Applying a fungicide at the R3 growth stage shows a return on investment of $17.68 per acre, according to seven-year data from Beck’s Hybrids.
Northern corn leaf blight has increased in prevalence over the past decade-plus across the Midwest. Northern corn leaf blight can cause as much as 30% yield loss if it develops before or during the tasseling and silking phases of corn development.
Spray or not to spray is the annual dilemma farmers face when considering a fungicide application. The most important factor determining the value of a foliar fungicide application is disease pressure.
In addition to planting corn and soybeans seeds, Brady Holst applies a mix of bacteria and fungi with his planter. “We’ve been putting biologicals on with the planter for about five years,” said Holst, who farms with his dad and brother.
The presence of foliar disease around the tasseling stage in corn development can lead to significant yield loss. Yield potential is impacted when the top eight to nine leaves above the ear become riddled with disease.
The first confirmations of tar spot in the United States were in Illinois and Indiana in 2015 and the corn disease has since spread across the Corn Belt. “It’s here and we’re going to have to learn how to deal with it,” said Ryan Gentle, Wyffels Hybrid agronomy manager.
Farmers are always looking to learn something new, especially if it will help them improve their return on investment or increase yield.
Fungal diseases in corn, like tar spot, are advancing. “It’s out there. I would say Illinois had tar spot from north to south this year,” said Phil Krieg, Syngenta Agronomy service representative based in Southern Illinois.
Tar spot, a relative newcomer to the Corn Belt’s disease lineup, is changing the way that growers and agronomists look at fungicides on corn.
To be a star, you have to have a great supporting cast. For soybean plants, fungicides play that role.
A data-driven digital tool which calculates the estimated value of crop protection investment will be available for farmers in 2022.
There’s a dividing line in Illinois that has nothing to do with baseball or football. It deals with disease.
Higher commodity prices change the questions around soybean yields. “Ask yourself, ‘what am I giving up if I don’t do everything to maximize my yields this year?’” said Chad Threewits, Syngenta agronomy service representative for Indiana.
After a mixed bag of weather and moisture conditions, corn and soybean fields in Northern and central Illinois are off and running.
The pressure was on Trivapro®, the Syngenta fungicide with three active ingredients, to prove itself straight out of the gate.
