Is there even anything granular-spreadable, WDG or pre mixed liquid that ONLY prevents weeds and doesn't have post emergent or fertilizer included, both of which are likely illegal to use in late-winter/early spring before weeds are even active and the lawn isn't even eating.

I know preen isn't made for use in lawns but I just found this but haven't looked into active ingredients etc:

Preen 15 lbs. Lawn Crabgrass Control, Covers 5,000 sq. ft. 2464064 - The Home Depot

Protect your yard or outdoor area by using this Preen Lawn Crabgrass Control.

I use prodiamine WDG but want something I can suggest to others for DIY and I doubt they'd want to buy a whole container or prodiamine, tank sprayer, mix it properly and spray it. Same with Tenacity but also that has post emergent you shouldn't use before weeds are actively growing but if seeding in Spring/Fall and there's existing weeds that's the go-to product.

Usually a homeowner will do it later like mid spring, and there are plenty main-brand bagged granular etc that are both 'weed killer and preventer, season long protection' but I'd also suggest for post emergent something liquid even just something simple premixed that attaches to a hose will likely work better than granular for post emergent.

If seeding, granular 'scotts starter with weed preventer' (only prevents about 6 weeks but does allow grass seed to grow) isn't a bad choice if there's no existing weeds then meso/tenacity.

I can get Award Dimension .10% and it’s granular for spreading from our local co-op. I used to spray Prodiamine for my home but I got sick of trying to find time where I was available, it wasn’t windy as heck and rain was in near forecast.

Dimension is dithiopyr

The preen kills emerged crabgrass so it‘s dithiopyr.

Dimension is dithiopyr

Yes it is, but he made a comment about homeowners not wanting to get wettable stuff and a sprayer and doing all that.

Dithiopyr is granular easily spread and available to homeowners at least around here.. Just thought I’d mention it

 

[Rick1111]

Just going by the thread title. I use Dithiopyr all the time in granular usually a 13-0-05 plus Dimension and it does ok. Not near as good as others I use but I use it exclusively on fescue areas here which are few and far between.

 

[roody2333]

thanks for the replies, last time I asked this like 7 years ago I couldn't find Lesco Dimension (dithiopyr) in the north east for some reason, nor shipped to store or home delivery via home depot site/lowes which I want for suggesting to others who don't want to break out the measuring spoons and sift through PDFs etc about using prodiamine.
Now I do see they have Dimension on home depot site and if not in stock locally it'll arrive free shipping in only a couple days. That's a good first app in spring I can suggest will feed the lawn. Personally I use mostly organic nitrogen but some urea is good to boost the lawn in early spring to beat the weeds (because pre and post emergents are not %100, hence All major chain/regional lawn treatment companies, scotts, true green etc packages have pre and post emergents scheduled AND often overseeding in Fall because cool season grasses in the north east in many full sun areas even w sprinklers can be problematic and thins over time if not perfect conditions and routine.
Dimension is quite pricey though at $80 a bag covers 13k sq ft an average lawn might only get 2 apps outa that bag plus it shouldn't be used past the first Spring app or it'll hinder any possible overseeding in Sept/Oct as it's pre-gauged to prevent 4 months, so it'd need to be stored away and use the rest next spring. Also it's wrong and illegal to use the nitrogen in it in late winter like a normal prodimaine app while the lawn isn't even active yet, or to use in Fall for things like hairy bittercress, chickweed, and purple deadnettle.

But I did find vigoro now make a 0-0-0 pre emergent $25 for 5k sq ft w free fast delivery.

Vigoro Crabgrass & Weed Preventer, 17 lbs., 5,000 sq. ft. 22524-1 - The Home Depot

Prevent grass seed and other weeds for few months by using this Crabgrass Preventer from VIGORO. Suggested to apply on established lawns.

www.homedepot.com

It's also dithiopyr. Prodiamine is way way better than dithiopyr afaik, I did read prodiamine holds to soil better and I've had amazing results spraying it in things like worn out paver joints in a sloped driveways where I expected it to wash out and they were too cheap to have it properly resanded, and sealed, but 1 app in spring and there's no weeds the whole season. dithiopyr will kill young crabgrass unlike prodiamine but if you put dimension that late when Crabgrass pops up then it'd hinder any overseeding in Sept/Oct, and drive xlr8 or any attach-to hose easierier crabgrass killer spot spraying would be a better option anyway.


And, there's Spectracide granular which is a broadleaf post emergent, but also has 4-5 months preventer also as dithiopyr.

