Mating Disruption for Navel Orangeworm

CheckMate® NOW-F

The first sprayable pheromone for navel orangeworm control

CheckMate® NOW-F is Suterra's pioneering sprayable pheromone formulation for navel orangeworm (NOW) mating disruption in nut crops, figs and other crops where the navel orangeworm is present.

The world's first sprayable pheromone option for NOW control, this product easily fits into growers' existing integrated pest management (IPM) program. It is tank mixable with common agrochemicals and works well with nearly any water volume. It can also be applied aerially.

CheckMate® NOW-F gives growers the flexibility to tailor the number of sprays each season depending on the timing and pressure of NOW flights in their fields.
