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
September 30 - Scout for Podworms and observe Hessian Fly free date
Jill Scheidt, agronomy specialist with University of Missouri Extension, scouted fields near Arcola in Dade County and fields near I-49 along Hwy. 126 in Barton County on Sept. 30.
Scheidt observed soybeans in the seed development to full seed stage, with leaves of more mature fields are turning yellow.
“As soybeans enter the full seed development stage, podworms become less of a concern because they prefer to feed on small, tender seeds,” said Scheidt. Late planted and second crop soybeans are most at risk for podworm feeding. “Due to wet weather, a fungus may have killed podworms. Look for podworm mummies to see if the fungus has controlled the podworm population,” said Scheidt.
Scheidt also observed a little grasshopper pod feeding in soybeans with developing seeds, but not enough to cause concern. Threshold level for any pod feeding is when five percent or more of pods are damaged and the insect is present in the field.
The Hessian Fly Free Date is Oct. 10 for counties going east between Newton and Vernon counties to avoid Hessian Fly laying eggs in wheat stems and leaves.
“Control volunteer wheat to minimize insect threats, such as aphids, to nearby wheat fields. If volunteer wheat is nearby, consider applying an insecticide seed treatment or scout for aphids in the fall and early spring, as aphids overwinter in volunteer wheat,” said Scheidt. Aphids need to be scouted for in early spring regardless of a seed treatment.
Scheidt recommends planting a cover crop such as cereal rye to prevent soil erosion and weeds and promote soil health if wheat will not follow your crop. “When planting cereal rye, consider the possibility of a slightly reduced corn yield due to allelopathic properties. Allelopathy refers to a chemical in roots that certain plants excrete so nearby seeds do not germinate,” 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.
