Definitions

  • the present invention relates to mixtures of pesticidally active ingredients and to methods of using the mixtures in the field of agriculture.
  • WO2010/020522 discloses that certain dihydropyrrole compounds have insecticidal activity.
  • the present invention provides pesticidal mixtures comprising a component A and a component B, wherein component A is a compound of formula I
  • one of Y 1 and Y 2 is S, SO or S0 2 and the other is CH 2 ;
  • L is a direct bond or methylene
  • a 1 and A 2 are C-H, or one of A 1 and A 2 is C-H and the other is N;
  • R 1 is hydrogen or methyl
  • R 2 is chlorodifluoromethyl or trifluoromethyl

  • R 4 is methyl or chlorine
  • R 5 is hydrogen
  • component B is a fungicide selected from
  • a strobilurin fungicide selected from the group consisting of:
  • Metominostrobin Orysastrobin, Picoxystrobin, Pyraclostrobin, Trifloxystrobin;

  • Compounds of formula I are known to have insecticidal activity, whereas compounds of component B are known to have fungicidal activity.
  • Certain active ingredient mixtures of a compound of formula I and a fungicide can enhance the spectrum of action with respect to the pest to be controlled, e.g. the animal pest and/or the fungal pest.
  • the combination of A and B may cause an increase in the insecticidal action of component A and/or an increase in the fungicidal action of component B which would be expected from each component when used alone.

  • the pesticidal mixtures according to the invention can have further advantageous properties which can also be described, in a wider sense, as synergistic activity. Examples of such
  • advantageous properties are: a broadening of the spectrum of activity; a reduction in the rate of application of the active ingredients; adequate pest control with the aid of the mixtures according to the invention, sometimes even at a rate of application at which the individual compounds are totally ineffective; advantageous behaviour during formulation and/or upon application, for example upon grinding, sieving, emulsifying, dissolving or dispensing; increased storage stability; improved stability to light; more advantageous degradability; improved toxicological and/or ecotoxicological behaviour; improved characteristics of the useful plants including: emergence, crop yields, more developed root system, tillering increase, increase in plant height, bigger leaf blade, less dead basal leaves, stronger tillers, greener leaf colour, less fertilizers needed, less seeds needed, more productive tillers, earlier flowering, early grain maturity, less plant verse (lodging), increased shoot growth, improved plant vigor, and early germination; or any other advantages familiar to a person skilled in the art.
