The invention relates to methods and compositions for stimulating plant growth. In particular, the invention relates to the use of ipfencarbazone, known as a pre-emergent herbicide, for stimulating or promoting plant growth.
Plant growth stimulators are used in many crops to increase biomass, manage the rate of growth and to increase yield and quality. These products are also used to manage abiotic stresses such as cold stress, drought stress, and the like.
In some aspects, embodiments herein provide methods of stimulating or promoting plant growth comprising applying to a crop plant a composition comprising ipfencarbazone in an amount sufficient to stimulate or promote plant growth.
Various embodiments of the invention will be described herein below with reference to the figures wherein:
Ipfencarbazone is classified as a tetrazolinone compound with a mode of action characterized by impacting cell division in the plant via inhibition of very long chain fatty acids (VLCFA's). Other classes of compounds that share this activity include acetamides, chloracetamides, and oxyacetamides.
Ipfencarbazone is safe for use on monocotyledonous crops including rice, corn, sorghum, millet, wheat, barley, oats, rye and triticale. As disclosed herein, at a range of rates there was a significant visible effect that suggested stimulation of a range of both monocotyledon and dicotyledon based crops, including corn, wheat, triticale, soybeans, dry beans, cotton, and the like.
Embodiments herein relate to the use of ipfencarbazone as a biostimulant (or plant growth regulator) for inter alia corn, wheat, soybeans, dry beans, cotton and pasture grasses when applied to the crop at specified application rates. This effect is particularly pronounced when applied post-emergence. Thus, certain application rates of ipfencarbazone, applied post emergent to a crop, demonstrated a significant increase in growth rate including, for example, biomass, leaf area, and plant height across a range of crop types.
As used herein, “plant” embraces plant crops (or just crops), ornamentals, trees, grasses, annuals, perennials or any other commonly cultivated member of the kingdom Plantae.
The application rate addition of ipfencarbazone may bolster the initial growth of seeds and/or crop seedlings, with the potential of masking phytotoxic effects of other agents when used in combinations and improve the initial plant stand. Other effects may include better plant health and more uniform stand through, for example, decreased seedling loss.
In particular embodiments, low application rates of ipfencarbazone, such as about 60 to about 125 grams per hectare, of ipfencarbazone demonstrated a positive effect on crop plants such as corn, wheat, soybean and dry bean seedlings, stimulating growth. Increased biomass, leaf area and rate of growth of crop plants were also observed. The methods herein may complement the spectrum of weed control and may be combined with other biostimulants/plant growth regulators (seed treatment) in a starter kit. These and other advantages will be apparent to those skilled in the art.
In some embodiments, there are provided methods comprising applying to a crop plant a composition comprising ipfencarbazone in an amount sufficient to stimulate plant growth. The term “crop plant(s)” as used herein, includes any edible or non-edible plant, including decorative, plant species with commercial value, which is planted and cultivated for commercial use. Thus, crop plants include floral and non-floral plants, perennials and annuals, trees, shrubs, vegetable plants, fruit trees, turf, and ground cover. Non-limiting specific examples of crop plants include canola, flax, peas, lentils, beans, linola, mustard, chickpeas, sunflowers, potatoes, seedling alfalfa, onions, soybeans and turf grass. The term “plants” is meant to include germinant seeds, cuttings, emerging seedlings, and established vegetation, including roots and above-ground portions, for example, leaves, stalks, flowers, fruits, branches, limbs, root, and the like.
The term “turf” used herein refers to grass which grow in areas in which they are desired, or purposely planned for and maintained, for example, a lawn. Turf also refers to a sod, where the surface layer of ground consisting of a mat of grass and grass roots.
The term “an amount of sufficient to stimulate or promote plant growth” means any amount of ipfencarbazone capable of increasing seedling germination, plant height, biomass, enhancing color, and the like, relative to an untreated control. In general, the amount sufficient to stimulate plant growth may be within the application rate range of from about 1 to about 1,000 grams of ipfencarbazone (active ingredient, a.i.) per hectare (ha). Optimal application rates for enhancing/stimulating plant growth may depend on a given crop plant and the ideal application rate range may comprise any sub-range from about 1 to about 1,000 grams ipfencarbazone per hectare, such as from about 50 to about 125 g a.i./ha, or 60 to 250 g a.i./ha, including any smaller or larger sub-ranges thereof, such as about 1 to about 60 g a.i./ha or about 250 to about 1,000 g a.i./ha.
