TABLE OF CONTENTS

Springtime at the STSC

2017 has been a year of extremes for trees and those of us that care for them. Southeast Minnesota broke a weather record for rainfall. Northwest Minnesota struggled through a summer of wind and drought. Buckets of snow came early for Northeast Minnesota and many of us that grow and plant trees long for that record-breaking growing season of 2016 when we were planting trees into December.It’s been an active year of bugs and crud, too. Emerald ash borer has shifted into overdrive and many communities are struggling with the loss of canopy and the expenses of removals, treatments, and replacements. Japanese beetles dominated the questions posed by homeowners with tree questions at the State Fair. It seems like something is bothering bur oaks and pines everywhere and magnolia scale, Ips bark beetles, and hickory blight are becoming way too familiar to arborists and homeowners. For those who like to fret, 2017 has been a very generous year. However…2018 is looking great so far! Tree nurseries are building up their stock selections and numbers again after the slow years of the

recession. More “new” native trees to the upper Midwest are becoming available. More communities are incorporating engineered “soils” in their sidewalk and plaza planting areas, and community gravel beds are becoming more common planting options. Minnesotans are not afraid to take a chance with new ideas to manage healthier landscapes, new plant materials, and new technologies to help us work more efficiently and safer.So that’s our goal this year at the 56th annual Minnesota Shade Tree Short Course: to help you take those chances and come out smelling like a rose (or a lilac or a basswood). To make this the best Short Course ever, we have some of your favorite speakers returning, many of the best experts Minnesota has to offer, and a host of other national and international experts. They’re all gathering here for you and to make 2018 your best year ever.Join us, whether for the first time or the 56th. The Minnesota Shade Tree Short Course is the perfect spring tonic for those of us who believe photosynthesis is the most beautiful word in the English language. Catch up with old friends, make some new ones; bring a guest. The weather is always perfect when it’s springtime at the STSC.

IT’S MORE THAN JUST A JOB.

What do we mean by “Tracks?” A track is both a level of detail or depth of the topic as well as which professions would benefit most from the session. An Introductory Track is delivered at a level that most audiences can readily understand and is considered a basic, more general session. These sessions are meant for either those who are new to the profession or science of urban forestry or are looking for a refresher course.

A Technical Track contains information that builds on a basic knowledge of a subject or is on a very specific topic, for instance, a session on a particular disease and all of the details of that plant disease as opposed to a general session on leaf problems of deciduous trees.An Advance Track contains the most detailed and specific information on a topic and is intended for those who have had a lot of experience and/or education on that specific topic. This track builds on that previous experience and educational level.A Community Track consists of sessions that are particularly useful for urban foresters who work with communities, community groups, volunteers, and decision-makers who don’t have a background in urban forestry.A Certified Arborist Track has sessions that we know will help someone either prepare for taking the CA exam or prepare for an advanced CA specialty, such as Municipal Specialist.A Commercial Arboriculture Track is designed for the practicing arborist: private, corporate or campus arboriculture, consulting arborists, tree inventory and management plan specialists, tree health care professionals.

The Municipal Forestry Track includes sessions that are probably the broadest in nature since municipal foresters must address the biological, social, and political issues of urban forestry.The Tree Inspector Track recommends those sessions that should be most useful for those attending the STSC to become recertified. This is the largest group of sessions primarily because of the diversity of Tree Inspector responsibilities around the state. Customize your two-day plan so it will help you the most in your community.The Utility Arboriculture Track is the most deceptive track because it implies that it’s for utility arborists only! Not so! These sessions benefit all of us by helping us understand the responsibilities and challenges of managing vegetation in utility corridors. If you’re torn between a couple of sessions and one is a utility session, choose the utility session if you really want some new information.

SESSION DESCRIPTIONS

GENERAL SESSSIONSCallus, Woundwood, Decay and Plant Health CareChristopher Luley, President/Pathologist, Urban Forest Diagnostics LLC

Assessment of callus and woundwood are critical to evaluating tree resistance to pests and pathogens. Wound response is also directly tied to the ability of trees to contain decay fungi both before and after infection. Learn how to identify the various wound responses of trees what they mean for pest resistance.

Drift Away: Diagnosing Drift and Carry-Over Injury in TreesHannah Mathers, Independent Researcher/Consultant, Mathers Environmental Science Services, Inc .

