Several areas of Iowa last week experienced strong winds along with thunderstorms. Fortunately, these storms provided some much-needed moisture for kernel set on corn, but the winds in some places were strong enough to root lodge corn. Corn affected ranged from just silked (R1), the blister stage (R2), to some in the milk stage (R3). In areas with corn not yet tasseled, greensnap occurred. I'll discuss greensnap another time. For this article, I'll discuss the following: Why did some plants root lodge and others didn't? How will root lodging affect yield? And what can we learn that will reduce root lodging in the future?
