Definitions

  • the present invention relates to novel fungicidal compositions for the treatment of diseases of useful plants caused by phytopathogens, especially by phytopathogenic fungi, and to a method of controlling diseases on useful plants caused by phytopathogens.
  • EP-0-310-550 discloses Cyprodinil ( ⁇ -cyclopropyl- ⁇ -methyl-pyrimidin ⁇ -yO-phenyl-amine), an anilinopyrimidine fungicide which is effective against a number of diseases caused by ascomycetes or deuteromycetes.
  • Penthiopyrad (/V-[2-(1 ,3-dimethylbutyl)-3-thienyl]-1-methyl-3- (trifluoromethyl)-i /-/-pyrazole-4-carboxamide) is a fungicide which is effective against a number of diseases caused by Ascomycetes, Basidiomycetes and Deuteromycetes.
  • Penthiopyrad Mixtures of Penthiopyrad with compounds, which act at the bci complex of the fungal mitochondrial respiratory electron transfer site, are described in WO 2006/036827.
  • Fungicidal compositions comprising a thiophene derivative and a second fungicide selected from Fludioxonil, an anilinopyrimidine, Fluazinam, lminoctadine albesilate and Polyoxin as well as their agrochemical uses are described in Japanese patent application JP-11- 302110.
  • the thiophene derivative is defined broadly and covers Penthiopyrad amongst many other thiophene derivatives.
  • the definition of the anilinopyrimidine encompasses - inter alia - Cyprodinil.
  • JP-1 1-302110 exemplifies Penthiopyrad-Fludioxonil-, Penthiopyrad- Mepanipyrim-, Penthiopyrad-lminoctadine albesilate- and Penthiopyrad-Fluazinam-mixtures and their synergistic efficacy to prevent gray mold disease (Botrytis cinerea) on peas.

  • a novel synergistic composition for control of diseases on useful plants or on propagation material thereof caused by phytopathogens that in addition to inert formulation adjuvants, comprises as active ingredient a mixture of component (A) and a synergistically effective amount of component (B), wherein component (A) is Cyprodinil; and component (B) is Penthiopyrad.
  • the active ingredient mixture according to the invention not only brings about the additive enhancement of the spectrum of action with respect to the phytopathogen to be controlled that was in principle to be expected but achieves a synergistic effect which extends the range of action of the component (A) and of the component (B) in two ways. Firstly, the rates of application of the component (A) and of the component (B) are iowered whilst the action remains equally good. Secondly, the active ingredient mixture still achieves a high degree of phytopathogen control even where the two individual components have become totally ineffective in such a low application rate range. This allows, on the one hand, a substantial broadening of the spectrum of phytopathogens that can be controlled and, on the other hand, increased safety in use.
  • the pesticidal compositions according to the invention can also have further surprising advantageous properties which can also be described, in a wider sense, as synergistic activity.
  • advantageous properties that may be mentioned are: broadening of the spectrum of fungicidal activity to other phytopathogens, for example to resistant strains; improved curativity; improved rainfastness; a reduction in the rate of application of the active ingredients; more advantageous degradability; improved toxicological and/or ecotoxicological behaviour; or improved characteristics of the useful plants including: 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, more productive tillers, earlier flowering, early grain maturity, less plant verse (lodging), increased shoot growth and improved plant vigor.
  • a further aspect of the instant invention is a synergistic composition for control of diseases on cereal plants caused by phytopathogens, that in addition to inert formulation adjuvants, comprises as active ingredient a mixture of component (A) and a synergistically effective amount of component (B), wherein component (A) is Cyprodinil; and component (B) is Penthiopyrad.
