Soybean Sentinel Plot Update

Posted: June 18, 2014

Additional locations are coming on-line as the crop gets underway throughout the state with reports showing an eager start to the crop once planted.

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.

Reports from the past week continue to be very simple with few pests really active thus far—just minor reports of bean leaf beetle and slugs, no diseases thus far. In the coming weeks, more reports will come in as all the fields get planted and emerge.

In the reports below, pests found during scouting are listed with their severity, which is rated on a 1-10 scale with 10 being the highest. Growers should be sure to check their own fields to determine your local populations, but these reports will give you a sense of what pests are active in fields. Our reports are distributed via this weekly newsletter, Penn State’s Field Crop News, and will be available in the next day or two on Penn State’s Field Crop Entomology website.
