Spotted Wing Drosophila 2017
This year we are doing a very small scale regional monitoring program. Use these results in addition to your own monitoring program to determine when SWD is present. Conduct a salt water test or a plastic baggie test to confirm presence. The monitoring program is coordinated by the OBGA.
Michigan and New York are catching SWD. SWD has been caught earlier in Southwest Michigan than in previous years. Every year is different so check your fruit regularly to find the first SWD.

- SWD has been identified in a few traps in Ontario, in Essex, Kent, Wellington, Brant, Niagara, Norfolk, and Haldimand county.
- Check the SWD product registrations on our website. The Exirel label has been expanded to include SWD control on caneberries, and Mako and Malathion have received emergency use registration for this year again.
- When SWD is present in your crop use regular sprays, thorough, clean harvest, and immediate post-harvest cooling to less than 5C or cooler.

Can you advise us which of these products are certified organic?
Hi Phil,
Entrust is most likely available as an organic option but you will have to contact your certifying body to confirm.
