Claims Analysis

Total Claims: 26
Claim 1
Independent Claim 41 words
A root crop growth promotant concentrate for the preparation of root crop growth promotant compositions, said concentrate comprising a pseudomonad selected from the group consisting of Pseudomonas putida BK-1, Pseudomonas fluorescens TL-3 and Pseudomonas fluorescens SH-5 and an agronomically acceptable carrier.
Claim 2
Dependent Claim 41 words
A root crop growth promotant concentrate for the preparation of root crop growth promotant compositions, said concentrate comprising a pseudomonad selected from the group consisting of Pseudomonas putida BK-1, Pseudomonas fluorescens TL-3 and Pseudomonas fluorescens SH-5 and an agronomically acceptable carrier.
Claim 3
Dependent Claim 13 words
The concentrate of claim 1 wherein said pseudo-monad is suspended in said carrier.
Claim 4
Dependent Claim 13 words
The concentrate of claim 1 wherein said pseudo-monad is adsorbed onto said carrier.
Claim 5
Dependent Claim 13 words
The concentrate of claim 1 wherein said pseudo-monad is admixed with said carrier.
Claim 6
Dependent Claim 34 words
A root crop growth promotant composition comprising an effective amount of a pseudomonad selected from the group consisting of Pseudomonas putida BK-1, Pseudomonas fluorescens TL-3, and Pseudomonas fluoresce SH-5 and an agronomically acceptable carrier.
Claim 7
Dependent Claim 34 words
A root crop growth promotant composition comprising an effective amount of a pseudomonad selected from the group consisting of Pseudomonas putida BK-1, Pseudomonas fluorescens TL-3, and Pseudomonas fluoresce SH-5 and an agronomically acceptable carrier.
Claim 8
Dependent Claim 12 words
The composition of claim 5 wherein said composition is a wettable powder.
Claim 9
Dependent Claim 11 words
The composition of claim 5 wherein said composition is a dust.
Claim 10
Dependent Claim 12 words
The composition of claim 5 wherein said composition is in granular form.
Claim 11
Dependent Claim 12 words
The composition of claim 5 wherein said composition is an emulsifiable oil.
Claim 12
Dependent Claim 42 words
A method of improving the yield of root crops comprising applying an effective amount of a composition of claim 5 to a root crop seed, seed piece, tuber, plant or soil in which said seed, seed piece, tubers, or plant is planted.
Claim 13
Dependent Claim 24 words
The method of claim 10 wherein said composition comprises from about 105 to 109 cells/ml. of said pseudo-monad. CLAIMS SUPPORTED BY THE SUPPLEMENTARY DISCLOSURE
Claim 14
Dependent Claim 26 words
A root crop growth promotant comprising (a) at least one pseudomonad selected to promote the growth of a root crop and (b) an agronomically acceptable carrier.
Claim 15
Dependent Claim 26 words
A root crop growth promotant comprising (a) at least one pseudomonad selected to promote the growth of a root crop and (b) an agronomically acceptable carrier.
Claim 16
Dependent Claim 19 words
A promotant as in claim 12, wherein the pseudomonad is selected from the species Pseudomona putida and Pseudomona fluorescens.
Claim 17
Dependent Claim 22 words
A promotant as in claim 12, wherein the pseudomonad is selected from the group consisting of Pseudomonas strains A-l, B-10, and E-6.
Claim 18
Dependent Claim 27 words
A promotant as in claim 12, wherein the pseudomonad is present in the carrier at a concentration effective to promote growth when applied to seeds before planting.
Claim 19
Dependent Claim 20 words
A promotant as in claim 15, wherein the effective concentration is in the range from about 105 to 109 cells/ml.
Claim 20
Dependent Claim 15 words
A promotant as in claim 15 or 16 in the form of a wettable powder.
Claim 21
Dependent Claim 12 words
A promotant as in claim 15 or 16 in a dust form.
Claim 22
Dependent Claim 11 words
A promotant as in claim 15 or 16 in granular form.
Claim 23
Dependent Claim 15 words
A promotant as in claim 15 or 16 in the form of an emulsifiable oil.
Claim 24
Dependent Claim 40 words
A promotant as in claim 12, 13 or 14, wherein the pseudomonad is present in the carrier at a concentration higher than required to be effective in promoting growth and may be mixed with additional agronomically acceptable carrier before use.
Claim 25
Dependent Claim 33 words
A method for improving the yield of root crops comprising applying an effective amount of the promotant of claim 12, 13 or 14 to a root crop seed prior to planting the seed.
Claim 26
Dependent Claim 35 words
A method for improving the yield of root crops comprising applying an effective amount of the promotant of claim 12, 13 or 14 to the soil where a root crop seed is to be planted.
