Combines the three active ingredients recommended for maximum plant growth regulation benefits - mefluidide, imazethapyr and imazapyr. This combination has been proven in university testing to provide maximum growth control and seedhead suppression. Now for the first time, these ingredients are available as a premixed product for maximum cost effectiveness and minimum hassle for industrial growth management programs.
Stronghold PGR can stretch your maintenance budget, while keeping treated turfgrass areas looking neat and trim with minimal attention. It can be mixed with Hi-Dep® IVM Broadleaf Herbicide to control broadleaf weeds, saving the cost of a separate herbicide application.
Applied early in the spring - ideally within 4 weeks of initial green-up of tall fescue and Kentucky bluegrass - Stronghold will inhibit seedhead development. Plant energy which is normally used in the development of seeds and stems is retained and available for root development, causing grasses to look greener and healthier after the PGR effect wears off.
Many managers of low maintenance turfgrasses have indicated that it is the seedheads that cause the grass to look ragged, unkempt and off-color; where seedheads are eliminated the grass can grow tall and look attractive longer without mowing.
