2016 Downy Mildew Control Strategy for Cucumber Crops

The 2016 Downy Mildew Control Strategy for Cucumber Crops contains an updated list of fungicides, including the newly registered Orondis Ultra. The restricted entry interval for Bravo has also been updated to reflect the new Bravo ZN label.

Due to the development of resistance and concerns about efficacy, Tattoo C and Presidio have been removed from the 2016 strategy. These products may provide  suppression under low risk conditions, however research results indicate that they are not sufficient controls under higher disease pressure.
