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.

great purchase
Size: 48" X 10', Color: Grey, Number of Items: 1
I bought this AmazingSpark soundproof room divider panel because I work from home and needed a way to separate my workspace from the rest of the room — and honestly, it’s been such a great solution. The 48" x 10' size is big enough to create a true sense of separation, and the foldable design makes it easy to move around or tuck away when I’m done working. I use it mostly in my home office, but I’ve also tried it in our guest room when I needed a little quiet space to focus, and it worked perfectly. The first thing I noticed was how sturdy and well-made it feels. The fabric panels are thick and tightly stretched, and the frame has a solid feel without being too heavy to move. I really like that it comes with straps and a stand, so it stays put even if you have pets or kids running around. The neutral grey color blends nicely into any space — it looks sleek and professional but still warm enough to fit in a home environment. As for soundproofing, it’s not total silence (no panel really is), but it makes a big difference. It does a great job of dampening echo and blocking background noise, especially when I’m on calls or recording audio. It’s been a huge improvement compared to the open room I had before. I even noticed my space feels cozier and less “echoey” during Zoom meetings. Setting it up was straightforward — it took me about 15 minutes by myself. The panels fold like an accordion, so you can easily adjust how much space you want to block off, and it’s easy to collapse and store when you don’t need it. The handles and lightweight construction make moving it from one room to another surprisingly easy for its size. One little thing to note: if you have hardwood floors, it helps to put something soft underneath the stand to prevent sliding when you bump it. It’s not a dealbreaker, but it made a small difference for me. Other than that, it’s super stable and does exactly what I needed. What I really appreciate is that it’s multi-functional — I use it as a sound barrier for work, but we’ve also pulled it out to create a bit of privacy when guests stay over or when I just want to section off a reading nook. It instantly changes the feel of a space. Overall, this divider has been practical, stylish, and surprisingly effective. It gives me more control over noise and privacy, looks great, and folds up easily when not in use. If you work or study from home and need a quick way to carve out a quiet corner, this thing is absolutely worth it.

Light enough for one person to move, sturdy and so versatile
Size: 48" X 10', Color: Grey, Number of Items: 1
The AmazingSpark Soundproof room divider panel has been a fantastic addition to my classroom. Its sound-absorbing design noticeably reduces noise, which makes small group instruction, testing sessions, and independent work time much more manageable. The panel is lightweight yet sturdy. The included stand and straps keep it securely in place. I appreciate how easily it folds - setup and storage take only a minute, which is perfect for transitioning from one activity to another. The grey color looks clean and professional, and I can use push-pins to hang displays on the board. The divider delivers exactly what teachers need: privacy, noise reduction, flexibility, and durability. The noise reduction feature has been beneficial in my classroom when students are recording projects. While the class is working quietly on other activities, a small group can move to the opposite side of the panel and record their audio files. When we listened to the files, we could not hear any background noises, with the exception of the noises they wanted in their recording. This panel is made to last, and I would recommend it for anyone who is looking for an acoustic panel that is flexible. The panel is extremely versatile, and because of that, I think it is a good value for the money. Noise reduction, privacy screen, or to section off one area from the rest of the room are just a few of the uses of this product.

Easy To Use
Size: 48" X 6', Color: Grey, Number of Items: 1
Panel measures 48x6 and is super easy to install/put up. It's made of a soft thick material that has an accordion shape style/design and stands up nicely wherever you put it. Quality of the material is good- it's light, easy to use and can be moved with ease. It's also sturdy for being soft and does the job if you're looking for a room divider if this size. The height is shorter than the standard style divider but serves the purpose. Says it has 'soundproof properties'- may absorb some noise but you can still hear. I'd recommend it if you're looking for this style of partition wall for privacy. Noise factor not sure but the material it's made of looks like it should absorb some noise. Moreso recommended for the function, separation and quality.

A Game-Changer for Focus and Privacy!
Size: 48" X 6', Color: Grey, Number of Items: 1
I was excited to try out this Soundproof Room Divider Panel, and it has genuinely exceeded my expectations! I set up the 48" x 6' grey panel in my home office, which is often subject to noise from the rest of the house, and the difference in my ability to concentrate is remarkable. The combination of the acoustic foam and felt really does a fantastic job of dampening ambient sounds, making it a true soundproofing and privacy solution. Assembly was a breeze; the included curved support stands attach quickly, and the panel is stable yet lightweight, making it super easy to move around and reposition as needed. The fact that it folds down to a compact 48" x 15" is a huge bonus for storage, but I honestly haven't needed to put it away because it's so useful! I love the multi-functional nature of this partition. Beyond just reducing noise, the felt surface acts as an excellent display board, I've already started using thumbtacks to pin up project notes and schedules. It’s given me a dedicated, quiet, and visually organized workspace. The flexibility of the foldable design means I can position it in various shapes to customize the privacy zone. For anyone who needs to carve out a peaceful space for studying, working, or even just relaxing in a shared environment, this is an excellent, high-quality solution. The grey color is sleek and unobtrusive, blending seamlessly into my decor. I highly recommend this portable acoustic divider—it's been a great addition to my home.

Not sure about the price, but solid!
Size: 48" X 10', Color: Grey, Number of Items: 1
This soundproof divider worked surprisingly well for creating a quieter workspace. It doesn’t block all noise, but it definitely reduces echoes and softens background sounds. The panel is sturdy, easy to fold, and the stand keeps it stable. Great for extra privacy or separating areas without drilling anything.
