    Over the course of the next year, you will hear much about the pest, soybean cyst nematode.  No stranger to Ohio, since the 1980’s, farmers in Ohio have been monitoring this pest.  The first surveys, early 1990’s, SCN occurred sporadically in the state but some populations were very high.  In a survey of fields in southern Ohio, high populations of SCN were found in fields where yields were consistently low.  One of the more recent check-off funded projects, identified that more fields than 20 years ago has SCN.  Among the 143 fields sampled at a depth of 6 to 8 inches in 51 counties in Ohi

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.
