Four Chemical Conditioners do not Improve Condition of Four Conifer Seedings in California Test

From 1961 to 1964 the California Division of Forestry conducted studies to compare methods of maintaining four species of conifer seedlings in good physiological condition during storage and shipping. Four commercial chemical plant conditioners and several packaging methods were compared. The preparations used were: Rutex 59, Rutex MCT 1019-1, Rutex W-3 (Foligard), and Shell 4901.2 Packaging methods and materials included: Openend bundles wrapped in waterproof "Fibreen 200" Sisalkraft paper, polyethylene-coated kraft bags (fig. 1), and "Tufflex", a blotter-type paper with high moisture retention qualities. Rutex 59 is a transparent sprayable liquid applied to plant roots to prevent desiccation. Rutex. MTC- 1019-1 is similar to Rutex 59, but has lower pH. Rutex W-3 is also a sprayable liquid, but is designed as a transpiration inhibitor for foliar application.
