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 2016 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.

June 15 - Corn looks healthy, Soybeans at first trifoliate stage

PDF      Audio

Jill Scheidt, agronomy specialist with University of Missouri Extension, scouted corn and first crop soybeans west of Lamar and near HH Hwy on June 15.

Scheidt observed corn in the 12-14 leaf and beginning tasseling stages.

“Corn looks healthy at this point. It has common rust on the leaves, which normally doesn’t require a fungicide treatment in Missouri unless a large percentage of the leaf area is covered,” said Scheidt.

Scheidt advises those who have not applied nitrogen, it is not too late.

“Yield increases can still be seen if nitrogen is applied up to two weeks after tasseling. It is better to apply before, but last minute applications can still make a yield difference,” said Scheidt.

Scheidt observed first crop soybeans in the emerging to first trifoliate stage.

To determine soybean population in 30” rows, multiply the number of plants in 17.5 feet by 1,000. For 15” rows multiply number of plants in 34’ 10” by 1,000. For 7.5” rows multiply number of plants in 69’ 8” by 1,000.

To calculate seeding rate first multiple percent germination, percent pure live seed and percent live seed emergence and divide the desired plant population by the product of those factors.

“Be sure to control weeds when less than 2-4” in height or diameter for the most effective control, weeds are the biggest competitor in reducing yields in any crop,” 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.
