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.

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.

Will never use another moisturizer
Size: 16.9 Fl Oz (Pack of 1), Size: 16.9 Fl Oz (Pack of 1)
I will never use another moisturizer again. I have highly sensitive, allergy-prone skin, and this is hands-down the best moisturizer I have ever found. It provides deep, long-lasting hydration that actually stays with you throughout the day. I also suffer from Keratosis Pilaris (KP), and this lotion has worked wonders for clearing up and smoothing out those stubborn bumps. It comes in a giant bottle that lasts a long time. The lotion itself is quite thick, so it feels slightly greasy for a brief moment right when you apply it, but it soaks in incredibly fast. Amazingly, despite how rich and thick the formula is, it has never clogged my pores or caused breakouts. If you have dry, sensitive, or bumpy skin, you need to try this!

Excellent, thick, and absorbent after a bit!
Size: 16.9 Fl Oz (Pack of 1)
Wanted the thickest, toughest, best moisturizer I could get for extremely dry, flaky, and all-around lousy skin. This is it. It's thick. Doesn't absorb immediately; you may have to work a little. Can leave a little odd (even slightly sticky) texture on your hands, but only for a very brief period. No visible signs except making your skin look better. The results are excellent. Vastly prefer it over HylatopicPlus, which is a prescription lotion. My mother tried it and bought her own! Also doesn't have lanolin like the original. FYI, apparently the USA version does *not* have Shea (which is a nut) but some international versions do. I'm in the USA and both mine were Shea-free. The listing here shows both ingredient lists in the pictures. If this is a factor for you, make sure to check. All told, will be using this as my main moisturizer.

Excellent For Severe Dryness!
Size: 16.9 Fl Oz (Pack of 1)
If you have severely DRY skin, get this! You will notice instant relief and smoothness. I have tried ALOT of different Over The Counter skin creams, and this is the most effective for treating severe dryness. Even if your skin is very irritated, there is no stinging or pain. Easy to apply, and it stays moist for a long time. It is not sticky, nor does it have a strong odor. Reasonably priced, too!
