Prodiamine 65 Wdg 5lbs Pre-emergent Grass Broadleaf Weeds ( Generic Barricade )

This stuff is awesome and yes higher upfront cost, but long term way cheaper as per application cost is very low.

This is a great option for the spring/later fall pre emergent applications to prevent future weeds. Just make sure you're rotating your active ingredient between seasons. Great product. Best application is to apply this as a sprayed in application and watered in shortly after. Try not to apply this if there is heavy rain forecasted or if you cannot water the product in correctly.

Works great. I apply late September and late March, has GREATLY reduced weeds. Very noticeable

Kept everything out of my yard except Bermuda and St. Augustine grass.

Put down an application in the fall and will again in the spring. Hopefully it does what it says it will.

Seems to do a good job of preventing crabgrass. I found that if you mix it in a 5 gallon bucket and spray with a hose and electric pump, it is quick and easy. This is by far the most economical way to apply pre-emergent, only costs a few dollars per application and the jug of granules will last many years

Prodiamine has been around for a long time and it works very well when used properly. I have a 15,000 sq. ft. lawn and I may not be able to use the entire container before it goes bad. A 15,000 sq. ft. is larger than most average homeowner lawns by far, so most will not be able to use the container before it reaches the end of its shelf life. Lower strength? For my 5,000 sq. ft. front lawn I think it took 0.92 ounces to treat it all this past fall. As concentrated as it is, it is not easy to measure such a small amount without using a digital scale. Unless you're a lawn care nerd like me, most people with digital scales only use them for food, and it's not wise to use a food scale for herbicides unless it is only used for non-food use. Results: I have not put down desirable seed in my 10,000 sq. ft. back lawn yet, but in the 5,000 sq. ft. front lawn of Zoysia I think I have 3-4 weeds that are green while the rest of the lawn is dormant and a golden-tan color. That means either I simply missed a few spots in my application or these may be perennial plants versus annual, which prodiamine stops plants before they emerge, so if it was not an annual, it would not effect the plant so it was not a fault of the product. This stuff worked well, as long as you apply correctly and at the correct times and soil temperatures. Tip: The bacteria in the soil is what breaks down the prodiamine, meaning if you apply this in the middle of summer when it is really hot, the soil bacteria will break this down much faster. Most people say to put this down when the soil is reaching 55 degrees to stop crabgrass, but that is too late in my opinion. If it happens to be raining for several days and you get this down too late, you will have unwanted weeds for months until the heat kills them off. I spray this down between 45 and 50 degrees, and know lawn care professionals that apply this as low as 35-40 degrees, then if there are any weeds popping up they come back with Dithipyr as needed. Tip: Do not apply before core aeration. if you aerate, you're punching holes in your protective barrier and may end up with weeds and not know why. If you need to aerate around the time you apply, do a split application with half before and half after, or if possible, shift when you aerate. My neighbor has a lawn that looks like it was stolen from a golf course, but he still fights with weeds on occasion and I think this may be why. Tip: I could not find anywhere a temperature for fall application. When I ask, I just had people tell me over and over that you apply in the late winter/early spring before the soil temperatures reach 55 degrees, but cool season weeds that start to grow in the fall are not covered by this rule. I did find a few people saying to apply this in the fall before the soil temperatures start reaching 70 degrees, which is what I did this past fall and it did seem to work well for me. This was my first application so I'll just get a sponge and some glyphosate and kill those few weeds and between the thick growth of Zoysia and this pre-emergent, that should manage 99% of my weeds. I will buy again. Although with the amount I have, I'll probably share with my neighbor.

This stuff works well. Haven’t seen a weed in months.
