Last few days, I have gotten several questions about potential Reflex carryover to field corn in Georgia. Here are a few of my thoughts:
1) The labeled rotation restriction for field corn following Reflex is 10 months.
2) Average field half-life for Reflex is 100 days. It is probably much shorter in our soils.
3) I have only seen Reflex carryover injury to field corn on the farm 1 time in Georgia. This occurred in Early Co. in a field that received 3 applications of Reflex in cotton the prior year.
4) Most of the weird symptoms that are occurring in Georgia corn fields at this time are not likely caused by Reflex (i.e. assuming excessive rates or delayed applications were not made).
5) My colleagues in Tennessee and Arkansas have been reporting some problems with Reflex carryover to field corn but you must remember that these states have heavier soils with higher organic matter contents than Georgia.
5) The following are some pictures of known Reflex injury to field corn.
