    Wood Wide Web - Healthy Root/Health Trees: Toso Bozic
    Wood Wide Web - Healthy Root/Health Trees: Toso Bozic
    Recent studies indicate that trees communicate with each other through a vast network of root systems, referred to informally as the "Wood-Wide Web". This presentation will examine the relationship of sail and tree roots and highlight potential damages that may result from tree root injuries and environmental causes. Knowing and understanding where tree roots are located, how they grow and interact, and how to manage their health, is crucial for the overall survival and thriving of trees.

    Recent Advances in Sprayer Technology: Tom Wolf
    Recent Advances in Sprayer Technology: Tom Wolf
    The past few years have seen an explosion of innovation in three specific areas. First is new nozzle technology. Ultra Course dicamba nozzles, nozzles for Pulse Width Modulation, and Twin Nozzles are most important and can assist operators with improved spray targeting. Seocnd is more efficient sprayer boom plumbing to prevent water and pesticide waste during priming and cleaning. And third is the rise of optical spot spraying in which sensors identify plants so that bare areas are not sprayed. All these technologies are commercially available or simple to implement. Put together, these changes can improve the speed, stewardship, and cost efficiency of any spray operation.

    New Herbicides: Continuous Improvement: David Pinzon
    New Herbicides: Continuous Improvement: David Pinzon
    This presentation will cover the general steps and aspects considered during the discovery of new herbicides. We will use Rinskor Active, a new active ingredient from Corteva Agriscience, to show the attributes considered for the development of new herbicides, and the benefits that new innovations represent to sustainability goals.

    Rinskor active is currently being assessed for registration under the Pest Control Products Act. It cannot be manufactured, imported, distributed, or used in Canada at this time, unless explicit authorization has been obtained from Health Canada to use this product for the purpose of conducting research under the Pest Control Products Regulations.
