All plants and plant parts can be treated in accordance with the invention. Plants are to be understood as meaning in the present context all plants and plant populations such as desired and undesired wild plants or crop plants (including naturally occurring crop plants). Crop plants can be plants which can be obtained by conventional plant breeding and optimization methods or by biotechnological and genetic engineering methods or by combinations of these methods, including the transgenic plants and including the plant cultivars protectable or not protectable by plant breeders' rights. Plant parts are to be understood as meaning all parts and organs of plants above and below the ground, such as shoot, leaf, flower and root, examples which may be mentioned being leaves, needles, stalks, stems, flowers, fruit bodies, fruits, seeds, roots, tubers and rhizomes. The plant parts also include harvested material, and vegetative and generative propagation material, for example cuttings, tubers, rhizomes, offshoots and seeds.
Treatment according to the invention of the plants and plant parts with the active compounds is carried out directly or by allowing the compounds to act on their surroundings, habitat or storage space by the customary treatment methods, for example by immersion, spraying, evaporation, fogging, scattering, painting on, injecting and, in the case of propagation material, in particular in the case of seed, also by applying one or more coats.
As already mentioned above, it is possible to treat all plants and their parts according to the invention. In a preferred embodiment, wild plant species and plant cultivars, or those obtained by conventional biological breeding methods, such as crossing or protoplast fusion, and parts thereof, are treated. In a further preferred embodiment, transgenic plants and plant cultivars obtained by genetic engineering methods, if appropriate in combination with conventional methods (Genetically Modified Organisms), and parts thereof, are treated. The terms “parts”, “parts of plants” and “plant parts” have been explained above.
Particularly preferably, plants of the plant cultivars which are in each case commercially available or in use are treated according to the invention. Plant cultivars are understood as meaning plants having novel properties (“traits”) which have been obtained by conventional breeding, by mutagenesis or by recombinant DNA techniques. These can be cultivars, bio- or genotypes.
Depending on the plant species or plant cultivars, their location and growth conditions (soils, climate, vegetation period, diet), the treatment according to the invention may also result in superadditive “synergistic”) effects. Thus, for example, reduced application rates and/or a widening of the activity spectrum and/or an increase in the activity of the substances and compositions which can be used according to the invention, better plant growth, increased tolerance to high or low temperatures, increased tolerance to drought or to water or soil salt content, increased flowering performance, easier harvesting, accelerated maturation, higher harvest yields, higher quality and/or a higher nutritional value of the harvested products, better storage stability and/or processability of the harvested products are possible, which exceed the effects which were actually to be expected.
The preferred transgenic plants or plant cultivars (obtained by genetic engineering) which are to be treated according to the invention include all plants which, by virtue of the genetic modification, received genetic material which imparts particularly advantageous, useful traits to these plants. Examples of such traits are better plant growth, increased tolerance to high or low temperatures, increased tolerance to drought or to water or soil salt content, increased flowering performance, easier harvesting, accelerated maturation, higher harvest yields, higher quality and/or a higher nutritional value of the harvested products, better storage stability and/or processability of the harvested products. Further and particularly emphasized examples of such traits are a better defence of the plants against animal and microbial pests, such as against insects, mites, phytopathogenic fungi, bacteria and/or viruses, and also increased tolerance of the plants to certain herbicidally active compounds. Examples of transgenic plants which may be mentioned are the important crop plants, such as cereals (wheat, rice), maize, soya beans, potatoes, sugar beet, tomatoes, peas and other vegetable varieties, cotton, tobacco, oilseed rape and also fruit plants (with the fruits apples, pears, citrus fruits and grapes), and particular emphasis is given to maize, soya beans, potatoes, cotton, tobacco and oilseed rape. Traits that are emphasized in particular are the increased defence of the plants against insects, arachnids, nematodes and slugs and snails by virtue of toxins formed in the