Abstract

METHOD FOR CONTROLLING PHYTOPATHOGENIC PESTS IN CEREALS. A method for controlling phytopathogenic pests in cereals, wherein the pest, its habitat, breeding site, its locations or the plants to be protected against pest attack, the soil or plant propagation material are treated with an effective amount of a fungicidal mixture comprising, as active components, 1) 1-[2-[[1-(4-chlorophenyl)pyrazol-3-yl]oxymethyl]-3-methylphenyl]-4-methyltetrazol-5-one as compound I, and 2) a fungicidal compound II selected from [2,2-bis(4-fluorophenyl)-1-methylethyl]2-[(3-acetoxy-4-methoxypyridine-2-carbonyl)amino]propanoate (compound II-1) and [(1S)-2,2-bis(4-fluorophenyl)-1-methylethyl] (2S)-2-[(3-acetoxy-4-methoxy-pyridine-2-carbonyl)amino]propanoate (compound II-2).

Description

[001] The present invention relates to fungicidal mixtures comprising: 1) 1-[2-[[1-(4-chlorophenyl)pyrazol-3-yl]oxymethyl]-3-methylphenyl]-4-methyltetrazol-5-one as compound I, and 2) a fungicidal compound II selected from [2,2-bis(4-fluorophenyl)-1-methylethyl]2-[(3-acetoxy-4-methoxypyridine-2-carbonyl)amino]propanoate (compound II-1) and [(1S)-2,2-bis(4-fluorophenyl)-1-methylethyl](2S)-2-[(3-acetoxy-4-methoxypyridine-2-carbonyl)amino]propanoate (compound II-2). [002] In addition, the invention relates to a method for controlling pests, including harmful animal and fungal pests, using the mixtures of the invention and the use of compound I of compound II for the preparation of such mixtures, and also compositions comprising such mixtures. [003] In addition, the present invention also comprises a method for protecting plant propagation material (preferably seeds) from harmful fungi or comprising contacting the plant propagation materials (preferably seeds) with a mixture of the invention in pesticide-effective quantities. [004] The term “plant propagation material” should be understood as designating all generative parts of the plant, such as seeds and vegetative plant material, such as cuttings and tubers (e.g., potatoes), which can be used for plant multiplication. This includes seeds, roots, fruits, tubers, bulbs, rhizomes, shoots, buds, and other plant parts, including seedlings and young plants, which are to be transplanted after germination or after emergence from the soil. These young plants may also be protected before transplanting by total or partial immersion or pouring treatment. In a particular preferred embodiment, the term propagation material denotes seeds. [005] In addition, the present invention also comprises a method for protecting plant propagation material (preferably seeds) from harmful fungi, comprising contacting the plant propagation materials (preferably seeds) with the mixture of the invention in pesticidally effective quantities. [006] In addition, the invention relates to a method for controlling harmful fungi using the mixtures of the invention and to the use of compounds present in the mixtures of the invention for the preparation of such mixtures, and also to compositions comprising such mixtures. [007] The present invention also relates to mixtures of plant-protective active ingredients that have synergistically enhanced plant health-enhancing activity and to a method of applying such mixtures of the invention to plants. [008] Compound I and analogues, as well as their pesticidal activity and methods for their production, are known from, for example, WO 2013/162072. Compound II, as well as their pesticidal activity and methods for their production, are known from WO 2016/122802 and WO 2016/109257. [009] A typical problem that arises in the field of pest control is the need to reduce dosage rates of the active ingredient in order to reduce or avoid adverse environmental or toxicological effects while still allowing effective pest control. [0010] In relation to the present invention, the term pests includes harmful fungi and animal pests. [0011] Another problem encountered concerns the need to have available pest control agents that are effective against a broad spectrum of harmful fungi and harmful animal pests. [0012] There is also a need for pest control agents that combine knock-down activity with prolonged control, i.e., fast action with long-lasting action. [0013] Another difficulty regarding the use of pesticides is that the repeated and exclusive application of an individual pesticide compound, in many cases, leads to a rapid selection of pests, meaning harmful animal and fungal pests, that have developed natural or adapted resistance against the active compound in question. Therefore, there is a need for pest control agents that help to prevent or overcome resistance. [0014] Another underlying problem of the present invention is the desire for compositions that improve plants, a process that is commonly and hereafter referred to as “plant health”. [0015] The term plant health encompasses various types of plant improvements that are not connected to pest control. For example, the advantageous properties that can be mentioned are: improved crop characteristics including: emergence, crop yield, protein content, oil content, starch content, more developed root system (improved root growth), better stress tolerance (e.g., against drought, heat, salt, UV, water, cold), reduced ethylene (reduced production and/or inhibition of reception), increased shoots, increased plant height, larger leaf blade, fewer dead basal leaves, stronger shoots, greener leaf color, pigment content, photosynthetic activity, less input required (such as fertilizers or water), fewer seeds required, more productive shoots, earlier flowering onset, earlier grain maturity, less plant backing (lodging), increased branch growth, increased plant vigor, greater ability of the plant to remain upright, and e
