Patent number: 6613542Abstract: In a testing system for chemical substances or substance mixtures, especially for potential plant protection compositions, the chemical substance to be tested or the substance mixture to be tested is applied to a test specimen, especially to plants or parts of plants. When a predetermined period of time has elapsed, the test specimen is examined for the activity of the substance or substance mixture. For this purpose, first of all a type of test specimen is selected from a stock of test specimens, and the substances to be tested are selected from a stock of substances to be tested. The selected type of test specimen and the selected substances are identified (BC1, BC2) by means of a machine-readable code and those codes are supplied to a memory unit (12).Type: GrantFiled: June 14, 2001Date of Patent: September 2, 2003Assignee: Syngenta Crop Protection, Inc.Inventors: Jörg Mentzen, Helmut Kessmann, Harald Danigel, Gerhard Klokow, Peter Obergfell

Patent number: 6031153Abstract: The present invention concerns a method of protecting plants from pathogen attack through synergistic disease resistance attained by applying a conventional microbicide to immunomodulated plants. Immunomodulated plants are those in which SAR is activated and are therefore referred to as "SAR-on" plants. Immunomodulated plants may be provided in at least three different ways: by applying to plants a chemical inducer of SAR such as BTH, INA, or SA; through a selective breeding program based on constitutive expression of SAR genes and/or a disease-resistant phenotype; or by transforming plants with one or more SAR genes such as a functional form of the NIM1 gene. By concurrently applying a microbicide to an immunomodulated plant, disease resistance is unexpectedly synergistically enhanced; i.e., the level of disease resistance is greater than the expected additive levels of disease resistance.Type: GrantFiled: December 23, 1997Date of Patent: February 29, 2000Assignee: Novartis AGInventors: John Andrew Ryals, Leslie Bethards Friedrich, Scott Joseph Uknes, Antonio Molina-Fernandez, Wilhelm Ruess, Gertrude Knauf-Beiter, Ruth Beatrice Kung, Helmut Kessmann, Michael Oostendorp

Patent number: 5804693Abstract: The present invention provides chemically regulatable DNA sequences capable of regulating transcription of an associated DNA sequence in plants or plant tissues, chimeric constructions containing such sequences, vectors containing such sequences and chimeric constructions, and transgenic plants and plant tissues containing these chimeric constructions. In one aspect, the chemically regulatable DNA sequences of the invention are derived from the 5' region of genes encoding pathogenisis-related (PR) proteins. The present invention also provides anti-pathogenic sequences derived from novel cDNAs coding for PR proteins which can be genetically engineered and transformed into plants to confer enhanced resistance to disease.Type: GrantFiled: May 31, 1995Date of Patent: September 8, 1998Assignee: Novartis Finance CorporationInventors: Thomas D. Gaffney, John A. Ryals, Leslie B. Friedrich, Scott J. Uknes, Eric R. Ward, Helmut Kessmann, Bernardus T. Vernooij
