The invention features compositions and methods that are useful for controlling or inhibiting growth and/or survival of undesirable plants (e.g., weeds).
The present invention is based, at least in part, on the discovery that herbicidal compositions comprising fatty and organic acids, an essential oil or phenolic extract thereof (e.g., eugenol, thymol, carvacrol), and a surfactant are surprisingly effective in reducing the growth and/or survival of undesirable plants. In particular, herbicidal compositions disclosed herein not only provide rapid onset control of undesirable plants, but also provide long-term suppression of reemergence of undesirable plant growth. Without intending to be bound by theory, the particular combination of an essential oil or phenolic extract thereof (e.g., eugenol, thymol, carvacrol) and a surfactant is believed to significantly increase the porosity of the surface of the plant, thereby rendering the herbicidal compositions disclosed herein surprisingly effective.
The invention provides compositions used for controlling or inhibiting the growth and/or survival of an undesirable plant (e.g., weed). In embodiments, the compositions comprise a fatty acid (e.g., caprylic (octanoic) acid, pelargonic (nonanoic) acid, ammonium nonanoate, capric (decanoic) acid, undecylic (undecanoic) acid, and/or lauric (dodecanoic) acid), an organic acid (e.g., vinegar, acetic acid), an essential oil or phenolic extract thereof (e.g., eugenol, thymol, carvacrol), and a surfactant.

Multiple undesirable weeds were hand sprayed with a composition (TBH-003) comprising caprylic acid, vinegar, eugenol, and a surfactant using a hand sprayer (
Multiple individual broadleaf and grass species were hand sprayed with a test composition containing caprylic acid, vinegar, eugenol, and a surfactant (TBH-003) using a hand sprayer. Both pre- and post-application photographs were taken for each individual plant, where the post-application photographs were taken at around 30 minutes (
A study was run at a commercial organic blueberry field. Weeds, such as morning glory and Amaranthus, were predominant in the field, whereas wild mustard and some grasses were present in smaller numbers in test plots.
Furrows between the blueberry plantation infested with weeds were treated with 3 different concentrations of an herbicidal composition containing caprylic acid, vinegar, eugenol, and a surfactant (TBH-003 half rate, TBH-003 1×/Full rate, TBH-003 2×/Double rate). Each test plot measured 6 by 35 feet. A spray volume of 30 gallons per acre was used to spray on the ground with 2.5 ft wide boom and hollow cone nozzles. Observations were taken at 1, 7, and 14 days after application. No phytotoxicity of blueberry plants was detected during this study (Table 1).
TBH-003 containing caprylic acid, vinegar, eugenol, and a surfactant at all concentration rates tested controlled the growth of morning glory (Ipomea sp.) weeds (
Untreated test plots showed increases in morning glory weed population, with new weeds emerging on a regular basis during the course of the study. In comparison, half rate treatment with TBH-003 offered moderate control of emerged morning glory after 1 and 7 days, full rate treatment offered significant treatment of morning glory after 1 and 7 days, and double rate treatment offered significant control as burndown herbicide up to 14 days (Table 2 and
TBH-003 at each concentration rate was able to control the growth of amaranth (Amaranthus sp.) weeds (
TBH-003 at each concentration rate controlled the growth of mustard (Brassica kaber) weeds (

Plots infested with weeds including malva and dandelion were treated with 2 different formulations of an herbicide (TBH-003 High Cap and TBH-003 2×/Double rate) containing caprylic acid, vinegar, eugenol, and a surfactant. Test plots were also sprayed with commercially available herbicides (Suppress® and AXXE®) for comparison data. Each plot measured 5.5 by 25 feet. A spray volume of 40 gallons per acre was used to spray on the ground with 3 ft wide boom and hollow cone nozzles. Observations were taken at 1, 7 and 14 days after application.
Each formulation of TBH-003 showed superior results as compared with the commercially available herbicides in controlling dandelion weed populations (
Each formulation of TBH-003 showed superior results as compared with the commercially available herbicides in controlling malva weed populations (
Each formulation of TBH-003 was able to provide significant control of minor weed populations (

The following insect species were selected for testing: (i) Adult Myzus persicae (i.e., Peach potato aphid); (ii) Adult Frankliniella occidentalis (i.e., Western flower thrip); and (iii) Adult Tenebrio molitor (i.e., Mealworm beetle).
TBH-003 1×/Full Rate was diluted as according to the table below to produce a single spray run.
10 adult aphids, thrips, or beetles were plated on each 9 cm Petri dish. 3 replicate Petri dishes were prepared for each species, for each spray run, for a total of 9 Petri dishes/spray run. A 15 mL dilution (according to Table 13) of TBH-003 1×/Full rate was then applied to each of the 9 dishes in the spray run, for a total spray are of 0.5 m2. The spray volume per spray run was therefore 30 mL/m2 or 300 L/ha.
