Similar to the past few growing seasons, again this year The Pennsylvania Soybean Promotion Board is funding a Soybean Sentinel Plot Program, which is being managed by Penn State Extension and The Dept. of Entomology at Penn State. In this effort, Penn State Extension Educators are regularly scouting twenty-two ‘typical’ soybean fields in sixteen counties across the state, reporting the populations of plant pathogens and insect pests that they find.

For the past few years, folks in Pennsylvania have heard reports from midwestern states of continuous corn growers struggling to control populations of western corn rootworms that developed resistance to some Bt corn varieties. Thus far, this problem has occurred elsewhere, with the closest fields with suspected resistance being found in central Michigan and New York north of Ithaca. Unfortunately, this problem may now have found a home in Pennsylvania.
