Research Summary Abstract
From 2010 to 2013, IR-4 completed 24 trials on Racer (Ammonium nonanoate). The data contained in this report was generated to register uses of active ingredient on and around ornamental horticulture plants with broadcast applications, including over the top of established plants. The Racer rates in this testing program were at 3 and 6 % v/v as the 1X and 2X rates. It had been applied to 16 plant genera or species. Results showed Racer causing no injury when applied to these crops in the dormant stage of growth. Of these genera and species, none exhibited no or minimal transient injury after the second application at both rates. Four (4) crops showed significant injury after the second application. Of the twelve (12) crops that still need additional information, there are six (6) genera or species in which one or two trials did not show significant injury at 1X and 2X rates.
