Soybean Update

–by Dr. Jeff Whitworth and Dr. Holly Schwarting

We are still not finding any pests at threatening levels in soybeans, yet.  Dectes stem borer adults are actively ovipositing in petioles and larvae are/will be hatching and tunneling into stems for the next 4-6 weeks.  For more information please see the KSRE publication Dectes Stem Borer: https://www.bookstore.ksre.ksu.edu/pubs/MF2581.pdf.

There has been some concern about white flies in soybeans.  They do seem to be plentiful but they will not cause any problems relative to yield.
