One typical problem arising in the field of pest control lies in the need to reduce the dosage rates of the active ingredient in order to reduce or avoid unfavorable environmental or toxicological effects whilst still allowing effective pest control.
The term “phytopathogenic harmful fungi” is hereinbelow also abbreviated as “harmful fungi”.
Another problem encountered concerns the need to have available pest control agents which are effective against a broad spectrum of harmful fungi.
There also exists the need for pest control agents that combine knock-down activity with prolonged control, that is, fast action with long lasting action.
Another difficulty in relation to the use of pesticides is that the repeated and exclusive application of an individual pesticidal compound leads in many cases to a rapid selection of harmful fungi, which have developed natural or adapted resistance against the active compound in question. Therefore there is a need for pest control agents that help prevent or overcome resistance.
Another problem underlying the present invention is the desire for compositions that improve plants, a process which is commonly and hereinafter referred to as “plant health”.
The term plant health comprises various sorts of improvements of plants that are not connected to the control of pests. For example, advantageous properties that may be mentioned are improved crop characteristics including: emergence, crop yields, protein content, oil content, starch content, more developed root system (improved root growth), improved stress tolerance (e.g. against drought, heat, salt, UV, water, cold), reduced ethylene (reduced production and/or inhibition of reception), tillering increase, increase in plant height, bigger leaf blade, less dead basal leaves, stronger tillers, greener leaf color, pigment content, photosynthetic activity, less input needed (such as fertilizers or water), less seeds needed, more productive tillers, earlier flowering, early grain maturity, less plant verse (lodging), increased shoot growth, enhanced plant vigor, increased plant stand and early and better germination; or any other advantages familiar to a person skilled in the art.
If used in connection with the treatment of plant propagation material (preferably seeds) the term “plant health” is equivalent with “seed vitality”. Seed vitality manifests itself in a variety of factors. Examples of factors which are manifestations of the plant's vitality are:
Preferably, the term “Seed vitality” denotes plant stand density, storability of seeds and/or germination behavior.
A further object of various efforts in crop protection is to increase the yield of plants. “Yield” is to be understood as any plant product of economic value that is produced by the plant such as grains, fruits in the proper sense, vegetables, nuts, grains, seeds, wood (e.g. in the case of silviculture plants) or even flowers (e.g. in the case of gardening plants, ornamentals). The plant products may in addition be further utilized and/or processed after harvesting.
According to the present invention, “increased yield” of a plant, in particular of an agricultural, silvicultural and/or horticultural plant, preferably agricultural plant means that the yield of a product of the respective plant is increased by a measurable amount over the yield of the same product of the plant produced under the same conditions, but without the application of the mixture according to the invention.
Increased yield can be characterized, among others, by following improved properties of the plant:
According to the present invention, the yield is increased by at least 2%, preferable by at least 4%, more preferred by at least 8%, even more preferred by at least 16%.
It has to be emphasized that the above effects of the mixture of the invention or of compound I when used alone, i.e. enhanced crop yield of the plant, also are present when the plant is not under biotic stress and in particular when the plant is not under pest pressure, such as fungi or insect stress. It is evident that a plant suffering from pest attack produces a smaller biomass and a smaller crop yield as compared to a plant which has been subjected to curative or preventive treatment against the pest and which can grow without the damage caused by the biotic stress factor. However, the use and the method according to the invention lead to an enhanced crop yield even in the absence of any biotic stress and in particular in the absence of any pest. This means that the positive effect of the mixture of the invention or of compound I used alone on the crop yield cannot be explained just by the pesticidal activities of the mixture, but is based on further activity profiles. But of course, plants under biotic stress can be treated, too, according to the methods of the present invention.
EP 2119361 and EP 2223599 disclose several pesticidal mixtures which may, inter alia, comprise the compound of formula I.
However, the outstanding synergistic fungicidal and/or plant health action of the specific inventive mixtures as well as the as defined at the outset are not disclosed therein, also not, that such combinations might have and especially its suitability for seed treatment purposes.
It was therefore an object of the present invention to provide pesticidal mixtures which solve the problems of reducing the dosage rate and/or enhancing the spectrum of activity and/or combining knock-down activity with prolonged control and/or to resistance management and/or promoting the health of plants.
