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 2015 weekly scouting reports, print the 2015 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

July 22 - Late planted soybeans must beat freeze

PDF      Audio

Jill Scheidt, agronomy specialist with University of Missouri Extension, scouted fields near Arcola in Dade County and near Verdella in Barton County on July 22.

Corn Report
Scheidt observed corn that was finished pollinating and either in the blister or milk stage.

To find out how well your corn pollinated, you can view Scheidt’s video, “How to tell how well corn pollinated.” 

“Once pollination has occurred, silks are no longer needed, and Japanese beetles are not a threat,” said Scheidt.

Soybean Report
Scheidt observed soybeans ranging from emerging to bloom stages.

“Japanese beetle populations are lowering and should not be of much concern,” said Scheidt.

Threshold levels for Japanese beetle in soybean are 30 percent defoliation before bloom and 20 percent defoliation during and after bloom.

Bill Wiebold, plant science professor at University of Missouri conducted a two-year study on this issue. Using a seeding population of 150,000 seeds per acre and a maturity group three, soybeans planted in mid-July yielded around 30 bushels per acre.

Over 30 years of data from University of Missouri weather stations suggests that the median probability date for a killing freeze, of 28 degrees, begins Nov. 7.

“Soybean yield is protected from frost if the plants have reached physiological maturity. If a killing frost occurs before this time, harvest will be difficult and soybeans are likely not to change color,” said Scheidt.

The weekly field scouting report is sponsored by University of Missouri and Barton County Extension. For more information on the scouting report, or to learn how to receive the information earlier by telephone, contact the Barton County Extension Center at (417) 682-3579.
