Corn Virtual Field Day
September 9, 2020
Michigan State University (MSU) will host a Corn Virtual Field Day with emphasis on 2020 production issues including tar spot disease, field unevenness and integrated management on Wednesday, September 9 from 9 to 11 a.m.
The Corn Virtual Field Day will be moderated by Kristin Poley from the Corn Marketing Program of Michigan and will feature MSU Extension Specialists and Educators.
Despite not being held in-person, the organizers have developed an interactive and responsive program that will include video, conversation and Q&A.
The first half of the event will focus on tar spot in corn. “Tar spot is a recently introduced disease to Michigan and we are still learning a lot about it and how best to manage it,” says MSU Extension field crops pathologist Marty Chilvers. “The 2018 season saw some fields experience losses on the order of 50 bushels per acre due to this disease. The 2019 season was drier in July and August so losses were far less severe; however, the pathogen continued to spread and can now be found across the lower half of Michigan.”
The second half of the morning will focus on uneven corn development within a field with a panel of MSU Extension Field Crops Specialists. Among those presenting will be Weed Specialist Erin Burns and Cropping Systems Agronomist Manni Singh. “Understanding how early season weed control decisions impact season-long success is a critical component to corn production,” says Burns who will share resources about weed control research in corn conducted by the MSU Weed Science Program. “Variability early in the season can impact pollination success, and there are many agronomic factors affecting that variability,” says Singh who will discuss management decisions that drive some of those factors.
Features of the day will include:
- Latest on tar spot research including fungicide efficacy and timing trials, effect of plant population and fertility.
- How to scout for tar spot and some thoughts on fungicide spray thresholds.
- Information on tar spot variety resistance screening and yield loss.
- Use of leaf wetness sensors to predict the potential risk of plant disease
- Discussion on causes of uneven corn development related to weed control, nutrient management, pest control, and agronomic management.
- Live Question and Answer session with all speakers.
This session has qualified for 2 Restricted Use Pesticide (RUP) credits (Private/Commercial Core, Field Crops 1A) and Certified Crop Advisor (CCA) Credits in the areas of Integrated Pest Management for 15. Credits and Crop Management for 0.5.