It was also an object of the present invention to provide methods of increasing the health of plants.
We have found that this object is in part or in whole achieved by the complex mixtures comprising the active compounds defined in the outset.
Herein, we have found a method for increasing the health of plants, wherein the plant, the locus where the plant is growing or is expected to grow or plant propagation material from which the plant grows is treated with an effective amount of a compound of formula I, wherein preferably the plant propagation material from which the plant grows is treated with an effective amount of a compound of formula I. Such latter treatment of plant propagation material leads to increase in seed vitality.
It has been found that the mixtures as defined in the outset show markedly enhanced action against harmful pests, such as harmful fungi or animal pests, preferably harmful fungi, compared to the control rates that are possible with the individual compounds and/or is suitable for improving the health of plants when applied to plants, parts of plants, plant propagation materials (preferably seeds), or at their locus of growth.
It has been found that the action of the inventive mixtures goes far beyond the pesticidal, such as fungicidal or insecticidal, preferably fungicidal, and/or plant health improving action of the active compounds present in the mixture alone (synergism).
In particular, it has been found that the action of the inventive mixtures goes far beyond the pesticidal, such as fungicidal or insecticidal, preferably fungicidal, and/or plant health improving action of the active compounds present in the mixture alone (synergism) if applied as a seed treatment.
These mixtures are also suitable for improving the health of plants when applied to plants, parts of plants, seeds, or at their locus of growth, preferably to plants and plant propagation material, more preferably to seeds.
Moreover, we have found that simultaneous, that is joint or separate, application of the compound I and compound II or successive application of the compound I and compound II allows enhanced control of harmful pests, such as harmful fungi or animal pests, preferably harmful fungi, compared to the control rates that are possible with the individual compounds (synergistic mixtures).
Moreover, we have found that simultaneous, that is joint or separate, application of the compound I and compound II or successive application of the compound I and compound II provides enhanced plant health effects compared to the plant health effects that are possible with the individual compounds (synergistic mixtures wherein the synergism is plant health synergism).

For example, the plant(s) may be sprayed with a composition of this invention either before or after being treated with the fertilizers.
As already explained above, the mixture of the invention is not restricted to a physical mixture. Thus the compounds I and II can be applied as a physical mixture or separately. The compounds contained in the mixtures as defined above can be applied simultaneously, that is jointly or separately, or in succession, the sequence, in the case of separate application, generally not having any effect on the result of the control measures.
According to this invention, the compound I and compound II is to be understood to denote, that at least the compound I and compound II occur simultaneously at the site of action (i.e. the pests, such as harmful fungi and animal pests such as insects, arachnids or nematodes to be controlled or their habitats such as infected plants, plant propagation materials, particularly seeds, surfaces, materials or the soil as well as plants, plant propagation materials, particularly seeds, soil, surfaces, materials or rooms to be protected from fungal or animal attack) in a effective amount.
This can be obtained by applying the compound I and compound II simultaneously, either jointly (e. g. as tank-mix) or separately, or in succession, wherein the time interval between the individual applications is selected to ensure that the active substance applied first still occurs at the site of action in a sufficient amount at the time of application of the further active substance(s). The order of application is not essential for working of the present invention.
In the mixtures of the present invention, the weight ratio of the compounds generally depends from the properties of the compounds of the inventive mixtures.
The compounds of the inventive mixtures can be used individually or already partially or completely mixed with one another to prepare the composition according to the invention. It is also possible for them to be packaged and used further as combination composition such as a kit of parts.

E. g., kits may include the compound I and compound II and/or an adjuvant component and/or a further pesticidal compound (e.g. insecticide or herbicide) and/or a growth regulator component). One or more of the components may already be combined together or pre-formulated. In those embodiments where more than two components are provided in a kit, the components may already be combined together and as such are packaged in a single container such as a vial, bottle, can, pouch, bag or canister. In other embodiments, two or more components of a kit may be packaged separately, i. e., not pre-formulated. As such, kits may include one or more separate containers such as vials, cans, bottles, pouches, bags or canisters, each container containing a separate component for an agrochemical composition. In both forms, a component of the kit may be applied separately from or together with the further components or as a component of a combination composition according to the invention for preparing the composition according to the invention.
