    As we continue to search for profitable ways to expand the manure application window in Ohio, we have begun to research dragline application of manure to growing soybeans. While this would potentially open up more time for manure application in the spring, our initial research goal is to look at the ability to apply manure to emerged double crop soybeans after wheat. For many years, livestock producers have successfully applied liquid manure to newly planted soybeans in July to help provide moisture for germination and emergence.

  3. Historical Soybean Cyst Nematode Map
    Author(s): Anne Dorrance

    As we wait another week for the fields to dry out, this provides some time to sample soil for the SCN populations.  The SCN Coalition theme for the next few years is What’s your number?  Do you know where SCN is in your fields and what the current population is sitting at?  If its high, then there is a second number – what is the SCN type?  Which addresses the bigger question can it reproduce on the SCN resistance source PI 88788 or Peking.  All of these numbers can impact management of this root pathogen and future losses.

    Results from Marion County have been added to the 2018 Ohio Soybean Performance Trials pdf: https://stepupsoy.osu.edu/soybean-production/variety-selection/ohio-soybean-performance-trial

    In Marion County, the early soybean trial (2.5-3.3 RM) yielded 37.3-68.1 bu/acre (average of 57.2 bu/acre). The late soybean trial (3.4-4.1 RM) yielded 41.4-66.7 bu/acre (average of 56.1 bu/acre).

    Let’s face it – we’ve had historic rains in parts of Ohio during 2018 and we are now observing many late season issues that come with this.  Seed quality is one of them and the symptoms or warning signs that there could be issues are on the stems.  The stems in some fields are heavily colonized with a mix of disease pathogens that cause Anthracnose, Cercospora, and pod and stem blight (Figure 1).  The bottom line is that all of these diseases can be better managed with higher levels of resistance but ultimately during 2018 – we had a perfect storm, lower levels of resistance combined with h

  8. 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?
