Description

[0001] The present invention relates to a fungicidal active compound composition for turf treatment,

The present invention relates to a novel composition comprising a fungicide (QoI inhibitor) inhibiting mitochondrial respiration at the QoI site, a contact fungicide, a demethylation inhibitor and a pigment, and more particularly to a novel composition comprising an undesirable phytopathogenic fungus ) ≪ / RTI > In addition, the fungicidal composition can prevent the infection of molds and fungi of grasses, especially turf grass.

The luxurious Turfgrass species grow on the green of golf courses, fairways, teaboxes, as well as turf farms and elsewhere. In the late summer and early autumn temperatures and in North America such as Canada and North America with late winter and early winter snow conditions, dollar spots, molds such as Sclerotinia homeocarpa , ballet (Microdochium nivale), Thailand Description bubyeong (snow mold), such as Pula Incar appear (Typhula incarnata) and Thai Pula Ishikari N-Sys (Typhula ishikariensis) is a chronic problem of grass Turf growers.

If left untreated in late summer and autumn, the toughgrass is prone to be damaged by sprains in late summer and fall, and in spring and late fall and winter in spring. Sclerotinia Homo Carpara attacks most of the Turfgrass growing in the south. Bent grass, plain and hybrid bermudagrass and zoysia are very sensitive to the attack of Sclerotinia hommiocca. Dollar spot disease occurs from spring to autumn and is most active during wet periods of warm weather (about 70 ° F to about 85 ° F) and cold nights of spring, early summer and autumn (about 60 ° F).

If the fungal infection is severe, the recovery of the toughgrass may be delayed by the growing period, which may seriously affect the ability of the toughgrass to recover, leaving a dead spot area. In addition, turbofacies weakened or damaged by this fungus are very slow to recover in the spring, and are unfavorably opportunistic, such as creeping bent grass ( Agrostis palustris ) and annual bluegrass ( Poa annua ) ) It is invaded by weed grass.

Typical anti-spoilage programs require a fungicide-fungicide to be applied to tough grass prior to continuous winter snowfall. Typical programs consist of three applications before the continuous snowfall and additional application after the snowfall disappears in the spring. Several commercially available fungicide products have been approved for use in dollar spot and snowy disease.

COMPASS 占 (trifloxystrobin; (? E) -? (Methoxyimino) -2 - [[[(E) - [1- [3- (trifluoromethylphenyl) ethylidene] ] Methyl] benzene acetic acid methyl ester) is an aromatic dioxime fungicide approved for the control of leaf spot, Fusarium patch and brown patch disease in Turfgrass. Robin is a quinone outside inhibitor (QoI) and belongs to the aromatic dioxin fungicides described in U.S. Patent No. 5,238,956.

ROVRAL GREEN ™ GT (child Pro-dione (iprodione); 3- (3,5- dichlorophenyl) - N - (1- methylethyl) -2,4-dioxo-1-imidazolidine carboxylic imide) 250 Ml / 100 m < 2 > for the control of pink louse disease, and a dicarboxylic fungicide for the control of gray louse disease at a rate of 375 ml / 100 m < Ioprodione is a class of 3-phenylhydantoin compounds described in U.S. Patent No. 3,755,350.

The efficacy of isoprodion to control the spread of snowdrop (especially T. incarnata and T. ishikariensis ) in turfgrass depends on the diverse depths of snowfall in which various amounts of fungal inocula, It is highly variable due to the various winter temperatures that exist throughout the country. Accordingly, in order to efficiently control various snowy diseases, a relatively high dosage as well as several applications may be required.

Phthalocyanine is a known pigment having various uses such as a pigment for ink and coating agent and a pigment for toughgrass paint. For example, DE 2,511,077 and JP 03/221576 can be referred to. Copper phthalocyanine is used or is only used with other active ingredients to enhance tough quality. For example, U.S. Pat. No. 5,599,804 discloses that phthalocyanine may be used in combination with phosphorous acid or alkaline earth metal salts thereof or a monoester salt of phosphorous acid in a certain ratio to prevent fungi and to enhance tough properties in the toughgrass . U.S. Patent No. 5,643,852 teaches that tough characteristics can be achieved in tuftgrass by using phthalocyanine in certain proportions with (i) a phosphorous acid or its alkaline earth metal salt or monoester salt of phosphorous acid, and (ii) ethylene bisdithiocarbamate contact fungicides, And the like. U.S. Patent No. 5,336,661 describes a method of treating bentgrass using a monoester salt of phosphorous acid and (ii) a metallic ethylene bisdithiocarbamate contact fungicide at a specified ratio to enhance tough quality. This patent also discloses the use of manganese-zinc ethylene bisdithiocyanate as a form (FORE fungicide) which appears to contain an unknown amount of aluminum tris ( O -ethylphosphonate) (porcelanyl-phthalocyanine) and phthalocyanine compound Pigment Blue 15 Carbamate < / RTI > complexes (mancozeb).

