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 preparation of such mixtures and compositions containing these mixtures.
  • Blends of triazolopyrimidine derivatives with dimethomorph 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 compounds II is therefore new.
  • EP-A 988 790 synergistic mixtures are fungicidally effective against various diseases of cereals, fruits and vegetables, such as. As mildew on wheat and barley or gray mold on apples.
  • fungicide Due to the specific cultivation conditions of rice plants, there are clearly different requirements for a rice fungicide than for fungicides used in cereal or fruit production. There are grave differences in the method of application: In rice crops, the fungicide is usually applied directly to, or shortly after sowing, the soil. The fungicide is absorbed into the plant via the roots and transported in the plant sap in the plant to the plant parts to be protected. High systemics are therefore essential for rice fungicides. In cereal or fruit growing, on the other hand, the fungicide is usually applied to the leaves or fruit, so in these cultures the systemics of the active ingredients play a much smaller role.
  • Rhizoctonia solani is the causative agents of the most important diseases of rice plants. Rhizoctonia solani is the only agriculturally significant pathogen within the subclass Agaricomycetidae. This fungus does not attack the plant like most other fungi via spores, but via a mycelium infection, For this reason, findings on the fungicidal effects of grain or fruit are not transferable to rice crops.
  • the pure active ingredients I and IIa or IIb are preferably employed in the preparation of the mixtures, to which other active substances can be added as needed against harmful fungi or other pests such as insects, spider animals or nematodes or else herbicidal or growth-regulating active substances or fertilizers ,
