Definitions

  • the present invention relates to fungicidal mixtures for controlling rice pathogens, containing as active components
  • the invention relates to a method for controlling rice pathogens with mixtures of the compound I with the compounds II and the use of the compound I with the compounds II for the production of such mixtures and agents which contain these mixtures.
  • the synergistic mixtures known from EP-A 988790 are fungicidally active against various diseases of cereals, fruits and vegetables, such as. B. powdery mildew on wheat and barley or gray mold on apples.
  • the present invention was based on mixtures which, with a reduced total amount of active ingredients applied, show an improved action against the rice pathogens.
  • the fungicide is usually applied to the soil directly at or shortly after sowing. The fungicide is absorbed into the plant via the roots and transported in the plant sap in the plant to the parts of the plant to be protected. In cereal or fruit growing, on the other hand, the fungicide is usually applied to the leaves or the fruits, which is why the systemics of the active ingredients play a significantly smaller role in these crops.
  • Rhizoctonia sasakii are the causative agents of the most important diseases of rice plants. Rhizoctonia sasakii is the only agronomically important pathogen within the Agaricomycetidae subclass. This fungus does not attack the plant via spores like most other fungi, but via a mycelial infection.
  • the present invention was based on mixtures which, with a reduced total amount of active ingredients applied, have an improved action against the harmful fungi.
  • Fungicides selected from the following group are particularly suitable as further active ingredients in the above sense:
  • Acylalanines such as benalaxyl, metalaxyl, ofurace, oxadixyl,
  • Amine derivatives such as aldimorph, dodemorph, fenpropimorph, fenpropidin, guazatine, iminoctadine, tridemorph,
