Subdue Maxx Fungicide

Subdue Maxx fungicide is in a microemulsion concentrate that controls pythium blight in cool season grasses like bluegrass. It contains Mefenoxam that has been a time-tested material that have proven to be very effective against Pythium blight.

Pythium Blight is common when there is hot and humid weather, especially when night temperatures are above 68°F. Subdue Maxx is a microemulsion formulation that acts as a systemic traveling throughout the entire plant. It has excellent tank mix compatibility with easy mixing and is odorless.

For more information on Pythium blight, see Pythium Blight-Purdue University

Subdue Maxx is labeled for application as a foliar spray, soil surface spray or soil basal drench. It may be used in various applications such as commercial and residential landscapes, greenhouse and field-growth nursery plants, containers, non-bearing fruit and nut trees, botanical gardens and other non-residential landscapes.

How Subdue Maxx Works

The active ingredient, Mefenoxam 22%, inhibits ribosomal RNA synthesis and inhibits the pathogen at various stages in its life cycle; mycelia growth and spore formation stages.

Resistance Management Recommendations:

  • Subdue MAXX is a systemic fungicide having a specific mode of action. Use of Subdue MAXX could result in development of insensitive strains of fungi. Development of insensitivity cannot be predicted. Consult with your State Agricultural Experiment Station or Extension Service Specialist for guidance and ways to control any possible Subdue MAXX insensitive strains of fungi which may occur.
  • The active ingredient in Subdue MAXX is mefenoxam, a Group 4 fungicide (phenylamide). Some disease pathogens are known to have developed resistance to fungicides used repeatedly for their control. To prevent the development of insensitive strains of fungi to mefenoxam, apply Subdue MAXX in an alternation or tank– mix program with fungicides that are not in Group 4 and to which pathogen resistance has not developed.
  • Applications targeted for downy mildew diseases should always be in a tank mixture with a non-Group 4 fungicide. For foliar applications to ornamentals and conifers, do not make more than one (1) application before alter- nating with a non-Group 4 fungicide for sequential foliar applications. For all other applications, do not make more than two (2) sequential applications of Subdue MAXX before alternating with a non-Group 4 fungicide. An example of a sound resistance management program would include two (2) Subdue MAXX applications (one could be a foliar application) followed by two (2) non-Group 4 fungicide applications.
