PGR programs: a GCI study

GCI surveyed nearly 300 superintendents, chosen randomly from our circulation list, about what part plant growth regulators (PGRs) played in their maintenance programs. The vast major of superintendents indicated they did use PGRs, spending on average about $5,175 on products. And despite the challenging economy and financial stress on maintenance budgets, nearly half (47 percent) report PGR spending has remained consistent.

Do you use PGRs (plant growth regulators) as part of your maintenance program?


5% - No
95% - Yes

How has your total annual maintenance budget changed over the past three years?


    1%    More than 20% increase   
    1%     16% to 20% increase   
    3%     11% to 15% increase   
    12%     6% to 10% increase
    17%     1% to 5% increase   
    19%     No change

As a regularly-scheduled component of their overall maintenance program, superintendents primarily use PGRs for smoother putting surfaces and for overall turf health on greens and fairways.

Where do you use PGRs? 


25%     Greens only  
2%     Fairways only   
60%     Greens and fairways   
13%     Greens, fairways and roughs

How do you use PGRs?


88%     Regular application schedule developed in advance  
20%     Apply on an as-needed basis   
 6%     Spot usage

Have you been satisfied with your PGR’s performance?


5% - No