The user applies the composition according to the invention usually from a predosage device, a knapsack sprayer, a spray tank or a spray plane. Here, the agrochemical composition is made up with water and/or buffer to the desired application concentration, it being possible, if appropriate, to add further auxiliaries, and the ready-to-use spray liquor or the agrochemical composition according to the invention is thus obtained. Usually, 50 to 500 liters of the ready-to-use spray liquor are applied per hectare of agricultural useful area, preferably 100 to 400 liters.
According to one embodiment, individual compounds of the inventive mixtures formulated as composition (or formulation) such as parts of a kit or parts of the inventive mixture may be mixed by the user himself in a spray tank and further auxiliaries may be added, if appropriate (tank mix).
In a further embodiment, either individual compounds of the inventive mixtures formulated as composition or partially premixed components, e. g. components comprising the compound I and compound II may be mixed by the user in a spray tank and further auxiliaries and additives may be added, if appropriate (tank mix).
In a further embodiment, either individual components of the composition according to the invention or partially premixed components, e. g. components comprising the compound I and compound II, can be applied jointly (e.g. after tankmix) or consecutively.

The inventive mixtures are also suitable for controlling fungal diseases occurring in the protection of materials (e. g. wood, paper, paint dispersions, fiber or fabrics) and in the protection of stored products. The term “protection of materials” is to be understood to denote the protection of technical and non-living materials, such as adhesives, glues, wood, paper and paperboard, textiles, leather, paint dispersions, plastics, coiling lubricants, fiber or fabrics, against the infestation and destruction by harmful microorganisms, such as fungi and bacteria. As to the protection of wood and other materials, the particular attention is paid to the following harmful fungi: Ascomycetes such as Ophiostoma spp., Ceratocystis spp., Aureobasidium pullulans, Sclerophoma spp., Chaetomium spp., Humicola spp., Petriella spp., Trichurus spp.; Basidiomycetes such as Coniophora spp., Coriolus spp., Gloeophyllum spp., Lentinus spp., Pleurotus spp., Poria spp., Serpula spp. and Tyromyces spp., Deuteromycetes such as Aspergillus spp., Cladosporium spp., Penicillium spp., Trichorma spp., Alternaria spp., Paecilomyces spp. and Zygomycetes such as Mucor spp., and in addition in the protection of stored products and harvest the following yeast fungi are worthy of note: Candida spp. and Saccharomyces cerevisiae.
They are particularly important for controlling a multitude of harmful fungi on various cultivated plants, such as bananas, cotton, vegetable species (for example cucumbers, beans and cucurbits), barley, grass, oats, coffee, potatoes, corn, fruit species, rice, rye, soya, tomatoes, grapevines, wheat, ornamental plants, sugar cane and also on a large number of plant propagation materials (preferably seeds).
“Locus” means a plant, plant propagation material (preferably seed), soil, area, material or environment in which a pest is growing or may grow.
In general, “pesticidally effective amount” means the amount of the inventive mixtures or of compositions comprising the mixtures needed to achieve an observable effect on growth, including the effects of necrosis, death, retardation, prevention, and removal, destruction, or otherwise diminishing the occurrence and activity of the target organism. The pesticidally effective amount can vary for the various mixtures/compositions used in the invention. A pesticidally effective amount of the mixtures/compositions will also vary according to the prevailing conditions such as desired pesticidal effect and duration, weather, target species, locus, mode of application, and the like.
As said above, the present invention comprises a method for improving the health of plants, wherein the plant, the locus where the plant is growing or is expected to grow or plant propagation material, from which the plant grows, is treated with an plant health effective amount of an inventive mixture.
The term “plant health effective amount” denotes an amount of the inventive mixtures, which is sufficient for achieving plant health effects as defined herein. More exemplary information about amounts, ways of application and suitable ratios to be used is given below. Anyway, the skilled artisan is well aware of the fact that such an amount can vary in a broad range and is dependent on various factors, e.g. the treated cultivated plant or material and the climatic conditions.
