Weed Impede® 2-in-1 Pre-Emergent and Post-Emergent Non-Selective Weed Control

Double the power! Works as a systemic post-emergent herbicide and also as a pre-emergent barrier to germinating weeds—use for broadleafs and grassy weeds!

Two products in one! Quart covers up to 10,666 sq. ft. while gallon covers up to 42,666 sq. ft. Primary portion of this combination herbicide delivers the active ingredients through the foliage and moves systematically to the roots, killing the weed. The secondary portion functions as an invisible barrier on the soil preventing the development of weeds. (Active ingredients 40.15% Glyphosate and 7.51% prodiamine).

Use around established landscape plantings, on gravel areas, along edges of lawn and fence lines, crevices, cracks, driveways, sidewalks and patios. Add 3 to 6 fluid ounces to 1 gallon of water and treat 1,000 sq. ft.

Best weed killer for Arizona's big weeds! 10 Stars......


We have a vacation rental house in Southeastern AZ and it must look neat at all times. This product is it! We have a bad weed called Pig Weed that grows 7 foot tall with a thick staff. Using this product, we don't see it coming up where we have applied it. Woo Hoo. We also have a 1000 ft rock driveway which is free & clear of all weeds for the 1st time ever! I didn't even have to reapply in July. Make sure you put this down the end of March/ April to start off the season! Thank you for selling this great weed killer!
