Monterey Weed Impede 2-in-1 Concentrate is a unique non-selective herbicide because it contains both pre-emergent and post-emergent active ingredients. Glyphosate enters plants through foliage and works systemically through the roots to kill target plants, while Prodiamine creates an invisible barrier in soil to prevent development of new plants. Use Weed Impede on established annual and perennial weeds such as bluegrass, chickweed, crabgrass, goosegrass, mustard, spurge, bahiagrass, bermudagrass, clover, thistle, dandelion, and many more. Use as a pre-emergent for annual bluegrass, chickweed, carpetweed, pigweed, and other listed plants.

What is the Principle behind Weed Impede 2 in 1?
One ingredient enters the plant through the foliage and moves down into the roots, killing the plant. The other ingredient provides an invisible barrier in the soil, preventing growth and development of newly germinated weeds.

Works like a charm, especially on those tough stubborn perennials weeds and should be a staple in the tackle box of any ornamental landscape technician.

Love this product
By Jamie in Chandler, AZ on 11/02/2016
I have used this product for several and have not found anything that comes close to it! It kills the grass and weeds that are in my rocks and sidewalks and prevents new stuff .

Looks like a winner.
By Chris in Chandler, Arizona on 02/14/2017
It is still a little cool here, but I mixed up a small batch 5oz./gal.) and it worked quickly to eliminate all growing weeds. Planning on major application in a week or so (end of Feb.) and expecting pre-emerge to work as well as post-emerge did. I like the added dye to show exactly where spray is going. Looks perfect for a state where weeds grow all year 'round.
