  • Biological control of phytophthora on plants and in soil with Myrothecium roridum ATCC 20963, 20964 or 20965
    Patent number: 5314691
    Abstract: Plant pathogenic fungi belonging to the genus Phytophthora such as phytophthora cinnamomi which causes root rot in plants is biologically controlled with strains of fungi belonging to the genus Myrothecium. Preferred strains of Myrothecium are Myrothecium roridum ATCC 20963, 20964 or 20965. An inoculum containing Myrothecium and a substrate such as bran or a branalginate mixture is added to the surface of a plant or to soil. The Myrothecium may be grown on the substrate 5 to 7 days before use of the inoculum.

  • Composition and method for removing sulfide-containing scale from metal surfaces
    Patent number: 4220550
    Abstract: Sulfide-containing scale is removed from metal surfaces by contacting the encrusted surface with an aqueous acid cleaning solution having an aldehyde (e.g., formaldehyde) dissolved or dispersed in the acid in an amount sufficient to prevent the evolution of hydrogen sulfide gas.

  • Avocado tree called Barr Duke
    Patent number: PP6627
    Abstract: A new and distinct rootstock variety of avocado tree characterized by its high yield resistance to Phytophthora root rot caused by Phytophthora cinnamomi. This variety has a high level of resistance comparable to the `Duke 7` rootstock variety. It is also characterized under some field conditions by producing a somewhat smaller tree, when grafted with a `Haas` scion, than that typical of a `Duke 7` rootstock.

    Inventors: Michael D. Coffey, Fred B. Guillemet
  • Avocado tree called Thomas
    Patent number: PP6628
    Abstract: A new and distinct rootstock variety of avocado tree characterized by its high field resistance to Phytophthora root rot caused by Phytophthora cinnamomi. This variety has the highest level of resistance of any rootstock currently identified. It is characterized by relative ease of propagation using the etiolation method and graft compatibility with commercial scion varieties, including `Hass`, `Gwen` `Pinkerton`, `Fuerte`, `Bacon` and `Zutano`.
