Abstract The vase life of irises (Iridaceae Hollandica ‘Telstar’) was determined before and after gamma irradiation in the Missouri S&T Research Reactor (MSTR) at 20, 80, 457, 1060, and 1473 Gy. It was determined that vase life improves by as much as 7% for the 20 Gy irradiation. At about 100 Gy the vase life is comparable to non-irradiated flowers. Unfortunately pest control requires 200–300 Gy. At 457 Gy the vase life is about 15% shorter, and it gets worse at higher doses (30% lower vase life at 1 kGy). Gamma irradiation of irises can be a viable method of pest control, but the irradiation dose should be kept as low as possible while still achieving the phytosanitary objectives depending on the type of pest to control.
