray application under dilution with water for the suppression of Winter Grass (Poa annua) in turfgrasses including Bentgrass, Perennial Ryegrass, Kentucky Bluegrass, and Green Couch.

Pac-Down has been discontinued and replaced by ProForce Regulate 200SC Plant Growth Regulator.

Apply to dry or wet turf and water in immediately with 4-6 mm of sprinkler irrigation.

General instructions for Pac-Down Plant Growth Regulator

The degree of Poa annua control will be influenced by application rate as well as the turf management practices, climate, soil type, grass variety, and Poa annua biotype.

Growth of Poa annua will be reduced 1-2 weeks after application. Higher application rates will cause Poa annua to discolour (yellow to brown) and stop or slow its growth allowing desirable turf species to dominate.

Application 1-2 weeks prior to Poa annua seed-head emergence will reduce seed-head visibility, but not formation.

Repeat application 4-8 weeks apart (depending on rate) are required where Poa annua content is high.

Use in areas containing greater than 70% Poa annua will result in widespread discolouration of the fairway and green and may not appear acceptable to the user. Use of other cultural techniques are encouraged to lower the percentage of Poa annua below the 70% level.

Over-seeding is recommended to hasten the conversion from Poa annua to more desirable grasses. To avoid stunting the growth of desirable seedlings, allow at least 14 days after treatment before overseeding and in newly over-seeded areas. Make treatments at least 6 weeks after over-seeding. On new grass plantings delay application until after establishment. Delay planting grass seed until after heavy rain or watering and not sooner than 1 month after application.
