  1. R3 Stage Soybean
    Author(s): Laura Lindsey

    A few weeks ago, Dr. Anne Dorrance wrote an article about foliar fungicide application to soybean for control of frogeye leaf spot disease. She recommended spraying at the R3 growth stage. (Her entire article is here: https://agcrops.osu.edu/newsletter/corn-newsletter/2018-19/we-have-found-some-whiskers-spores-cercospora-sojina).

     

    What is the R3 growth stage? And has it already passed?

  7. Soybean aphids
    Author(s): Andy Michel , Author(s): Kelley Tilmon

    We have heard reports of growers spotting a few soybean aphids in their fields. Finding aphids at this time of year is consistent in the past—we have seen them arrive later and later. We do have a lot of late-planted soybean that are in R4 or R5 stage soybean. Remember that our economic threshold to treat soybean aphids is a rising population of 250 aphids per plant. But also remember that, at higher growth stages (>R6) the threshold increases dramatically. At this point it is important to note that none of the fields in Ohio have reached treatable levels.

    We have had the opportunity to walk additional Ohio fields where soybeans were damaged by off-target movement of dicamba since our last C.O.R.N. newsletter article on this subject (see link below), and we continue to hear about even more affected fields.  This situation continues to develop across the Midwest and South, and everyone involved is trying to assess causes and what these mean for future use.  A couple of action items here for anyone associated with an off-target dicamba movement and injury situation:

    Persistent wet weather prevented soybean planting in many areas of the state. Late planting reduces the cultural practice options for row spacing, seeding rate, and relative maturity.

  10. field day
    Author(s): Amanda Douridas

    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).