10.8 lbs. Weed Stop For Lawns Plus Crabgrass Preventer Granules, Up To 5 Months Of Control

But, if there's not many weeds I don't suggest blanket app'ing the whole lawn with this just for the sake of weed prevention, better to just spot spray broadleaf with something like ortho liquid, plus liquid works way better as a post emergent than these granular types which often suggest wet the lawn first so it sticks to the leaves mode of action.

so basically, a good suggestion if they don't want to use prodiamine and my organic program, is suggest the vigoro 0-0-0 granular, and if overseeded in Spring then use the scotts starter 'with haltz' which only prevents for about 6 weeks though and then I guess just do a lighter app of the vigoro 0-0-0 in case they want to overseed in Sept/Oct again which is always a better option that Spring seeding but don't want the dithiopyr still in the soil by then if use the vigioro 0-0-0 sometime around mid june is better to follow up with a lower 3-month dose of prodiamine that'll fade out by mid sept so grass seed can grow.
Again, most homeowners don't want to special order prodiamine, learn the pdf etc and tank sprayer, but it's by far the best esp for beds or pavers etc too since all the other products aren't meant for that and they'd have to use bottles of Preen which probably gets pricey and not as effective as prodiamine.
It's good to offer an emailed/printed follow-up guide after seeding random peoples' lawns that aren't your regular customers and include these options of vigoro, preen etc in there though instead of talking about the lawn for accumulative hours, weeks, months when it's all added up amongst the seedings and expect them to remember everything, or to just basically be like 'ok the aeration, slice seeding, and overseeding was $650 total thanks see ya' and then their lawn declines the following years as cool season grasses in the north east often do, cool season lawns suck, I wish I could spray all that shjt dead and replace it with zoysia does amazing in full sun areas in north east and once it establishes you basically never have to worry about it.

Seems to me I remember for crabgrass control...Scotts uses their Halts product--which is pendimethalin. That is their pre-emergent crabgrass control.
Maybe they own the factory.
Here is the info on active ingredient...

My price on a 14-7-7 (memory it may not be exact but close) plus dimension is $35 plus tax for 50#. But that’s through my wholesale account. Again going off memory I believe it’s about 3.5# per k max rate for a split app so yeah about 13k sq ft sounds about right.

That is crazy and wrong on a couple levels. First, that appears to be a stock blend…why does it have phosphorus in it? Second, I get my products custom blended with amendments with 90% slow release for under $30 for a 50lb bag. Fortunately we don’t pay sales tax.

Trugreen owns the factory in India that supplies them with pendemethilum, that’s why it’s their main pre. .

I cut one of their lawns today and it is crabgrass city.

I took over one in my neighborhood, every noxious broadleaf weed in the state. They had supposedly been treating it since Feb.

Hit it with Celsius xtra and msm turf. Much improved after 3 weeks.

What is surprising is that they can do a good job. Some of my best lawns are done by them. Most, though, not so much.

Why should it not have phosphorus in it? It is an element plants and grass actually need. I know the whole “runoff” story so if it is that don’t bother. But if you have another reason I’m all ears I like to learn. But the runoff is BS and has been disproven ad nauseum.

 

[Rick1111]

Secondly 90% slow release? Holy sheet. Do they ever green up? Seriously asking. I went from 50% ECU to 30% because it makes my lawns look that much better BUT I am south in Memphis. The 30% ECU has done me so much better than the 50% for keeping my lawns green it’s not even a question. But I get that different areas different mixes work better. Price wise wasn’t that much different.

^Applying phosphorus is prohibited, but there are some exceptions. Fertilizers containing phosphorus can be applied under certain conditions, such as when a soil test indicates a need or when repairing or establishing a lawn.
At least 11 states ban phosphorus fertilizer use or sale: Illinois, Maine, Maryland, Michigan, Minnesota, New Jersey, New York, Vermont, Virginia, Washington, and Wisconsin
In 2011, we announced we would completely remove phosphorus from our lawn maintenance fertilizers, including Scotts® Turf Builder®, the best-selling lawn fertilizer in the United States.

Seems you're in Tennessee w/ no restriction.
FYI every time I tested a soil in new jersey where it hadn't had Phosphorus applied recently it read zero and is allowed. I can sorta rely on milorganite's 6-4-0 if applied often enough. In jersey we have cheaper oceangro 5-5-0 basically identital to milorganite (from Milwaukee). Other than starter fertilizer's high phosphorus level, idk of an economical way to add clean/organic phosphorus:

Now it's too much nitrogen causing problems. They should make zoysia more of a thing for full sun cool season lawn areas, it basically needs nothing once it establishes and stays thick and weed free.

 

[Rick1111]

That is very interesting. If we aren’t dropping 1# per k of nitrogen your lawn is going to be the lightest green and weakest from a competitive standpoint on the block. I’ve upped my nitrogen over the years just to compete with TG. They drop N constantly. They don’t do much weed killing imo they hide it with N as much as they can. They are the largest in our area.
