Hello,
We have several large clones of aspen resprouts on a remnant prairie and an
adjacent old field. Does anyone have experience using Krenite (fosamine) to
control aspen resprouts? Some land managers have told me there can be an impact
to herbaceous vegetation despite the claim that Krenite is a bud inhibitor and
only affects brush. Others have said it works well on brush and has no
detectable impact on the surrounding herbaceous layer. I'd like to be certain
of all potential impacts before foliar spraying over high quality vegetation.

The label says Krenite can be used to treat cut stumps. This would minimize any
collateral damage but is it really effective? Any advice would be appreciated.

Thanks,
Lars Higdon
