  • Y means the efficiency when using the active ingredient B in an application rate of n g / ha
  • Z means the efficiency when using the active ingredient C in an application rate of r_g / ha
  • ⁇ ⁇ means the efficiency of the use of the active compounds A and B in application rates of m and n g / ha, and
  • E2 means the efficiency when using the active compounds A and B and C at application rates of m and n and r g / ha,

Abstract

La présente invention concerne de nouvelles combinaisons de principes actifs comprenant au moins trois composants fongicides A, B et C. A, B et C peuvent être choisis parmi les composés suivants : A) les composés de formule générale (I), dans laquelle les résidus R<SUP>1</SUP> et R<SUP>2</SUP> ont les significations indiquées dans la description, B) l'azoxystrobine (II), le fludioxonil (III), C) un triazole de formule générale (IV), ou le triazoxyde (V), le silthiofam (VI), le penthiopyrad (VII). Les combinaisons de principes actifs conviennent très bien pour lutter contre des champignons phytopathogènes indésirables. En particulier, les combinaisons de principes actifs selon l'invention sont appropriées pour le traitement de semences.
