<p class="MsoNormal"><span style="font-size:12.0pt">If you want just one herbicide for
<b>cut stump and basal bark</b> then I would recommend you use a use a <b>triclopyr ester</b> product (i.e., Garlon 4 Ultra). Mixed at 20% in a commercially available basal oil and applied as indicated, it is effective on all three species you listed. Large
bush honeysuckle (3 plus inches in diameter) can be a bit challenging to control with basal bark applications, but I have found it to be effective when applied to large honeysuckle stumps. When stump treating be sure to treat the cut surface as well as the
sides of the sup and any exposed roots with this mix. <o:p></o:p></span></p>

<p class="MsoNormal">Hi, Anne. <o:p></o:p></p>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">I use the glyphosate:triclopyr mix (3.0 lbs plus 1.5 lbs, acid basis, per acre, respectively) to good effect. The only species I have observed unsatisfactory injury is common buckthorn (glossy is susceptible). If you use it, be certain
to follow the mixing guidelines:<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">- start with 3/4 of the total water<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">- add the triclopyr, begin agitation<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">- add the glyphosate only after the triclopyr is mixed, and agitate immediately or constantly.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">- I don’t apply the mix at carrier volumes lower than 20 gallons/acre - the two ingredients behave at that concentration, but at higher concentrations (lower carrier volumes) you can start to see precipitate.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">Plan on a follow-up. You can be very selective with a low volume application with a backpack sprayer, but you will not get the canopy penetration you would with a mistblower, so retreatment is pretty much inevitable.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">I would push up the window up to September into October. Exotics do hold foliage comparatively late, but waiting into October runs risk of “early” leaf drop or fall color, and therefore reduced effect. I find rose is often defoliated earlier
than the other species.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">I can’t really comment on the training, as I am only familiar with applicator training in PA, which has two levels, Certified Applicator (pass Core and Category exam(s), work autonomously, can directly supervise non-credentialed applicators)
or Registered Technician (trained by a Certified Applicator in a 13-point curriculum, can work autonomously, cannot supervise others). If you wish them to work autonomously, be prepared for the class to be pretty involved and hands-on. Backpack spraying is
simple in concept, particularly if you can distinguish the species, master the equipment and proper coverage, and deal with the terrain and site conditions. (:<o:p></o:p></p>
