Got an e-mail tonight that Entrust (spinosad) is going to be applied in the next few days to a potato field next to where I have bees on an organic farm. The farm manager tells me that Entrust is permitted under their organic certification and that they use it annually on their potatoes to control Colorado Potato Beetle grubs. The potato field this year happens to be less than 50 feet away from my bees.
According to the Entrust label - Entrust is toxic to bees for up to three hours after the application. Screening the bees so that they aren't in the potato field is easy enough (darn those attractive weeds!) - Is there anything I should do to help the hives avoid damage from drift? Pulling the bees from the yard completely could be done but is an option I would hope to pursue only as a last resort.
I am working with a new farm manager this year and so far things are cordial - I'd like to keep it that way.