The term “effective amount” comprises the terms “plant health effective amount” and/or “pesticidally effective amount” as the case may be.
When preparing the mixtures, it is preferred to employ the pure active compounds, to which further active compounds against pests, such as insecticides, herbidices, fungicides or else herbicidal or growth-regulating active compounds or fertilizers can be added as further active components according to need.
The inventive mixtures are employed by treating the fungi or the plants, plant propagation materials (preferably seeds), materials or soil to be protected from fungal attack with a pesticidally effective amount of the active compounds I and II. The application can be carried out both before and after the infection of the materials, plants or plant propagation materials (preferably seeds) by the harmful fungi.
Preferably, the inventive mixtures are employed by treating the fungi or the plants or soil to be protected from pesticidal attack via foliar application with a pesticidally effective amount of the active compounds. Also herein, the application can be carried out both before and after the infection of the plants by the harmful fungi.
In the method of combating harmful fungi depending on the type of compound and the desired effect, the application rates of the mixtures according to the invention are from 0, 1 g/ha to 10000 g/ha, preferably 2 g/ha to 2500 g/ha, more preferably from 5 to 1000 g/ha, most preferably from 10 to 750 g/ha, in particular from 20 to 500 g/ha.
Plants and as well as the propagation material of said plants, which can be treated with the inventive mixtures include all genetically modified plants or transgenic plants, e.g. crops which tolerate the action of herbicides or fungicides or insecticides owing to breeding, including genetic engineering methods, or plants which have modified characteristics in comparison with existing plants, which can be generated for example by traditional breeding methods and/or the generation of mutants, or by recombinant procedures.
For example, mixtures according to the present invention can be applied (as seed treatment, spray treatment, in furrow or by any other means) also to plants which have been modified by breeding, mutagenesis or genetic engineering including but not limiting to agricultural biotech products on the market or in development (cf. http://www.bio.org/speeches/pubs/er/agri_products.asp). Genetically modified plants are plants, which genetic material has been so modified by the use of recombinant DNA techniques that under natural circumstances cannot readily be obtained by cross breeding, mutations or natural recombination. Typically, one or more genes have been integrated into the genetic material of a genetically modified plant in order to improve certain properties of the plant. Such genetic modifications also include but are not limited to targeted post-transitional modification of protein(s), oligo- or polypeptides e. g. by glycosylation or polymer additions such as prenylated, acetylated or farnesylated moieties or PEG moieties.
Plants that have been modified by breeding, mutagenesis or genetic engineering, e. g. have been rendered tolerant to applications of specific classes of herbicides, such as hydroxyphenylpyruvate dioxygenase (HPPD) inhibitors; acetolactate synthase (ALS) inhibitors, such as sulfonyl ureas (see e. g. U.S. Pat. No. 6,222,100, WO 01/82685, WO 00/26390, WO 97/41218, WO 98/02526, WO 98/02527, WO 04/106529, WO 05/20673, WO 03/14357, WO 03/13225, WO 03/14356, WO 04/16073) or imidazolinones (see e. g. U.S. Pat. No. 6,222,100, WO 01/82685, WO 00/026390, WO 97/41218, WO 98/002526, WO 98/02527, WO 04/106529, WO 05/20673, WO 03/014357, WO 03/13225, WO 03/14356, WO 04/16073); enolpyruvylshikimate-3-phosphate synthase (EPSPS) inhibitors, such as glyphosate (see e. g. WO 92/00377); glutamine synthetase (GS) inhibitors, such as glufosinate (see e.g. EP-A 242 236, EP-A 242 246) or oxynil herbicides (see e. g. U.S. Pat. No. 5,559,024) as a result of conventional methods of breeding or genetic engineering. Several cultivated plants have been rendered tolerant to herbicides by conventional methods of breeding (mutagenesis), e. g. Clearfield® summer rape (Canola, BASF SE, Germany) being tolerant to imidazolinones, e. g. imazamox. Genetic engineering methods have been used to render cultivated plants such as soybean, cotton, corn, beets and rape, tolerant to herbicides such as glyphosate and glufosinate, some of which are commercially available under the trade names RoundupReady® (glyphosate-tolerant, Monsanto, U.S.A.) and LibertyLink® (glufosinate-tolerant, Bayer CropScience, Germany).
