Product details

Pennmag Turf Herbicide

For pre-emergent control of weeds in turf.

PENNMAG Turf Herbicide delivers effective control of various broadleaf weeds and grasses through an optimised formulation (S-metolachlor). PENNMAG has limited residual and does not affect new root development in turf production after harvesting or in sports field recovery after the winter season.

PENNMAG is safe to use on established and recovering turf. The product acts mainly through shoot (coleoptile) absorption. Its effectiveness depends on the occurrence of rainfall or irrigation to move it down into the top 3 to 4 cm of soil, where it must be present at the time of weed germination. If applying PENNMAG to warm season turf during the transition from winter to spring, avoid applications when soil temperatures remain low. Turf recovery will be greater if applied when soils have already commenced warming.


  • Optimised S-metolachlor formulation with 35% more herbicidal activity 
  • Pre-emergent control of various annual grasses and broadleaf weeds 
  • High safety to newly developing turf grass roots 


  • Minimal effect on new root development when growing back Buffalo Grass after harvesting and during recovery of sports fields after the winter season 
  • Perfect rotation partner for BARRICADE Herbicide
