The disclosed compositions may be constituted in a concentrated form, or the composition may be further diluted for application. Herbicidal compositions of the disclosure may be employed to selectively target unwanted vegetation without a systemic mode of action, and may be used to control a wide variety of unwanted plants, e.g., weeds, woody brush, trees, and/or grasses, in a locus that contains or is susceptible to emergence thereof. ## Claims ### Claim 1 An aqueous herbicidal composition, comprising: (i) a medium chain triglyceride (MCT) oil-based soap;
