Spotted Wing Drosophila Update #1

Thursday, July 26, 2018

Spotted wing Drosophila have been found from monitoring being done in Nova Scotia. The first female was identified from traps in an unmanaged highbush blueberry plot. If you have not already began trapping and plan to do so, you should be putting out traps as soon as possible. 

The spotted wing Drosophilia is a critical pest because unlike most Drosophila species the spotted wing Drosophila infests ripe fruit, instead of rotting fruit. The fly causes damage by laying its egg in ripening fruit, where the larvae hatches and begins to feed. As the larvae feeds the fruit deteriorates rapidly, causing the fruit to become unmarketable. Because of this spotted wing Drosophila infestations can result in significant crop losses making monitoring and proper timing of controls crucial. The spotted wing Drosophila is a serious pest in many soft fruits, including: wild blueberries, highbush blueberries, strawberries (Day neutral and June bearing), raspberries, blackberries, cherries, peaches, plums, gooseberries, currants, grapes and a wide variety of wild and native fruits.

For more information on monitoring and control options please refer to Perennia's Raspberry Insect & Disease Management Schedule 2018 and factsheet on Monitoring for Spotted Wing Drosophila.

New Product Registrations - March 2018

Monday, April 16, 2018

Agri-Réseau is a resource available through The Centre de référence en agriculture et agroalimentaire du Québec (CRAAQ).  Every month, they publish a list of new phytoprotection registrations.  At Perennia, we are fortunate to have Mélanie Leclerc as part of our staff, and she has translated the March list of new pesticide registrations for Fruit Trees, Field Crops, Vegetables, Greenhouse, Berries, Ornamental, and"Other" (hops, hemp, quinoa, and basil), which can be found here.

For caneberries, the main excitement lies in the registration of Indaziflam for weed control and Oxathiapiprolin for control of phytophthera sp. root rot.  To see more details on the products please click the link above.

I would just like to highlight that several of these products have been registered as a direct result of the Minor Use Priority Setting process.  Perennia holds regional grower consultations every November/ December that allow NS growers to have a voice in the National selection process. For example, Oxathiapiprolin was selected as a national priority in 2012 and we have now received registration!  Your voice counts!

PMRA consultation on Thiamethoxam (Actara 25WG) and Clothianidin (Clutch 50WDG)

Wednesday, January 3, 2018

On December 19, 2017 PMRA announced a re-evaluation of and opened consultations on the neonicotinoid pesticides - Thiamethoxam (Actara 25WG) and Clothianidin (Clutch 50WDG) citing concerns about the effects of neonicotinoid pesticides on bees and other pollinators.

These consultations are open for comment from 19 December 2017 to 19 March 2018 (90 calendar days).  Comments can be provided to PMRA at:

In summary, the following mitigation measures are being proposed respecting Thiamethoxam (Actara 25WG) use in berries on weevils:

          Remove pre-bloom foliar use
          Maintain post-bloom foliar use with renovation after harvest 
          Remove soil use
Bushberry (incl. highbush blueberry) and Caneberry (incl. raspberry and blackberry)
          Remove pre-bloom and during bloom foliar use
          Maintain post-bloom application

Other crops will also be effected by this re-evaluation.  Complete information on the re-evaluation consultation is available at:
