Crop scouting reports

Crop scouting is an essential part of integrated pest management (IPM). Scouting programs are designed to protect and maximize crop yield and quality while minimizing the risk associated with pesticide use. 

Each week, an extension agronomy specialist scouts fields in Barton County and then report their findings through an automated phone service and email message. The message will go out to everyone signed up for the program.

The weekly field scouting report is sponsored by University of Missouri Extension and Barton County Extension.  To receive the 2016 weekly scouting reports, print the Crop Scouting Enrollment Form, complete and return with payment to Barton County Extension, 801 E 12th, Lamar, MO 64759 or contact the MU Extension Center in Barton County, 417-682-3579.

The cost of the program is only $35 per phone number, $95 for three numbers and $30 per phone number for those with four or more.

Current weekly report

September 20 - Hessian Fly-Free date

PDF      Audio

Jill Scheidt, agronomy specialist with University of Missouri Extension, reports for the Sept. 20 crop scouting update.

Wheat Report
“The Hessian Fly-Free Date is October 10th for Jasper county north to Vernon county, then stretching east across the state. Hessian Fly avoidance is not the only reason to wait to plant wheat. Planting too early can cause plants to grow too lush, making them susceptible to freeze damage and a desirable place for aphids to overwinter,” said Scheidt.

Soybean Report
“I have not seen new or increased sudden death in soybean fields, but have noticed dead or fallen leaves in areas that had sudden death,” said Scheidt. Identify Sudden Death Syndrome (SDS) by a yellowing of leaves, but veins remain green; this usually occurs on top leaves first. “SDS has been common this year due to wet weather during planting and cool temperatures during bloom, which encourage disease development,” said Scheidt.

Milo Report
“Corn earworm have been reported in milo fields that have not yet turned color. It is probably getting too late in the season for insects to reach threshold levels, but fields should be monitored until the first frost or until plants reach an undesirable maturity for insect feeding as the weather this year has been unusual,” said Scheidt.

MU Extension
University of Missouri Extension programs focus on the high-priority needs of Missourians to improve lives, communities and economies by providing relevant, responsive and reliable educational solutions. Each county extension center, with oversight by locally elected and appointed citizens, is your local link to practical education on almost anything.
