METHOD FOR CONTROLLING PHYTOPATHOGENIC ORGANISMS

FIELD OF THE INVENTION

The present invention is directed to methods of protecting crops of useful plants against attack by phytopathogenic organisms as well as the treatment of crops of useful plants infested by phytopathogenic organisms comprising administering a combination of glyphosate and at least one fungicide to the plant or locus thereof.

BACKGROUND OF THE INVENTION

Crop yield can be adversely affected by disease. The use of fungicides to control disease and/or reduce the effects of disease on crops is an important part of modern agricultural practice. Diseases such as those of the order Uredinales, also referred to as rusts, can be particularly damaging to crops such as cereals, cotton and soybeans. The Uredinales have long attracted considerable interest in agriculture, horticulture and forestry, as they are parasites which have great economic impact.

It is known that certain fungicides have activity on at least some of the diseases of the order Uredinales and can be used for the control of rusts in crops of useful plants.

Glyphosate is the largest selling agrochemical in the global market. It finds uses for control of unwanted vegetation in virtually every agricultural production system, as well as in forestry, industrial, municipal, residential, rights-of-way, amenity and other applications. Glyphosate is an acid that is relatively insoluble in water. For this reason it is typically formulated as a water- soluble salt in aqueous solution. While there have been mixed reports regarding the fungicidal activity of glyphosate, the post-emergent application of glyphosate for controlling weeds in crops of glyphosate resistant plants is known.

SUMMARY OF THE INVENTION

The present invention is directed to methods of protecting crops of useful plants against attack by phytopathogenic organisms as well as the treatment of crops of useful plants infested by

phytopathogenic organisms comprising administering a combination of glyphosate and at least one fungicide to the plant or locus thereof, wherein the plant is resistant or sensitive to glyphosate.

The methods of the present invention provide unexpectedly improved control of diseases compared to using the fungicide in the absence of glyphosate. The methods of the present invention are effective at enhancing the fungicide's control of disease. While the mixture of glyphosate and at least one fungicide may increase the disease spectrum controlled, at least in part, by the fungicide, an increase in the activity of the fungicide on disease species already known to be controlled to some degree by the fungicide is the effect most often observed.

The methods of the present invention are particularly effective against the phytopathogenic organisms of the kingdom Fungi, phylum Basidiomycota _s class Uredinomycetes, subclass Urediniomycetidae and the order Uredinales (commonly referred to as rusts). Species of rusts having a particularly large impact on agriculture include those of the family Phakopsoraceae, particularly those of the genus Phakopsora, for example Phakopsora pachyrhizi, which is also referred to as Asian soybean rust, and those of the family Pucciniaceae, particularly those of the genus Puccinia such as Puccinia graminis, also known as stem rust or black rust, which is a problem disease in cereal crops and Puccinia recondita, also known as brown rust.

An embodiment of the present invention is directed to a method of protecting crops of useful plants against attack by a phytopathogenic organism and/or the treatment of crops of useful plants infested by a phytopathogenic organism, said method comprising simultaneously applying glyphosate, including salts or esters thereof, and at least one fungicide having activity against the phytopathogenic organism to at least one member selected from the group consisting of the plant, a part of the plant and the locus of the plant, whereby the application of glyphosate and the at least one fungicide results in protection of said crops from phytopathogenic organisms and/or control and/or inhibition of infection of said crops resulting from the infestation of the phytopathogenic organisms.

One embodiment of the present invention is directed to a method of protecting crops of useful plants against attack by a phytopathogenic organism of the order Uredinales and/or the treatment of crops of useful plants infested by a phytopathogenic organism of the order Uredinales,

said method comprising simultaneously applying glyphosate, including salts or esters thereof, and at least one fungicide having activity against phytopathogenic organisms of the order Uredinales to at least one member selected from the group consisting of the plant, a part of the plant and the locus of the plant.

The methods of the present invention result in unexpectedly improved fungicidal activity against phytopathogenic organisms compared to the activity obtained by using the fungicide alone.

DETAILED DESCRIPTION OF THE INVENTION

Glyphosate is typically used in form of its monobasic, dibasic or tribasic salts. Dibasic salts, such as the diammonium salt, of glyphosate are useful in compositions of the invention, but monobasic salts are generally preferred. Of these, particularly preferred examples include the monosodium, monopotassium, monoammonium, mono(dimethylammonium), mono(ethanolammonium), mono(isopropylammonium) and mono(trimethylsulfonium) salts as well as mixtures thereof.

