How is ThatchZyme different from all the other products claiming to reduce thatch?

Sprayable ThatchZyme works as a program to deliver the first field tested and proven enzyme for degrading thatch and organic matter in turfgrass.

What’s in ThatchZyme?

ThatchZyme works because it contains the unique and crucial Laccase enzyme, shown to break down lignin and thus accelerate thatch decay.

Is there any academic research on ThatchZyme?

Yes, researchers have spent over a decade in research developing and then proving the effectiveness of Laccase for breaking down thatch.

Has ThatchZyme been field tested?

Yes, ThatchZyme has been tested ongoing to confirm its benefits for turfgrass managers.

Is ThatchZyme a living organism?

No, ThatchZyme harnesses microbes during manufacturing to make, extract and concentrate the bio-active Laccase enzyme. Doing so ensures the right rate of Laccase is being delivered in every spray vs. others who try applying live microbes which in order to work would first have to overcome the huge hurdles of survival, persistence and competition in order to possibly produce the correct thatch degrading enzymes at high enough concentrations to work.

What happens if ThatchZyme dries on the leaves, and how much do I have to water it in?

No problem, drying will not affect ThatchZyme after it’s been sprayed, just water it into the thatch zone when you can before the next mowing.

How often do I use ThatchZyme?

ThatchZyme works in a monthly program and you will want to apply it for three months, it can be applied more frequently (bi-weekly) and rates/intervals can vary based on whether one is managing thatch ongoing or trying to correct a large thatch layer issue.

Can I mix ThatchZyme with other products?

Yes, it is not affected by other common tank-max components such as fertilizers, surfactants and pesticides.

Is there a turfgrass phyto risk?

None that we’ve seen up to 4x our 1qt/A rate.

Any limits on when I can use ThatchZyme?

The laccase enzyme will be active at any temperature above freezing and its activity increases with higher temperatures, as does the surrounding microbial activity.

How do I tell if ThatchZyme is working?

You can take thatch thickness profile measurements before and after treatments to observe changes over time, likewise OM testing is useful.
