Product Benefits
  • For resistance management of Pythium Blight control, Subdue MAXX can be alternated with Heritage.
  • Low use rates: Small amounts are required to do the job.
  • Subdue MAXX can be used on all cool-season turfgrass species.
  • Subdue MAXX is highly soluble and will penetrate into the soil to give good root protection.
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

Class of Chemistry

Subdue MAXX contains the active ingredient Metalaxyl-M and its S-isomer at 240 g/L, formulated as a microemulsion concentrate (MEC.)

FRAC Group: 4


Turf Safety:

Experience has shown that strains of fungus resistant to Metalaxyl-M and S-isomer may develop. Failure to control the disease will result in crop damage and/or yield losses. Any fungal population may contain individuals naturally resistant to Subdue MAXX and other Group 4 fungicides. A gradual or total loss of pest control may occur over time if these fungicides are used repeatedly at the same use site. Appropriate resistance-management strategies should be followed.
