Product Overview

Proxy Growth Regulator helps in managing the growth of desirable grasses in cool-season turf while suppressing Poa annua and white clover seedheads. Its unique formulation will not induce initial shock or cause growth surge after application, plus it offers a lesser chance of phototoxicity compared to other growth regulators. It helps control growth around greens and tees, bunkers, and hard-to-mow areas, reducing labor time for more efficiency. This formula also helps establish a denser and tighter-knit turfgrass to make it more durable. Labeled for use on golf courses including greens, tees, fairways, and roughs, commercial turfgrasses including Kentucky bluegrass, bentgrass, tall and fine fescue, perennial ryegrass, parks, and sports turf. It rainfast in about 2 hours so it stays effective after rainfall.

Tank Mixture with primo MAXX: Tank mixtures of Proxy Growth Regulator at 5 oz. per 1,000 sq. ft. and Primo MAXX at 0.125 or 0.25 oz. per 1,000 sq. ft. can be used to promote seedhead suppression as well as turfgrass quality.

Follow the recommendation on each product label for the most restrictive application interval for each turfgrass. Application of this tank mixture during frost periods may cause temporary turf discoloration.
