Deadline for Atrazine Comments Has Arrived - Producers Encouraged To Let Their Voice Be Heard

The National Corn Grower Association is asking farmers to express their support for the herbicide atrazine at www.ncga.com/atz before the Oct. 5, 2016 deadline.

"Atrazine is a safe and effective crop management tool, and EPA should base their decisions on sound science," said National Corn Growers Production and Stewardship Action Team Chairman Brent Hostetler, a farmer from Plain City, Ohio. "That's why I'm urging farmers to contact the EPA and make their voices heard."

Farming without atrazine could cost farmers up to $59 per acre, according to a 2012 analysis by the University of Chicago. That could mean the difference between corn farmers making a profit or loss on their crop. Atrazine, a key ingredient in nearly 100 herbicide mixes farmers use, is one of the best tools on the market today for combatting resistant weeds that waste water and nutrients.

As part of the draft ecological risk assessment, EPA recommends reducing the aquatic life level of concern (LOC) from 10 parts per billion (ppb) on a 60-day average, to 3.4 ppb. Scientific evidence points to a safe aquatic life LOC at 25 ppb or greater. If this recommendation holds, it would result in a de facto ban on atrazine.

Seeing the Whole Season: How Continuous Crop Modeling Is Changing Breeding

Video: Seeing the Whole Season: How Continuous Crop Modeling Is Changing Breeding

Plant breeding has long been shaped by snapshots. A walk through a plot. A single set of notes. A yield check at the end of the season. But crops do not grow in moments. They change every day.

In this conversation, Gary Nijak of AerialPLOT explains how continuous crop modeling is changing the way breeders see, measure, and select plants by capturing growth, stress, and recovery across the entire season, not just at isolated points in time.

Nijak breaks down why point-in-time observations can miss critical performance signals, how repeated, season-long data collection removes the human bottleneck in breeding, and what becomes possible when every plot is treated as a living data set. He also explores how continuous modeling allows breeding programs to move beyond vague descriptors and toward measurable, repeatable insights that connect directly to on-farm outcomes.

This conversation explores:

• What continuous crop modeling is and how it works

• Why traditional field observations fall short over a full growing season

• How scale and repeated measurement change breeding decisions

• What “digital twins” of plots mean for selection and performance

• Why data, not hardware, is driving the next shift in breeding innovation As data-driven breeding moves from research into real-world programs, this discussion offers a clear look at how seeing the whole season is reshaping value for breeders, seed companies, and farmers, and why this may be only the beginning.
