Definitions

  • a kit comprising at least one herbicide and a pyrocarbonate, in which the pyrocarbonate has the general formula Ri- 0-CO-0-CO-0-R 2 , wherein Ri and/or R 2 is an alkyl group, and, when combined, the pyrocarbonate enhances the efficacy of the herbicide.
  • the term "herbicide” as used herein (and as defined by the US Environmental Protection Agency; EPA) refers to any substance or mixture of substances intended for preventing, destroying, repelling, suppressing or mitigating any plant.
  • plant encompasses both vascular and non-vascular plants and therefore also includes bryophytes.
  • the pyrocarbonate may accelerate said herbicidal effect of the herbicide, or may increase the strength, effect or action of the herbicide.
  • the pyrocarbonate in the composition may cause greater than 1%, 2%, 3%, 4%, 5%, 6%, 7%, 8%, 9%, 10%, 11%, 12%, 13%, 14%, 15%, 16%, 17%, 18%, 19%, 20%, 21%, 22%, 23%, 24%, 25%, 26%, 27%, 28%, 29%, 30%, 31%, 32%, 33%, 34%, 35%, 36%, 37%, 39%, 40%, 41%, 42%, 43%, 44%, 45%, 46%, 47%, 48%, 49%, 50%, 51%, 52%, 53%, 54%, 55%, 56%, 57%, 58%, 59%, 60%, 61%, 62%, 63%, 64%, 65%, 66%, 67%, 68%, 69%, 71%, 72%, 73%, 7
  • One or more surfactant adjuvants may be present in the composition to facilitate or enhance the emulsifying, dispersing, spreading, sticking or wetting properties of the composition.
  • Surfactants reduce surface tension in the spray droplets of the composition, when the composition is applied to the plant, which aids the composition to spread out and cover the target plant with a thin film, leading to more effective or quicker absorption of the composition into the plant.
  • Surfactants may also affect the absorption of the composition when sprayed on stems or leaves of a plant, by changing the viscosity and crystalline structure of waxes on leaf and stem surfaces, so that they are more easily penetrated by the pyrocarbonate of the composition.
  • paraquat The key characteristics that distinguish paraquat from other agents used in plant protection products are: that it kills a wide range of annual grasses and broad-leaved weeds and the tips of established perennial weeds; it is very fast-acting; it is rain-fast within minutes of application; and it is partially inactivated upon contact with soil.
  • Gramoxone-200 comprises paraquat (at 200 g/L) and a wetting agent, and it rapidly kills plant tissue on contact.
  • Pure paraquat is highly toxic to mammals, including humans, potentially leading to acute respiratory distress syndrome (ARDS). Ingesting paraquat causes symptoms such as liver, lung, heart, and kidney failure within several days to several weeks that can lead to death up to 30 days after ingestion. Chronic exposure can lead to lung damage, kidney failure, heart failure, and oesophageal strictures.
  • l-Methyl-4-(l-methylethenyl)-cyclohexene is a colourless liquid hydrocarbon classified as a cyclic terpene.
  • the more common d-isomer possesses a strong smell of oranges. It is used in chemical synthesis as a precursor to carvone and as a renewables-based solvent in cleaning products, and as an organic herbicide. Its mode of action relies on its detergent properties which destroy the waxy cuticle of the plant surface and lead to desiccation over several days. Because limonene is a natural extract, it is accepted for organic use.
