A user of the revised Economic Threshold that we recently published in the Integrated Crop Management News noticed that there was an incorrect function. I didn’t see it because it didn’t make a difference with the numbers that I used worked through it. We have replaced the previous threshold spreadsheet with a corrected one.
I apologize for the inconvenience and ask that you make sure that you are using the correct Excel spreadsheet. The correct spreadsheet is an additional resource to this article and is now available from the original article published that was published July 9, 2008.
