Abstract
Combinations of cyproconazole with flutriafol and combinations of either of these active ingredients with a sterol biosynthesis inhibitor belonging to the triazole family exhibit synergistic fungicidal activity against phytopathogenic fungi. Favorable biological properties are suggesting an application of these combinations for example in cereals. The sterol biosynthesis inhibitors include flutriafol, flusilazole, hexaconazole, triadimenol, propiconazole, epoxiconazole, fenbuconazole, tetraconazole, bromuconazole, diniconazole, difenoconazole and tebuconazole.
Description
FUNGICIDAL COMPOSITIONS The present invention relates to fungicidal compositions, more specifically to fungicidal compositions containing a first fungicidally active compound and a second fungicidally active compound, and a method of combatting phytopathogenic fungi.
All of the fungicidally active compounds contemplated by this application are known as sterol biosynthesis inhibitors belonging to the triazole family. They have, in the past, been used separately to combat various types of pathogenic fungi. It has now been found that certain combinations of such triazoles result in fungicidal compositions that demonstrate unexpected synergistic fungicidal activity.
The fungicidal composition of this invention, accordingly, is characterized in that it comprises a first fungicidally active compound (a) cyproconazole; and a second fungicidally active compound selected from the group consisting of (b) sterol biosynthesis inhibitors belonging to the triazole family selected from flutriafol, flusilazole, hexaconazole. triadimenol, propiconazole, epoxiconazole, fenbuconazole, tetraconazole, bromuconazole, diniconazole, difenoconazole and tebuconazole; or comprises a first fungicidally active compound (a) flutriafol; and a second fungicidally active compound selected from the group consisting of (b) sterol biosynthesis inhibitors belonging to the triazole family selected from flusilazole, hexaconazole, triadimenol, epoxiconazole, fenbuconazole, tetraconazole, bromuconazole, diniconazole, difenoconazole and tebuconazole; wherein components (a) and (b) are present in the composition in amounts producing a synergistic fungicidal effect.
Each of the members of triazole family of fungicides is known and commercially available. 70451 ' - 2 A preferred combination according to the invention is that of cyproconazole with a triazole selected from the aforementioned group b). Particularly preferred combinations are those of cyproconazole (/ with any one selected from the group comprising flutriafol, flusilazole, propiconazole, difenoconazole and fenbuconazole. Another L group of preferred combinations comprises flutriafol as component (a) and any one of the components (b) selected from the group comprising tetraconazole, tebuconazole and epoxiconazole. However, the most preferred combination is that of cyproconazole and flutriafol.
Fungicidal compositions according to the invention are effective in combatting a variety of fungi including Erysiphe graminis f. sp. hordei in barley, Erysiphe graminis f. sp. tritici in vheat, Cochliobolus sativus in barley, Septoria nodorum and Septoria tritici in vheat and barley, Puccinia striiforais and Puccinia recondita in vheat, Orechslera teres in barley, and Drechstera tritici -repent is in vheat.
The veight ratio of the first fungicidally active compound to the second fungicidally active compound in fungicidal compositions according to the invention will depend on various factors such as the particular active ingredient, the mode of application, the pathogenic fungi to be combatted, the crop, the application time, etc. In general, good results are obtained with compositions containing a veight ratio of component (a) to component (b) ranging from 1:1 to 1:4. Hore preferably, the veight ratio of component (a) to component (b) vill range from 1:1 to 1:2.
Suitable fungicidally effective aggregate amounts of the first and second fungicidally active compounds lie in the range of from 50 to 100 g/ha of crop locus. In general, satisfactory results vill be obtained vhen employing from 20 to 100 g/ha of the first fungicidally * active compound, more particularly 60 to 80 g/ha, and from 40 to 150 g/ha of the second fungicidally active compound. " * Though formulating the components of the combination into a single combined form and to utilize spray liquors prepared therefrom on cultivated areas is the preferred embodiment of present invention, it is also possible to apply the components separately or in form of a tank-mixture spray being prepared from separate concentrated forms of these components shortly before spraying.
The application rate may also be expressed in terms of concentrations. Spray liquors suitable for use in, for example, grapevines or cereals comprise from 50 to 250 g per hectoliter. The spray treatment involves usually foliar application until run-off. This corresponds in general with a spray volume of from 600 to 1000 liters per hectare of crop locus, depending upon type of crop, field conditions, etc.
