Commercial Weed Control

What's the difference between a selective and non-selective weed control product?

  • Selective herbicide products are formulated to control specific weeds or weed categories. A material that is toxic to some plant species but less toxic to others.

  • Non-Selective herbicide products are formulated to control both broadleaf and grass weeds.



What is a residual weedkiller?

  • A type of weedkiller that leaves a barrier on the surface treated to prevent new germination for a period of time.
