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

March 22 - Very little freeze damage seen in wheat

PDF      Audio

Jill Scheidt, agronomy specialist with University of Missouri Extension, scouted fields west of Lockwood for the March 22 crop scouting update.

Wheat was found to be in the jointing stage.  “The joint on most plants was 2-3 inches above the soil level, so if you have not applied nitrogen yet, it should be done soon to avoid damaging any head development,” said Scheidt.

“Last week’s freeze appears to have only burned leaf tips, no damage to the head was seen. I think the head was close enough to the ground that it was not affected by the cold weather,” said Scheidt.

When the stem was cut open to examine the head, the head was white and healthy.

Scheidt observed one to three bird cherry oat aphids per foot of row. The threshold level for bird cherry oat aphids are 12-15 per foot of row. “Aphid population may be down due to recent cold snaps. Aphids become less cold tolerant as temperatures warm, therefore, cold snaps can reduce the population. This does not mean that aphids will no longer be a threat. Aphids should be scouted for all season long, as they will suck sap out of the grain. Aphids asexually reproduce live young in as little as 3 days after being born, so populations can increase very quickly,” said Scheidt.

According to the Lamar Weather Station at 9:20 am on March 22, the 2-inch bare soil temperature was 49 degrees Fahrenheit.

The Barton County Extension office will be a drop off for fence and livestock feed supplies from 9-3 until April 6th for those affected by the wildfires.

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.
