Patent number: 5219825Abstract: The invention relates to synergistic herbicidally active compositions. The quantity required for a given herbicidal effect is substantially lower than that required for the herbicide itself. The compositions of the invention comprise in combination a herbicide which brings about active oxygen species formation in plants and a substance which binds copper or zinc, or a substance which reacts with a thiol moiety of a thiol containing enzyme. The herbicide and metal binding or thiol binding component can be applied together or separately.Type: GrantFiled: November 9, 1987Date of Patent: June 15, 1993Assignee: Yeda Research and Development Co., Ltd.Inventors: Jonathan Gressel, Joseph Shaaltiel

Patent number: 5217738Abstract: A method for the treatment of a harvested plant part with L(+) adenosine or 1-triacontanol to improve the quality of the parts, such as fruit, vegetables (including root vegetables) and leaves. The method includes applying the L(+) adenosine or 1-triacontanol to the part of the plant after harvest of the fruit or vegetable. The acidity or sugar content of the plant part and thus the sugar to acid ratio is particularly affected by the treatment.Type: GrantFiled: April 17, 1992Date of Patent: June 8, 1993Assignee: Board of Trustees operating Michigan State UniversityInventor: Stanley K. Ries
