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.)

  • May be tank mixed with other labeled herbicides (see label for details)

Love the "B00" Colors, but the "RX" colors are a totally different boyshort!!!!
Size: 3X-Large, Color: B004
The packs that have a color name starting with "B00" are fantastic! I bought the black and grey ones, and a set of the multi-colored ones, and they are the best boyshorts, ever!!! I attest to this now, after 6 months of everyday wear and wash. This first part of this review is only for boyshorts that have a color name starting with "B00"! Read the end for my review of the ones with a color that starts with "RX". Completely different panty. The B00 colors are sewn impeccably well, and they are a beautiful, quality material that resembles very thick, very soft leg stockings (panty hose). They stretch easily in every direction, so they hug your curves perfectly. These are not cotton! I hate cotton undies. These are nylon, or something synthetically similar. Unlike stockings, I think it would be very difficult to put a snag in the material because of how much thicker the material is than stockings. I actually tried to snag them with my torn finger nail just to see, but the material is very strong, so I could not put a run in them. Even though these are thick and soft, they dry remarkably fast, because of the looser weave of the synthetic material. They do not roll at all at the waist or on the legs, and I am a very curvy girl, so if they were going to roll, they would definitely roll on me. They wash very well. I've machine-washed them all weekly for 6 months now, and also tumble dried them on the low setting, at a laundromat. No issues at all with fading, color-bleed. shrinking, ravels, and no pilling. These are definitely my everyday undies. One really nice feature is that since these are tagless, they sewed a few raised lines of soft stitching in the back, so you'd always know where your rear-end goes. One thing some people may not like, is that there is no separate liner on the crotch. It is pretty much the same material as the rest of the panty, but a bit thicker, with an extra light layer of lighter-colored stitching incorporated into the inside of the fabric, to make it a bit more absorbent. I actually prefer this, because it means they dry faster, and they are less likely to fall apart in the gusset, but some people may prefer the extra liner of fabric that is typical for most undies. These are not binding at all, so not a shaper panty by any means, but they are certainly very comfortable and stay where you put them. I would think these would be fantastic for backpacking (I love backpacking!) for all the features I mentioned. I have micromodal boy shorts by meundies that I used to wear for hiking, but I will definitely wear these instead because of the reduced drying time after washing, or when sweating. The other micromodal bamboo/cotton-like materials just hold too much moisture for hiking. Undies that retain moisture can cause painful chafing, and can even contribute to hypothermia. I love these! I am buying more!! REVIEW UPDATE! Well, I did buy more. I bought the 5-pack of color that starts with "RX", and I was super disappointed! The "RX" ones are NOTHING like the "R00" ones I described above. Look closely at the pictures. Those ones with a different fabric panel on the hip are tight, not nearly as stretchy, roll instantly on my inner thighs, dip in the back, are not nearly as soft, and do not dry quickly. They are a completely different boyshort, and I do not like "RX" model of boyshort at all. I suppose if you had no meat on your thighs and you wanted a shaper-type panty, the "RX" might be exactly what you're looking for, but not for me, for sure.

Full Coverage
Size: Large, Color: B2207sp
They're nice and light, super stretchy, and not too tight around the edges. Im a size 14 and got a large amd They're a smidge tight, but I think if I would get an xl theyd fit perfectly, They're still comfy as is. One stipulation I had is I wanted them to cover my whole butt cheeks, nothing cutsie short cut, not for this. They cover my entire booty cheeks and stay there pretty well. Oh and also no camel toe! Id buy them again and would recommend them to anyone.

Make sure you size up!!
Size: 4X-Large, Color: B004
Allllllmost 5 stars if the sizing was correct. I’ve been on the hunt for a decent fitting pair of women’s boxer briefs. I would say these are more so boyshorts. That being said, I wanted something loose for sleeping in so I got TWO sizes up. I normally go for a 2x and got a 4x and they’re perfect fitting. So, you didn’t get what I was looking for but did end up with some decent fitting undies. So I can’t complain too much. Just not the boxer briefs I was hoping for. Super stretchy and soft. Comfortable for sleeping in.
