The pre-harvest interval of Delegate for the control of spotted wing drosophila on bushberries has been amended through a minor use label expansion. The pre-harvest interval has been reduced to 1 day for bushberries, with a 12 day retreatment interval. The updated registration page can be found here: SWD Registrations June 2019 V2.   

Erica Pate, Ontario fruit specialist for OMAFRA, has issued this notice.  Please update the chart printed on page 12 of the July issue of The Grower.  

Check the original post from June 21 for more recommendations on managing SWD, including regular harvest, immediate cooling post-harvest, and sanitation.
