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.

  • 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

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.

Really works and it's safe.
Color: White, Size: 0.15 Ounce (Pack of 1)
I am a flats fisherman – this stuff really works, it's smooth, flavorless, reef-safe, and safe to lick. Reapply as often as you remember to.

Highly recommend. Any graininess and whiteness are minimal and insignificant.
Color: Blanco, Size: 0.15 Ounce (Pack of 2)
This is the best mineral(non-chemical) lip sunscreen I have found. Highly recommend. The first few times I used it, it felt ever so slightly grainy. Maybe the graininess rose to the top. Even if it was grainy all the way through, I would still recommend. There is a slight whitish cast to your lips-not noticeable or significant in my opinion. There is a very minimal flavor and it has a nice feel on your lips.

A must have for your summer bag
I am 100% devoted to Blue Lizard products! I got some extra sun and needed relief, fast. This non-greasy nor slimy cream is exactly what I didn’t know I was looking for. I had applied aloe alone to my skin and received no relief. Within minutes if not seconds of applying this, I had noticed improvement. The consistency is not too thick or too thin, it absorbs into the skin nicely and can be reapplied without getting cakey. It gave my sunburn relief while also moisturizing the skin. I haven’t peeled at ALL. I love that it has clean ingredients and a neutral fragrance. My skin is so sensitive, so having natural ingredients is a plus. Blue Lizard After Sun is now my holy grail and I will recommend it over and over.

HANDS. DOWN. AMAZING.
I have used other products for after sunning in the past. This stuff is AMAZING and I wish I could be a spokesperson for it. I am extremely fair skinned and used this on my vacation at the beach. I used some spf which always leaves me slightly red. I put this on every night and the redness was gone by morning! I was ready to hit the sun again! It doesn’t have a scent and doesn’t leave a sticky lingering feeling or weird smell either. Just moisturizing and safe for my acne prone skin. I will buy this and use this forever!!!!

Phenomenal.
Got a baaaaad sunburn from head to toe. On day 2 or 3, I finally got this stuff. It took the sting away quickly. No smell, and it feels nice on the skin. It’s thin and spreads well. Definitely helped keep my burns moisturized - I didn’t even peel, save for the blisters on my shoulders. My boy even let me put it on his pink little cheek, and
