Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
102 words
A controlled release insecticide composition in the form of an emulsifiable concentrate which consists essentially of: (a) an insecticidal effective amount of Imidan, (b) an amount of acrylic resin effective to controllably release said Imidan, said acrylic resin comprising 30 to 100 wt. % of a C 6 -C 18 alkyl acrylate monomer, (c) an effective amount of a surfactant capable of aiding in the water emulsification of the composition and enhancing the wetting and sticking action of the composition, and (d) an effective amount of a common organic solvent in which said Imidan, said acrylic resin and said surfactant are dissolved.
Claim 2
Dependent Claim
102 words
A controlled release insecticide composition in the form of an emulsifiable concentrate which consists essentially of: (a) an insecticidal effective amount of Imidan, (b) an amount of acrylic resin effective to controllably release said Imidan, said acrylic resin comprising 30 to 100 wt. % of a C 6 -C 18 alkyl acrylate monomer, (c) an effective amount of a surfactant capable of aiding in the water emulsification of the composition and enhancing the wetting and sticking action of the composition, and (d) an effective amount of a common organic solvent in which said Imidan, said acrylic resin and said surfactant are dissolved.
Claim 3
Dependent Claim
20 words
An insecticide composition according to claim 1 wherein the acrylic resin is a copolymer of vinyl acetate and 2-ethylhexyl acrylate.
Claim 4
Dependent Claim
19 words
An insecticide composition according to claim 1 wherein the acrylic resin is a copolymer of styrene and 2-ethylhexyl acrylate.
Claim 5
Dependent Claim
14 words
An insecticide composition according to claim 1 wherein the common organic solvent is xylene.
Claim 6
Dependent Claim
18 words
An insecticide composition according to claim 1 wherein the surfactant is aromatic sulfonate-oxide condensates or alkylphenoxypoly (ethyleneoxy) ethanols.
Claim 7
Dependent Claim
55 words
An insecticide composition according to claim 1 wherein Imidan comprises about 1 to about 40% of the composition, the acrylic resin comprises about 1 to about 30% of the composition, the surfactant comprises about 1 to about 10% of the composition and the weight ratio of solvent to acrylic resin is from 1:1 to 10:1.
Claim 8
Dependent Claim
39 words
A method of controlling foliage eating or chewing insects susceptible to stomach poisons while leaving insects susceptible to contact poisons essentially unaffected which comprises: applying to a foliar substrate an effective amount of the insecticide composition of claim 1.
Claim 9
Independent Claim
44 words
A method of controlling foliage eating or chewing insects susceptible to stomach poisons while leaving insects susceptible to contact poisons essentially unaffected which comprises: applying to a foliar substrate an effective amount of the insecticide composition of claims 2, 3, 4, 5 or 6.
