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

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

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

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.

Would recommend this sunblock!
Size: 5 Fl Oz (Pack of 1)
Loved this sunblock for my stay abroad in the Caribbean. Left no white cast, and barely had any sunblock smell. Felt like a lotion if anything, and best of all, I didn't get burned! Would recommend.

It works
Size: 1.7 Fl Oz (Pack of 1)
I invested in this for its travel size and my needs for a product that would protect my skin and not make it feel super oily. This delivers!!! I used it for a week in Florida with UV up to 11 on some days and didn't face a single issue, even after a Disney day. I was almost in disbelief at how lightweight this product is for it to work properly, but the protection strength is fabulous. I don't burn in the sun, but if I do, its typically along my face where the bridge of my nose is or my upper cheeks. This product basically said, "not today, sun." Bonus, it didnt burn or sting my eyes all day in Disney parks heat, and I didn't need to reapply even though I brought it just in case. Maybe it was the product or the Disney magic, but my skin also didn't look oily or shiny at all in my pictures with the product offering a nice matte finish.

seriously matte-ifying
Size: 1.7 Fl Oz (Pack of 1)
Don’t judge but back in the day I used to use Avon’s “face perfector” because it REALLY cut down on the shininess of face oil and it also had SPF. It made your face look matte without any other makeup. And I am pleased that this gel is similar. No face grease. It’s not even really a gel—if instantly feels powdery (somehow?) in your hand, thus it’s nongreasy. It leaves your face shine free and protected.
