[MAIPC] Ailanthus and Basalbark Treatment

[gludington at aol.com]

To illustrate the effectiveness of hack and squirt, Jonathan Kays (Principal Agent & Regional Extension Specialist, Natural Resources UMd) showed a group of us in a MD Woodlands Steward class (a couple of years back in May) a large grove of +/-40 foot ailanthus he had treated this way (using Garlon4 (triclopyr) in a oil base) near the Keedysville, MD Extension office the previous fall (October, I think), when nutrient flow was going back down into the root system. The following May, we were looking at completely dead vegetation with no apparent sprouts.  I suggest you contact him for more information: jkays at umd.edu 301 432-2767 Ext(323) | Fax 301 432-4089.


Cheers, and good luck,
Gay Ludington

I recommend hack & squirt, making axe or machete cuts around trunk and using a spray bottle to spray herbicide mix into cuts, now through end of year.  Tree will die with no sprouts and you can cut it down in winter or spring before it gets brittle.

Hi Everyone,
     
 
     
Tree of Heaven is a big problem in Reston. Due to the make-up of our open space, in many areas surrounding recreational facilities and homeowner property, we cannot leave dead looking standing trees for months at a time. Residents complain and it reduces the “curb appeal” that the Association is trying to improve. 
     
 
     
I would like your input on this matter. When applying Triclopyr in a basal bark treatment, how long does the tree need to stay before we can cut it down? (2 months? 6 months?) 
     
 
     
In certain cases, I think we’ll be forced to do a cut stump treatment instead. We typically use glyphosate at 20% on the stump. How problematic is this method with Ailanthus? I know it can be effective in killing the large tree but then we have runners to manage. 
     
 
     
Thanks for sharing your thoughts,
     
Patricia
