Since 1996 IR-4 has completed 259 trials with products containing sulfentrazone (Sulfentrazone 0.2G and Dismiss 4F) on 111 crops. The data contained in this report was generated to register uses of sulfentrazone on and around environmental horticulture plants with over-the-top applications. The sulfentrazone rates in the testing programs were 0.125, 0.25 and 0.5 pounds active ingredient per acre (lb ai per A) as the 1X, 2X and 4X rates. Sulfentrazone 0.2G had been applied to 54 plant genera or species. Of these, 12 exhibited no or minimal transient injury after application at all three rates. One crop exhibited no phytotoxicity at 0.125 and 0.25 lb ai per acre but did have some injury at 0.5 lb ai per acre. Only 3 crops (Canna sp., Echinacea purpurea, and Hosta sp.) exhibited phytotoxicity at even the lowest rate. Dismiss 4F has been applied to 65 crops since 1996. Of these only 6 (Buxus sp., Ilex vomitoria ‘nana’, Juniperus horizontalis, Rosa sp., Taxus sp., and Thuja sp.) exhibited no damage with over the top applications at all tested rates. Seven crops had minimal, transitory damage at the lower rates but some phytotoxicity at the 4X rate and 15 crops exhibited damage at all tested rates.
