Real Course Results with ThatchZyme

Phil Dwyer, VP Sales & Marketing • November 12, 2025

Philip Beaver, Tipton Golf Course, Tipton, IN. Golf Course Superintendent, speaks about his first experience with using ThatchZyme.

How did you first trial ThatchZyme?

ThatchZyme at .8oz/M/biweekly on greens for the growing season. Objective was to "curatively" reduce OM in greens to see if we can skip our regular large hollow aerification. We've done double verticutting and sand topdressing. We'll know next year how well they hold up.

How did you measure thatch/OM changes, were there any other related turfgrass responses observed by you or others?

Disappointingly, we didn't measure OM. However, there is a reduction in OM layering from old inconsistent cultural practices as well as a nice uptick in firmness. My clientele has complained of being too firm which means the greens will likely hold up to heavy rain events. Will know more after using again.

Overall, how did the product perform per your goals/expectations?

The product has lived up to the hype. We'll see if it surpasses expectations next year.

Any other insights or recommendations to share with fellow turfgrass managers considering using ThatchZyme?

It's a product worth trying. I'll know for sure next year.

There’s More Value in Your Corn Residue Than You Think

By Stephanie Wedryk, Ph.D. • September 8, 2026

Corn residue can decompose slowly because lignin gives stalks and leaves their rigid structure. TillZyme™ uses laccase enzyme technology to help accelerate the breakdown of tough crop residue.

Break it Down with TillZyme

By Stephanie Wedryk, Ph.D. • September 2, 2026

After harvest, crop residue is not just leftover stalks and leaves. It is an active biological system that adds nutrients to the soil, increases organic matter, and builds better soil structure for next year. Actively managed residues help create a favorable seedbed for better stands and yield. The enzymes produced by fungi accelerate the process by breaking down tough lignin before naturally occurring soil microbes take over. Learn more here .
