Definitions

  • the present invention relates to fungicidal mixtures for controlling rice pathogens, comprising active components
  • the invention relates to a method for controlling rice pathogens with mixtures of the compound I with the compound II and the use of the compound I with the compound II for the preparation of such mixtures and agents which contain these mixtures.
  • the compound II, methoxyimino- (2-o-tolyloxymethyl-phenyl) -acetic acid methyl ester, its preparation and its action against harmful fungi is also known from the literature (EP-A 253213; common name: Kresoxim-Methyl).
  • Kresoxim-Methyl is established in the market, mainly as a cereal fungicide against mildew and rust diseases caused by Ascomycetes or Basidiomycetes.
  • Mixtures of triazolopyrimidine derivatives with kresoxim-methyl are generally known from EP-A 988 790.
  • Compound I is included in the general disclosure of this document, but is not explicitly mentioned. The combination of compound I with kresoxim-methyl is therefore new.
  • the synergistic mixtures known from EP-A 988 790 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.
  • a rice fungicide Due to the special cultivation conditions of rice plants, there are significantly different requirements for a rice fungicide than for fungicides that are used in cereal or fruit growing. There are differences in the application method: in addition to the foliar application used in many places, in modern rice cultivation the fungicide is applied directly to the soil 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. A high system is therefore essential for rice fungicides. In cereal or fruit growing, on the other hand, the fungicide is usually applied to the leaves or the fruits, so the systemics of the active ingredients play a significantly smaller role in these crops.
  • Rhizoctonia solani is the causative agents of the most important diseases of rice plants. Rhizoctonia solani is the only agronomically important pathogen within the subclass Aga comycetidae. This fungus does not attack the plant via spores like most other fungi, but through a mycelial infection.
