INDIANAPOLIS — Field trials conducted by Cornell University in 2015 reinforce the effective control of Delegate® WG insecticide in combating troublesome pome fruit pests. Whether sprayed alone or tank-mixed, the study shows that Delegate provides consistent control of several fruit-damaging pests, including codling moth, Oriental fruit moth and lesser appleworm in apple orchards. The results confirm that the level of control of obliquebanded leafroller provided by Delegate classified it as one of the best treatments tested with virtually no injury to terminals and less than 2 percent pest-inflicted injury to fruit.   

“Delegate has been, and remains, one of our top tier products for use in seasonal insecticide treatment programs against the internal-feeding Lepidoptera, as well as obliquebanded leafroller,” says Arthur M. Agnello, professor, Department of Entomology, Cornell University. “In addition, because of its unique chemistry, the role of Delegate as a primary rotation partner is something that we feel is very valuable in insecticide resistance management programs.”

A related study conducted in 2015 by the New England Fruit Consultants further validates results from the Cornell trials. The study shows applications of Delegate® WG insecticide on pome fruit provided quick and effective control of obliquebanded leafrollers with little or no injury to terminals or fruit.

Northeast pome and stone fruit growers have come to rely on Delegate as the foundation insecticide for their pest control rotation programs. As a Group 5 insecticide, Delegate contains the innovative active ingredient spinetoram, a unique chemistry that makes it ideal for insecticide resistance management. The product’s minimal impact on beneficial insects also makes Delegate the perfect Integrated Pest Management (IPM) partner.

“In addition to reinforcing industry-leading control of damaging pome fruit pests, results from the trials also underscore the quick knockdown of Delegate,” says Kevin Sheaffer, insecticide product manager with Dow AgroSciences. “One application effectively controls multiple pests, saving growers time and improving the opportunity for profit.”

With a short four-hour re-entry interval (REI), Delegate also offers growers convenience and maximum management flexibility.
