Anyone know of a good one that is non selective and leaves bare earth?
If so, where can I find it online?
Thanks folks.

If you can find a farmer that you know ask them to sell you some of their Round-up. They get it in bill and it's a little stronger than the store bought stuff. Out will indeed take you down to bare earth.

Gene- It sounds like you want to spray it on green, actively growing vegetation and kill it, correct? If so, search for a post-emergent herbicide, and yes, Round-Up (or any generic glyphosate product) will kill most everything, as long as there's sufficient foliage for the plant to absorb it.

There are a few weeds resistant to glyphosate- you can kill those later as a spot treatment with many "Weed Killer"-labeled products.

A good pre-emergent herbicide (keeps seeds from sprouting in the first place) is walnut sawdust or shavings, mixed into the soil or used as a mulch. CAUTION- DO NOT use walnut sawdust around horses, as prolonged exposure can cause laminitis.

Wikipedia's article on "herbicides" lists a number of the commonly available herbicide active ingredients.

I will mix Roundup (or similar) with the pre emergent. The result I'm looking for is a deterrent to vegetation growth for the next season.
Using on a gravel lane.

Just be aware that Round-up is only good for 30 days on contact. That is unless it rains and dilutes the mixture. It sounds like what you want for this application is a gradual release granular type weed killer/control type product. That is the only thing I can think of that will last until next season. I'm not sure what is available out on the market right now for this type of application. Try talking to the folks at your local farm/feed type store. Another suggestion would be to contact your local agricultural extension agent. They would have knowledge as to what is availble and would be effective in your area.

I tend to use mostly Glyphosate (Round-up was original) because it is seasonal and because I might change my mind and want grass there the next year.
One huge problem with the permanent solutions is that you may think you have done it properly but then a heavy rain comes along and it can leach out to the sides. I know one guy who sprayed his drive and with a heavy rain it leached out as far as 8' out to the side into his yard killing everything for years. Also trees and shrubs near the drive can put out roots under the drive and die from it.
BTW, Roundup is over-priced... Generics like Buccaneer are about 2/3rds less and are every bit as effective. I used it on crop land for years.
For a driveway, products like Roundup Ultra or Buccaneer+ are faster.

Ortho® GroundClear® Vegetation Killer Ready-to-Use

My ex son in law who does lawn care gave me a pre emegent herbicide that mixed with Roundup. The Roundup would kill any existing vegitation and the pre emergent would prevent any seeds from germinating.

I think the product was called Zemcon it was bright orange and when mixed with roundup would paint the area orange while wet so you would know where you sprayed.

Did you all know that the mad scientist have made some plants roundup ready. Which is agi talk for saying it is Roundup resistant. The idea was make corn roundup ready and then spray the whole field with roundup. It would kill everything but the corn. Great idea. Except some of the weeds have become roundup ready.

I was shown a picture field of soybeans covered in roundup ready pig weed. There were perfect rows of no vegitation at all except where the soybean were but if you looked close you saw it wasn't soybean but pigweed. What a mess.

Ortho&#174]

I used it last year with good results.

I can attest to the fact that it does not poison the soil. Growth was slow this spring, but with no reapplication, the green stuff gradually returned and is quite 'healthy' this fall!:eek:

P.S. I used the concentrate and mixed with water and applied with a hand pump sprayer(mucho more cost effective than the ready to use)!
