We posted an animated video on YouTube showing how to kill a weed tree using foam herbicide. The video also explains why foam herbicide works better than liquid herbicide for cut stump applications.
Treating a tall weed with herbicide or weed killer can be a challenge – especially if the target weed is near desirable plants. Conventional sprays are difficult to control. Fine droplets are hard to see, so it is difficult to know what you are treating with the herbicide spray. Moreover, the fine droplets in sprays have a tendency to drift. And, when the droplets do land on the target weed, they may bead and roll off the leaf.
This video shows an application to a perennial thistle using the Green Shoots Foam Herbicide System (link to video). Note how precise the herbicide application is – without drift, drip, or off-target spray. Toward the end of the video you can see the results where the weed has dead fifteen days after treatment.
We just finished a video on how to control Canada thistle using the Green Shoots foam herbicide system (link). The video shows how our small foam herbicide dispenser creates a thick foam herbicide that sticks well to leaves and green stems. In the video we use the small foam herbicide dispenser and physically wipe small amounts of foam to the leaves and green stem.
We are using glyphosate herbicide with the wiping technique. The label that accompanies the herbicide you use should explain more about herbicide wiping. Many labels recommend a
33% to 100% solution for use with wiping. However, you can use a less concentrated herbicide solution than that. We are using a 10% concentration in this video.
Background on Canada Thistle – Canada thistle (Cirsium arvense) is an invasive thistle in North America and is identified as a noxious weed in many states. It is an exotic or non-native species brought to North America from Europe (not Canada!) possibly as early as the 1600s. Since that time, Canada thistle has invaded prairies and grasslands, especially in the Midwest, Great Plains, and southern Canada. It out-competes desirable, native species like grasses and wildflowers. In this way, Canada thistle degrades wildlife habitat and reduces ecological diversity.
Canada thistle has rhizomes (underground stems) that grow laterally and up to a depth of about 3.5 feet. New shoots develop from the rhizome and thus a stand of Canada thistle might orginate from one rhizome.
Other common names include: Californian thistle, Canadian thistle, creeping thistle, field thistle, corn thistle, perennial thistle, field thistle. For more information on Canada Thistle, visit the United States Department of Agriculture National Agricultural Library (link).
This blog offers news about Green Shoots. Green Shoots is a company that develops and offers products to control invasive plants.
Invasive plants such as kudzu, Japanese knotweed, buckthorn, and Brazilian pepper tree are devastating native ecosystems. Green Shoots offers a better way to control them.
Our precision herbicide dispensers (patents pending) apply a concentrated herbicide foam under ultra low pressure. The foam herbicide sticks tenaciously and dries more slowly on the targeted weed. This increases absorption of the herbicide into the weed. In addition, our system dramatically reduces drift, overspray, and drippage.
Not only can our products help control invasive species, they can also help reduce harm to desirable plants and the broader environment. Hence, our credo: control invasive species – restore native balance.
