Older, larger trees have thicker bark that impedes herbicide movement. From these areas, tree-of-heaven has spread and become a common invasive plant in urban, agricultural, and forested areas. In some cases a combination of techniques, such as basal bark It features a patented, nonpetroleum-based, plant-derived seed oil solvent that helps reduce environmental impact.

We did not publish that data because the sample size was small. The 1995 oil treatment timed to avoid the new growth gave moderate adelgid control . Recently, Kaleb Baker of NIU is doing a similar study but in the fall, winter and spring. Bill is probably getting good results because he applies the herbicide thickly, whereas other people are not getting decent control because the herbicide is applied thinly. Mix Milestone at 0.5 percent to 5 percent v/v with Garlon 4 Ultra in a commercially available basal diluent. Kaleb Baker getting good results applying triclopyr ester on the basal bark of Asian Honeysuckles makes me wonder what people in my area have been doing wrong.

Both cut stump treatments were equally effective on the larger two size classes of shrubs, but efficacy declined on smaller shrubs due to operational difficulties of locating all shrubs in a treatment unit. See the product label for details. We marked each treated shrub with a ribbon that was color-coded to the treatment type and application style. Of course, an emulsion probably would not work when the temperature is below freezing. Basal Application.

These non-native plants thrive in full sunlight, but can tolerate moderate shade, and are therefore aggressive invaders … An oil formulated herbicide solution containing 6% triclopyr (Garlon 4, Pathfinder) as active ingredient is sprayed evenly around the stem to a height of about 12-15 inches above the ground. Streamline Basal Bark Treatment - To control or suppress susceptible woody plants, mix 20 to 30 gallons of this product with … As a general observation, there were still dead zones from the overspray of the oil-water emulsions for both the fall and spring treatments, although it seemed to be a little more diffuse than with the straight oil basal bark treatments. Basal bark treatment is a selective method of controlling woody vegetation by spraying chemicals that are labeled by the manufacturer for the specific use on the stem (bark) of the targeted plant species. It just takes close to one full year for the bigger ones to die. The honeysuckles that appear to have “shaken off” the herbicide application were likely sprayed with mostly just water. Basal bark treatment is a woody invasive plant control method that involves spraying herbicide or herbicide mixture carried in oil onto the stems bases of target plants. Keep on treating this fall using basal bark applications, Five benefits of dormant-season brush control, Study aimed at halting the spread of leafy spurge, Infuse selectivity for savings, less scrutiny & enhanced biodiversity, As a selective treatment where other species are to be left untreated, As a follow-up to mechanical clearings or reclamation projects, For treating areas of high public visibility or areas that are inaccessible to heavy equipment, On sites that require routine — but not intensive — maintenance, Where a low profile is required to maintain desirable vegetation, On sites not able to be treated during the foliar season.
