Abstract

Immersing the cut stem of flowers for 24-72 hours in a solution containing thiabendazole and sucrose facilitated opening, improved quality, and prolonged vase life of bud cut carnations, mini-carnations and chrysanthemum harvested at the bud stage, and of gladiolus, mini-gladiolus, snapdragons and gypsophila harvested considerably earlier than recommended commercially. This treatment was shown to be more effective than 8-hydroxy-quinoline, in all cases, and more effective than silver nitrate treatment in the case of gypsophila. The flowers treated with thiabendazole were larger and heavier, and retained their decorative value for a longer time. Adding 8-hydroxyquinoline to thiabendazole solutions to form the “TOG” formula improved the effectiveness of the treatment for commercial use and allowed re-usage of the solution several times.
