Building a spray program can be stressful. You’re thinking about pest control, fertility, PGRs, wetting agents, and plant health products. Are products from the last application still doing the job? Then comes the mixing math. A misplaced decimal or a wrong unit can turn a routine application into a very uncomfortable conversation at the next Greens Committee meeting.
Mistakes happen. Not because turf managers are careless, but because spray programs involve a lot of moving parts, numbers, and uncertainty around future weather, pest pressure, and growth rate.
GreenKeeper App is a cutting-edge decision-support tool built around a simple core: helping you build and execute an effective spray program. That reliability is why 97% of GreenKeeper subscribers renew every year, why our user base has grown internationally, and why more than 50+ of the Top 100 U.S. golf facilities and PGA Tour events count on GreenKeeper for tracking every application.
Application Advisor to Select Pest Control Products
Pest control is the foundation of most turf spray programs, but it is also difficult to stay up to date. New products hit the market every year, university trial data keeps evolving, and what worked best two seasons ago may not be the top performer today.
GreenKeeper’s Application Advisor pulls from independent and university research trial data to show you which products are the most effective against specific pests. Compare product performance across multiple pests, filter by what’s in your inventory, and review past applications to make a confident selection. Rotation icons flag chemical classes so you can see whether you’re rotating properly.
Once a product is selected, you can view the label in GreenKeeper, decide on an application rate, and lock in the re-application interval. Everything you need to make the best decision is in one place.
Mixing Math Guidance and Flexibility
GreenKeeper gives you flexibility when building an application. Configure tanks as full and partial tanks or split them evenly for simpler mixing math. GreenKeeper stores different sprayer setups depending on the mission — greens versus fairways or foliar versus water-in applications.
You can work in either direction. Enter a target rate and GreenKeeper calculates product needed, or specify a product amount and back-calculate the rate. That second option is especially useful for fertilizer applications where applying a full 2.5-gallon jug or 5 lb bag to a sprayer tank can be more practical than setting a specific application rate.
Liquid fertilizers add mixing math complexity because volume doesn’t tell you much about nutrient load. GreenKeeper handles that conversion automatically, giving you a clear nutrient summary when you finalize the application.

Proprietary Models for PGRs and Wetting Agents
With pest control and fertilizer, you usually know if something is working — a pest is controlled or the turf responds visually. PGRs and wetting agents are harder to read. Performance depends on temperature, application rate, grass species, and mowing height. Without a non-treated control plot, it’s genuinely difficult to know what’s happening in the field.
GreenKeeper has been pioneering PGR performance models for two decades. With over 700 growing degree day models spanning different active ingredients, grass species, and mowing heights — combined with observed, forecast, and long-term normal weather data — GreenKeeper tells you how a PGR is going to perform in the future.
When PGRs and DMI fungicides are applied together, their combined effect on clipping yield suppression cannot be found on a product label or GDD tracking website. GreenKeeper is the only platform that understands these interactions in real time, and for most of our users, it’s the most valuable guidance we provide.
Wetting agent longevity declines as air and soil temperatures rise through the season. GreenKeeper’s wetting agent models account for that variability, giving you confidence that your program is maintaining soil wettability when it matters most without making costly unnecessary applications when it doesn’t.
Inventory Automation and Pesticide Reporting Compliance
Nobody enjoys managing inventory, but club managers and controllers increasingly want visibility into what’s being used, when, and what it costs. GreenKeeper keeps that information current without extra work. Product costs are visible while building an application, and once it’s logged, inventory levels adjust automatically. The Analytics page gives you a clear view of chemical expenses over time.
GreenKeeper also captures weather conditions during an application and pairs them with regulatory information to generate compliant pesticide and fertilizer records automatically. When an Ag Inspector shows up, your records are complete, accurate, and ready. No scrambling, no reconstructing application logs from memory.
Get Started by Logging Your First Application
Turf managers have to select products, do the math, and keep up with inventory and compliance reporting regardless of what tools they use. GreenKeeper makes all of that easier, and the best way to experience it is to simply start logging applications.
Every application you log triggers GreenKeeper’s advanced models in the background. PGR and wetting agent performance curves update. Inventory adjusts. Compliance records generate. The more you log, the more the platform works for you.
There’s no complicated onboarding required – but we will provide free training if you’d like. Pick a product, set the application rate, log the application, and watch the value build from there.
