Verimark is the soil-applied formulation of the control, while Exirel is foliar applied. Both use DuPont’s Cyazypyr, which provides cross-spectrum control of sucking and chewing pests like thrips, whiteflies and psyllids, according to a news release.
For citrus, Exirel applied in field trials at four Florida groves increased yield an average of 13.7% over the grower standard insect control program, according to DuPont.
Applied to fresh market Florida tomatoes in Immokalee, Myakka City, Parrish and Vero Beach, Verimark provided an average 15% yield increase 60% of the time, a 2012 DuPont trial found. Similarly, shank applications of Verimark on cantaloupes in Yuma, Ariz., provided 45% to 66% higher yield.
In Chula, Ga., cucurbits, Verimark tray drench application on Yellow Pride squash provided higher average yield per acre at three harvests: 300 pounds in one, and 1,500 and 2,000 in the others.
Products with Cyazypyr also have been registered by the EPA under its Reduced Risk Pesticide Program for all labeled crops.
