Quali-Pro® Prodiamine 4L is a professional-grade liquid pre-emergent herbicide designed to provide season-long control of many annual grassy and broadleaf weeds. Formulated with 40.8% prodiamine, this flowable concentrate helps prevent weeds from establishing by stopping newly germinating seeds before they develop.

Ideal for use on established turfgrass, lawns, ornamentals, sod farms, and Christmas tree farms, Prodiamine 4L helps control problem weeds such as crabgrass, annual bluegrass, chickweed, henbit, knotweed, foxtail, and spurge. Its low solubility and low volatility allow it to remain in the weed germination zone for extended protection. This formulation provides reliable performance with low use rates and a low-staining formulation.

Product Details

  • Professional liquid pre-emergent herbicide for turf and ornamental areas

  • Contains 40.8% prodiamine (4 lb per gallon)

  • Provides season-long control of many grassy and broadleaf weeds

  • Controls weeds such as crabgrass, Poa annua, chickweed, henbit, foxtail, spurge, and knotweed

  • Low solubility and volatility help keep the product in the weed germination zone

  • Low-staining formulation

  • Suitable for lawns, landscape ornamentals, sod farms, and Christmas tree farms

How It Works

Prodiamine 4L works as a pre-emergent herbicide by inhibiting cell division in newly germinating weed seeds. This prevents weeds from establishing in treated areas.

For effective activation, approximately 0.5 inches of rainfall or irrigation is required after application to move the product into the soil where weed seeds germinate.

Good material but bites back
Size: 20 sqft
Very good product for my rear trunk and backseat on my mustang. I would recommend some type of gloves due to the foil itself when placing down will cut up your hands and fingers. Overall good product for its price.

No more scrolling. Best price, abundant, does its job.

I have it under the closed cell foam. It’s great. Just as great as Killmat and all the other butyl rubber products. Let me ask you to do something: look at the people who rated it 1 and 2 stars. No reviews. No pictures. Why? They don’t want to see the most budget friendly product getting sold. That’s some weak business. Rest assured you’ll be happy with this. Why did I buy both types? Butyl rubber helps the car not be a tin can. It keeps the outside road vibrations out. Closed cell phone keeps your music in. They work best together., Kumbaya, we have unity! We can get along, even in this age in time. The closed cell foam is cheap. You’ll get it to replace the nasty cloth under your carpet. Do the knock test. It won’t help. You need this too. And truth be told, I prefer that it has no name on it. I’m not paying money so you can brand yourself on my car. Ps: these products go on and don’t come off. Don’t mess up. It’s the same for the competitors and the closed cell foam. One shot. Do it right the first time. I’m writing this review after I used up my first box and am getting more. Happy returning customer.

Great stuff, well made.
Model: 36 Sqft
I was very pleased with this product. Very easy to use, flexible enough to conform to the variations of the surface (floor of the car and some side panels), and it stuck well. I topped it with a similar foam product to provide additional sound deadening. The car has not been run yet but the panels are much "quieter" when tapped on vs before with undercoating, felt and carpet. Seems well made and I expect no issues in the future.
