    Air temperatures dropped to an average of about 25-32 degrees on at least two nights over the last few days. Understandably, some wheat producers are concerned that these temperatures may have caused some damage to their crop. We will have to see what happens over the next few days.

    One of the requirements for the registration of XtendiMAx, Engenia, and FeXapan is the investigation of any non-performance (ineffective control) by the respective companies, which then has to be reported to the USEPA.  The goal of this reporting is apparently to try to track the development of resistance as soon as it occurs in a few fields, which would then allow time to modify practices so that the rate of resistance in other fields is slowed.  We encourage growers and consultants to take the time to scout for non-performance, within 14 days after application according to information fro

    As a result of the warm winter and early spring, weed growth in no-till fields is ahead of schedule.  Fields not treated with burndown herbicides last fall or during the earlier drier period this spring can have some large weeds at this point.  Many fields need time to dry out following the most recent rains before they will tolerate traffic, which will allow weeds to get even larger and more challenging to kill.  Large marestail can be especially problematic due to the combination of glyphosate and ALS resistance in most populations.  Cool weather can reduce the activity of the herbicides

    There was little progress made on corn planting last week due to persistent rains and saturated field conditions (https://www.nass.usda.gov/Statistics_by_State/Ohio/Publications/Crop_Progress_&_Condition/index.php).  As of Sunday May 7, 46 percent of Ohio’s corn crop was planted - only 4% more than the previous week. Moreover, according to NASS estimates, only 12% of the crop has emerged.

    Join specialists in the field this summer to see hands on what insect and disease pressure is present. The specialists will help participants identify insects and diseases and then discuss management strategies. The series begins with a Pasture Walk on May 23 at 5:30 pm. The field borders the Ohio Caverns so an optional group tour of the Caverns has been set up at 4pm ($15).
