What is CDU?

Did you know that Turf Trust® with CDU supports NATURAL suppression of lawn diseases?

TURF TRUST® contains an array of controlled release nitrogen sources, formulated to feed slowly and gently through all weather conditions.  TURF TRUST® is the only brand with Crotonyliden diurea or CDU.  CDU is a unique form of Water Insoluble Nitrogen (WIN) that is released through microbial action.


Aerobic bacteria feed on CDU, converting it to the nitrate form, making it available to plants. CDU provides a food source that allows the population of aerobic bacteria to soar.  At soil temperatures above 53 degrees F, the same microorganisms that feed on CDU also feed voraciously on the very spores that can create the lawn diseases brown patch, fusarium and pythium.


Over time, feeding your lawn with TURF TRUST® with CDU supports the continued growth of a microbial population that can minimize outbreaks of lawn diseases without additional fungicide and pesticide applications.


Feed your lawn with Turf Trust® and prepare to be amazed!
