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.

Poli cleaners.
Material Type: Powder Ox, Size: 16 oz
Our trailer was extremely oxidized. I used the Poli wash and fiberglass cleaner, super easy. It removed the oxidation and made our trailer look new again. Next I will try the Poli sealer.

Works OK.
Material Type: Powder Ox, Size: 16 oz
With a lot of work and diligence (elbow grease), the product works at removing oxidation. I expected it to easily remove the old Poliglow as well. Still lots of work. It will NOT remove the brown water stains from the roof of my molded fiberglass camper. Product is OK, but does not work as easily as advertised.

It's extremely difficult and when it hasn't been maintained it looks like skin peeling after a sun burn

Poli-glow definitely works. The negative feedback is generally due to someone trying to remove poli-glow. It's extremely difficult and when it hasn't been maintained it looks like skin peeling after a sun burn. I purchased a 41' sailboat with poli-glow. The poli glow was flaking off and had to be removed. It wasn't fun. In the end, I bought poli-strip and used an orbital sander and wet sanded thru it. Then I used poli-strip, then poli-prep and washed it down. From there I used poli-ox and poli-prep one more time...I basically used poli-prep along with lots of water to wash boat down. The poli-ox when used thick, like a paste, ate through most stains once poli-glow was removed. It took two-three days of prep. Application took half day per side. I used two kits. Also bought the rectangular special applicator (far better than their mitt). Make sure to have lots of disposable gloves. I don't think the chemicals will harm your hands much...I didn't have gloves for much of the prep work, but gloves are a must when applying poli-glow. Othnerwise your hand get very gunked up.
