A relatively dry week here in Michiana (by this year’s standards only!) means irrigation systems continue to run … feeling much more “normal” as far as July in the Midwest goes. Corn fields on sandy knolls are starting to roll their leaves during the hottest part of the day.
Corn has shifted its energy to reproduction from vegetation as pollination has begun. Tassels emerged and the silks are following.
With the mostly adequate soil moisture and cool-to-normal temperatures, pollination should go off without a hitch. Anthers (the part that dangles from the tassel) will shed pollen on the corn silks (quite the love story isn’t it!). Remember each silk represents a kernel of corn.
Corn that suffered from wind damage continues to straighten up, but see how it was working to survive, sending tillers out to help!
Continue to scout corn for disease pressure. Inspect lower leaves first looking for lesions of yellowing or dead leaf tissue. Consider treating with fungicide if the disease reaches the ear leaf.
Beans are also transitioning stages as pods are beginning to develop on lower branches.
Scout fields for a second flush of weeds and spray accordingly. If volunteer Roundup Ready corn is a problem, call the office for a recommendation. Don’t worry if treated volunteer corn doesn’t look like it’s dying. This corn was sprayed over a week ago with Assure, and doesn’t really look much different from the “outside”.
Further inspection however tells us much more. On grass plants, like corn, the growing point is in the whorl. To check the health, pull the whorl and check its condition. See this corn is definitely dying! Yay!
Thanks for scouting with us!
