United StatesTorac® Insecticide from Nichino America, Inc. has been granted an extension for a Section 18 Crisis Emergency Exemption in nine counties in the state of Texas to control thrips in dry bulb onion. This extension follows the crisis emergency exemption for Torac that was granted on March 17, 2017 and scheduled to expire March 31, 2017. The extension allows continued use of Torac in dry bulb onion until July 10, 2017, unless otherwise notified.
The counties in Texas where Torac is permitted for use under this Section 18 Crisis Emergency Exemption include Cameron, Dimmitt, Frio, Hidalgo, Maverick, Starr, Uvalde, Willacy, and Zavala.
Torac provides fast knockdown and control of thrips including onion thrips (Thrips tabaci) and western flower thrips (Frankliniella occidentalis).
The active ingredient in Torac, tolfenpyrad, works by blocking cellular respiration and is extremely effective on all motile stages of thrips: larvae, pupae, and adults. Torac causes rapid feeding cessation and control of thrips usually within 24 to 48 hours. Torac belongs to the METI (Mitochondrial Electron Transport Inhibitor) class of compounds, IRAC Group 21A Insecticide. For effective resistance management, Torac should be used in rotation with insecticides of different modes of action.
Torac is a contact, foliar insecticide which means that sufficient spray coverage is essential. Based on the label, growers can make three applications per year at a 24 fl oz/acre rate. The label also states a 12-hour reentry interval (REI) and a 7-day preharvest interval (PHI). Torac has been tested in University trials for several years with very successful results in the control of thrips in onions.
