WHAT'S NEW WITH BAYER CROPSCIENCE PRODUCTS
New herbicides are launched every year – offering growers improved agronomic packages for better
results. But what they don’t often offer is a new chemical mode of action. Awareness of the product’s mode of action, however, is critical when trying to keep herbicide resistance at bay.
“Growers don’t tend to think about proactively managing herbicide resistance because there isn’t any immediate impact on their crop by doing so,” says Neil Harker, a research scientist with Agriculture and Agri-Food Canada in Lacombe, AB. “When resistance is relatively minor, they tend to pay less attention to managing it than they could.

ROTATE HERBICIDE GROUP NUMBERS, NOT NAMES, TO HELP MANAGE RESISTANCE
Last year in Canada 63% of cereal acres went unprotected by a fungicide application and Canadian
growers paid for it in lost revenue. Protecting your cereal crop with a fungicide can limit disease pressures and yield losses, ensuring your investment retains its value. Bayer CropScience currently offers two of the most trusted cereal fungicides – Prosaro® and Folicur® EW. Prosaro is a protective and curative fungicide that effectively reduces DON levels and has unsurpassed protection against fusarium head blight. This results in higher yield and better grain quality. Folicur EW has a wide window of application, making it one of the most versatile fungicides, while providing excellent protection from a broad spectrum of diseases, including fusarium head blight. Regardless of the conditions that add to the intensity of disease, a timely fungicide application more than pays for itself.
In addition to our excellent fungicide products, we have developed a number of easy-to-use online tools to assist you in understanding how and when
fungicides should be applied. At BayerCropScience.ca/ItPaystoSpray you’ll find local Demonstration Strip Trial (DST) results organized by cereal crop, year and region.
Which fungicide makes the most sense in my area? Should I spray earlier, or later in the season? If my crop looks healthy, is it worth applying a fungicide? The Spray Decision Guide can help you to determine whether or not to spray a fungicide. Find the answer to these questions and more at BayerCropScience.ca/FungicideDecisionGuide. Determining application timing and pointing to the
importance of risk assessment, the Spray Decision Guide is a resource that will help you stay ahead of disease.
The Fungicide ROI Calculator is another tool we’ve provided that will estimate the potential return on investment (ROI) of a fungicide application. Protecting crops against the risk of disease is not only a point of pride for growers, but a sound financial decision. Determining the potential ROI before your application can make your decision on which fungicide to apply that much easier.

34 FARM FORUM / SUMMER 2013
Bayer CropScience has been a proud sponsor of Aggie Days for 10 years. From April 10th to 14th in Calgary, we had the opportunity to help
bridge the urban-rural divide by getting city kids excited about farming. The children were introduced to ideas about farming through hands-on education activities and farming facts posted around the booth. Our hope is that the children who stopped by our booth will have a better understanding and appreciation for the challenges growers are facing today and into the future.

Aggie Days
We had a great response to the “Thank a Farmer” station. The station featured a few facts about growers' contributions and where their food supply comes from. The activity helped educate the children on the true source of their favourite foods and other products, and the importance of agriculture in their day-to-day lives.
Hundreds of children wrote heartfelt thank you cards to farmers. We had a great time at Aggie Days and were excited to provide the kids with an opportunity to thank you for everything you do – look for a postcard arriving in select mailboxes.
