Abstract
Abstract The method for reducing the temperature at which freezing takes place in plants to reduce frost damage by the addition of non-ice nucleating bacteria to the plants prior to the onset of freezing temperature and preferably while the plants are in their seedling stage.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
63 words
The method for protecting plants against frost injury comprising treating the plants by the application of non-ice nucleating bacteria in an amount sufficient to increase the population prior to the onset of freezing temperature to increase the proportion of non-ice nucleating bacteria to ice nucleating bacteria from that normally present on the plants thereby to reduce the temperature at which frost injury occurs.
Claim 2
Independent Claim
63 words
The method for protecting plants against frost injury comprising treating the plants by the application of non-ice nucleating bacteria in an amount sufficient to increase the population prior to the onset of freezing temperature to increase the proportion of non-ice nucleating bacteria to ice nucleating bacteria from that normally present on the plants thereby to reduce the temperature at which frost injury occurs.
Claim 3
Dependent Claim
25 words
The method as claimed in claim 1 in which the non-ice nucleating bacteria applied to the plants are bacteria which interfere with the ice-nucleating bacteria.
Claim 4
Dependent Claim
21 words
The method as claimed in claim 2 in which the interfering non-ice nucleating bacteria are antagonistic to the ice nucleating bacteria.
Claim 5
Dependent Claim
25 words
The method as claimed in claim 2 in which the interfering non-ice nucleating bacteria interfere by occupying sites for growth of the ice nucleating bacteria.
Claim 6
Dependent Claim
26 words
The method as claimed in claim 1 in which the treatment to add the non-ice nucleating bacteria is made during an early stage of plant growth.
Claim 7
Dependent Claim
27 words
The method as claimed in claim 1 in which the treatment to apply the non-ice nucleating bacteria is made while the plant is in the seedling stage.
Claim 8
Dependent Claim
29 words
The method as claimed in claim 1 in which the bacteria are provided in an aqueous suspension and treatment is carried out by spraying the plants with the suspension.
Claim 9
Dependent Claim
29 words
The method as claimed in claim 1 in which the treatment of add the non-ice nucleating bacteria is made during the budding stage in the case of perennial plants.
Claim 10
Dependent Claim
52 words
A composition for topical application to plants for protection of the plants against frost injury comprising a carrier, and non-ice nucleating bacteria and a nutrient suitable for the bacteria admixed with the carrier, in which the non-ice nucleating bacteria are interfering bacteria which are antagonistic to or compete with ice nucleating bacteria.
Claim 11
Dependent Claim
52 words
A composition for topical application to plants for protection of the plants against frost injury comprising a carrier, and non-ice nucleating bacteria and a nutrient suitable for the bacteria admixed with the carrier, in which the non-ice nucleating bacteria are interfering bacteria which are antagonistic to or compete with ice nucleating bacteria.
Claim 12
Dependent Claim
30 words
A composition as claimed in claim 9 in which the non-ice nucleating bacteria are present in the suspension in an amount within the range of 10 6 -10 8 cells/ml.
Claim 13
Dependent Claim
21 words
A composition as claimed in claim 9 in which the carrier is water in which the non-ice nucleating bacteria are suspended.
