    For those fields of wheat flowering and fields of barley head-out today (May 22), the risk for head scab is moderate in the northern-most counties and in the eastern portion of central Ohio (according to the scab forecasting system at http://www.wheatscab.psu.edu). Persistent rainfall and high relative humidity over the last several days are the primary reasons for the moderate-risk prediction in these regions.

    Ohio State University Extension has conducted manure research on growing crops for several years in an effort to make better use of the available nutrients. Incorporating manure into growing corn can boost crop yields, reduce nutrient losses, and give livestock producers or commercial manure applicators another window of time to apply manure to farm fields.

    Late planting in many areas, the small size of both soybean and corn plants, and damp, cool conditions in some areas all lead to a greater damage potential from slugs.  Although all fields should be scouted for slugs, focus on no-till fields or those fields with cover crops, a history of slug problems, poor weed control, or a lot of residue left on the field.  We don’t have good economic thresholds for slugs in corn or soybean, yet the following guidelines are to helpful in scouting for their presence and intensity.  Egg and adult sampling should occur until late May/early June when newly h

    It’s definitely a big year for cressleaf groundsel (Senecio glabellus), the yellow-flowered weed that can be seen about everywhere right now.  While it is most often found in no-till corn and soybean fields that have not yet been treated with burndown herbicides, there seems to be an above-average number of wheat and hayfields and pastures with substantial populations.

    The kudzu bug is currently being monitored for in nine counties in Ohio including Adams, Athens, Butler, Clermont, Madison, Meigs, Montgomery, Ross and Washington. Traps were set in May and will be checked weekly through June. Overall, zero kudzu bugs have been found on traps in the monitoring counties. Figure 1 illustrates the average number of kudzu bug / total number of traps located in each county participating in the kudzu bug monitoring (highlighted in red).
