DuPont’s Verimark And Exirel Insecticides Receive EPA Approval
January 30, 2014 DuPont’s Verimark and Exirel insect control products have received federal registration and, according to the company, each product offers new technology to help protect crops against damaging insects and pest-vectored diseases that threaten the U.S. produce industry.
“When used early in the crop life cycle, these products help protect a grower’s crop production investments and help deliver improved profitability and productivity,” said James Hay, regional business director, North America, DuPont Crop Protection. “Verimark and Exirel are the latest examples of how DuPont collaborates with specialty crop growers in the U.S. and around the world to bring solutions that improve their opportunity for higher yields and improved fruit and vegetable quality at harvest.”
DuPont Crop Protection products provide growers maximum flexibility and enable them to tailor integrated pest management (IPM) programs to meet their specific regional crop needs. Verimark is the soil-applied formulation, while Exirel is a foliar-applied product. Both are powered by Cyazypyr, a single active ingredient that provides a new mode of action for cross-spectrum control of sucking and chewing pests, including thrips, whiteflies, and psyllids.
When used early in the growing season for insect control, Verimark and Exirel help deliver improved crop quality and yield. For example:
• In mature/bearing citrus, Exirel applied at the spring and summer flush in large plot demonstration studies at four Florida grove locations, increased yield of total pounds of fruit by an average of 13.7% over the grower standard insect control program.

• When applied to fresh market tomatoes in Immokalee, Myakka, Parrish, and Vero Beach, FL, Verimark provided an average 15% yield increase 60% of the time. (Source: 2012, DuPont large plot replicated and demonstration field trials.)
• Shank applications of Verimark on cantaloupes in Yuma, AZ, provided 45% to 66% higher yield advantage. (Source: 2011, Yuma, AZ.)
• In Georgia cucurbits, Verimark tray drench application on Yellow Pride squash provided higher average yield at each of three harvests: 300 pounds per acre higher yield than the grower standard in the first harvest; 1,500 pounds per acre higher yield than the grower standard in the second harvest; 2,000 pounds per acre higher yield than the grower standard in the third harvest.

Products powered by Cyazypyr also have been registered by EPA under its Reduced Risk Pesticide Program for all labeled crops and have short worker reentry and preharvest intervals.
Verimark and Exirel are the latest advancements from DuPont Crop Protection. As the second active ingredient in the anthranilic diamide class of chemistry, Cyazypyr was discovered and developed by DuPont. The first active ingredient in the class was Rynaxypyr, which powers DuPont Altacor, Coragen, and Prevathon insect control, offering rapid, long-lasting control of damaging lepidopteran pests.