More genetically modified crops (GMCs) are being used in agriculture than ever before, with stacked glyphosate- and dicamba-resistant soybeans and Xtend™ seed being some of the most recent players. Additionally, the lines between urban and rural have been blurring for years and, consequently, herbicide drift and carry-over injury on “nontarget” crops, including nursery and landscape, have escalated. Carry-over in the plant and in the soil, as well as how to diagnose the variable nature of drift, will be presented with real-life cases. You won’t “get lost in the rock and roll”—but you will see why some herbicide applications, unfortunately, just “drift away.”

Electric and Arboricultural SafetyRandall H. Miller, Director of Research, Development, and Industry Intelligence, CNUC

Electric contact is a frequent cause of arboricultural workplace fatalities, and no job is worth injury or loss of life. This presentation will enable attendees to explain some electrical fundamentals, characterize electrical risks, detail electrical safety precautions, differentiate between safety and incident prevention, and understand how to develop a culture of incident prevention.

Planting in a Post-Wild WorldClaudia West, MLA, Phyto Studio

We live in a global city and few wild places remain in today’s world. Planting designers have the opportunity and responsibility to bring wildness and ecological value back into our landscape. This challenge requires a new form of planting design that works with natural principles and marries horticulture with ecology. Join us as we explore how native and ecological plants will fit into our future landscape and how plant community-based design strategies can help you meet aesthetic and ecological goals during your next planting project.

The Use of Biologicals: Their Potential for Improving Tree Health and Managing Pests and DiseasesGlynn Percival, Bartlett Tree Research Laboratory UK/Ireland

Microorganisms have been waging war against each other more or less since the dawn of life itself. Consequently, we can use these “biologicals,” or plant-friendly microorganisms, to

“fight fire with fire.” For example, microorganisms can play important roles in enhancing plant defense responses and can be manipulated as a form of direct and indirect biological control. Whilst synthetic fungicides and insecticides can have impressive and rapid effects, the use of biologicals utilizes a more complex, subtle, and long-term strategy. This talk aims to discuss the potential of commercially available biocontrol organisms for the benefit of arborists with respect to disease control strategies, as well as highlighting ongoing research programs undertaken at the Bartlett Tree Research Laboratory.

Whose Tree Is It Anyway? Boundary Trees and Property Line DisputesBryan Zlimen, Attorney, Zlimen & McGuiness PLLC

Overhanging branches, fallen limbs, and other cross-boundary issues can cause disputes for your customers and challenges for your crews.

Dormant Applications in Landscape Beds? Why They Make SenseHannah Mathers, Independent Researcher/Consultant, Mathers Environmental Science Services, Inc .

Dormant applications can reduce phytotoxicity and increase the duration of efficacy of many of your herbicides. Three additional benefits of dormant applications will be discussed: 1) utilization of staff in winter, which is traditionally a “down-time” labor-wise versus spring; 2) insurance that applications will be completed before weed germination, versus waiting for spring when conflicting operations take precedence; and 3) optimized control of weeds that are active in cold weather: problematic perennial and biennial weeds.

Enhancing Tree Immune Systems by the Use of Soil Amendments: A New Potential Management Strategy for Pests and DiseasesGlynn Percival, Bartlett Tree Research Laboratory UK/Ireland

Control of tree diseases is done primarily through the use of synthetic agrochemicals. Increased legislative restrictions regarding the use and application of agrochemicals mean new techniques of disease control are now of fundamental importance. Trees can defend themselves against pathogen infection through a wide variety of mechanisms that can be local, constitutive, or inducible. Developments in plant protection technology have led to the formulation of several soil amendments that induce or “switch on” a plant’s own defence mechanisms. These include chitin, phosphites, biochar (a form of activated charcoal), and pure mulches, i.e., a mulch made from a single tree species. Preliminary studies show a single soil application of these amendments provides long-lasting, broad spectrum control of several fungal, bacterial and viral pathogens. Importantly these amendments act by organic means and so are not subject to government legislative restrictions. The aims of this presentation are to discuss the efficacy of a range of soil amendments on controlling apple scab (Venturia inaequalis) and Phytophthora root rot.


We will discuss common and unusual plants that produce edible fruit but can also be grown for ornamental value. Diseases and other potentially limiting problems for each species will be included.
