Built on What Works: A Decade of Performance with Prudent Products

A solid focus on what works is where Chris Knapp dedicates his time. He doesn’t chase turf management trends — he looks to the products and formulations he has relied on for over a decade: Prudent^® products, including a urea phosphite fertilizer for turf.

“I have been using Prudent 40Plus (and Prudent 44) for the last 10 years,” he says.

In golf course management, performance isn’t measured by one application — it’s measured by quality greens over the course of the year. As Superintendent at Amherst Country Club in New Hampshire, Knapp has relied on Prudent products, including Prudent 40Plus, across the two facilities he’s managed.

He shares that he first tried Prudent 40Plus in an effort to solve a common challenge in golf course turf management programs.

“I first started using it because of some mixing incompatibilities I found I had with some other products I like to use,” he explains. “I was happy with it being a urea phosphite over a potassium phosphite, and also happy with the usage rate, which was much lower than some of the other products I use, so less product filling up my storage.”

What Knapp found was a product that fit seamlessly into his program.

Prudent 40Plus is built on urea phosphite technology and offers a different approach compared to traditional potassium phosphite products. As a urea phosphite fertilizer for turf, the formulation is designed for improved uptake and mobility within the plant. Prudent 40Plus is formulated to support plant health through improved nutrient movement and the inclusion of amino acids that help turf respond to stress.

For superintendents managing high-performance golf course turf, that added support can make a measurable difference under pressure.

And for Knapp, the long-term results speak for themselves.

“If another turf manager asked me about Prudent 40Plus, I would highlight what stands out to me: easy to mix, less space to store, urea phosphite so it should have optimum mobility in the plant, and then I would say it also works great. I have not had any pythium or soil-borne disease outbreaks in the last 10 years,” he says, and he adds,

“I followed up with my own trial in two approaches that were side by side, and Prudent 40Plus definitely had a positive effect on the turf it was applied to that was superior to its competition.”

For Chris Knapp and industry professionals like him, success is about building a program around solutions like Prudent^® products that consistently deliver on golf course turf — year after year.