In some embodiments, the amount sufficient to stimulate plant growth is in a range from about 20 grams per hectare to about 1,000 grams per hectare. In some embodiments, the amount sufficient to stimulate or promote plant growth is in a range from about 50 grams per hectare to about 250 grams per hectare. In some embodiments, the amount sufficient to stimulate plant growth is in a range from about 60 grams per hectare to about 125 grams per hectare, or about 1 gram per hectare to about 60 grams per hectare. As indicated in the Examples below and in the Figures, the particular applications rates that may be useful are readily determined based on a particular target crop.
In some embodiments, stimulating or promoting plant growth is assessed by enhanced seedling germination, plant height, leaf area, biomass, plant vigor, plant color, or combinations thereof. One or more of these characteristics can be measured by conventional means. Others may be assessed by visual observation.
In some embodiments, enhanced plant height is an increase in height from about 105 percent to about 400 percent of the control. In some embodiments, enhanced plant height is an increase in height from about 120 percent to about 350 percent of the control. As demonstrated in the Examples herein below, a series of application rates for a particular target crop plant can be used to determine a particular optimal application rate for a given plant, the optimal increase in characteristics being different depending on the exact crop plant.
In some embodiments, the applying step is carried out post-emergence. In some embodiments, post-emergence comprises seedling stage of the crop plant. In some embodiments, the applying step is carried out pre-emergence. In some embodiments, application of the compositions disclosed herein may be performed both pre- and post-emergence. In some embodiments, the applying step can be applied at any growth stage, including but not limited to, pre-emergence, early post emergence, and later stages of a crop growth cycle.
In some embodiments, compositions herein may be applied to perennial crops, including, without limitation, Stone fruits (cherries, plums, apricots, peaches, nectarines), blueberries, mangos, avocados, pastures, turfgrass, ornamentals, tree crops, eucalyptus, pine, tea, coffee, nut trees, citrus, tropical fruits, pome fruits, grapes and vines, perennial grasses, caneberries, bananas, sugarcane.

In further particular embodiments, the non-ionic surfactant is selected from the group consisting of ethoxylated fatty acids, alcohol ethoxylates, tristyrylphenol ethoxylates, ethoxylated sorbitan fatty acid esters or mixtures thereof. A surfactant may increase solubility of an active ingredient in a solution. A surfactant may also affect spray retention, droplet spreading, and dry rates. A surfactant may be anionic, cationic, non-ionic or amphoteric. Examples of anionic surfactants include phosphoric mono- and di-esters of long-chain alcohols having 14 to 22 carbon atoms and the salts thereof; phosphoric mono- and di-esters of alkylene oxide addition products of long-chain alcohols having 14 to 22 carbon atoms and the salts thereof; alkylsulfates having 14 to 22 carbon atoms; polyoxyethylene alkyl ether sulfates of alcohols having 14 to 22 carbon atoms; alkane sulfonates having 14 to 22 carbon atoms; and olefin sulfonates having 14 to 22 carbon atoms.
Suitable non-ionic surfactants include, for example, ethoxylated fatty acids, alcohol ethoxylates, tristyrylphenol ethoxylates, ethoxylated sorbitan fatty acid esters or mixtures thereof. Ethoxylated fatty acids include castor or canola oil ethoxylates having at least 25, or about 27 to 37 ethoxy units, such as Sunaptol CA350 (castor oil ethoxylate with 35 ethoxy units) of Uniqema (formerly ICI Surfactants), Mergital EL33 (castor oil ethoxylate with 33 ethoxy units) of Henkel KGaA, Eumulgin C03373 (canola oil ethoxylate with 30 ethoxy units) of Henkel KGaA and Ukanil 2507 (castor oil ethoxylate) of Uniqema.
