Use acid equivalent to compare products, as 'active ingredient' can cloud the issue when comparing different formulations. 'Acid Equivalent' is the very fine print at the bottom of the ingredients table on an herbicide label.

The recommended rates are glyphosate at 3 pounds per acre plus triclopyr at 2 pounds per acre, on an acid equivalent basis. The combination of the herbicides glyphosate and triclopyr satisfies the objectives for an herbicide mixture, providing a wide control spectrum and timing window, minimal non-target impacts, and the ingredients are readily obtained and easy to use. Is the mixture economical on a per-acre basis, and are the ingredients readily available in useful container sizes?įoliar spot treatment with a backpack sprayer is a highly effective means to manage invasive plant species. For example, laboratory investigations have demonstrated negative effects of surfactants to arthropods through surface exposure and ingestion, and some surfactants have demonstrated acute toxicity to tadpoles at use rates (as opposed to high-dose toxicology investigations).Ī final consideration is cost and availability. However, a formulated herbicide product is a complex mixture of many ingredients, and sometimes the inert (non-herbicide) ingredients can impact non-targets. Herbicide active ingredients are in general only active against plants at labeled use rates. Herbicides with significant soil activity may cause unintended effects on non-target plants through root absorption, or prevent revegetation of treated areas after treatment. Herbicides with restrictions for use near water, or limited site-use labeling limit utility.Īnother consideration is potential non-target impact, whether the non-targets are plants or other organisms. An ideal mix for invasive species management would effectively control all targets you encounter so that you don't have to make multiple passes through an area.Īn effective mix also provides flexibility through a wide application timing window, as well as location within the landscape. Herbicide Mix ObjectivesĪn effective herbicide mixture increases the species control spectrum and utility over the individual ingredients used alone. This article will provide details showing this mixture is effective, versatile, and poses minimal risk to non-target organisms. However, a mixture of the herbicides glyphosate and triclopyr can address most invasive plant species issues, particularly if you are foliar spot-treating target weeds (Figure 1). OK, a single herbicide mix will not address every weed management situation.
