Thanks Scott, we'll see what Bill sends. If I need more I'll let you know. I am interested in doing an experiment using willow steeped water to root them in to see if that helps with rooting.
This year I sprayed after they sprouted so I used atrazine and 2-4'D mixed with dawn dish detergent. In the past I have used Atrazine and gly pre sprout.
Atrazine is a restricted herbicide but I have a freind with a license who closely monitors all activities :)
Paul Knox used to say Simazine was a close second to atrazine for use in switch. Simazine 4L is only restricted in California so you can get it at keystone pest supply. BUT I would try a few plants to be sure the MG is resistant.
