Tolfenpyrad was first registered as Hachi-Hachi 15 EC in the United States on July 28, 2010 for the control of aphids, leafhoppers, scales, thrips, whiteflies, and early instar lepidopteran larvae on environmental horticulture crops grown in greenhouses. A new formulation Hachi-Hachi 15 SC was registered on March 30, 2015, then on June 11, 2018. An expansion of this label for outdoor uses is planned. The IR-4 Project completed 194 trials on 29 ornamental plant species from 2010 through 2016 examining phytotoxicity related to foliar applications of Hachi-Hachi 15EC or Hachi-Hachi SC. In this report, 11 species or genera exhibited no or minimal injury after foliar treatments of Hachi-Hachi 15EC (tolfenpyrad) at 21, 48 and 84 fl oz per 100 gal. Three of these crops are already in the current label as crops tested for tolerance: Chrysanthemum/Dendranthemum sp., Petunia sp., and Tagetes sp. The rest can be added to the label: (Alyssum sp., Angelonia sp., Antirrhinum sp., Begonia sp., Dahlia sp., Verbena sp., Viola sp. and Zinnia sp.). For Hachi-Hachi SC, 20 species or genera exhibited no or minimal injury; 5 of these crops are already in the current label as crops tested for tolerance. Fifteen crops can be listed on the label (Angelonia sp., Bacopa sp., Begonia sp., Calibrachoa sp., Dracaena sp., Dahlia sp., Fuschia sp., Hydrangea sp., Lobularia maritima, Pelargonium x hortorum, Petunia sp., Rosa sp., Tagetes sp., Verbena sp. and Viola sp.).
