I bought a quart of Lontrel to kill Poision Ivy in blue rug Juniper. I have a Shurflo sprayer that I am mixing 1/2 oz per gallon. I have applied it twice with no effect at all. I went back to Lesco for advice and they told me it would not work for poision ivy even though they suggested it. I have been reading that it has been used in the past. What am I doing wrong? Any advice?

Thanks,
