Normally the only kind you will find in the big box stores is Scott Halts. Usually cheaper than going with kinds like barricade, dimension, Team 2G, XL 2G.

Those are specialty types. I have to get mine from the local farmers coop, but I'd rather use these as I believe they have a longer residual life in the ground.

Thanks TNJDM. I've had a service in the past and they used "Dimension" and "Barricade" which seemed to be very effective. I'm looking at doing this myself but these products do not seem to be commercially available so I'm looking for a replacement.

EA,

Not sure what part of East TN you are in, but if you do want to go with those, google Tennessee Coop and see if there is one in your area. They seem to be all over. They carry everyone of those I mentioned.

You can get "Barricade" as Prodiamine easily on EBAY or Amazon. 5 lbs of the "real stuff" (65%) will last me years and years on an acre of land. For the person with 5K-10K, it will last a lifetime. It goes for around $80. Don't think you are getting a better deal when you find 50 lbs for $70 -- that is the "already-diluted" stuff at 0.375%. The real stuff is not difficult to work with.

Thanks Andy!

I'm in East TN in Knoxville area.

Do you use one particular preemergent or find a combination works better? The service I had used Barricade (Prodiamine) as the first application in February followed by Dimension for the following months until Summer.

I've found a 5lbs container at doyourownpestcontrol.com for $70 with free shipping. A 5lbs container should last me 10 years on my 1/2 acre lawn. I did a complete renovation back in the fall using the good stuff from The Hogan Co. and currently have no weeds but plan on applying a pre m later this month. Everyone around me does nothing with there lawn so I'm surrounded by every weed imaginable. My lawn had been overtaken by both crab and dallis grass so I'm hoping to prevent that from happening.

At 1lbs per acre the Prodiamine should give 6 months of control. Applying at the end of February should mean I'm covered until September when
I will overseed if needed. Right now my lawn is very thick and weed free. The pre m might not be necessary but with the time and money I spent in the fall I'm not about to take any chances.

eacollie,

You can pick up any pre-emergent you need at you local farmers coop. Barricade, Dimension, XL2G, Team 2G, Gallery. I have got them all. Trust me. its a lot cheaper than doing it on-line as I had done it for years until I visited my local coop.
