We Answer Questions About 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.