Furthermore, plants are also covered that are by the use of recombinant DNA techniques capable to synthesize one or more insecticidal proteins, especially those known from the bacterial genus Bacillus, particularly from Bacillus thuringiensis, such as δ-endotoxins, e. g. CryIA(b), CryIA(c), CryIF, CryIF(a2), CryIIA(b), CryIIIA, CryIIIB(b1) or Cry9c; vegetative insecticidal proteins (VIP), e. g. VIP1, VIP2, VIP3 or VIP3A; insecticidal proteins of bacteria colonizing nematodes, e. g. Photorhabdus spp. or Xenorhabdus spp.; toxins produced by animals, such as scorpion toxins, arachnid toxins, wasp toxins, or other insect-specific neurotoxins; toxins produced by fungi, such Streptomycetes toxins, plant lectins, such as pea or barley lectins; agglutinins; proteinase inhibitors, such as trypsin inhibitors, serine protease inhibitors, patatin, cystatin or papain inhibitors; ribosome-inactivating proteins (RIP), such as ricin, maize-RIP, abrin, luffin, saporin or bryodin; steroid metabolism enzymes, such as 3-hydroxysteroid oxidase, ecdysteroid-IDP-glycosyl-transferase, cholesterol oxidases, ecdysone inhibitors or HMG-CoA-reductase; ion channel blockers, such as blockers of sodium or calcium channels; juvenile hormone esterase; diuretic hormone receptors (helicokinin receptors); stilben synthase, bibenzyl synthase, chitinases or glucanases. In the context of the present invention these insecticidal proteins or toxins are to be understood expressly also as pre-toxins, hybrid proteins, truncated or otherwise modified proteins. Hybrid proteins are characterized by a new combination of protein domains, (see, e. g. WO 02/015701). Further examples of such toxins or genetically modified plants capable of synthesizing such toxins are disclosed, e. g., in EP-A 374 753, WO 93/007278, WO 95/34656, EP-A 427 529, EP-A 451 878, WO 03/18810 and WO 03/52073. The methods for producing such genetically modified plants are generally known to the person skilled in the art and are described, e. g. in the publications mentioned above. These insecticidal proteins contained in the genetically modified plants impart to the plants producing these proteins tolerance to harmful pests from all taxonomic groups of arthropods, especially to beetles (Coleoptera), two-winged insects (Diptera), and moths (Lepidoptera) and to nematodes (Nematoda). Genetically modified plants capable to synthesize one or more insecticidal proteins are, e. g., described in the publications mentioned above, and some of which are commercially available such as YieldGard® (corn cultivars producing the Cry1Ab toxin), YieldGard® Plus (corn cultivars producing Cry1Ab and Cry3Bb1 toxins), Starlink® (corn cultivars producing the Cry9c toxin), Herculex® RW (corn cultivars producing Cry34Ab1, Cry35Ab1 and the enzyme Phosphinothricin-N-Acetyltransferase [PAT]); NuCOTN® 33B (cotton cultivars producing the Cry1Ac toxin), Bollgard® I (cotton cultivars producing the Cry1Ac toxin), Bollgard® II (cotton cultivars producing Cry1Ac and Cry2Ab2 toxins); VIPCOT® (cotton cultivars producing a VIP-toxin); NewLeaf® (potato cultivars producing the Cry3A toxin); Bt-Xtra®, NatureGard®, KnockOut®, BiteGard®, Protecta®, Bt11 (e. g. Agrisure® CB) and Bt176 from Syngenta Seeds SAS, France, (corn cultivars producing the Cry1Ab toxin and PAT enzyme), MIR604 from Syngenta Seeds SAS, France (corn cultivars producing a modified version of the Cry3A toxin, c.f. WO 03/018810), MON 863 from Monsanto Europe S.A., Belgium (corn cultivars producing the Cry3Bb1 toxin), IPC 531 from Monsanto Europe S.A., Belgium (cotton cultivars producing a modified version of the Cry1Ac toxin) and 1507 from Pioneer Overseas Corporation, Belgium (corn cultivars producing the Cry1F toxin and PAT enzyme).
