Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 68 words
In a method for spraying a composition on crops, the improvement which comprises introducing a water soluble composition selected from the group consisting of pesticide, herbicide and fertilizer and at least one nonionic or anionic surfactant into the aqueous medium so that the resulting surfactant concentration in the aqueous medium is less than the critical micelle concentration of the surfactant or surfactant mixture and the composition is solubilized.
Claim 2
Dependent Claim 68 words
In a method for spraying a composition on crops, the improvement which comprises introducing a water soluble composition selected from the group consisting of pesticide, herbicide and fertilizer and at least one nonionic or anionic surfactant into the aqueous medium so that the resulting surfactant concentration in the aqueous medium is less than the critical micelle concentration of the surfactant or surfactant mixture and the composition is solubilized.
Claim 3
Dependent Claim 13 words
The method of claim 1 wherein said water soluble composition is a disinfectant.
Claim 4
Dependent Claim 166 words
The method of claim 1 wherein said nonionic surfactant is selected from the group consisting of: alkyl phenol ethylene oxide condensates wherein the alkyl group contains 8-12 carbon atoms and the condensate contains about 7-18 moles of ethylene oxide per mole of alkyl phenol, of the formula: (C.sub.n H.sub.2n+1)C.sub.6 H.sub.4 (OCH.sub.2 CH.sub.2).sub.x OH wherein n equals at least 8 and (C 2 H 4 O) equals 58 to 78 percent of the total weight of said compound; nonionics represented by the formula: HO(C.sub.2 H.sub.4 O).sub.x (C.sub.3 H.sub.6 O).sub.y (C.sub.2 H.sub.4 O).sub.x' --H where y equals at least 15 and (C 2 H 4 O) x+x' equals 20 to 90 percent of the total weight of said component; nonionics which are ethoxylated partial esters of fatty acids with sugar alcohols containing an average of 1-3 ester groups and up 50 moles of ethylene oxide per molecule; butoxy derivatives of polypropylene oxide, ethylene oxide, block polymers having molecular weights within the range of about 2,000-5,000, and mixtures thereof.
Claim 5
Dependent Claim 15 words
The method of claim 1 wherein the nonionic surfactant is an alkyl phenolethylene oxide condensate.
Claim 6
Dependent Claim 11 words
The method of claim 1 wherein the surfactant is nonylphenol ethoxylate.
