How it works

ThatchZyme is the first proven sprayable tool for managing thatch. It harnesses the power of Laccase, a well-researched thatch-degrading enzyme, to accelerate the breakdown of thatch. 


Laccase works at the molecular scale by targeting lignin—the tough, slow-to-decompose part of thatch. While soil fungi naturally produce Laccase, its production is suppressed by nitrogen fertilization and other cultural practices leading to concentrations too low to keep pace with the rapid buildup of turfgrass thatch. 


ThatchZyme solves this deficiency by supplying an effective dose of this crucial enzyme into the thatch zone. The result? Effective, non-disruptive thatch management that integrates seamlessly into your existing spray programs.

How to use

Spray ThatchZyme monthly at 1 quart per acre during the active growing season and for managing thatch. It harnesses the power of water after application to get the enzymes in contact with the thatch/OM zone.


ThatchZyme is compatible with common liquid fertilizers, surfactants, and soil sprays. We recommend three consecutive monthly applications to begin. The best results are obtained from season-long spray programs. We recommend evaluating performance by performing OM246 soil testing and evaluating visual changes using a flat soil profiler.
