<p class="MsoNormal">Hi MAIPC members,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Does anyone use oil-based triclopyr rather than water-based on ailanthus as a stump-cut treatment? We’re looking to remove a large number of ailanthus in DC before the spotted lanternflies arrive in force, and the vendor is proposing to
do a stump-cut treatment with triclopyr. I want to recommend that they use Garlon-4 or equivalent rather than Garlon-3a or equivalent, because the herbicide can be applied to both the sapwood on the stump and the bark on base of the stump. But I also saw
a study from Italy that indicated that glyphosate is better for stump-cut treatment of ailanthus.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The trees must be removed at the time of treatment, so using hack-and-squirt or typical basal bark treatments won’t fly. Any advice from the membership?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thanks,<o:p></o:p></p>
