Disclosed are compounds having a monoterpenoid and/or phenylpropanoid moiety and methods of their making and use as pesticidal compounds, such as seed treatments.

Disclosed embodiments of the present invention concern an herbicidal combination, such as a premix concentrate or a tank mix, comprising 1% to 10% of a triketone herbicide, such as a benzoylcyclohexane-1,3-dione, and 30% to 50% of a diphenylether herbicide, such as a 2-chloro-4-(trifluoromethyl)phenoxy]-2-nitrobenzoic acid. Certain embodiments comprise, consist of, or consist essentially of, mesotrione and oxyfluorfen. Particular compositions comprise an aqueous composition comprising oxyfluorfen, mesotrione, a surfactant, a freeze/thaw agent, a defoaming agent, a rheology agent, and an antimicrobial agent. A method for using disclosed combinations comprises applying a combination to a locus where undesired vegetation is present or may be present. Yet another embodiment comprises a method for forming a disclosed combination, such as a premix concentrate or a tank mix, comprising, consisting of, or consisting essentially of, (1) a triketone herbicide, such as mesotrione, and (2) a diphenylether herbicide, such as oxyfluorfen.

A method of controlling odor where the odor is generated by sources like decomposing organic matter in landfills or other sources is provided. A wood vinegar-containing solution, adjusted for the source of the odor, can be applied to the source of the odor. A method of improving the rate and completeness of settling of fine clays from oil sands tailings is also provided. Additional disclosure of a method of controlling algae bloom in a body of water is disclosed. The method includes the steps of providing a wood vinegar-containing solution, adjusting the composition of the wood vinegar-containing solution according to the states of both the body of water and the algae, respectively, then applying the wood vinegar-containing solution to the surface of a body of water, and inhibiting growth of the algae responsible for the algae bloom.
