Abstract: A method is for prevention and/or biological control of wilt caused by Ralstonia solanacearum, by use of suitable bacteriophages. In addition a method uses the structural characterisation, genome sequence and activity of three specific lytic bacteriophages of R. solanacearum. Podovirus presents an elevated stability between 4° C. and 30° C. in an aqueous medium in the absence of a host. As a result of the high level of stability, lytic activity, elevated specificity towards R. solanacearum and the absence of activity against the microbiota associated with the plants to be protected, bacteriophages are used for the biological control of R. solanacearum in river courses and irrigation water, as well as in a method for preventing and/or controlling the wilt produced by the bacteria, in which at least one of the bacteriophages, or combinations thereof, are delivered to the plants and/or the soil in the irrigation water.

Abstract: The invention provides a method for controlling Huanglongbing (HLB) disease of citrus plants through expressing genes encoding synthases for sesquiterpenes such as ?-caryophyllene, and ?-copaene, and combinations thereof, in citrus plants. Methods of controlling HLB comprising applying at least one purified sesquiterpene, which repels Diaphorina citri and/or Tryoza erytrae psyllid insects, so as to control the HLB disease of citrus plants, are also disclosed.

Abstract: A new and distinct triploid Citrus hybrida cultivar is provided that is the product of controlled cross-pollination of two diploid parental plants. The new cultivar forms attractive obloid-shaped late-maturing substantially seedless fruit having an excellent mildly acidic flavor and a pleasant aroma. The leaves are dark green in coloration. The growth habit is vigorous and drooping.

Abstract: A new and distinct triploid Citrus hybrida cultivar is provided that is the product of controlled cross-pollination of two diploid parental plants. The new cultivar forms attractive seedless obloid-shaped, medium-late-maturing fruit with a convex base having an excellent mildly acidic flavor. The leaves are dark green in coloration. The growth habit is vigorous and erect-drooping.
