Mode of Action

Subdue MAXX stops pathogen growth by inhibition of nucleic acid synthesis. Subdue MAXX enters the turfgrass in two ways:

  • By Systemic Action - Subdue MAXX is absorbed the roots and translocated throughout the entire turfgrass plant where it lasts up to three weeks. Subdue MAXX cannot be washed off by rain because it is inside the plant.
  • By Contact Activity - Some of the Subdue MAXX remains on the surface of the soil and is absorbed onto the soil particles and organic matter, where it controls pathogens on contact.

Mode of Action: Inhibition of nucleic acid synthesis