Here, the efficacy is determined in%. 0% means the efficacy corresponding to the control, whereas 100% efficacy means no infection.

If the actual fungicidal activity is greater than calculated, the activity of the combination is superadditive, that is, synergistic. In this case, the actual observed efficacy should be much greater than the value for the expected efficacy E ₁ calculated in the above equation.

Hereinafter, the present invention will be described in detail by way of examples (although the present invention is not limited by the examples).

Example

QoI Inhibitors The excellence of various compositions including fungicides, contact fungicides, demethylation inhibitors and pigments was tested in the following places to measure for compositions containing three fungicides and no pigment: 1. University of Massachusetts, Vermont; 2. University of Wisconsin, Sentry; 3. University of Wisconsin, Iron Mountain; 4. University of Wisconsin, Champion Ml; 5. University of Wisconsin, Edina MN; 6. Oregon State University, Sun River; 7. Washington State University, McCall; 8. Washington State University, Chewelah; And 9. Pullman, Washington State University.

The general method of applying the described composition is as follows: The treatment plot is, for example, 6 feet x 7 (3.8 square meters) feet and repeated three times in a fully randomized fashion. The treatment was applied from late October to mid November. In some instances, the composition was applied with a bicycle-wheeled CO ₂ pressurized (40 psi = 2.8 bar) atomizer with 11008 platform fan TeeJet nozzles at 80 GPA.

Some places have intermittent snow during the winter, and there is a continuous snowing period. If the snow was melted or mechanically removed, the individual plots were evaluated for the degree of M. nivale and / or Typhula spp. (Infected area%) and the Turfgrass quality (grade 1 to 9, grade 9 Rating).

Table 1 shows compositions containing different amounts of a QoI inhibitor fungicide (triflocystrobin), a contact fungicide (iprodione), and a demethylation inhibitor (triticonazole) and a pigment (phthalocyanine green pigment) (TQ) or tough color (TC) in comparison with a standard blend of three fungicides (INSTRATA ^® , manufactured by SYNGENTA) blended with non-fungal antifungal agents. The rating is 1 to 9, 1 = poor and 9 = excellent. INSTRATA ^® , a tall, disease - free product containing three fungicides and no pigment was used as a control.

^a Location: 1. University of Massachusetts, Vermont; 2. University of Wisconsin, Sentry; 3. University of Wisconsin, Iron Mountain; 4. University of Wisconsin, Champion Ml; 5. University of Wisconsin, Edina MN; 6. Oregon State University, Sun River; 7. Washington State University, McCall; 8. Washington State University, Chewelah; And 9. Pullman, Washington State University.

^b A = triplexistrobin; B = isopropylidene; C = phthalocyanine green pigment (Green 7); D = Triticonazole (3 lb ai / gal = 358 g / L)

^c INSTRATA ^® = commercial non-pigmented standard (propiconazole + fluodioxinyl + chlorotallonyl)

^d Pink Southerly Place

^e (A + B + C): 123 g / 100 m ²

^f (A + B + C): 151 g / 100 m ²

Compositions comprising a A + B + C + D is INSTRATA ^® + pigments and equivalents thereof. In other words, it is possible to demonstrate the excellent effect of a composition comprising three kinds of fungicides and pigments for a composition containing only three kinds of fungicides (i.e., containing no pigment) by direct comparison using such a composition . These results indicate that TQ and TC are superior to INSTRATA ^® at all locations using a composition containing a dye and three fungicides. This means that tough is better restored and better looking with INSTRATA ^® using a composition that includes pigment and three fungicides.

The results at Site 9, a composition comprising two fungicides (A + B) and C, indicate that at least INSTRATA ^® is better if the compositions of the two fungicides and pigments are slightly better. This is surprising because INSTRATA ^® contains three fungicides (no pigment). In other words, similar effects to the use of three fungicides can be obtained using two fungicides and pigments.

Table 2 shows compositions which contain different amounts of QoI inhibitor fungicide (triflocystrobin), contact fungicide (isoprodione), demethylation inhibitor (triticonazole) and pigment (phthalocyanine green pigment) as compared to INSTRATA ^® The effect of the disease prevalence rate on the location of the disease.

