Fungicidal mixtures of thiophene derivative

Abstract

Disclosed are fungicidal mixtures, compositions and methods for controlling plant diseases relating to combinations comprising (a)N-[2-(1,3-dimethyl-butyl)-3-thienyl]-1-methyl-3-(trifluoromethyl)-1H-pyrazole-4-methanamide (comprising all stereo isomers) or agriculture acceptable salt; and (b) at least one compound selected from general formula III or general formula IV, which acts on the bc<1> composition at respiration electron transport position of fungi mitochondrion; wherein W, A, B, D and R<5> are defined in the description, and their agriculture acceptable salt; and optional (c) at least one demethylase compound selected from sterol biosynthesis route and agriculture acceptable salt thereof..

Description

Technical field [0001] The present invention relates to fungicidal mixtures of certain thiophene derivatives and compositions comprising such mixtures and to methods of using these mixtures as fungicides. Background technique [0002] Control of plant diseases caused by fungal phytopathogens is very important to obtain high yield crops. Plant diseases damage ornamental plants, vegetables, field crops, cereals and fruit crops, causing significant yield reductions and thus increased consumer costs. Many products are commercially available for this purpose, but there is a need for new mixtures and compositions that are more effective, less expensive, less toxic, environmentally safer or have different modes of action. [0003] Growers will always need fungicides that effectively control plant fungi. Combinations of fungicides are often used to promote disease control and delay the development of resistance. There is a need to combine therapeutic, systemic and preventive cont...
