ABSTRACT:
FIELD OF THE INVENTION
The instant invention relates to pesticidal compositions which control pests which are harmful to materials containing cellulose, and methods of controlling said pests.
BACKGROUND OF THE INVENTION
Pests which are harmful to materials containing cellulose, are usually known to tamper with materials containing cellulose, such as timbers, veneers, engineering woods, papers and the like. In this regard, structures which are produced from the materials containing cellulose (such as residential structures, historic structures and the like) are frequently affected by the pests in a negative manner. As an attempt to efficiently control pests which are harmful to materials containing cellulose, certain pesticidal compositions have contained chlordane as an active ingredient. However, sales of the pesticidal compositions containing chlordane have been halted, in view of a presumed long or short term harm that is introduced into the surrounding environment of where the provided pesticidal composition comprising chlordane is being utilized.
As a result, the pesticidal compositions attempting to control said pests have been swayed to otherwise comprise pesticidally alternative active ingredients that are distinct from chlordane when the objective of the pesticidal composition was to control pests which are harmful to materials containing cellulose, and that be commercially available for sales. Such commercially available pesticidal compositions have contained organophosphorous compounds such as chlorpyriphos, phoxim and fenitrothion; pyrethroid compounds such as permethrin, bifenthrin, silafluofen, cypermethrin, acrinathrin and tralomethrin; and neonicotinoid compounds such as imidacloprid, in order to control pests which are harmful to materials containing cellulose. Even if so, the pesticidal compositions containing such alternative active ingredients have failed to be thoroughly advantageous in controlling pests which are harmful to materials containing cellulose.
SUMMARY OF THE INVENTION
The instant invention provides for pesticidal compositions that control pests which are harmful to materials containing cellulose, and methods of controlling said pests. In this regard, such pesticidal compositions are advantageous in that the pesticidal composition of the instant invention can typically control said pests at a low dosage. Such pesticidal compositions are also advantageous in that the provided pesticidal composition can provide a residual effect, which would control said pests for an extended amount of time. Further, such pesticidal compositions are also advantageous in that said pesticidal compositions control pests which are harmful to materials containing cellulose without introducing a notable amount of harm to the surrounding environment of which the provided pesticidal composition is being utilized.
In order to meet the objectives of the instant invention, a pesticidal composition of the instant invention comprises 3,5-dichloro-1-(3,3-dichloro-2-propenyloxy)-4-[3-(5-trifluoromethylpyridin-2-yloxy) propyloxy] benzene and an inert carrier, and a method of the instant invention comprises utilizing the active ingredient compound of said pesticidal compositions.
DETAILED DESCRIPTION OF THE INVENTION
A pesticidal composition of the instant invention comprises 3,5-dichloro-1-(3,3-dichloro-2-propenyloxy)-4-[3-(5-trifluoromethylpyridin-2-yloxy) propyloxy]benzene as an active ingredient, in order to control pests which are harmful to materials containing cellulose. A method to produce the instant active ingredient is disclosed in Japanese unexamined patent 9-151172. The pesticidal compositions of the instant invention comprise the instant active ingredient in an amount that effectively controls pests which are harmful to materials containing cellulose, and in an amount which also depends on the formulation of the inventive pesticidal composition or the method in which the inventive pesticidal composition is being used. As such, the amount of the instant active ingredient which effectively controls pests in a typical pesticidal composition of the instant invention is preferably in an amount of from about 0.001% to 99% by weight, and is more preferably in an amount of from about 0.01% to 50% by weight, but is not limited thereto.
The pesticidal compositions of the instant invention also typically comprise an inert carrier, in an amount in which the inert carrier can assist the instant active ingredient to be carried through a process or method of controlling pests which are harmful to materials containing cellulose. As such an amount of the inert carrier, the inventive pesticidal compositions preferably comprise the inert carrier in an amount of from about 10% to 99.9%, provided that such a carrier is a solid, liquid or gas carrier, or a combination thereof. In such a case, examples of the solid carriers that may be in the pesticidal compositions of the instant invention include clays such as kaolin, diatomaceous earth, bentonite, fubasami clay and terra alba, synthetic hydrated silicon oxides, talc, ceramics, other inorganic minerals which are useful in producing formulated compositions such as sericite, quartz, sulfur, active carbons and calcium carbonate, chemical fertilizers such as ammonium sulfate, ammonium phosphate, ammonium nitrate, urea and ammonium chloride, and the like, as well as powders thereof, granules thereof, and a mixture thereof; examples of the liquid carriers that may be in the pesticidal compositions of the instant invention include water, alcohols such as methanol and ethanol, aromatic hydrocarbons such as toluene, xylene, ethylbenzene and methyl naphthalene, non-aromatic hydrocarbons such as hexane, cyclohexane, kerosene and light oils, esters such as ethyl acetate and butyl acetate, nitrites such as acetonitrile and isobutylonitrile, ethers such as diisopropyl ether and dioxane, amides such as N,N-dimethylformamide and N,N-dimethylacetamide, halogenated hydrocarbons such as dichloromethane, trichloroethane and carbon tetrachloride, dimethylsulfoxide, botanical oils such as soy oil and cotton seed oil, and the like, and a mixture thereof; and examples of the gas carriers that may be in the pesticidal compositions of the instant invention include propellants such as butane gas, liquid petroleum gas, dimethyl ether, carbonated gas, and the like, and a mixture thereof.
Further, the pesticidal compositions of the instant invention may additionally contain a coloring agent, a formulation auxiliary, or a combination thereof. As such, examples of such coloring agents that may be utilized in the pesticidal compositions of the instant invention include inorganic pigments such as metal oxides, titanium oxides and Prussian blue, organic dyes such as alizarine dyes, azo dyes and metallic phthalocyanine dyes, iron, manganese, boron, copper, cobalt, molybdenum, zinc and salts thereof, and the like, or a mixture thereof; and examples of such formulation auxiliaries that may be utilized in the pesticidal compositions of the instant invention include attaching and/or dispersing agents, surfactants, stabilizers, and the like, or a mixture thereof.
In the event that the attaching and/or dispersing agents are selected to be utilized as said formulation auxiliary in the pesticidal compositions of the instant invention, the attaching and/or dispersing agents are typically agents that help evenly disperse certain particles which are present in the inventive pesticidal compositions, help adhere the provided pesticidal composition to locations which the pesticidal composition is utilized upon, or a combination thereof. Exemplarily of such an attaching and/or dispersing agent that may be utilized in the inventive pesticidal compositions include caseins, gelatins, sugars such as starch, gum arabic, cellulose derivatives and alginic acids, lignin derivatives, betonite, synthetic water-soluble polymers such as polyvinyl alcohol, polyvinylpyrrolidone and polyacrylic acid, and the like, or a mixture thereof.
Examples of the surfactants that may be utili