While one or more treatments with glyphosate can be used within the scope of the present invention, the rate of glyphosate applied in combination with the fungicide(s) will depend on the sensitivity of the plant to glyphosate and whether weed control is an objective in addition to the enhancement of the fungicidal activity. Enhanced fungicidal activity against the target pathogens can be obtained by applying mixtures of glyphosate and fungicides at levels of glyphosate having low phytotoxicity against the treated plant, including glyphosate sensitive plants, i.e., plants which may exhibit unacceptable levels of damage when exposed to rates of glyphosate typically used for weed control. When it is said that the glyphosate has low phytotoxicity, it is meant that the amount of the glyphosate used is insufficient to cause damage to the plant at levels that counterbalance or overwhelm the beneficial activity of the active agent. It is more preferred that the glyphosate, when applied, causes damage that is commercially insignificant. It is even more preferred that the glyphosate, when applied, causes no measurable damage. For weed control, the amount of glyphosate required will depend on a number of factors including co-herbicides present, crop tolerance, weed type, level of weed pressure,

-A- climatic conditions and the like. Rates up to the maximum total in-crop amount permitted by any applicable label can be used.

The plant and plant propagation material useful in the present invention can be a plant sensitive to levels of glyphosate conventionally used for weed control or glyphosate resistant plants made tolerant to glyphosate by conventional breeding or having a transgenic event that provides glyphosate resistance. Some examples of such preferred transgenic plants having transgenic events that confer glyphosate resistance are described in U.S. Pat. Nos. 6,040,497; 5,914,451; 5,866,775; 5,804,425; 5,776,760; 5,633,435; 5,627,061 ; 5,463,175; 5,312,910; 5,310,667; 5,188,642; 5,145,783; 5,094,945; 4,971,908; 4,940,835 and 4,535,060, all of which are incorporated by reference in their entirety. The use of "stacked" transgenic events in the plant is also contemplated.

Stacked transgenic events including additional herbicide-resistant traits such as resistance to HPPD-inhibitors, glufosinate and bromoxynil are widely used and described in readily available resources.

Genetically modified cotton plants also include those which express toxins from Bacillus thuringiensis (Bt) and which are consequently resistant to attack by certain harmful insects are known and are increasingly employed in commercial agriculture (see, for example, US Patent No. 5,322,938).

Any fungicide suitable for post-emergent application to the plant may be used in the methods of the present invention. It is preferred that the fungicide has low phytotoxicity against the plant that is treated. When it is said that the fungicide has low phytotoxicity, it is meant that the amount of the fungicide used is insufficient to cause damage to the plant at levels that counterbalance or overwhelm the beneficial activity of the active agent. It is more preferred that the fungicide, when applied in an efficacious amount, causes damage that is insignificant. It is even more preferred that the fungicide, when applied in an efficacious amount, causes no measurable damage.

In one embodiment, fungicides that are particularly suitable for use in the present invention include those that have demonstrated activity against phytopathogenic organisms of the order

Uredinales.

While one or more treatments with fungicides can be used within the scope of the present invention, the amount of fungicide used and timing of application will vary based on numerous factors including the fungicide selected, region, climate, target disease, level of actual or expected disease pressure and crop and can readily be determined by one of ordinary skill. Each fungicide has a unique preharvest interval indicated on the product label. For control late in the season, one should ascertain the products preharvest interval before making an application. Combinations of a protectant fungicide and an early curative fungicide may be used and are effective against spore germination, host penetration and tissue colonization. Combinations of fungicides having different modes of action are also preferred in order to reduce the risk of fungicide resistance. In one embodiment of the present invention, at least one fungicide is applied to the plant, a part of the plant and/or the locus of the plant before and/or after the application of glyphosate and at least one fungicide. In one embodiment of the present invention, at least one fungicide is applied to the plant propagation material before the application of glyphosate and at least one fungicide.

In the case of soybeans, for example, glyphosate may be applied anytime from cracking through flowering up to the preharvest interval. The fungicides for controlling rust, for example, are preferably applied during the vegetative stage and from the beginning of flowering (Rl) through full seed (R6).