Surfactants may be present in any desired amount. For example, a surfactant may be present in an amount of about 0.1 to about 30% by weight in the formulation. In a particular embodiment, a surfactant is present in an amount of about 1 to about 9% by weight in the formulation. In another embodiment, a surfactant is present in an amount of about 10 to about 20% by weight in the formulation.
An emulsifier is a type of surfactant typically used to maintain dispersion. Non-limiting examples of emulsifiers include Agent 2201-76, Agent 2416-20, Emulpon CO-360, T-Det C-40®, and Agnique™ SBO-10. Agent 2201-76 is manufactured by Stepan Company (22 W. Frontage Road, Northfield, Ill.), which is a blend of nonionic and anionic surfactants (82%). The ingredients in Agent 2201-76 are alkylbenzene sulfonate and fatty acid ethoxylate, aromatic petroleum hydrocarbon, 1-hexanol and naphthalene. Agent 2416-20 is also manufactured by Stepan Company (22 W. Frontage Road, Northfield, Ill.), which is a blend of nonionic and anionic surfactants (35-37%). Agent 2416-20 also includes aromatic petroleum hydrocarbon (57-58%), and naphthalene (6-7%). Emulpon CO-360 is manufactured by Akzo Nobel Chemicals Ltd. (525 West Van Buren, Chicago, Ill.), which contains ethoxylated castor oil (100% by weight) and oxirane (<0.001% by weight). T-Det C-40® may be purchased from Harcros Organics (5200 Speaker Road., P.O. Box 2930, Kansas City, Kans.), or from Akzo Nobel Chemicals Ltd. (525 West Van Buren, Chicago, Ill.), which is a non-ionic emulsifier, and a brand of ethoxylated (polyethoxylated) castor oil. Agnique™ SBO-10 is manufactured by Cognix GmbH headquartered in Monheim, Germany, which contains alkoxylated triglycerides as an ethoxylated soybean oil.
A crop oil, or a crop oil concentrate, may be added, for example, in order to increase the efficacy of a formulation including ipfencarbazone. Although not wishing to be bound by any particular theory, a crop oil is believed to keep the leaf surface moist longer than water, which in turn allows more time for ipfencarbazone to penetrate, thereby increasing the amount of ipfencarbazone that will enter the plant (e.g. weed or crop). A crop oil can improve uptake of ipfencarbazone by plant (e.g. weed or crop). A crop oil can therefore improve, enhance, increase or promote efficacy or activity. Crop oils may contained from 1% to 40% by weight, or 1% to 20% by weight in the formulation. A crop oil can be derived from either petroleum oil or vegetable oil. Non-limiting examples of crop oil include soybean oils and petroleum based oils.
The compositions employed in the methods herein can be in customary formulations. Non-limiting examples include solutions, emulsions, suspensions, wettable powders, powders, dusts, pastes, soluble powders, granules, pellets, emulsifiable concentrate, oil spray, aerosol, natural and synthetic materials impregnated with active compound, and very fine capsules (e.g. in polymeric substances). In certain embodiments, the composition is in a form of an emulsifiable concentrate, wettable powder, granule, dust, oil spray or aerosol.
The compositions may optionally include adherent coatings. Such coatings include those that aid the active ingredient to adhere to the intended environment, for example, a crop plant. Adherent coatings include carboxymethylcellulose, natural and synthetic polymers in various forms, such as powders, granules or latexes. Other adherent coatings include gum arabic, polyvinyl alcohol and polyvinyl acetate. Phospholipids, such as cephalins and lecithins, and synthetic phospholipids are also examples of adherent coatings. Further additives may be mineral and vegetable oils.
Colorants can also be included in the formulations. Non-limiting examples are inorganic pigments, such as iron oxide, titanium oxide and Prussian Blue, and organic dyestuffs, such as alizarin dyestuffs, azo dye-stuffs and metal phthalocyanine dyestuffs, and trace nutrients such as salts of iron, manganese, boron, copper, cobalt, molybdenum and zinc.
