Excerpt
Excerpt
"Examples of active ingredients in essential oils are:....pine needle oil and eucalyptus oil. Less suitable, but still effective are ... wintergreen oil, cedar oil... Essential oils which may be used in formulations for use as larvicide and insecticide and which are suitable to human and animal use may be selected from pine pyrethrum, tea tree, thyme and essential oils that come from these families... Also useful are rosemary oil and/or wintergreen oil that can be used with plant essential oils such as thyme oil, eugenol and 2-phenethyl propionate, carvacrol and beta-thujaplicine derived from Thujopsis dolabrata var hondai sawdust." "Thus, the present invention also provides a formulation comprising at least one essential oil which may be chosen from those with antimicrobial and/or fungicidal properties as disclosed herein for use in the control of microorganisms and prevention of root intrusion into irrigation tubings....In one embodiment, these essential oils may be used with mixtures of synthetic herbicides for root control. In another embodiment, essential oils with herbicidal properties used. These essential oils having herbicidal properties or synthetic herbicides may be encapsulated together or in different microcapsules. The essential oils having herbicidal properties are those which comprise a monocyclic, carbocyclic ring structure having six-members and substituted by at least one oxygenated or hydroxyl functional moiety. Examples of plant essential oils encompassed within this definition, include, but are not limited to, members selected from the group consisting of aldehyde C16 (pure), amyl cinnamic aldehyde, amyl salicylate, anisic aldehyde, benzyl alcohol, benzyl acetate, cinnamaldehyde, cinnamic alcohol, alpha-terpineol, carvacrol, carveol, citral, citronellal, citronellol, p-cymene, diethyl phthalate, dimethyl salicylate, dipropylene glycol, eucalyptol (cineole), eugenol, iso-eugenol, galaxolide, geraniol, guaiacol, ionone, d-limonene, menthol, methyl anthranilate, methyl ionone, methyl salicylate, α-phellandrene, pennyroyal oil, perillaldehyde, 1- or 2-phenyl ethyl alcohol, 1- or 2-phenyl ethyl propionate, piperonal, piperonyl acetate, piperonyl alcohol, D-pulegone, terpinen-4-ol, terpinyl acetate, 4-tert butylcyclohexyl acetate, thyme oil, thymol, metabolites of trans-anethole, vanillin, ethyl vanillin, and the like. These essential oils may also be used as carriers for encapsulated essential oils with antimicrobial and fungicidal activity. The essential oils either for antimicrobial or/and fungicidal and/or herbicidal may be encapsulated together in the same microcapsules or made in separate microcapsules and then mixed." "EXAMPLE 15 Example 12 was repeated using an essential oil having both antimicrobial and herbicidal activity, such as pine oil, tea tree oil or eucalyptus oil. Formulations comprising, each one or a combination of these essential oils showed good results in controlling effectively both bacteria and fungal growth in the tubing and orifices of the irrigation systems."
