Wilmington, Delaware (June 1, 2017)—Torac® Insecticide from Nichino America, Inc. has been granted a Section 18 Crisis Emergency Exemption to control thrips in watermelon on the Island of Oahu in Hawaii, the company announced today. The extension allows use of Torac in watermelon until June 15, 2017.
Torac provides fast knockdown and control of thrips including melon thrips (Thrips palmi). The active ingredient in Torac, tolfenpyrad, works by blocking cellular respiration and is extremely effective on all stages of thrips: eggs, larvae, nymphs, 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 two applications per crop cycle at a 21 fl oz/acre rate. The label also states a 12-hour reentry interval (REI) and a 1-day preharvest interval (PHI).
Torac has been tested in University trials for several years with successful results in the control of thrips in cucurbits. Please refer to your local Nichino America sales or product development representative for more information.