Compositions according to the invention may be formulated in any conventional form, for example in the form of a twin pack, or of an emulsifiable concentrate, a soluble concentrate, a vettable powder or water dispersible granule. Such compostions can be formulated using adjuvents and formulation techniques that are known in the art for individually formulating the fungicidally active compounds, for example by mixing the first fungicidally active compound with the second fungicidally active compound together with diluents and optionally other formulating ingredients such as surfactants.
The term diluent as used herein means any liquid or solid agriculturally acceptable material - including carriers which may be added to the fungicidally active compounds to bring them in a suitable application or commercial form. Diluents include talc, kaolin, diatomaceous earth, mineral oil and water.
Formulations to be applied in spraying forms such as water dispersible concentrates or wettable powders may contain surfactants such as wetting and dispersing agents, e.g. the condensation product of formaldehyde with naphthalene sulponate, an alkylarylsulphonate, a lignin sulphonate, a fatty sulphate, an ethoxylated alkylphenol and an ethoxylated fatty alcohol.

Fungicidal testing The efficiency of the mixture according to the invention in controlling various pathogenic fungi is demonstrated using the folloving procedure.
In vivo tests: Erysiphe graminis in wheat or barley Wheat or barley is cultivated for 8-10 days in a mixture of peat and sand in plastic pots of 6 cm diameter. The plants are spray treated with aqueous spray liquors containing a compound A, a compound B or mixtures thereof (hereinafter a.i.) in various concentrations. The treatment comprises foliar spraying to near runoff. After drying (24h), the plants are inoculated in a settling tover vith dry spores of Erysiphe graminis and are then incubated for 7 days in a growth chamber at 60-80Z relative humidity, 16 hours daylight and 20°C. The efficacy of the a.i. is determined by comparing the degree of fungal attack on the treated plants with that on untreated, similarly inoculated and incubated check plants. Each a.i. is tested in 4 to 5 concentrations. This allows for the determination of the experimental EC 90 value (EC 90 exp.), i.e. the concentration of each a.i. providing 90Z disease control.
Analogous tests are run with Septoria nodorum on wheat. In these tests, the inoculation of the plants is done by spray application of a spore suspension containing 1 x 10s spores/ml.
Activity of the a.i. against Puccinia striiformis or Puccinia recondita on wheat is tested analogously, but on detached leaves. Wheat plants are cultivated and spray treated in accordance vith the above mentioned methods. After drying, the primary leaves of the plants are detached, inoculated in a spore-settling tover and incubated on water agar for 20 days at 10°C.
In vitro tests: Activity of the a.i. against Septoria tritici, Septoria nodorum, Drechslera teres and Drechslera tritici-repentis is tested in vitro. Potato dextrose agar medium (PDA) is prepared and cooled to 55*C. Quantities of fungicide solutions in water are added to give the following concentrations in the agar medium: 0.01, 0.1, 1, 10 and 100 ppm a.i. Agar plugs are cut from the edge of growing colonies of the fungi to be tested using a cork borer. These plugs are placed on the fungicide-amended agar media. The radial mycelial growth is measured after incubation for 7 days at 20°C in the dark and compared to the growth on PDA without fungicides. The EC 90 exp. value is calculated.
Calculation of synergistic effects: The experimental result (EC 90 exp.) for a given veight ratio of Compound A : Compound B is compared with the corresponding EC 90 theor. value, i.e. the concentration of that particular mixture alloving 90Z disease control calculated according to Badley: a + b EC (A+B) 90 theor. « _ _a + b_ EC(A)90 exp. EC(B)90 exp. wherein a and b are the ratios of Compund A and Compound B in the mixture and the indexes (A) (B) and (A+B) refer to the EC 90 values of Compound A, Compound B and the a:b mixture of Compound A and Compound B, respectively. In case of synergism EC(A+B)90 theor. is greater than EC(A+B)90 exp., or EC(A+B)90 theor.
Synergy-factor (SF) = _· > 1.
EC(A+C)90 exp.
According to these tests, the mixtures of the invention shov an activity which is markedly superior to the sum of the activity of each of the active agents vhen taken individually.