Furthermore, plants are also covered that are by the use of recombinant DNA techniques capable to synthesize one or more proteins to increase the resistance or tolerance of those plants to bacterial, viral or fungal pathogens. Examples of such proteins are the so-called “pathogenesis-related proteins” (PR proteins, see, e. g. EP-A 392 225), plant disease resistance genes (e. g. potato cultivars, which express resistance genes acting against Phylophthora infestans derived from the mexican wild potato Solanum bulbocastanum) or T4-lysozym (e. g. potato cultivars capable of synthesizing these proteins with increased resistance against bacteria such as Erwinia amylvora). The methods for producing such genetically modified plants are generally known to the person skilled in the art and are described, e. g. in the publications mentioned above.
Furthermore, plants are also covered that are by the use of recombinant DNA techniques capable to synthesize one or more proteins to increase the productivity (e. g. bio mass production, grain yield, starch content, oil content or protein content), tolerance to drought, salinity or other growth-limiting environmental factors or tolerance to pests and fungal, bacterial or viral pathogens of those plants.
Furthermore, plants are also covered that contain by the use of recombinant DNA techniques a modified amount of substances of content or new substances of content, specifically to improve human or animal nutrition, e. g. oil crops that produce health-promoting long-chain omega-3 fatty acids or unsaturated omega-9 fatty acids (e. g. Nexera® rape, DOW Agro Sciences, Canada).
Furthermore, plants are also covered that contain by the use of recombinant DNA techniques a modified amount of substances of content or new substances of content, specifically to improve raw material production, e. g. potatoes that produce increased amounts of amylopectin (e. g. Amflora® potato, BASF SE, Germany).
As mentioned at the outset, in a preferred embodiment of the invention, the inventive mixtures are used for the protection of the seed and the seedlings' roots and shoots, preferably the seeds.
Seed treatment can be made into the seedbox before planting into the field.
For seed treatment purposes, the weight ration in the inventive mixtures generally depends from the properties of the compounds of the inventive mixtures.
Customary formulations, which are especially useful for seed treatment are e.g.:
A Soluble concentrates (SL, LS)
D Emulsions (EW, EO, ES)
E Suspensions (SC, OD, FS)
F Water-dispersible granules and water-soluble granules (WG, SG)
G Water-dispersible powders and water-soluble powders (WP, SP, WS)
H Gel-Formulations (GF)
I Dustable powders (DP, DS)
These compositions can be applied to plant propagation materials, particularly seeds, diluted or undiluted. These compositions can be applied to plant propagation materials, particularly seeds, diluted or undiluted. The compositions in question give, after two-to-tenfold dilution, active substance concentrations of from 0.01 to 60% by weight, preferably from 0.1 to 40% by weight, in the ready-to-use preparations. Application can be carried out before or during sowing.
Methods for applying the inventive mixture and compositions thereof, respectively, on to plant propagation material, especially seeds, are known in the art, and include but not limited to, seed dressing, seed coating, seed dusting, seed soaking, seed film coating, seed multilayer coating, seed encrusting, seed dripping, and seed pelleting.
In a preferred embodiment, the compounds or the compositions thereof, respectively, are applied on to the plant propagation material by a method such that germination is not induced, e. g. by seed dressing, pelleting, coating and dusting.
In the treatment of plant propagation material (preferably seed), the application rates of the inventive mixture are generally for the formulated product (which usually comprises from 10 to 750 g/l of the active(s)).
The invention also relates to the propagation products of plants, and especially the seed comprising, that is, coated with and/or containing, a mixture as defined above or a composition (customary formulation) comprising the inventive mixture of two or more active ingredients or a mixture of two or more compositions each providing one of the active ingredients. The plant propagation material (preferably seed) comprises the inventive mixtures in an amount of from 0.1 g to 10 kg per 100 kg of plant propagation material (preferably seed), preferably 0.1 g to 1 kg per 100 kg of plant propagation material (preferably seed).
The separate or joint application of the compounds of the inventive mixtures is carried out by spraying or dusting the seeds, the seedlings, the plants or the soils before or after sowing of the plants or before or after emergence of the plants.