The fungicides that are useful in the present invention can be used in any purity that passes for such fungicide in the commercial trade. The fungicide can be used in any form in which it is received from the supplier, or in which it is synthesized. It is preferred that the fungicide be supplied in the form of a liquid, which form includes, without limitations, solutions, suspensions and dispersions. However, the liquid can be a substantially pure form of the fungicide, or it can be the fungicide dissolved in a solvent. Commonly, if a solvent is present, such solvents are organic liquid solvents that are commonly used in such applications. If the fungicide is water soluble, then water can be used as the solvent.

Plants to be treated by the subject method can be treated with one or more forms of the useful active ingredients without any additional materials being present. However, in some cases, it is

preferred to use the one or more active ingredients in combination with other materials in a composition.

Compositions of the present invention comprise an effective amount of one or more of the active ingredients described above and one or more adjuvants. If desirable, such compositions can also include such other materials as herbicides, insecticides, nematicides, acaricides, additional fungicides, fertilizers, and any other material that will provide a desirable feature for protecting, sprouting and. growing the plant. The choice of such other materials will depend on the crop and the pests known or thought to be a threat to that crop in the location of interest.

The compositions according to the invention are suitable for protecting crops of useful plants sensitive or resistant to glyphosate against attack by phytopathogenic organisms and/or the treatment of crops of useful plants sensitive or resistant to glyphosate infested by phytopathogenic organisms.

As used herein, the term "fungicide" shall mean a material that kills or materially inhibits the growth, proliferation, division, reproduction, or spread of fungi including, but not limited to, allergenic, toxinogenic and immunogenic fungi. As used herein, the term "prophylactic or fungicidally effective amount" or "amount effective to control or reduce fungi" in relation to the fungicidal compound is that amount that will kill or materially inhibit the growth, proliferation, division, reproduction, or spread of a significant number of fungi such as molds and, in particular, allergenic, toxinogenic or immunogenic varieties thereof in a target textile substrate

Selection of the fungicide(s) will depend upon the target phytopathogenic organisms. In an embodiment of the present invention, the efficacy of the selected fungicide(s) is increased by the addition of glyphosate to the composition. Representative classes of phytopathogenic fungi include: Fungi imperfecti (e.g. Botrytis spp., Alternaria spp.) and Basidiomycetes (e.g. Rhizoctonia spp., Hemileia spp., Puccinia spp., Phakopsora spp., Ustilago spp., Tilletia spp.). Additionally, the compositions of the invention are also effective against Ascomycetes (e.g. Venturia spp., Blumeria spp., Podosphaera leucotricha, Monilinia spp., Fusarium spp.,

Uncinula spp., Mycosphaerella spp., Pyrenophora spp., Rhynchosporium secalis, Magnaporthe spp., Colletotrichum spp., Gaeumannomyces graminis, Tapesia spp., Ramularia spp., Microdochium nivale, Sclerotinia spp.) and Oomycetes (e.g. Phytophthora spp., Pythium spp.,

Plasmopara spp., Pseudoperonospora cubensis). Furthermore, the the compositions of the invention are effective against phytopathogenic bacteria and viruses (e.g. against Xanthomonas spp, Pseudomonas spp, Erwinia amylovora as well as against the tobacco mosaic virus).

In one embodiment, the compositions according to the invention are suitable especially for protecting crops of useful plants against attack by a phytopathogenic organism of the order Uredinales and/or the treatment of crops of useful plants infested by a phytopathogenic organism of the order Uredinales.

The following examples illustrate further some of the aspects of the invention but are not intended to limit its scope. Where not otherwise specified throughout this specification and claims, percentages are by weight.

EXAMPLES

A synergistic effect exists whenever the action of an active ingredient combination is greater than the action expected from the effect of the individual components.

The action to be expected (E) for a given active ingredient combination obeys the so-called COLBY formula and can be calculated as follows (COLBY, S. R. "Calculating synergistic and antagonistic responses of herbicide combination". Weeds, Vol. 15, pages 20-22; 1967):

ppm=milligrams of active ingredient (=a.i.) per litre of spray mixture

X=% action by active ingredient I using p ppm of active ingredient

Y=% action by active ingredient II using q ppm of active ingredient.

According to Colby, the expected (additive) action of active ingredients I+II using p+q ppm of

X Y active ingredient is E = X + Y -

100

If the action actually observed (O) is greater than the expected action (E), then the action of the combination is superadditive, i.e. there is a synergistic effect.
