ABSTRACT:
TECHNICAL FIELD OF THE INVENTION
The present invention relates to compositions and methods, which can provide a pesticidal effect over pests.
BACKGROUND OF THE INVENTION
Various types of compositions have heretofore been developed and utilized in order to provide a pesticidal effect.
U.S. Pat. No. 4,751,225 describes 4-phenoxyphenyl 2-(2-pyridyloxy)propyl ether. The common name of 4-phenoxyphenyl 2-(2-pyridyloxy)propyl ether is pyriproxyfen.
U.S. Pat. No. 5,288,710 describes an ether compound encompassed by formula I:
wherein R represents a methyl group or an ethyl group.
SUMMARY OF THE INVENTION
The present invention provides compositions and methods. The composition comprises 4-phenoxyphenyl 2-(2-pyridyloxy)propyl ether and an ether compound encompassed by formula I:
wherein R represents a methyl group or ethyl group.
The method comprises applying a pesticidally effective amount of the composition to a pest or a habitat of the pest.
DETAILED DESCRIPTION OF THE INVENTION
The ether compounds encompassed by formula I and 4-phenoxyphenyl 2-(2-pyridyloxy)propyl ether are typically utilized as pesticidally active ingredients in the compositions of the present invention.
The compositions of the present invention may have present therein a mixture of the ether compounds encompassed by formula I. In such cases, the compositions may have a mixture of an ether compound encompassed by formula I, wherein in formula I, R represents an ethyl group with an ether compound encompassed by formula I, wherein in formula I, R represents a methyl group. The mixture thereof wherein the ether compound encompassed by formula I, wherein in formula I, R represents an ethyl group is approximately 90% by weight is known as an emamectin benzoate, wherein said weight percentage is based on the total weight of the provided mixture thereof. As the mixture thereof, the emamectin benzoate can be utilized in the compositions.
In the compositions, the ether compounds encompassed by formula I and 4-phenoxyphenyl 2-(2-pyridyloxy)propyl ether are typically present therein at an amount of 0.01 to 90% by weight and preferably 0.1 to 80% by weight, wherein said weight percentages are based on the total weight of the provided composition.
The typical weight to weight ratio of the ether compounds encompassed by formula I to 4-phenoxyphenyl 2-(2-pyridyloxy)propyl ether is to have for 1 part by weight of the ether compounds encompassed by formula I, 1 to 200 parts by weight of 4-phenoxyphenyl 2-(2-pyridyloxy)propyl ether, and preferably 10 to 100 parts by weight of 4-phenoxyphenyl ether, based on the total weight of the ether compounds encompassed by formula I and 4-phenoxyphenyl 2-(2-pyridyloxy)propyl ether in the compositions.
Such weight to weight ratios and amounts of the ether compounds encompassed by formula I and 4-phenoxyphenyl 2-(2-pyridyloxy)propyl ether can provide a pesticidally synergistic effect over the pest, when applied to a pest or a habitat of a pest.
The compositions can possess various forms in which the ether compounds encompassed by formula I and 4-phenoxyphenyl 2-(2-pyridyloxy)propyl ether are utilized as is, or as a formulation, with examples of such formulations including liquid formulations such as an oily formulation, emulsifiable concentrate, flowable and aerosol; solid formulations such as wettable powder, resin formulation, granule, dust and poison bait; and the like.
The formulations of the present invention can be formulated by conventional methods by which an ether compound encompassed by formula I and 4-phenoxyphenyl 2-(2-pyridyloxy)propyl ether are supported, dissolved or dispersed in a carrier selected accordingly to the formulation form, such as a solid carrier and a liquid carrier.
Examples of the solid carrier include clays such as kaolin clay, diatomaceous earth, synthetic hydrated silicon oxide, bentonite, Fubasami clay and terra alba; talcs; inorganic minerals such as ceramic, sericite, quartz, sulfur, activated carbon, calcium carbonate and naturally-occurring hydrated silica; chemical fertilizers such as ammonium sulfate, ammonium phosphate, ammonium nitrate, urea and ammonium chloride; resins such as polyolefin resin (e.g., low density polyethylene, high density polyethylene and polypropylene) and urethane resins (e.g., polyurethane); and the like.
