Abstract

The invention relates to insecticidal and acaricidal mixtures comprising certain cyclic ketoenols and agonists or antagonists of nicotinic acetylcholine receptors for protecting plants against attack by pests.

Description

This application is a divisional patent application of U.S. patent application Ser. No. 10/089,989, filed Apr. 2, 2002 and now U.S. Pat. No. 6,893,651, which in turn was the national stage of PCT Application No. PCT/EP00/09323 filed Sep. 25, 2000, which in turn claimed priority of German Patent Application Serial No. 199 48 129.6 filed Oct. 7, 1999.

The present invention relates to novel active compound combinations comprising, on the one hand, a known cyclic ketoenol and, on the other hand, further known insecticidally active compounds, which combinations have very good insecticidal and acaricidal properties.

It is already known that certain cyclic ketoenols can be employed for controlling animal pests such as insects and undesirable acarids (cf. EP-A-528 156). The activity of these substances is good, but sometimes unsatisfactory at low application rates.

Furthermore, it is also known that agonists and antagonists of nicotinic acetylcholine receptors can be used for controlling insects.

It has now been found that mixtures of cyclic ketoenols of the formula (I)

The active compound content of the use forms prepared from the commercially available formulations can vary within wide limits. The active compound concentration of the use forms can be from 0.0000001 to 95% by weight of active compound, preferably between 0.0001 and 1% by weight.

The active compound mixtures can be converted into the customary formulations, such as solutions, emulsions, suspensions, powders, foams, pastes, granules, aerosols, active-compound-impregnated natural and synthetic materials, very fine encapsulations in polymeric substances and in coating compositions for seed, furthermore into formulations with smokes, such as fumigating cartridges, fumigating cans, fumigating coils and the like, and also ULV cold mist and warm mist formulations.

These formulations are prepared in a known manner, for example by mixing the active compounds with extenders, that is liquid solvents, pressurized liquefied gases and/or solid carriers, optionally with the use of surfactants, that is emulsifiers and/or dispersing agents, and/or foam-formers. If the extender used is water, it is also possible to use for example organic solvents as auxiliary solvents. Suitable liquid solvents are essentially: aromatics, such as xylene, toluene or alkylnaphthalenes, chlorinated aromatics or chlorinated aliphatic hydrocarbons, such as chlorobenzenes, chloroethylenes or methylene chloride, aliphatic hydrocarbons, such as cyclohexane or paraffins, for example mineral oil fractions, alcohols, such as butanol or glycol and also their ethers and esters, ketones, such as acetone, methyl ethyl ketone, methyl isobutyl ketone or cyclohexanone, strongly polar solvents, such as dimethylformamide and dimethyl sulphoxide, and also water; by liquefied gaseous extenders or carriers are meant liquids which are gaseous at ambient temperature and under atmospheric pressure, for example aerosol propellant, such as halogenated hydrocarbons and also butane, propane, nitrogen and carbon dioxide; suitable solid carriers are: for example, ground natural minerals, such as kaolins, clays, talc, chalk, quartz, attapulgite, montmorillonite or diatomaceous earth, and ground synthetic minerals, such as finely divided silica, alumina and silicates; suitable solid carriers for granules are: for example, crushed and fractionated natural rocks such as calcite, marble, pumice, sepiolite and dolomite, and also synthetic granules of inorganic and organic meals, and granules of organic material such as sawdust, coconut shells, maize cobs and tobacco stalks; suitable emulsifiers and/or foam-formers are: for example, nonionic and anionic emulsifiers, such as polyoxyethylene fatty acid esters, polyoxyethylene fatty alcohol ethers, for example alkylaryl polyglycol ethers, alkylsulphonates, alkyl sulphates, arylsulphonates and also protein hydrolysates; suitable dispersing agents are: for example, lignin-sulphite waste liquors and methylcellulose.

Tackifiers such as carboxy-methylcellulose and natural and synthetic polymers in the form of powders, granules or latices, such as gum arabic, polyvinyl alcohol and polyvinyl acetate, and also natural phospholipids, such as cephalins and lecithins, and synthetic phospholipids, can be used in the formulations. Other possible additives are mineral and vegetable oils.

It is possible to use colorants such as inorganic pigments, for example iron oxide, titanium oxide and Prussian Blue, and organic dyestuffs, such as alizarin dyestuffs, azo dyestuffs and metal phthalocyanine dyestuffs, and trace nutrients such as salts of iron, manganese, boron, copper, cobalt, molybdenum and zinc.

The formulations in general comprise between 0.1 and 95 percent by weight of active compound mixture, preferably between 0.5 and 90 percent by weight of active compound mixture.

The mixtures according to the invention can be applied via the leaves.

According to the invention, it is possible to treat all plants and parts of plants. By plants are to be understood here 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 breeding and optimization methods or by biotechnological and genetic engineering methods or combinations of these methods, including transgenic plants and including plant cultivars which can or cannot be protected by plant breeder certificates. Parts of plants are to be understood as meaning all above-ground and below-ground parts and organs of plants, such as shoot, leaf, flower and root, examples which may be mentioned being leaves, needles, stems, trunks, flowers, fruit bodies, fruits and seeds and also roots, tubers and rhizomes. Parts of plants also include harvested plants and vegetative and generative propagation material, for example seedlings, tubers, rhizomes, cuttings and seeds.

The treatment of the plants and parts of plants according to the invention with the active compounds is carried out directly or by action on their environment, habitat or storage area according to customary treatment methods, for example by dipping, spraying, evaporating, atomizing, broadcasting, brushing-on and, in the case of propagation material, in particular in the case of seeds, furthermore by one- or multi-layer coating.

When using the active compound combinations according to the invention, the application rates can be varied within a relatively wide range, depending on the type of application. In the treatment of parts of plants, the active compound combination application rates are generally between 0.1 and 10,000 g/ha, preferably between 10 and 1000 g/ha.

The good insecticidal and acaricidal action of the active compound combinations according to the invention is evident from the examples below. While the individual active compounds exhibit weaknesses with regard to the activity, the combinations have an activity which exceeds a simple addition of activities.

A synergistic effect of insecticides and acaricides is always present when the activity of the active compound combinations exceeds the total of the activities of the active compounds when applied individually.

The expected activity for a given combination of two active compounds can be calculated as follows (after S. R. Colby, Weeds 15 (1967), 20-22):

  • If
  • X is the efficacy when applying the active compound A at an application rate of m g/ha or in a concentration of m ppm,
  • Y is the efficacy when applying the active compound B at an application rate of n g/ha or at a concentration of n ppm and
  • E is the efficacy when applying the active compounds A and B at application rates of m and n g/ha or at a concentration of m and n ppm,
  • then

E = X + Y - X · Y 100

The efficacy is calculated in %. 0% is an efficacy which corresponds to that of the control, whereas an efficacy of 100% means that no infection is observed.

If the actual activity exceeds the calculated value, then the activity of the combination is superadditive, i.e. a synergistic effect exists. In this case, the efficacy which was actually observed must be greater than the value for the expected efficacy (E) calculated from the abovementioned formula.
