It would be highly desirable to have a technique for r~alizing control of woody plants and unde~ira~le organisms that infest said plants that obviated the afore-mentioned disadvantages, e.g., a low cost, low volume, injury specific application technique that could be u~ilized in any season without the use of dangerously sharp instruments.
SUMMAR~ OF TH13 I~IVENTION
This invention relates to the discovery.
15. that esters of phosphoric and phthalic acid~ are effective wood penetrant-carriers or fungicides, insesticides, herbicides, and plant growth regulators. The aforementioned penPtrant-carriers are especially ef~ective when the active ingredients are oil-soluble and/or oil miscible. Basal spray compositions using these penet.rants can be effectively uRed a) with 1/10 of the total conventional volume - thus eliminating the necessity o~ transporting large volumes of expensive fuel oil to the use site; b) in any season - the absence of water eliminates freezing problems; and c) with herbicides o limited soil activity thus eliminating or significantly reducing potential injury to off-target vegetation.
~ETAILED DESCRIPTIO~ OF THE INVENTION
This invention relates to compositions comprising a penetrant-carrier in combination with a ~-13722 æ~
herbicide, plant growth .regulator, fungicide, or insecticide, all the aforementioned hereinafter generically referred to as biocides, and the use of this composition in a basal spray to control woody plants, regulate the growth of said plants or control organisms which infest said plants.
The term "basal spray" means that the composition is applied usually via conventional low volume spray apparatus, to the stem or bark of a woody plant, usually a~ the ba~al portion of the plant. Generally, the composition is sprayed onto from about a 12 to 36 inch portion of the lower end of the ~tem, i.e., that end of the st~m closest to the ground or trunk.
The penetrants of this invention are a) compounds o~ phosphorous having the formula:
/Xl~l ()n = P X2R2 ~X3R3 wherein xl, x2 and X3 are individually O or S;
n is 0 ~r l;
R1 is selected from the group consi~ting of hydrogen, Cl to ClO alkyl, aryl, aryl-~Cl-cl0) alkyl, cycloaliph 2~ and heterocyclic; and R2 and R3 are individually selec~ed from the group consisting o~ Cl-ClO
alkyl, aryl, aryl-(C~-C10) alkyl, cycloaliphatic~ and heterocyclic.
In other words, at least two of the groups attached to the oxygens/sulfurs connected by a ~zo~æ~
single bond to the phosphorous group are organic groups, while the other is e.ither an organic group or hydrogen.
~) esters of phthalic acid having the formula C O - R
wherein Rl,and R2 are individually selected from the group consistlng of hydrogen, Cl-ClO
alkyl, aryl. and aryl-(C1-ClO)alkyl with the proviso that Rl and R2 cannot both be hydrogen, c) and combinations of the a~ove-described phosphoric and phthalic acid esters.
The preferred penetrant-carriers are the following:
symmetrical triaryl phosphate esters such as triphenyl phosphate;
tricresyl phosphate (all isomers); and tri(O-cresyl) phosphate, unsymmetrical triaryl phosphate esters such as cresyl diphenyl phosphate ester;
alkyl diaryl phosphate esters such as 2-ethylhexyl diphenyl phosphate;
dialkyl phosphate esters such as dibutyl phosphate;
~208~
trialkyl phosphate esters such as tributyl phosphate;
trldecyl phosphate' triethyl phosphate; and tri(2-ethylhexyl~ phosphate:

mono- and di-alkyl phthalate e~ters such as dibutyl phthalate; and dioctyl phthalate.
The most preferred penetrant-carrier of this invention is tributyl phosphate Although the effectiveness in basal sprays of most herbicide~, fungicides, insectici~es an~
plan growth regulators can be enhanced via the u~ilization of the penetrant-carriers of this invention, the preferred active ingredients are oil soluble or oil miscible.
~he preferred active ingredients of this invention are, for example, herbicides which are phenoxy acids and e~ters such as:
2,4-dichlorophenoxypropionic acid, butoxy-ethanol ester, 2,4-dichlorophenoxyacetic acid, butoxy-ethanol ester.

Other preferred herbicides include 4-amino-3,5,6-trichloropicolinic acid, 2-methoxy-3,6-dichlorobenzoic acid~ and
plants, but they are subject to disadvantages such as high cost; injury to off-target vegetation from root uptake; limited use at below freezing temperatures; and the necessary use of sharp, dangerous tools to cut the woody plant stems.

Other preferred herbicides include 4-amino-3,5,6-trichloropicolinic acid, 2-methoxy-3,6-dichlorobenzoic acid~ and
3~5,6-trichloro-2-pyridinyloxyacetic acid.
Combinations of the above with themselves or with other active ingredients can also be desirable since two or more of the effective, i,eO
active, ingredien~s can be used in combination to incr~ase the number of species of woody plants or plant pests which can be controlled.
This invention utilizes an amount of active biocide equivalent to that used in a conventional basal or stump spray for control o~ woody plants or plant pests but uses a significantly lower volume of penetrant-carrier or combination of carriers in lieu of the conventional larger volume of fuel oil or kerosene.
Whereas a conventional basal herbicidal spray would apply from 30 to 100 gallons per acre of a herbicide/oil mixture containing about 1 to 20, preferably about 5 to about 16 pounds o~ a phenoxy herbicide, with the instant invention only from about 1 to about 15, pre~rably fro~ about 3 to lO
total gallons containing the same amount of active 2S herbicide would be applied per acre. Usually the preferred amount o~ spray volume needed is about l/lOth the amount of actiYe oil-carrier spray volume conventionally used.
A solvent diluent is preferably mixed with the active~penetrant combinations to solubilize the active and obtain desired active concentration for good spray distribution, iOe, good dispersion with conventional equipment~
~-13722 2~
Although many organic diluents would suffice - the choice being usually governed by economics - the preferred solubili2lng diluents consist o~ about 90 percent naphthenic oil with the balance being kerosene.
The ratio of biocidally active ingredient to the penetran~ should range from a minimum of about 1030 to a maximum of about 20:1, preferably from about 1:10 to about 2:1 and most preferably ~0 from about 1:1.5 to about 1.~
The solvent diluent is present in the basal concentrate at a ratio of solvent diluent to active biocidal ingredient at from about 0 to about 25, preferably from about 0~2 to about 10 and most prefera~ly from about 0~5 to about 4 time~ the active ingredient~