Examples of the liquid carriers include water; alcohols such as methanol and ethanol; ketones such as acetone and methyl ethyl ketone; aromatic hydrocarbons such as benzene, toluene, xylene, ethylbenzene and methylnaphthalene; aliphatic hydrocarbons such as hexane, cyclohexane, kerosene and gas oil; esters such as ethyl acetate and butyl acetate; nitrites such as acetonitrile and isobutyronitrile; ethers such as diisopropyl ether and dioxane; acid amides such as N,N-dimethylformamide and N,N-dimethylacetamide; halogenated hydrocarbons such as dichloromethane, trichloroethane and carbon tetrachloride; dimethyl sulfoxide; and vegetable oils such as soybean oil and cottonseed oil.
Optionally, a formulation adjuvant may be added to the formulations of the present invention, such as a surfactant, adhesive agent, dispersant, thixotropy-conferring compounds, stabilizer, propellant, anti-foaming agent, rust preventive agent, antifreeze, plasticizer, dye, pigment and the like.
More specifically, examples of the surfactant include alkyl sulfate ester salts, alkylsulfonate salts, alkylarylsulfonate salts, alkylaryl ethers, polyoxyethylenated derivatives of alkylaryl ethers, polyethyleneglycol ethers, polyvalent alcohol esters, sugar alcohol derivatives and the like.
Examples of the adhesive agents and dispersants include casein; gelatin; saccharides such as starch, gum arabic, cellulose derivatives and alginic acid; lignin derivatives; bentonite; and synthetic water-soluble polymers such as polyvinyl alcohol, polyvinylpyrrolidone and polyacrylic acids.
Examples of the thixotropy-conferring compounds include bentonite, aluminum magnesium silicate, xanthan gum, polyacrylic acid and the like.
Examples of the stabilizers include PAP (isopropyl acid phosphate), BHT (2,6-di-tert-butyl-4-methylphenol), BHA (2-tert-butyl-4-methoxyphenol and 3-tert-butyl-4-methoxyphenol), fatty acids such as stearic acid, fatty acid esters, vegetable oils such as soybean oil and cotton seed oil, mineral oils such as naphthalene, kerosene and diesel oil, and the like.
Examples of the propellants include carbon fluorocarbon gas, butane gas, LPG (liquefied petroleum gas), dimethyl ether, carbon dioxide and the like.
Examples of the anti-foaming agent include silicon resin mixtures such as ANTIFOAM C (manufactured by Dow Corning Corporation) and TSA730 (manufactured by GE Toshiba Silicones Company Limited), and the like.
As an example of the rust preventive agents, there is mentioned sodium benzoate.
Examples of the antifreeze include glycols such as ethylene glycol and polyethylene glycol, and the like.
Examples of the plasticizers include phthalate esters, stearic acids and the like.
Examples of the dyes or pigments include azo dyes such as disazo yellow and first yellow, and the like.
When utilized, the formulation adjuvant may be present in the formulations in an amount of from 0.001 to 50% by weight, and preferable from 0.01% to 30% by weight, wherein said weight percentages are based on the total weight of the provided composition.
The aerosol can be obtained by conventional methods, such as by packing the propellant and an oily formulation, emulsifiable concentrate or flowable comprising an ether compound encompassed by formula I and 4-phenoxyphenyl 2-(2-pyridyloxy)propyl ether, into an aerosol container having a propelling device, such as a spray can.
The poison bait of the present invention can be obtained by methods in which the ether compounds encompassed by formula I and 4-phenoxyphenyl 2-(2-pyridyloxy)propyl ether are mixed with the bait ingredients and other ingredients. Examples of the bait ingredients utilized to obtain the poison bait include grain powders, vegetable oils, saccharides, crystalline cellulose and the like. Examples of the other ingredient
