Seedling Barnyard grass Juvenile Barnyard grass Mature Barnyard grass 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 Data (SDD 1.1) standard and made public through a customized application interface. • 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 A new tool for grass and broadleaf identification on cropland in Western Canada Jo-Anne Joyce, Doug Cattani, Rob Gulden| Dept. of Plant Science| University of Manitoba, Winnipeg, MB R3T 2N2 Email: [email protected] 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) An interactive identification tool for crop pests (insects, weeds & disease) A real-time pest monitoring and forecasting tool A crop management tool Methods Weed ID Beta-test Procedure Acknowledgements Project Overview Weedy Grasses of Cropland in Western Canada is available for beta- testing at: https://ipm- devl.ad.umanitoba.ca/identify . Live plant material is available to identify during the poster viewing so you may test the Weed ID tool using your phone. Start by loading the app via SQ or URL. Choose ‘Pest Identification Pest identification What’s an auricle? Click on the Help button (?) for a definition. Next, choose a part of the plant to focus on. In this example, we’ve chosen ‘Base of Leaf’. This is a good set of characters to start with when identifying grasses. Choose ‘Weedy Grasses of Cropland in Western Canada’ The more features you identify, the more precise the results become. Notice the number of options in the top right- hand corner has decreased. Click on that number to access species matches. Your plant lacks auricles and ligules, the stem is smooth and compressed. Your grass doesn’t appear to have auricles, but you check the options anyway. You check the illustrations, and reaffirm that your plant lacks auricles. You choose ‘Auricles absent’. Notice the number at the top right corner of the screen. It indicates the total number of species in the key. Your plant is probably Barnyard grass. Check the photo, and click on ‘Details’ to make sure all the characters fit. If the result is not a good fit for your plant, you may check other close matches, submit a photo, or press the ‘Feedback’ button to send an email to the first author.
