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.

May 18 - Corn fields look good, wheat approaching dough stage

PDF      Audio

This week Terry Halleran, agronomy specialist with University of Missouri Extension, scouted corn and wheat west of Lamar. 

Wet and rainy conditions made it a little hard to scout.

The corn looked good and was in the V3 leaf stage. However, more heat units and warmer nights are needed to improve on its overall performance. 

“Wheat fields are still showing signs of viral diseases but the time to treat is past so we will have to wait and see how the yields turn out,” said Halleran.

Observations of insects in the field today were negotiable as to be expected due to the weather.

As wheat rapidly approaches the dough stage and prepares to dry farmers should be looking for possible true army worms infestations.  If three to four worms per square foot are found it would be time to consider spraying.  Mustang would do a good job on the armyworm.

“When was the last time you went through your spraying equipment?  For your chemicals to do what you want them to do they must be applied correctly.  Check your flow rate, hoses and nozzles for possible problems.  Check your pressure gauge rating, travel speed, and spray patterns to make sure you are getting adequate coverage.  Make sure you have read and are following the directions on the label when it comes to application and clean up.  And above all protect yourself and your family from possible chemical contamination.  After all it is not always just about you when it comes to chemical safety,” advised Halleran.

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.
