Abstract
Abstract A latex stimulant and method of use involving a composition comprised of (a) ethephon (2-chloroethylphosphonic acid) and its functional derivatives, (b) and a thickening agent so that the composition may be used to stimulate the flow of latex in rubber trees through direct application by brush to the bark of the tree or to exposed areas wherein the bark has been removed.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
66 words
A composition having significant shelf life under tropical conditions comprising an aqueous medium containing an effective amount of 2-chloroethylphosphonic acid, a polysaccharide gum produced by the fermentation of a carbohydrate by the bacterium Xanthomonas Campestris, said gum being present in an amount of from about 0.5 to about 2.5% by weight of the total composition; and said composition having a viscosity of at least 1,000 cps.
Claim 2
Dependent Claim
66 words
A composition having significant shelf life under tropical conditions comprising an aqueous medium containing an effective amount of 2-chloroethylphosphonic acid, a polysaccharide gum produced by the fermentation of a carbohydrate by the bacterium Xanthomonas Campestris, said gum being present in an amount of from about 0.5 to about 2.5% by weight of the total composition; and said composition having a viscosity of at least 1,000 cps.
Claim 3
Dependent Claim
28 words
The composition of claim 1, wherein the 2-chloroethylphosphonic acid is of a technical grade of about 90% solution by weight with a variance of no greater than 2%.
Claim 4
Dependent Claim
15 words
The composition of claim 1, wherein said composition includes a substantial amount of a fat.
Claim 5
Dependent Claim
15 words
The composition of claim 1, wherein the composition includes a substantial amount of an oil.
Claim 6
Dependent Claim
11 words
The composition of claim 4, wherein said oil is palm oil.
Claim 7
Dependent Claim
19 words
The composition of claim 4, wherein said composition includes an anti-oxidant to retard rancidity and polymerization of the oil.
Claim 8
Dependent Claim
11 words
The composition of claim 1, wherein said composition includes a bactericide.
Claim 9
Independent Claim
88 words
A method of stimulating the flow of latex from a rubber plant comprising applying to said plant an effective amount of a latex flow stimulant composition having significant shelf life under tropical conditions comprising: (a) an aqueous medium containing 2-chloroethylphosphonic acid; (b) a polysaccharide gum produced by the fermentation of a carbohydrate by the bacterium Xanthomonas Campestris; said gum being present in an amount of from about 0.5% to about 2.5% by weight of the total composition; and said composition having a viscosity of at least 1,000 cps.
Claim 10
Independent Claim
88 words
A method of stimulating the flow of latex from a rubber plant comprising applying to said plant an effective amount of a latex flow stimulant composition having significant shelf life under tropical conditions comprising: (a) an aqueous medium containing 2-chloroethylphosphonic acid; (b) a polysaccharide gum produced by the fermentation of a carbohydrate by the bacterium Xanthomonas Campestris; said gum being present in an amount of from about 0.5% to about 2.5% by weight of the total composition; and said composition having a viscosity of at least 1,000 cps.
Claim 11
Dependent Claim
28 words
The method of claim 8, wherein the 2-chloroethylphosphonic acid is of a technical grade of about 90% solution by weight with a variance of no greater than 2%.
Claim 12
Dependent Claim
15 words
The method of claim 8, wherein said composition includes a substantial amount of a fat.
Claim 13
Dependent Claim
15 words
The method of claim 8, wherein said composition includes a substantial amount of an oil.
Claim 14
Dependent Claim
11 words
The method of claim 11, wherein said oil is palm oil.
Claim 15
Dependent Claim
19 words
The method of claim 11, wherein said composition includes an anti-oxidant to retard rancidity and polymerization of the oil.
Claim 16
Dependent Claim
11 words
The method of claim 8, wherein said composition includes a bactericide.
