Hi all.
Im sure many here have used Pramitol, and since I havent, I figured why not ask here?
Anyway, what Im wondering is, I know Pramitol can leech a bit in the soil, so about how far away from desirable plants/turf should one spray to keep that to a minimum?
Ive read some on it, but it seems to vary from one foot to five, and no one really has any definite answer, or at least more definitive than a 4' range. Many of these that Ive read are simply reviews on sites like domyownpestcontrol or similar.
I have a large gravel drive and a large stone area that need addressed with Pramitol, just for reference.
Previously, Ive used glyphosate, but I have to spray every 4-6 weeks with it, so I am going with a once and done approach this year, finally.
I realize that Ill still have to spray a bit of glyphosate here and there around the edges, but the less the better.

Being I have been spraying my gravel drive with glysophaye 4-5 times a year I am interested in your thread. Have no idea what Pramitol is - is it a herbicide?

In fact just a couple days ago I mixed up a batch of something new to try which is RM-43 which is a glysophate mixed with a pre emergent.

I don't see anything on the label or elsewhere about it spreading or leeching beyond where it is sprayed. The only thing is water runoff carrying it away before the water can soak it into the soil. It does need to be rained or watered into the soil. But too much rain may wash it somewhere else before soaking in. Personally I would stay at least a foot from the edge the first time around to see how it goes.

If your driveway isn't too big, you can water it in yourself with a hose in a more controlled manner to avoid that. You may also want to avoid spraying it in an area where water naturally runs off.

Pramitol is some serious effective preemergent. But if you're worried about it be too effective, just use something else. Prodiamine or Dimension is normal preemergent for lawns and won't kill anything. Not as effective as Pramitol, but it would be good proof.

The label doesnt mention it, but everyone who sells it, or who uses it says so. This may be related to water runoff, but from the few that went into a bit more detail, it appeared that wasnt the only thing causing it. Thats why I was asking for advice from actual users.
Pramitol isnt only a preemergent, it will also kill non woody plants, sometimes it just takes longer that some would like because they are used to round-up. If it were just a preemergent only, a heavy application of Prodiamine would suffice, as most preemergents effects are cumulative, meaning the more you apply at one time, the longer it will last.

I've used it in the past and don't remember exactly how much spread there was. We've used more granules than spray and it depended on how heavy you went with the application but in any case, I don't remember any spread more than 3' and that's being generous.

Effectively, it's a soil sterilant and nothing grows for a period of time. When we used the granules it was to clear a field of Johnson grass. Other herbicides were not available then- pre Roundup days. Fortunately the whole field wasn't infested so we could dig isolated clumps, burn the plants and hit the area with Pramitol. We were pretty generous with the application on those spots because nobody wanted to repeat the process.

Right, you'd use round up as a post emergent to kill what's already there. I'm not sure how well prodiamine and other lawn preemergent will work on a gravel driveway though. Vehicle traffic will be constantly compromising the preemergent barrier. May need reapplication more often than on a lawn. Whereas Pramitol is a soil sterilizer, and wouldn't be impacted by that. Once and death is done for a year or more. But has a higher risk of ruining things you don't want to ruin.

Tractor supply sells it in my area in 2 1/5 gallon containers and I've used it on gravel driveways in the listed concentration.

It will have issues with run-off, at certain points of my driveway it leached into the surrounding lawn.

For me the issue is that it simply didn't prevent some leafy weeds which had me spot treating more than I thought I should have.

Coal, I use RM43 and love it. The key is patience. Mix it strong, put it down, and wait. Takes two to three weeks to see full results. It works wonders at my place.

It moves with water, and quite a bit, chances are if you think it's leaching it was spray drift. As mentioned above it's a soil sterilizer and honestly doesn't live up to expectations. You can try Esplanade, it binds with the soil and doesn't move as bad but pricey. I do this for a living and have yet to find anything that lasts the season, so I have a magic mix and I spray twice, everything is weather dependent, read the label and you'll laugh, if it's to hot, to cold, to wet or to dry it may not work just about every product says this.

RM43 fyi is Round Up and Imazapyr. The round up is what it is obviously. The Imazapyr is a soil sterilizer like Pramitol but has less long lasting effect. Where Pramitol says a year, Imazapyr is more like 3 or 4 months. It also doesn't seem to have the scary ability to expand.

I was not very impressed with Imazapyr's performance over the last 2 years. So I'm trying Prodiamine instead this year on the rock hill. So far so good, but only been 2 months.

Good to hear - thanks for your input!

I’ll be patient - I am looking forward to not having to spray the straight glyphosate every 2-3 weeks for the season. If I can get it down to every 6 weeks I will be happy.

Used to volunteer as a master gardener on the hort helpdesk. Never heard of this nasty stuff. Sounds awful. Kills everything for a year. Glyphosate works fine. Just gotta be warm enough. Is now. Glyphosate runoff/excess gets absorbed in clay soil. Read the label about use in sandy soil.

I made sure not to do my Pramitol on windy days and to use a low sprayer as not to destroy the neighbors property at my parents house on their stone driveway.

Speaking of spray drift, I was spotting some Alianthus tree soriyts with Triclopyr ester/surfacant last year trying to be extremely careful to do on days with no wind. A short time later my farmer neighbor (who has been farming longer than I've been alive) came over to chat with me on how to lay herbicides. He was concerned about me getting too close to some of his (and my) desired plantings.

RalphVA, Pramitol is available over the counter and is listed for consumer use and does not require a license in most states. That's a pretty good indication that it's limited in the environmental (or other) damage that can be done by use or misuse.

As long as you are spraying your own stuff and the product is not restricted you don't need a license, of everything I spray only one product is restricted. Might consider going to a local ag chemical supplier, chances are it'll be better and half the money. Glyphosate is in short supply and almost doubled in price, wouldn't even use it but nothing better to kill grass. A good driveway mix would be glyphosate/dicamba/2-4D and read label for the mix.
