CEU: [PM= 1.5]

Instructors: Dr. Jeff Gunsolus and Tom Hoverstad, University of Minnesota

·    Learn how different herbicides work and relate their site of action to their respective crop injury symptoms.

·    Learn to relate herbicide trade names to their respective site(s) of action.

·    Gain a better understanding of crop sensitivity to commonly used herbicides.

Corn, Soybean and Wheat Growth, Development, and Agronomics
CEU [CM=1.5]

Instructors: Dr. Jeff Coulter, Dr. Seth Naeve and Dr. Jochum Wiersma, University of Minnesota

·    Improve your understanding of corn, soybean and wheat growth and development; and how this affects the response of these crops to stresses and agronomic management.

·    Participants will evaluate corn, soybeans and wheat plants and demonstration plots at various growth stages with weather-simulated and agronomic stresses, provide biologically-based predictions of crop response, and provide agronomic recommendations.

·    Participants will gain the knowledge to stage corn, soybean and wheat plants to understand the importance of all growth stages relative to weather stresses and their impact on yield.

Pesticide Resistance Management and IPM Scouting
CEU [PM=1.5]

Instructors: Dr. Robert Koch and Dr. Madeleine Smith, University of Minnesota

This two-part session will focus on pest resistance to pesticides and scouting for pests. In the first part, participants will learn how and why pests develop resistance to insecticides and fungicides; how to postpone or prevent development of resistance; how to identify potential cases of resistance in the field; and how university staff monitors for resistance. In the second part, participants will learn how to accurately estimate disease severity and percentage defoliation, to aid in scouting and pest management decisions. Activities and demonstrations will be used to reinforce the concepts.

Corn Rootworm Scouting and Trait Management
CEU [PM=1.5]
Instructor: Dr. Ken Ostlie, University of Minnesota

Corn grower concerns are increasing over the issues surrounding transgenic failures from corn rootworm resistance. This session will focus on the missing ingredient in management decisions: field-specific intel and its implications. Field-specific Info is critical to determine if you're facing resistance, its magnitude of threat, and the best management strategy for your corn rootworm problems. Learn how to scout corn rootworms and evaluate root injury. See the consequences of resistance first hand. Discuss what this information means for managing corn rootworm and prospective resistance, the current resistance situation, and the implications of disrupted rotations and delayed planting on the corn rootworm threat for 2014.

SECOND DAY SESSION DETAILS Participants will be able to select up to six of the ten, one-hour sessions; each session provides one continuing education unit (CEU).

Root Diseases and Root Health for Soybean and Corn
CEU: [PM= 1]
Instructors: Dr. Dean Malvick, University of Minnesota

Root health and root diseases have large impacts on crop growth and productivity, and this session will enable participants to more fully understand different types of root diseases, how they damage roots, how to diagnose root diseases, and how to manage them. Following a discussion and demonstration period, the participants will be asked to look at 'unknown' samples and practice their abilities to diagnose the problem. This session will be conducted in a classroom and teaching lab facility on St. Paul Campus.

Principles of Weed Seedling Identification
CEU: [PM= 1]
Instructors: Dr. Bev Durgan and Lisa Behnken, University of Minnesota

Even in today's world of glyphosate resistant crops it is important that Ag professionals retain the ability to correctly identify common weed seedlings. This session is designed to acquaint the learner with the skills and references needed to identify seedling broadleaf and grass weeds. Live plant seedlings and established weeds from the University of Minnesota-St. Paul Campus weed garden will be used in this hands-on session.

Evaluation and Management of Corn in Water-Limiting Environments
CEU [CM=1]
Instructor: Dr. Jeff Coulter, University of Minnesota

Since the 1920s, corn yield in Minnesota has increased at about two bushels per acre per year due to improved varieties and agronomics. This hands-on session will allow participants to:

·    Understand corn response to drought stress, and how this is affected by growth stage, nitrogen fertility, and plant population.

·    Participants will evaluate corn plants and demonstration plots under drought stress with contrasting levels of nitrogen fertility and plant population, provide biologically-based predictions of crop response, and provide agronomic recommendations.

·    Knowledge obtained from this session will help participants more accurately predict corn response to water limitation, enabling them to make improved agronomic decisions when drought stress is anticipated or when irrigation water is in limited supply.

Plant tissue sampling: what to sample and when to sample
CEU [NM=1]
Instructors: Dr. Dan Kaiser and Jeff Vetsch, University of Minnesota

·    The objective of this topic will be to demonstrate typical sample collection times and plant material to sample for crops common to the area. Participants should know why it is important to sample at the appropriate time for the appropriate plant part and understand possible sources of errors to avoid when taking samples.

