Inventor: HEYDECK PAUL DR
IPC: A01N63/28
Filed: 1991-09-27
Abstract: Pre-treatment of seeds, esp. those of woodland trees, with nourseothricin prepns. is claimed. Nourseothricin prepns. are known from DD 161182, DD 216161, DD 249713 and EP 0126256. USE/ADVANTAGE - Although the method is esp. applicable to seeds of woodland trees, partic. conifers such as Pinus sylvestris and Larix decidua, it can also be applied to seeds of ornamental plants and to seeds generally used in horticulture.
