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

Well worth it. Works as intended

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

This worked great. Highly recommend it. Zero bindweed or dandelions so far. Please note...... you have to water your lawn before using it so the seeds of weeds germinate! I watered the lawn and the rock borders 3x in one day before I used this. Also....add some food dye to the solution in case you're missing overlapping hand spraying. My lawn was brown and added several drops of green food dye to help.

First time using this and it is amazing. Highly recommend. Amazing product.

Tried for the first time this spring up here on Long Island New York. Sprayed the front yard in the begining of March. No weeds yet. Not one dandelion, clover or anua poa. It is now June 1st and I am going to do a light application before any crabgrass wants to poke thru. I will then reapply in early November after I oversees. I don't know if this stunts grass growth or not but I didn't apply any in the back and it seems that my front yard, where I applied this stuff, doesn't grow as fast as my back yard.

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.

Very effective when used as a pre-emergent weed treatment. I apply in late January or February before a rain or snow event. I use this all over my decomposed granite back yard, You can apply several days before rain or snow arrives. The rain or snow melts into over the applied surface and helps the Prodiamine to penetrate several inches into the soil below. I live in Nevada where lots of sun and wind produces weeds that grow quickly from April through October. I used to spend hours digging weeds out of the decomposed granite. Roots would often grow 6" deep which made extraction difficult. The 5-pound powdered concentrate will probably last me 20 years.
