Definitions

  • the present invention relates to the new use of certain known lauric acid esters to increase the activity of active agrochemicals
  • agrochemical active substances in particular those with a systemic action, must penetrate into the plant so that they can develop their activity uniformly throughout the plant.
  • the uptake into the plant either via the leaves or the root is an imperative
  • the penetration barrier of the cuticle must be overcome by the active ingredients.It is also important that the agrochemical active ingredients penetrate the plant quickly and over as large a surface as possible, otherwise there is a risk that the active components will be washed off by rain
  • additives used in crop protection agents such as surfactants, mineral oils and vegetable oils, require the penetration of agrochemical active ingredients into the plant and can thereby increase the activity of the active ingredients.
  • the additives can increase the wettability, a better distribution of the spray coating on the