plants, in particular those formed in the plants by the genetic material from Bacillus thuringiensis (for example by the genes CryIA(a), CryIA(b), CryIA(c), CryIIA, CryIIIA, CryIIIB2, Cry9c, Cry2Ab, Cry3Bb and CryIF and also combinations thereof) (referred to hereinbelow as “Bt plants”). Traits that are also particularly emphasized are the increased defence of the plants against fungi, bacteria and viruses by systemic acquired resistance (SAR), systemin, phytoalexins, elicitors and resistance genes and correspondingly expressed proteins and toxins. Traits that are furthermore particularly emphasized are the increased tolerance of the plants to certain herbicidally active compounds, for example imidazolinones, sulphonylureas, glyphosate or phosphinotricin (for example the “PAT” gene). The genes which impart the desired traits in question can also be present in combination with one another in the transgenic plants. Examples of “Bt plants” which may be mentioned are maize varieties, cotton varieties, soya bean varieties and potato varieties which are sold under the trade names YIELD GARD® (for example maize, cotton, soya beans), KnockOut® (for example maize), StarLink® (for example maize), Bollgard® (cotton), Nucotn® (cotton) and NewLeaf® (potato). Examples of herbicide-tolerant plants which may be mentioned are maize varieties, cotton varieties and soya bean varieties which are sold under the trade names Roundup Ready® (tolerance to glyphosate, for example maize, cotton, soya beans), Liberty Link® (tolerance to phosphinotricin, for example oilseed rape), IMI® (tolerance to imidazolinones) and STS® (tolerance to sulphonylureas, for example maize). Herbicide-resistant plants (plants bred in a conventional manner for herbicide tolerance) which may be mentioned include the varieties sold under the name Clearfield® (for example maize). Of course, these statements also apply to plant cultivars having these genetic traits or genetic traits still to be developed, which plant cultivars will be developed and/or marketed in the future.
The plants listed can be treated according to the invention in a particularly advantageous manner with the compounds according to the invention at a suitable concentration.

The active compounds according to the invention are also suitable for controlling arthropods, helminths and protozoae, which attack animals. Animals include agricultural livestock such as, for example, cattle, sheep, goats, horses, pigs, donkeys, camels, buffaloes, rabbits, chickens, turkeys, ducks, geese, cultured fish, honeybees. Moreover, animals include domestic animals—also referred to as companion animals—such as, for example, dogs, cats, cage birds, aquarium fish and what are known as experimental animals such as, for example, hamsters, guinea pigs, rats and mice.
By controlling these arthropods, helminths and/or protozoae, it is intended to reduce deaths and improve performance (in the case of meat, milk, wool, hides, eggs, honey and the like) and health of the host animal, so that more economical and simpler animal keeping is made possible by the use of the active compounds according to the invention.
For example, it is desirable to prevent or interrupt the uptake of blood by the parasites from the hosts (when applicable). Also, controlling the parasites may help to prevent the transmittance of infectious agents.
The term “controlling” as used herein with regard to the veterinary field, means that the active compounds are effective in reducing the incidence of the respective parasite in an animal infected with such parasites to innocuous levels. More specifically, “controlling”, as used herein, means that the active compound is effective in killing the respective parasite, inhibiting its growth, or inhibiting its proliferation.
Generally, when used for the treatment of animals the active compounds according to the invention can be applied directly. Preferably they are applied as pharmaceutical compositions which may contain pharmaceutically acceptable excipients and/or auxiliaries which are known in the art.
In the veterinary field and in animal keeping, the active compounds are applied (=administered) in the known manner by enteral administration in the form of, for example, tablets, capsules, drinks, drenches, granules, pastes, boluses, the feed-through method, suppositories; by parenteral administration, such as, for example, by injections (intramuscular, subcutaneous, intravenous, intraperitoneal and the like), implants, by nasal application, by dermal application in the form of, for example, bathing or dipping, spraying, pouring-on and spotting-on, washing, dusting, and with the aid of active-compound-comprising shaped articles such as collars, ear tags, tail tags, limb bands, halters, marking devices and the like. The active compounds may be formulated as shampoo or as suitable formulations usable in aerosols, unpressurized sprays, for example pump sprays and atomizer sprays.
