Poison Ivy and Herbicides
Is poison ivy "immune" to herbicides because of the urushiol
oil? I know that roundup works by blocking essential enzymes but I can't
figure out why it won't work well on poison ivy. Even the herbicides
that are specifically for poison ivy don't work that well. My research
is on "why plants die." I can't get the poison ivy to die.

Herbicides DO work on poison ivy. Roundup will not work very well, Garlon
