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.

ACTUALLY heavy duty
Color: Brown, Size: 9 in - 75 count
These plates are actually better than I expected. I’ve used a lot of disposable plates that claim to be “heavy duty” and then immediately start bending the second you put real food on them, but these feel sturdier than the average cheap paper plate. The 9-inch size is a good everyday size too, big enough for a normal meal without feeling tiny, and I like the natural brown color because it looks a little nicer and less flimsy than plain white party plates. For cookouts, birthdays, quick dinners, or anything where I just do not want extra dishes, these have been really convenient. What I like most is that they feel substantial without being overly thick or bulky. They hold up better than the thin paper plates that get soggy fast, and that matters a lot when there’s anything heavier or messier on them. I also like having a bigger pack on hand because disposable plates are one of those things that disappear faster than you think, especially with kids, parties, or just busy weeks. The compostable part is a nice bonus, but honestly what matters most to me is that they actually do the job and don’t feel like they’re going to fold in half in my hand.

Great Value and Very Durable Plates
Color: Brown, Size: 10 in - 75 count
These plates are a great value for the price considering the quantity and the quality you get. Getting 75 plates at this price point is already a win, but the durability makes them even better. They’re biodegradable, which is a nice bonus, and they’re definitely not flimsy. These plates are stiff and sturdy — I can load them up with a pretty heavy plate of food and they still hold up without bending. They also do really well in the microwave, which makes them even more convenient for everyday use or parties. Overall, a really solid disposable plate option that’s durable, eco-friendly, and a great value.

A bit iffy on these plates
Color: Brown, Size: 9 in - 75 count, Color: Brown, Size: 9 in - 75 count
These plates are ok, but certainly not the best I've found. On the positive side, they are what I'd consider "Lunch Size" an are somewhat sturdy. They'll hold a sandwich and chips with little effort so, as a plate, they do... plate. Where I am a bit hesitant is in their molding an construction. You can see in my photos that there is significant staining/watermarking on the plates from the manufacturing process. This could be simply from the way the wet pulp was extruded and formed, but it honestly gives me a bit of the ick. Not that it's particularly gross, but it does make me wonder how sanitary the plates are or what binders might be leeching into my food. In my last photo, you can see a comparison to a compostable plate that I really like. The finish is cleaner and the mold included an inner ridge which gives the plate more stability - making it less likely to flex under weight. Both are sugar cane fiber plates and my preferred plate is a few dollars more expensive for a comparable pack, but the clean appearance and extra rigidity make it worth the added spend in my opinion. Ranking these 3-stars might lead some to think they're bad - and to be clear, I don't think they are. They're just adequate. If you're looking to save a few bucks on a compostable plate, these WILL get the job done. I would just shy away from using them with wet or acidic foods since they don't boast the highest quality of manufacture.

Strong Eco Friendly Plates But Not Great For Hot Food
Color: Brown, Size: 9 in - 75 count
I picked these up because I wanted something more environmentally friendly than the usual plastic or paper stuff. They are made from bamboo and bagasse, and you get a good amount in the pack for the price. For dry stuff like snacks or sandwiches, they are super sturdy and do not bend at all when you pick them up. However, they do not hold up very well when you put hot or wet food on them. Even though they are supposed to be heavy duty, I noticed they can get a little soft if the food is really steaming. They are still perfect for a quick lunch or a party where you want an easy cleanup, but you might want to double them up if you are serving something heavy and hot. The plates are big, and you get quite a bit, making it a really good value overall.

Heavy duty paper plates
Color: Brown, Size: 10 in - 75 count
These disposable plates are amazing. They're large enough to hold an entire Thanksgiving meal. They're sturdy and strong, and won't buckle even when supporting quite a lot of weight. They don't get soggy even when I deliberately poured water in them. The sides are built up to keep food from falling off the plate. These are everything you'd need in a disposable plate, and they're biodegradable, too! These are ideal for barbeques or outdoor entertaining, or even for everyday use in the kitchen.
