Definitions

  • the present invention describes a crop protection product and a method for producing the crop protection product according to the preamble of the first and seventh patent claims.
  • plant protection agents also generally referred to as pesticides
  • pesticides are known which are used to control plant pathogens which cause plant diseases on plant seeds and / or plants themselves and thus the loss of yield or crop failures that were feared in earlier times and which led to famine to prevent or minimize.
  • plant pathogen i.e. a bacterium, a fungus or a virus
  • the plant protection product is called fungicidal, bactericidal or virucidal.
  • plant protection agents or pesticides can be referred to as acaricidal, avicidal, herbicidal, insecticidal, miticidal, molluscicidal, nematicidal or rodenticidal.
  • Known pesticides or pesticides can contain organic or inorganic active ingredients.
  • pesticides or pesticides can contain alternative or additional chemical substances that have a plant-strengthening effect and thus have an indirect effect against plant pathogens.
  • the plant pathogen is a fungus or its spores, such as the so-called downy mildew in grapes (fungus: Plasmopara viticola) or the so-called apple scab in apples (fungus: Venturia inaequalis), where the plant protection product is used as the such is referred to as a fungicide.
  • fungicides or fungicides available on the market which contain synthetically produced active ingredients.
  • Such pesticides or fungicides based on synthetically produced active ingredients have a number of disadvantages such as a decrease in the effect on plant pathogens (i.e. so-called resistance development) and undesirable environmental influences, for example in water, and possibly also undesirable influences on humans.
  • Some commercially available pesticides therefore contain active substances based on the metals copper or potassium instead of synthetic active substances, i.e. in this case inorganic active substances.
  • active substances based on the metals copper or potassium instead of synthetic active substances, i.e. in this case inorganic active substances.
  • Such a known, copper-containing crop protection agent is, for example, Kocide Opti.
  • Such a known, potassium-containing crop protection agent is, for example, Armicarb.
  • Such crop protection agents containing copper or potassium have the disadvantage that an excessive accumulation of these metals in soils or waters can represent a burden for humans and the environment.
  • a plant protection agent which contains natural, i.e. substances that only occur in nature, as active ingredients and is intended to protect people and the environment as a result.
  • the natural active ingredient is a composition based on essential oils from a wide variety of plants, with a fungicidal effect against the phytopathogenic fungi Pythium aphanidermatum (root rot in soybeans, beets, paprika, pumpkinseed plants) or Rhizoctonia solani (potato pox) is described.
  • the present invention has set itself the task of providing a plant protection agent which is particularly gentle on humans and the environment and at the same time has a good effectiveness against plant pathogens.

  • the extract can be implemented in the form of a "cold extract” or a “hot extract”, or a combination of pressure and heat.
  • cold extract means a so-called macerate or cold water extract, whereby this manufacturing process advantageously allows volatile or thermally unstable ingredients to be extracted from vegetable raw materials. Left to stand for a long time and the liquid part, known as the "cold extract", is separated from the solid components.
  • the plant protection agent according to the invention is particularly suitable as a fungicide, in particular against the pathogenic fungi Venturia inaequalis (apple scab) and / or Plasmopara viticola (downy mildew).
