News You Can Use

The holidays are approaching, and our gift to farmers this and every year is the timely, reliable agronomic information they depend on. This week we dive into research on the effect of corn plant population on fungicide, hybrid selection in high residue fields and manganese fertility in soybeans. 

NOTE — No email will be sent next week. We will resume Dec. 30.

Plant Population and Corn Fungicide Response

Pioneer researchers have studied how corn plant population levels affect foliar fungicide response. The theory has been that denser corn canopies created by higher plant populations could be more prone to foliar disease due to reduced light and air movement, resulting in stalk lodging and yield loss…Read more


Hybrid Selection for High Residue Fields

Good residue management and the right hybrid are critical to success in reduced-tillage systems. Pioneer assigns each hybrid a stress emergence score based on field data and tests that mimic extreme cold stress. These results, along with disease resistance, factor into a hybrid’s overall high residue suitability score. Ratings help growers select the optimal hybrid for early planting and reduced-tillage systems…Read more


Manganese Fertility in Soybeans

When it comes to micronutrient deficiencies in soybeans, manganese is one of the most common culprits. Manganese is more likely to be deficient in soils that are sandy, dry or high in pH or organic matter. The symptoms of deficiency are seldom uniform and are strongly tied to soil properties. Luckily, soybeans respond well to manganese fertility treatments…Read more

Liberty® Herbicide, Preferred Herbicide Partner with the Enlist™ Weed Control System

To give farmers the best control of tough and resistant weeds, Corteva Agriscience and BASF are recommending the use of Liberty® and Enlist One® herbicides on Enlist E3™ soybean and Enlist™ cotton acres. These two leading herbicides offer exceptional control of broadleaf weeds including waterhemp, pigweed, kochia, marestail and ragweed species.

“The combination of Enlist One plus Liberty herbicide is lights out on tough pigweed and waterhemp,” said Shawna Hubbard, Trait Herbicide Product Manager, Corteva Agriscience. “Using both products postemergence will help farmers get the cleanest fields they’ve seen in years in areas infested with tough weeds. That’s why Liberty herbicide is now Corteva’s recommended glufosinate for use with the Enlist weed control system."…Read more
