ANTHURIUM: Anthurium andraeanum cv. Ozaki, Seapearl , Nitta, Mauna Kea, Marian Seefurth, and Kaumana

Phytotoxicity trials were conducted from 3 May to 6 July 1991 on anthuriums growing in volcanic cinder under 80% polypropylene shade. Each plot consisted of 18 matured flowering plants. Five weekly applications of Tame 2.4EC (CC17228), 0.4 lb (AI)/100 gal were applied until runoff (ca. 250 gpa) using a compressed air sprayer with a 8004 Teejet nozzle at 40 psi. Water was sprayed in control plots. Plants were observed weekly for phytotoxicity continuing for 5 weeks after the last application.
Tame 2.4EC was nonphytotoxic to the foliage or flowers of treated anthurium plants.
