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.

  • Apply using a low-pressure sprayer

  • Minimum spray volume: 20 gallons per acre (0.5 gallons per 1,000 sq. ft.)

PLEASE MAKE A BIGGER SIZE, NEVER STOP MAKING THIS ‼️
I purchased this a few months ago back in November 2025 because of all the TikTok hype. It's now June 2026, and even though it's only 50ml, it lasts SO long. A little goes a very long way, and I still haven't finished it yet!! I originally bought this to use after waxing my underarms because I'd always get painful bumps, irritation, itching, and overall discomfort. I'd only apply it at night, and by the next day the bumps and irritation had gone down significantly! Whenever I get bumps, irritation, or discomfort, I use it for about 3 days to a week and it works so fast 😍 I really wish they sold a bigger size because the reviews are not lying💯...this thing works wondersss. It's worth every single dollar. It's also pretty good at targeting ingrown hairs too. Like omg, it's basically a painkiller in a bottle 😂 It has saved the day so many times & I've used this quite a lot, lol.

Charming Roll-On Power
I've had a difficult time with shaving with sensitive skin. I can use multiple different types of razors, lotions and creams. It doesn't always work well for me. So I saw this mentioned on TikTok and I thought I would give it a go. I'm impressed by how good it calms any irritation or itchiness I may have. It applies on cool and and it's easy to use. It carries no scent. It's a small roll-on and lightweight. It's soothing and moisturizing to the irritated skin. Works like a charm. Would recommend!

It does work!!
This is definitely worth the buy. I’ve tried a couple different products to reduce ingrown hairs and bumps after waxing, and this is the only product I’ve used that’s made a difference. In a weeks time I’ve seen major improvement in my skin. As a big girl, I’m constantly battling with ingrown hairs and I was honestly ready to just give up waxing. The ingrowns I had when I started using it are less angry, my skin feels more moisturized and I can see other healing blemishes getting smaller.

Effective
Very good product, not sticky, made my skin feel hydrated, it is very effective and has no scent, the only downside is that while it is good for preventing ingrown hair if used consistently (2x a day on clean skin), it does nothing for pre-existing ingrown hairs.

My new Holy Grail product!
This is INCREDIBLE! Ok, firstly, let me say that I apply it after shaving and razor burn is a distant memory now. It has also taken down the drastic redness and red marks that previous shaving had left my skin w. My skin is smoother and softer now.. including my bikini area. Not to be tmi but, I have a c section scar, it’s nearly impossible to prevent ingrown hairs in that area bc of the scar tissue .. or so I thought! OMG , I’ll never give this stuff up ! It also helps w my back acne and is easy as pie to apply , doesn’t smell weird and absorbs nicely .. bonus points.. it will tame the zits on your bum too .. but wait .. there’s more ! My super pale sensitive skin on my legs has been forever marked w scars from shaving and always has little red marks besides that so I’ve always been insecure about my legs even though they’re long and strong .. dude .. I kid you not, this has been taking the red marks out and no more razor burns.. or bumps plus all of the scars are starting to fade !! This is a HOLY GRAIL PRODUCT! I had literally quit shaving my legs before this and now.. I’m feeling so much better about it & myself and omg thank you for this product! Never ever stop making it !
