News You Can Use

As an agronomic leader, Pioneer takes pride in providing timely and useful agronomic information to the public. Pioneer Field Agronomists have taken this to the next level through their use of Pioneer®GrowingPoint® Agronomy videos. This week, agronomists cover topics about using kernel set to determine stress events, managing Japanese beetles and high nighttime temperatures.

How Kernel Set Can Provide A Stress Roadmap

Pollen shed is controlled by a combination of genetic and environmental factors. The size, placement and amount of kernel set on the corn ear documents when an ear was subject to environmental stress and the severity of the stress. Understanding how corn ears respond to stress can help determine what stress was present, when the stress occurred and what management practices need to be changed for future growing years…Learn more

How Japanese Beetles Prevent Pollination

Emerging in late June, Japanese beetles move into corn crops when they begin to silk. Beetles can prevent pollination if they clip silks during this time. If the silk is shorter than 1/2 inch, a management strategy should be implemented to control the beetles…Learn More

Warm Nights, Low Yields?

Do warm nighttime temperatures have any effect on corn ear development? According to Pioneer Field Agronomist Zach Fore, those warm summer nights that most of us enjoy, aren’t as friendly to corn plant development, but not for the reasons you might think. Fore says warm nighttime temperatures can cause the corn plant to develop too rapidly, which may shorten the reproductive phase and lead to yield reduction…Learn More
