Results from a successful "Hack and Squirt" treatment on an invasive privet patch

- If you are familiar with non-native invasive privet (Ligustrum sp.) then you know just how frustrating dealing with an advanced infestation can be! These woody shrubs can grow into impenetrable thickets, that are really more like a wall than a patch. The work can seem daunting. But there's hope! Tunnel through a recently treated privet patch with EcoForester's Forestry Associate and Invasive Species Control Crew Lead, Mary Vann Johnston, as she assesses the results of a "hack and squirt" application. You'll see that this treatment method takes relatively little herbicide and some simple swings of a hatchet to achieve the desired outcome!

it is taking over here in ohio valley. went to Lowes in Wheeling West Viirginia and lo and behold they are selling privet.
Thank you SOOOOO much! I have a lot of privet and have been breaking my back pulling them out, the really large ones, I cut to about 3 feet, and strip the stumps every year so they don't bloom and make seeds, but it's just a temporary solution. It's going to be "Hack and Squirt" for me from now on
Catherine, Glad to hear that you are controlling the privet on your land and that the video was helpful! When the privet is still young (maybe up to 0.5 in at the base) pulling it right after a good rain is pretty effective a well; but you may have tried that already. Good luck with the rest of your privet and let us know how the hack and squirt works for you!
Thank You
Is it okay to hack and squirt in June with triclopyr? Targeting privet, Bradford pear and sweet gum. Looks like you had awesome results! Just curious is June is too early with sap flow potentially still going.
Is there a general rule to follow for application when rain is in the forecast to retain effectiveness of the herbicide?
What I have always followed (and what has worked for me) is that as long as it has penetrated into the wood before it rains it should not loose effectiveness. With foliar spray it has to dry, so depending on the weather, 15min to 1hr.
great video. How long does it take after the hack & squirt to kill the plant and does it kill the roots as well? I have a Chinese privet thicket I want to get rid of on my property. I have a forestry mulcher guy coming later this week but thinking that may just result in tons of sprouts from the roots next spring. If I hack and squirt will it kill the roots if we forestry mulch it a week later?
What herbicide was used in your video, we have the privets all over the farm. Want to get rid of them
Would cut and daub work as well on these large privet plants? Cross bow has 2 herbicides in it, would it work as well as gammon 3 or 4? Thanks for the video!
Yes, it would. I am not familiar with gammon but we tend to stay away from 2, 4 D (one of the ingredients in crossbow) since it tends to linger in the soil and does not break down as fast as triclopyr of glyphosate.
For a privet bush with multiple leaders can you hack just a few to kill the bush or do you need to hack every leader.
In my experience its always best to get the main stem but I have seen privet bushes die after only doing hack&squirt on some of the leaders but with mixed results. I would suggest just to try it and see what happens. I'm sure it greatly depends on the herbicide, its mixture, and maybe even the vascular structures within the wood that transport the herbicide (eg. The herbicide may only kill the portion of the root system that is directly connected to that branch causing the rest of the root system and branches to survive.)
@@arminweise3768 thanks for your reply. Great video.
I’m just curious about which herbicide you used? Thank you.
Hi Pat, we used a 50% solution of a Triclopyr amine herbicide.
@@ecoforesters6521 Thank you!
What chemical did you use? I may have missed it
I think it was triclopyr. Likely 50% solution using a product containing 40% active ingredient. The off brand Triclopyr 3 (summer) or 4 (winter) from Alligare.
Is that Chinese privet?
