ThatchZyme FAQ
Phil Dwyer, VP Sales & Marketing • June 17, 2025
  • How is ThatchZyme different from all the other products claiming to reduce thatch?

    ThatchZyme is the first enzyme-based spray proven in the field to actively break down thatch and organic matter. Unlike microbial products, which rely on live organisms to survive and perform in unpredictable soil conditions, ThatchZyme delivers a reliable, measurable dose of active enzyme every time you spray.

  • What’s in ThatchZyme?

    ThatchZyme is powered by Laccase, a specialized enzyme that breaks down lignin. the tough, decay-resistant material that binds thatch together. Laccase works by opening up the thatch structure, making it easier for natural microbial activity to complete the decomposition cycle. The result: less mechanical disruption, improved playing conditions, and a more efficient thatch management program.

  • Is there any academic research on ThatchZyme?

    Yes. Laccase has been the subject of over a decade of academic and applied research confirming its role in lignin and thatch degradation.

  • Has ThatchZyme been field tested?

    Extensively. It has been tested across a variety of turfgrass systems to confirm both safety and effectiveness for turf managers. See our data here.

  • Is ThatchZyme a live biological product?

    No. ThatchZyme is not a live organism. Microbes are used during production to create and concentrate the Laccase enzyme. By formulating only the active enzyme, ThatchZyme delivers precise, predictable results without the variability of live biology.

  • What if ThatchZyme dries on the leaf surface? Do I need to water it in immediately?

    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 should I apply 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 tank mix ThatchZyme with other products?

    Yes. ThatchZyme is compatible with most fertilizers, surfactants, and pesticides commonly used in turf management. As with any tank mix, we recommend performing a standard jar test to confirm compatibility before full-scale application.

  • Is there any phytotoxicity risk?

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

  • Are there seasonal limitations to using 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 can I tell if ThatchZyme is working?

    Monitor changes in thatch thickness over time using core samples or profile measurements. Regular organic matter (OM%) soil testing is a key tool for tracking progress and should be used alongside visual assessments of the soil profile.
