Find Ways to Improve Profitability: Attend a Clinic

Bob Pomerleau
Make room on your calendar this winter for an opportunity to improve your operation’s profitability. WinField United retailers will be hosting more than 3,500 clinics across the country to share agronomic insights to help you get more from your acres, as well as highlight the latest plant nutrition and crop protection products. Here are some of the topics that may be presented at a clinic near you.
 
Response to Fungicide (RTF)
  • Learn about tools to help you understand where fungicide applications are more likely to have a positive impact on ROI.
  • See spray demonstrations to learn what products can help improve fungicide coverage.
Managing Dicamba
  • Determine the best practices for managing dicamba applications on Roundup Ready 2 Xtend® soybean acres.
  • Discover ways to combat herbicide-resistant weeds and steward new technology.
Journey of the Droplet
  • Get the facts. Picking the right adjuvant is extremely important in the battle against weed pressure and resistance. Learn more about how to improve coverage and uptake to get it right the first time.
  • Learn which adjuvants provide consistent product performance to help control rising pressure from weeds  
Tips for High Yield/High Management Acres
  • Prep for optimal yields by learning how to adjust nutrient levels throughout the year.
  • Learn how different nutrient formulations can influence plant uptake.
Nitrogen Management Best Practices
  • Find out how your fields are losing nitrogen and focus on solutions to keep it in the root zone.
  • Protect your investment by learning how the right rate, nutrient source and application timing can make a difference in plant availability. 
 
You’ll hear about these topics and more at the upcoming clinics. Our local agronomists will also be available to answer more specific crop production questions and provide recommendations as you plan for 2019. Contact your local WinField United retailer for more information about upcoming clinics in your area.

Wind Tunnel Will Enhance University of Minnesota Research

Dan Bissell
Senior Research Engineer, Product Development
A donation from WinField United will enable aerosol researchers at the University of Minnesota College of Science and Engineering (CSE) to study what’s blowin’ in the wind. And then use that knowledge to help farmers.
 
A large wind tunnel once housed at the former WinField United Product Development Center in River Falls, Wisconsin, is now ready to rev up at the Aerosol Diagnostics Laboratory on the university’s Minneapolis campus. The tunnel will be formally presented at a ceremony on November 16.
 
The tunnel played a major role in our breakthrough product research for many years. However, the new WinField United Innovation Center (opened in 2017) required an upgraded wind tunnel designed for the high throughput demanded by our product development process. This prompted us to see if the University of Minnesota was interested in acquiring our existing wind tunnel and using it for agricultural product research.
 
As a graduate of the CSE and having served as an undergraduate research assistant in the aerosol research department, I realized how beneficial this technology will be. 
 
Using aerosol research to fuel ag progress
The aerosol research group of the Department of Mechanical Engineering, founded in the 1950s, is one of the leading centers of small-particle research in the United States. Aerosol research is the study of how particulate matter moves through the air. Our work, which uses active ingredients with various spray nozzles and in multiple tank mixes, has enabled WinField United to develop considerable expertise in understanding the potential for spray drift of agricultural products.
 
Research at the Aerosol Diagnostics Laboratory will help validate and inform our activities at the Innovation Center and vice versa. WinField United and the University of Minnesota will collaborate and share learnings, and expand knowledge about spray drift in the agricultural industry.
 
One area of specific exploration may be dicamba drift. At WinField United, we’ve already begun to examine this issue and the use of drift reduction agents. This new partnership gives us another avenue to help tackle this problem. Examining droplet size more closely might be one way to begin to offer some answers to dicamba drift.
 
Pursuing the unexpected
WinField United sought out the CSE to make a connection with a discipline of science that is distinct from agriculture. We wanted partner with the experts on spray drift and particulate movement in the atmosphere.
 
There are numerous scientific disciplines in the CSE that WinField United could tap into. These include soil health, residual effects of herbicides, movement of pesticides through the soil layer and runoff of crop protection products into waterways. This partnership is a way for our company to bring more subject matter experts into agriculture to offer fresh perspectives on making our industry better for farmers and more sustainable for everyone.
 

Testing the Future of Spray Technology

The Skinny on Pump Shear and Dicamba Drift

Dan Bissell
Senior Research Engineer, Product Development
Last season brought headlines of farmers who faced challenges when they applied a new dicamba herbicide to their field — as well as to some who did not. More often than not, inadvertent dicamba drift was publicized to be the main culprit for damaged crops and bad feelings between neighbors.
 
At WinField United, we heard the stories. And we have a solution to help limit dicamba drift, giving you greater peace of mind.
 
If you have planted dicamba-tolerant soybeans or cotton this year, using a superior drift reduction adjuvant (DRA) is key to keeping your dicamba applications on target. However, not all DRAs are created equal. Some can break down in the spray tank due to shear in the pump. This renders them largely ineffective.
 
Finding answers
As part of our rigorous WinField® United Product Development Process, we evaluated several DRAs with new dicamba herbicide tank mixes using the WinField® United Spray Analysis System. In our lab-scale testing, some DRAs lost their ability to reduce driftable droplets due to the high shear environment of the pump simulation.1
 
But our testing also revealed a promising opportunity.
 
We found that OnTarget™ adjuvant was more resistant to shear breakdown, maintaining its drift-reduction technology, even after 50 passes through a sprayer pump simulation.

The pump shear problem
All DRAs start out by decreasing drift when mixed with dicamba. But some may not sustain that performance over time because they are subjected to shear forces in the pump, which occurs when some liquid moves faster than neighboring elements. The theory is that shear force causes the polymers in some DRAs to break apart, diminishing drift control.
 
OnTarget is formulated to be compatible with extra- and ultra-coarse nozzles and dicamba-based tank mixes, and its anti-foam formulation makes application convenient.
 
Adding OnTarget to the tank can give you more confidence about your spray outcomes. Make sure you’re getting the most out of your herbicide investment by reducing drift, enhancing droplet spreading and improving canopy penetration. Talk with your trusted local advisor about how OnTarget can work for your dicamba-tolerant crops this year.
