Atrazine on Organic Lawn

xploitMay 7, 2009

I have recently started using ogranic products on my lawn (compost, SBM). The lawn has a lot of white clover and Dichondra. A lot of people say that CGM is a better fertilizer than a Herbicide, so I'm not gonna bother spending money on that. Since, this is a Flortam lawn my only option aside from ripping the lawn out is Atrazine.

If my understanding is correct, the compost helps increase biological activity in the soil and the fertilizer like SBM feed the biological organizms which in turn help provide the NPK to the grass. I assume Atrazine will kill the biological organisms and another layer of compost will need to be applied after the atrazine; before I can start using the SBM again. Is this correct?

Atrazine is not an acceptable product for anyone that is organic and its use is banned throughout the European Union because of the environmental harm it does.

Don't forget that atrazine can cause significant damage to trees and other woody ornamentals.

I know of the consequences of atrazine. Unfortunately, I have way too many broad leaf weeds that cannot be hand pulled, and I don't have the funds to rip out sections of Weeds/Turf and re-sod with flortam. I guess I'll just have to try atrazine with the organic fertilizer and see how the results turn out.

Frankly you'll be hard pressed to find anyone here with Atrazine experience. If you ask your question in the Lawns forum you'll get more help.