^d Pink Southerly Place

^e (A + B + C): 123 g / 100 m ²

^f (A + B + C): 151 g / 100 m ²

The results in Table 2 indicate that the composition containing the pigment and the three fungicides healed the infectious disease to the same extent as INSTRATA ^® . In other words, the compositions described are as effective as INSTRATA ^® in killing mold. A good advantage of compositions that additionally contain pigments such as phthalocyanine is that after winter, good recovery of tough during spring green up; Good state of tough; And good aesthetics (visually excellent toughness).

QoI inhibitors fungicides, contact fungicides, demethylation inhibitors; And pigments can be present in the composition at any ratio. Examples of suitable ratios are shown in Table 3.

The amount of ^g contact fungicide is kept constant as a standard.

Other exemplary compositions of triflocystrobin, isoprothionine, and phthalocyanine green dyes are shown in Table 4, which were suspended in water.

Table 5 with respect to the commercially available solution of INSTRATA ^®, 1.47 g / L triple hydroxy host Robin, the phthalocyanine of 29.41 g / L child Pro-dione, 3.14 g / L tree Tycho najol, and 6 g / L of the ≪ / RTI > The four component composition and INSTRATA ^® were applied to the Bentgrass / Poa float at the Westmount Golf & Country Club in Kitchener, Ontario, Canada.

As can be seen from the results, the use of a four component composition of triplexistrobin, ipprodione, triticonazole and phthalocyanine was superior to INSTRATA ^® . The four component composition was 0% to 2%, providing better disease control than INSTRATA ^® (measured by infected area percentages), as well as better TQ of 8.7 to 9 vs. 6.6. In addition, excellent results can be obtained using INSTRATA ^® (300 mL / m ² ) versus a fairly small amount of composition (100 mL / 100 m ² to 177.5 mL / m ² ). This is meaningful not only from an environmental point of view that chemicals are rarely used in the soil but also from a low cost economic point of view.

Without wishing to be bound by theory, it can be seen that a variety of fungicides act synergistically with the pigment and that a superior effect can be observed.

Other tests were conducted in Europe and the results are shown below.

The test was designed to study the efficacy and efficacy of tough quality combinations of two active ingredients (trioctostrobin, the QoI inhibitor fungicide and ioprodion, a contact disinfectant) and a dye (phthalocyanin). The fungicide compounds were individually applied at two different concentrations in blends containing the (pigmentless) and pigment (s). These treatments were compared with commercial standard products.

It was tested in various locations in England and Germany in 2008, from late July to early December, depending on the disease. The test was designed with four iterations and a plot area of 4 to 6.25 m ² in a fully randomized manner. The product was applied in a water volume of 400-500 L per hectare by spray application. In application, it was operated at 2.2 to 3.0 bar using an air pressure spray with TeeJet or a faltfan nozzle. And was applied twice at intervals of 28 days.

The test was evaluated at intervals of 14 to 28 days after the first application up to a maximum of 72 days. Tough Disease: Microdochium nivale , rust ( Puccinia spp ), and red tread ( Laetisaria fuciformis ) were assessed as percentage of infected canopy per plot. The tough quality (color and / or density) was determined to be a general grade. The data were expressed as an average for the total evaluation.

Table 6 shows compositions containing different amounts of a QoI inhibitor fungicide (triflocystrobin), contact fungicide (isoprodione) and a dye (phthalocyanine green dye) and a composition containing no pigment in a commercial standard (DACONIL and AMISTAR, both (TQ) and / or tough color (TC) in comparison to the tough color (TQ) and / or tough color (TC). Data are shown in grades 1 through 9, with 1 = poor and 9 = excellent.

^a Location: 1. Lothian, England; 2. Middletown, England; 3. Germany, South; 4. United Kingdom, Essex (Essex)

A = triplexistrobin; B = isopropylidene; C = phthalocyanine green pigment (Green 7)

^b DACONIL ^® = commercial standard that does not contain pigments (chlorotallonyl)

^c AMISTAR ^® = commercial standard that does not contain pigments (azithromycin)

The data in Table 6 show the improvement in tough quality in the plots in which compounds A and B are compounded with compound C. Treatment with only compounds A and B and treatment with compound A + B showed a lower quality grade than A + B + C. This result is supported by the results for the commercial standard, the commercial standard does not contain the compound C and it also got a lower rating.

Table 7 shows that compared to DACONIL ^® or AMISTAR ^® , the disease spreads according to the location of compositions containing different amounts of QoI inhibitor fungicide (triflocystrobin), contact fungicide (isoprodion) and pigment (phthalocyanine green pigment) The effect on the rate is shown.

The data in Table 7 show that the combination of compound A + B + C is better in controlling the tough pathogen Puccinia spp. Than the compound A + B alone (without dye C). This effect was confirmed from the fact that the combination of compound A + B + C surpasses blend A + B even at reduced ai concentrations.
