We would like to acknowledge the training and advice received from the
Barbara Sharanowski lab at the University of Central Florida and much
behind-the-scenes support from Tactica Interactive and the U of MB Plant
Science greenhouse and office staff.
Thanks to everyone who brought in weeds to identify or helped test the
grass key; to Jordan Bannerman who assisted with photography training,
and to Aldo Rios, who illustrated key characters and lent moral and
photographic support. Illustrations were supported by the University of
Manitoba Faculty of Agriculture Endowment Fund.
Special thanks all of our beta-testers and to the Mobile-IPM team, especially
Ana Dal Molin, for her continued input and guidance.
• Interactive, polyclave (multiple-entry) keys were developed using
Lucid Builder 3.3, exported using the open Structured Descriptive

• The species included were based on regional crop weed lists.
• Research was conducted on taxonomic descriptions of each weed.
• Species were grown from seed or observed in the field and
photographed at each life stage.
• A fact sheet was prepared for each species that lists all
characteristics and includes photos of all life stages

Grass and broadleaf identification keys are being developed as part of a free mobile application (Mobile-IPM) by the University of Manitoba.
Mobile-IPM is designed to help Canadian farmers identify pests, and implement effective integrated pest management strategies. Components include:
This poster focuses on the
Weed identification tool.
The Weed ID tool consists of 2 keys:
-Grassy weeds (grasses, sedges and rushes) – available online and to be tested in real time, using your cell phone
-Broadleaf weeds – in development
Mobile-IPM’s weed ID tool will allow users to :
-Identify the 200 most common weeds of cropland in Western Canada (MB, SK and AB)
-Use a mobile phone to identify a weed while in the field, or with a sample in hand.
-Identify weeds at any life stage (seedling, juvenile, maturity)
