Definitions

• the present invention relates the use of strobilurin type compounds of formula I and the N-oxides and the salts thereof for combating phytopathogenic fungi containing an amino acid substitution F129L in the mitochondrial cytochrome b protein (also referred to as F129L muta tion in the mitochondrial cytochrome b gene) conferring resistance to Qo inhibitors (Qol), and to methods for combating such fungi.
• the invention also relates to novel compounds, processes for preparing these compounds, to compositions comprising at least one such compound, to plant health applications, and to seeds coated with at least one such compound.
• the present invention also relates to a method for controlling soybean rust fungi ( Phakopsora pachyrhizi) with the amino acid substitution F129L in the mitochondrial cytochrome b protein.
• Qo inhibitor includes any substance that is capable of diminishing and/or inhibiting respiration by binding to a ubihydroquinone oxidation center of a cytochrome bci complex in mitochondria.
• the oxidation center is typically located on the outer side of the inner mitochondrial membrane.
• Many of these compounds are also known as strobilurin-type or strobilurin analogue compounds.
• the mutation F129L in the mitochondrial cytochrome b (CYTB) gene shall mean any sub stitution of nucleotides of codon 129 encoding “F” (phenylalanine; e.g. TTT or TTC) that leads to a codon encoding “L” (leucine; e.g. TTA, TTG, TTG, CTT, CTC, CTA or CTG), for example the substitution of the first nucleotide of codon 129 T to ‘C’ (TTT to CTT), in the CYTB (cytochrome b) gene resulting in a single amino acid substitution in the position 129 from F to L in the cyto chrome b protein.
• Such F129L mutation is known to confer resistance to Qo inhibitors.
• Qol fungicides are conventionally used to control a number of fungal pathogens in crops.
• Qo inhibitors typically work by inhibiting respi ration by binding to a ubihydroquinone oxidation center of a cytochrome bci complex (electron transport complex III) in mitochondria. Said oxidation center is located on the outer side of the inner mitochondrial membrane.
• a prime example of the use of Qols includes the use of, for example, strobilurins on wheat for the control of Septoria tritici (also known as Mycosphaerella graminicola), which is the cause of wheat leaf blotch.
• soybean rust acquired a different genetic mutation in the cytochrome b gene causing a single amino acid substitution F129L which also confers resistance against Qol fungicides.
• new methods are desirable for controlling pathogen induced diseases in crops com prising plants subjected to pathogens containing a F129L mutation in the mitochondrial cyto chrome b gene conferring resistance to Qo inhibitors.
• the fungicidal activity of the known fungicidal strobilurin compounds is unsatisfactory, especially in case that a high proportion of the fungal pathogens contain a muta tion in the mitochondrial cytochrome b gene conferring resistance to Qo inhibitors.
• new fungicidally active compounds which are more effective, less toxic and/or environmentally safer. Based on this, it was also an object of the present invention to provide compounds having improved activity and/or a broader activity spectrum against phytopathogenic fungi and/or even further reduced toxicity against non target organisms such as vertebrates and invertebrates.