In accordance with one variant of soil application, a further subject of the invention is in furrow treatment, which comprises adding a solid or liquid formulation comprising the inventive mixtures to the open furrow, in which seeds have been sown or, alternatively, applying seeds and formulation simultaneously to the open furrow.

In a preferred embodiment of the invention the mixture of the invention is used for controlling insects or arachnids, in particular insects of the orders Lepidoptera, Coleoptera, Thysanoptera and Homoptera and arachnids of the order Acarina. The mixture of the invention is particularly useful for controlling insects of the order Thysanoptera and Homoptera.
The mixtures of the present invention show synergistic action against the pests to be controlled. Synergism can be described as an interaction where the combined effect of a mixture of two or more compounds is greater than the sum of the individual effects of each of the compounds. The presence of a synergistic effect, in terms of percent control, between two mixing partners (X and Y) can be calculated using the Colby equation (Colby, S. R., 1967, Calculating Synergistic and Antagonistic Responses in Herbicide Combinations, Weeds, 15, 20-22):
In Colby's formula X and Y are the % control observed for the individual compounds at a given concentration. E is the expected combined control effect, which would be expected in the absence of synergism, if the compounds were applied together at the same concentrations of solo application. When the control effect observed for the mixture (i.e. the observed combined control effect) is greater than the expected combined control effect (E) as calculated from Colby's formula, then the observed effect is synergistic.
The expected efficacies of active compound mixtures were determined using Colby's formula [R. S. Colby, “Calculating synergistic and antagonistic responses of herbicide combinations”, Weeds 15, 20-22 (1967)] and compared with the observed efficacies.
Microtests
The active compounds were formulated separately as a stock solution having a concentration of 10000 ppm in dimethyl sulfoxide.
The compound of formula I was used as a commercial finished formulation and diluted with water to the stated concentration of the active compound.
The stock solutions were mixed according to the ratio, pipetted onto a micro titer plate (MTP) and diluted with water to the stated concentrations. A spore suspension of Phytophtora infestans containing a pea juice-based aqueous nutrient medium was then added. The plates were placed in a water vapor-saturated chamber at a temperature of 18° C. Using an absorption photometer, the MTPs were measured at 405 nm 7 days after the inoculation. The measured parameters were compared to the growth of the active compound-free control variant (100%) and the fungus-free and active compound-free blank value to determine the relative growth in % of the pathogens in the respective active compounds. These percentages were converted into efficacies. An efficacy of 0 means that the growth level of the pathogens corresponds to that of the untreated control; an efficacy of 100 means that the pathogens were not growing. The test results are shown in Table 1.
The stock solutions were mixed according to the ratio, pipetted onto a micro titer plate (MTP) and diluted with water to the stated concentrations. A spore suspension of Septoria tritici in an aqueous biomalt solution was then added. The plates were placed in a water vapor-saturated chamber at a temperature of 18° C. Using an absorption photometer, the MTPs were measured at 405 nm 7 days after the inoculation. The measured parameters were compared to the growth of the active compound-free control variant (100%) and the fungus-free and active compound-free blank value to determine the relative growth in % of the pathogens in the respective active compounds. These percentages were converted into efficacies. An efficacy of 0 means that the growth level of the pathogens corresponds to that of the untreated control; an efficacy of 100 means that the pathogens were not growing. The test results are shown in Table 2.
The stock solutions were mixed according to the ratio, pipetted onto a micro titer plate (MTP) and diluted with water to the stated concentrations. A spore suspension of Alternaria solani in an aqueous biomalt solution was then added. The plates were placed in a water vapor-saturated chamber at a temperature of 18° C. Using an absorption photometer, the MTPs were measured at 405 nm 7 days after the inoculation. The measured parameters were compared to the growth of the active compound-free control variant (100%) and the fungus-free and active compound-free blank value to determine the relative growth in % of the pathogens in the respective active compounds. These percentages were converted into efficacies. An efficacy of 0 means that the growth level of the pathogens corresponds to that of the untreated control; an efficacy of 100 means that the pathogens were not growing. The test results are shown in Table 3.
The test results show that by virtue of strong synergism, the activity of the mixtures according to the invention is considerably higher than had been predicted using Colby's formula.