Compositions can be applied in the form of ready mixes. Ipfencarbazone can also be formulated individually and mixed upon use, i.e. applied in the form of tank mixes. Ipfencarbazone can be used as such or in the form of their formulations, and furthermore also as mixtures with plant growth stimulants, ready mixes or tank mixes. Compositions may also be mixed with other active compounds, such as herbicides, fungicides, insecticides, acaricides, nematicides, bird repellents, growth substances, plant nutrients and agents which improve soil structure. For particular application purposes, in particular when applied post-emergence, formulations such as mineral or vegetable oils which are tolerated by plants (for example the commercial product “Oleo DuPont 11E”) or ammonium salts such as, for example, ammonium sulphate or ammonium thiocyanate, as further additives can be included.
Ipfencarbazone compositions disclosed herein may also exclude any of the aforementioned. For example, herbicides, fungicides, insecticides, acaricides, nematicides, bird repellents, growth substances, plant nutrients and agents which improve soil structure can be excluded or omitted from a composition or method disclosed herein.
Compositions can be used as such, in the form of their formulations or in the forms prepared therefrom by dilution of a concentrated form, such as ready-to-use or concentrated liquids, solutions, suspensions, emulsions, or solids, such as, powders, pastes, granules and pellets. They are dispersed in the customary manner, for example by watering, spraying, atomizing, dusting or scattering.
Compositions can be produced by mixing or suspending one of, an active ingredient, and optionally a stabilizer, an adjuvant, a diluent or a solvent. In certain embodiments, formulations disclosed herein can be produced, for example by first mixing or suspending one or more stabilizers with a diluent or solvent. Next, the appropriate amount of adjuvants is combined to the resulting mixture containing the stabilizers. An active ingredient, ipfencarbazone, can added at any time, such as at the end, and blended until the formulation becomes mostly or entirely homogeneous.
In particular embodiments, a composition may comprise a second plant growth stimulant. In some embodiments, the plant growth stimulant is selected from the group consisting of ancymidol, butralin, alcohols, chlormequat chloride, cytokinin, daminozide, ethephon, ethylene, flurprimidol, gibberellic acid, gibberellin mixtures, indole-3-butyric acid (IBA), maleic hydrazide, potassium salt, mefluidide, mepiquat chloride, mepiquat pentaborate, naphthalene-acetic acid (NAA), 1-naphthaleneacetamide (NAD), n-decanol, paclobutrazol, prohexadione calcium, trinexapac-ethyl, and uniconazole.

In some embodiments, the composition is provided as a concentrate (e.g., suspension concentrate) and a diluting step is performed prior to the applying step thereby providing a diluted composition. In further embodiments, the applying step comprises spraying the diluted composition. Thus, in various embodiments, the composition comprises a diluent. In particular embodiments, the diluent is selected from the group consisting of water, an aliphatic hydrocarbon, an aromatic hydrocarbon, or an alkyl ester. The amount of diluent in a composition may range from 1% to 99%, or from 30% to 80%. Suitable diluents include, for example, a non-polar water-immiscible solvent, or a polar aprotic water miscible organic solvent. Non-polar solvents include, for example, substituted or unsubstituted aliphatic or aromatic hydrocarbons and esters of plant oils or mixtures thereof. Non-limiting examples of aromatic hydrocarbons include benzene or substituted benzene derivatives such as toluene, xylene, 1,2,4-trimethylbenzene, naphthalene or mixtures thereof. In a more particular embodiment, a solvent includes a mixture of napthalen and 1,2,4-trimethylbenzene. In another more particular embodiment, a solvent is Aromatic 150, a heavy aromatic naptha solvent containing <10% naphthalene and <1.7% 1,2,4-trimethylbenzene.
Alkyl esters can also be used as non-polar, water immiscible diluents. Plant oils may be esterified with various alcohols to form alkyl esters of plant oils. Fatty acids of these plant oils have 5 to 20, or 6 to 15 carbon atoms. Alkyl esters of plant oils include, without limitation, methyl, ethyl and butyl esters of canola (Brassica napus), linseed, safflower (Carthamus tinctorius L.), soybean and sunflower oils.
