The Ontario Beekeepers Association is cautioning members about a smartphone app from CropLife Canada.
The OBA says the Bee Connected app could create a false sense of security.
The app is a partnership of CropLife Canada and the Canadian Honey Council.
If beekeepers register the location of their hives within 5 kilometers of a registered farmers property, both parties will be notified.
They can exchange further details using a secure messaging system.
CropLife says the app allows farmers to alert beekeepers to the application of neonics.
OBA President Tibor Szabo argues bees regularly forage as far as five kilometers from the hive and it's impossible for beekeepers to avoid all the various routes of exposure.
He suggests the best option is for farmers to stop using neonics to prevent pests Szabo says may not even exist in their soils.
