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

  • Economical alternative comparable to Barricade® 4L

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.

Flavorful and good quality
Size: 1 PT, Size: 1 PT
Flavorful, big, and overall good quantity! Out of 2 pints, maybe 3 berries were squished... which is better than most grocery stores I've experienced. I wasn't sure what to expect from Amazon delivery blueberries, especially for the amazing price of $0.79 per pint. They were delivered in an insulated foil-lined paper grocery bag with a frozen bottled water inside to keep them cool. The pints were closed with rubber bands around them to minimize spills. I opened the bags within a few minutes of delivery so I cannot say how cold it would stay if I didn't bring it inside immediately, but the frozen bottled water was only slightly melted upon delivery so they had kept well.

Sweet, big and fresh
Size: 1 PT
I do almost ALL of my shopping on Amazon ! I live within 5 miles of a huge Amazon warehouse! I’m almost 70 and I know what I like! I realize I depend on the reviews when I make any purchases. Therefore… I am going to get better at reviewing and leaving my opinion on my purchases! These are the sweetest, biggest, freshest blueberries that I can find anywhere! I have picked up a popular brand on occasion when in my favorite grocery stores and they are smaller, tart and go bad too quick. Treat yourself and buy these blueberries from Amazon fresh!

Tasteless and made in Peru. Won't be buying again because in Peru they use chemicals that have been banned!

I know where the sugar is
Size: 1 PT
I will say these are not only very large but that they are pretty tart. To me they are somewhat like a blue rasberry sucker. They seem pretty fresh. They were not mushy at all, very firm but not hard. They look pretty clean also. I would repurchase since I know where the sugar is and where the muffin recipes are.