When used for livestock, poultry, domestic animals and the like, the active compounds according to the invention can be applied as formulations (for example powders, wettable powders [“WP”], emulsions, emulsifiable concentrates [“EC”], flowables, homogeneous solutions, and suspension concentrates [“SC”]) which comprise the active compounds in an amount of from 1 to 80% by weight, either directly or after dilution (e.g. 100- to 10 000-fold dilution), or else as a chemical bath.
When used in the veterinary field the active compounds according to the invention may be used in combination with suitable synergists or other active compounds, such as for example, acaricides, insecticides, anthelmintics, anti-protozoal drugs.
In the present invention, a substance having an insecticidal action against pests including all of these is referred to as an insecticide.
When it is used as a pesticide, the active compounds of the present invention can be prepared in a form of a common preparation. Such preparation form may includes, for example, liquids, emulsions, wettable powders, granulated wettable powders, suspensions, powders, foams, pastes, tablets, granules, aerosols, natural or synthetic agents impregnated with the active compounds, microcapsules, coating agents for seeds, formulations equipped with a combustion devise (the combustion devise can be a smoke or fog cartridge, a can or a coil, etc.) and ULV (cold mist, warm mist), etc.
These formulations can be produced by known methods per se. For example, they can be prepared by mixing the active compounds with extenders, namely, liquid diluents or carriers; liquefied gas diluents or carriers; solid diluents or carriers and, optionally, with surfactants, namely, emulsifiers and/or dispersants and/or foam formers and the like.
In case of using water as an extender, for example, organic solvents can be used as auxiliary solvents.
Examples of the liquid diluents or carriers may include aromatic hydrocarbons (for example, xylene, toluene, alkylnaphthalene and the like), chlorinated aromatic hydrocarbons or chlorinated aliphatic hydrocarbons (for example, chlorobenzenes, ethylene chlorides, methylene chloride and the like), aliphatic hydrocarbons (for example, cyclohexane and the like, paraffins (mineral oil fractions and the like)), alcohols (for example, butanol, glycol and the like, and ethers and esters thereof), ketones (for example, acetone, methyl ethyl ketone, methyl isobutyl ketone, cyclohexanone and the like), strongly polar solvents (for example, dimethylformamide, dimethyl sulfoxide and the like), water, etc.
Liquefied gas diluent or carrier may includes those present as gas at atmospheric pressure and temperature, for example, bulan, propane, nitrogen gas, carbon dioxide, and aerosol propellant such as halogenated hydrocarbons.
Examples of the solid diluents may include ground natural minerals (for example, kaolins, clay, talc, chalk, quartz, attapulgite, montmorillonite or diatomaceous earth) and ground synthetic minerals (for example, highly dispersed silicic acid, alumina and silicate) and the like.
Examples of the solid carriers for granules may include crushed and fractionated rocks (for example, calcite, marble, pumice, sepiolite and dolomite), synthetic granules of inorganic or organic powders, and fine granules of organic materials (for example, sawdust, coconut shells, maize cobs and tobacco stalks) and the like.
Examples of the emulsifiers and/or foam formers may include nonionic and anionic emulsifiers [for example, polyoxyethylene fatty acid esters, polyoxyethylene fatty acid alcohol ethers (for example, alkylaryl polyglycol ether), alkyl sulfonates, alkyl sulfates and aryl sulfonates] and albumin hydrolysates and the like.
The dispersants include lignin sulfite waste liquor and methylcellulose.
Binders may also be used in the formulations (powders, granules and emulsion). Examples of the binders may include carboxymethyl cellulose, natural or synthetic polymers (for example, gum arabic, polyvinyl alcohol and polyvinyl acetate).
Colorants may also be used.
