Definitions

  • the invention relates to the field of chemical crop protection, in particular the use of a special compound as a penetration promoter for agrochemical active substances from the group of herbicides and safeners and
  • Plant protection product containing this compound.
  • the compound is tributoxyethyl phosphate (CAS Regno: 78-51-3, hereinafter referred to as TBEP).
  • penetration promoter is understood to mean compounds which promote the uptake of herbicides and safeners, alone or in a mixture, through the cuticle of a plant into the plant, ie accelerate the absorption rate and / or increase the absorbed amount of the active substance into the plant.
  • Substances which increase the penetration of herbicides and / or safeners through the cuticle of the plant are valuable auxiliaries in chemical crop protection.
  • Various classes of substances are already known as penetration enhancers (see for example WO 2005/104844 A).
  • DE 3513889 A1 generally treats penetration promoters as "activators" for biocides and
  • EP 579052 A2 describes compounds from the group of alkyl phosphates, such as tributyl phosphate and tripropyl phosphate, as penetration promoters. Nevertheless, there is still a need for further compounds with more advantageous properties from a variety of viewpoints.
  • the object of the invention is therefore to provide further advantageous substances with penetration-promoting properties for agrochemical active ingredients. It has now surprisingly been found that the solvent TBEP, in contrast to many other solvents in certain lower application rates and certain mixing ratios to the active ingredient to increase the penetration of herbicides and safeners, alone or in mixture, by the cuticle of the plant and thus to increase biological activity of plant protection products.
  • TBEP is already known as a solvent in correspondingly high application rates in crop protection, as in herbicides (see, for example, WO 01/47356 A1, EP 1251736 B1, WO 00/56146 A1, EP 1164842 B1) and insecticides (see, for example, JP 08291004 A, US 5674517 A). From GB 2022070 A TBEP is known for defoliation, wherein it was added in ratios of (TBEP: active ingredient) 2: 1 to 4: 1 to the herbicidal active ingredients. In the field of fungicides, the use of TBEP as a penetration promoter still seems to be unknown.
  • the invention relates to a method for promoting penetration, wherein the components
  • A one or more active substances from the group of herbicides and / or safeners
  • B tributoxyethyl phosphate
  • C optionally one or more emulsifiers, preferably from
  • the invention likewise relates to the use of the method described here, wherein the components are applied simultaneously or sequentially to the harmful plants.
  • herbicides include plant growth regulators, and from the group of safeners, as well as plant nutrients which have systemic properties, and as a combination partner candidate contact agents.
  • herbicides includes both herbicides and plant growth regulators unless the context otherwise indicates.
  • systemic agents i. those that are absorbed by the plant through the leaves or over the roots and passed on in the juice stream, the transport system or plant.
  • active compounds which have a Log P value of ⁇ 4 (determined according to EEC Directive 79/831 Annex V. A8 by HPLC, gradient method, acetonitrile / 0.1% aqueous phosphoric acid), in particular those having a Log P value of ⁇ 4 and> 0.1.
  • Examples of individual active substances from the group of herbicides, including plant growth regulators, and from the group of safeners are:

  • sulphonylureas are always to be understood as meaning, in addition to the neutral compounds, their salts with inorganic and / or organic counterions.

  • These salts are, for example, metal salts, in particular alkali metal salts or alkaline earth metal salts, in particular sodium and potassium salts, or else ammonium salts or salts with organic amines.
