What's the deal with Delia? Field Day

Posted by Stephanie Rogers on June 30, 2015 in News, Research

Join us on a field tour, July 9th 8:15 - noon to learn more about onion maggots (Delia antigua) and other Delia species that attack onions, corn, beans and Brassicas such as cabbage, broccoli, cauliflower, radishes, kale and Brussel sprouts.

AAFC is currently conducting research to determine which Delia species are present in Nova Scotian onion fields and to determine if surrounding vegetation or field history can influence Delia populations and subsequent damage.

Netting and floating row cover can be powerful tools to combat insect pests such as cabbage root maggot (Delia radicum).Perennia and AAFC are currently conducting research into the efficacy of different netting mesh sizes. A Wondermesh Netting/Row Cover Retriever will be on hand to demonstrate technology that makes using netting and row covers easier!

Carrot weevils (Listronotus oregonensis) are sporadic pests of carrots. Current AAFC studies are evaluating the carrot weevil’s movement within the field and identifying overwintering sites.

Coffee and muffins at 8:15 AM at Kentville Research Station - bus leaves at 8:30 AM sharp!