·    Participants will be asked to sample corn and soybean plots using their current knowledge. Using data analyzed prior to the activity, the sampling will be followed up by a discussion using the lab data on differences and possible effects due to differences in how the samples were taken.

·    With the large number of samples being taken on a yearly basis, this topic will aid in the participants in making sampling plans and to better understand the validity of tissue analysis data obtained from the field.

Remote sensing: old standbys and new possibilities
CEU [NM=1]
Instructors: Dr. Dan Kaiser and Jeff Vetsch, University of Minnesota

·    The objective of this topic will be to give participants hands on learning with currently available remote sensing tools and to demonstrate new possibilities on the horizon. Areas of emphasis will be what is actually measured with each tool, what they can be used for, and what the limitations are.

·    Field demos will be established utilizing hybrid differences, planting dates, and fertility differences to demonstrate how these factors affect results from the tools currently available. Participants will have the opportunity to use some of the tools available to scan the crop and differences detected by the participants will be discussed.

·    There is an increasing emphasis for the use of active scanners in developing nutrient management plans specific to nitrogen. However, many of the tools available do not necessarily measure what is needed in order to make them useful in the field. By the end of the session participants should know what each tool measures and the limitations of each for use in making nutrient management decisions. This knowledge will help to make decisions for themselves or customers on what to use and how to use it.

Scouting and thresholds for soybean insects:
CEU [PM=1]
Instructor: Dr. Robert Koch, University of Minnesota

·    Participants will learn and practice scouting techniques for soybean aphids, defoliators and natural enemies. Scouting techniques will include whole-plant counts, sweep-net sampling and defoliation estimation. Stink bugs and Japanese beetles will also be reviewed as emerging soybean pests.

·    Participants will also estimate defoliation on caged and open field plants and use sweep net sampling to scout for defoliators.

·    Participants will be able to apply this knowledge of scouting techniques, pest identification and thresholds to improve IPM decision making. Use of scouting and thresholds for management decisions should aid in preventing or delaying the development of pest resistance to insecticides.

Soybean stresses: What you see and what you don't
CEU [SW=1]
Instructor: Dr. Seth Naeve and Jodi DeJong-Hughes , University of Minnesota

·    Participants will be better able to evaluate effects of less obvious stresses that primarily affect the belowground portion of the soybean plant. Participants will have an increased understanding and knowledge of soil compaction effects and waterlogging effects on soybean root and aboveground vegetative growth.

·    Participants will be asked to 1) evaluate relative plant health based on their normal/regular/routine methods (evaluate aboveground plant vigor, biomass, greenness), 2) Evaluate these same factors utilizing canopy reflectance (NDVI), 3) Dig plants to evaluate roots visually, 4) evaluate roots digitally (WinRhizo), 5) evaluate soil structure with a soil compaction probe to investigate compaction effects on soybean root development

Rust Diseases in Wheat
CEU: [PM=1]
Instructors: Dr. Madeleine Smith and Dr. Jochum Wiersma, University of Minnesota

There are three rust diseases that occur on wheat: stem rust, leaf rust and stripe rust. These diseases are each caused by a particular species of the "rust" fungus, Puccinia. Rust fungi all produce similar disease symptoms on the host plants and have similar requirements for infection. At this session, students will observe and diagnose rust symptoms and will receive instruction in management tactics for the control of rust diseases in Minnesota.

Crop Diagnostics for corn, soybeans and wheat.
CEU [CM=1]
Instructors: Dave Nicolai, Ryan Miller and Dr. Jochum Wiersma, University of Minnesota

·    Practice problem recognition and interpretation utilizing small plots representing actual cropping systems.

·    Diagnosing common corn and soybean establishment problems; which final plant populations are acceptable to maintain in the event of crop damage.

·    Understanding corn, soybean and wheat growth staging and response to hail damage.

Preemergence Herbicide Strategies in Soybean
CEU: [PM= 1]
Instructor: Dr. Jeff Gunsolus, University of Minnesota

·    Participants will be presented with weed control results from several research locations addressing several common weed species. Participants will also evaluate the herbicide injury potential of timely and delayed preemergence herbicide application on various crop species.

·    We will evaluate five preemergence soybean herbicides to investigate crop injury potential and duration of weed control.

·    A better understanding of preemergence herbicides will improve the effectiveness of this weed management tactic, reduce crop injury potential and allow for a better integration of this tactic into herbicide resistant weed management.
