How to kill Invasive English Ivy Vines

EnglishIvy-ThumbnailLargeDispenser

Check out our newest video How to Kill Invasive English Ivy Vines: 3 Steps.  If you like PowerPoint presentations better, here it is: PowerPoint How to Kill English Ivy Vines.  We will be publishing another set of presentations on killing English ivy groundcover.  For that we recommend a foliar or wipe application. English ivy can be a real problem in many parts of the world.  It can climb tall native trees and eventually even kill native trees.  As a groundcover, it also can out-compete natives.  One thing: English ivy can be controlled in the winter when many native plants are dormant.

Concentrated Weed Killer Applied Precisely – the Best Way to Kill Tough Weeds

At Green Shoots, we sell concentrated weed killer and our foam herbicide dispenser systems help you
apply that weed killer precisely and with low drift.  Concentrated weed killer or herbicide is not just more economical.  It is also more effective.

Read this paper (link) from Bryan Young, currently a professor at Purdue about glyphosate rates.  In it he says: “The most consistent application factor that can increase glyphosate efficacy is lower carrier volumes.”  What does Professor Young mean by this?  He means that by adding less carrier (i.e., water) and increasing the amount of glyphosate herbicide (i.e., increasing the herbicide concentration) in the spray solution, the herbicide is more effective.  Moreover, this is the case even though an application may cover less of the target plant.

Take a look at the photos below and this video to see before and after images of weeds treated with low volume/high concentration applications: Video (link).  As you will see in the foliar applications, very small amounts of herbicide are applied to very small areas of foliage (probably covering less than 10% of the green foliage).  In spite of the small amount of coverage, the weeds were completely killed.

How to Kill Japanese Knotweed Using Foliar Application of Foam Herbicide – Presentation at Upper Midwest Invasive Species Conference

This presentation at the Upper Midwest Invasive Species Conference, 2014, summarized some of our control work on invasive knotweed at Southwood Nature Preserve in

University did some testing this summer comparing our foam herbicide dispenser to traditional spraying techniques.  So far (and these results are very preliminary), the foam herbicide has performed better than the spray even though half as much herbicide was used on the plots where foam was applied.  The full presentation is online at: How to Kill Japanese Knotweed.

As soon as we get data from Washington State University on their testing of the foam system, we will provide a link or other information.

New Website with New Products including the Large Foam Herbicide Dispenser

We launched our new website: Green Shoots.  We have several new products on the website: our Large Foam Herbicide Dispenser; Foaming Agent; and Aquatic herbicide.  If you are a professional or have a large piece of property with invasive weeds, you may be especially interested in our Large Foam Herbicide Dispenser.

We will also be adding a resource center in the near future.  This will give you a link to our videos and other postings.

New Products and Website Changes Coming!

In about two weeks we hope to have our new website up!  We will offer several new products including the Large Foam Herbicide Dispenser.  This product will be especially useful for the professional or non-professional who has a big invasive weed project.

We will also be offering an aquatic herbicide and a foaming agent.  The aquatic herbicide will not have manufacturer-added surfactants.  This will allow the user to add a surfactant of their choosing – for example, our foaming agent which will be a mild, non-ionic surfactant made from plant-based materials that are readily biodegradable.
