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.

April 19 - Wet conditions consider a fungicide to protect flag leaves and prevent Head Scab

PDF      Audio

Jill Scheidt, agronomy specialist with University of Missouri Extension, scouted fields near EE Hwy, east of I-49 and on the northeast side of Lamar for the April 19 crop scouting update.

Wheat was found to be in the heading and beginning flowering stages.

Scheidt observed powdery mildew moving up the plant, and present on some flag leaves. Powdery mildew begins as light-green to yellow flecks on the leaf surface that develop into patches of cottony white mold growth that turn a grayish in color. Temperature ranges of 59-72 degrees F and prolonged periods of cloudy weather favor powdery mildew development. High nitrogen levels, lush growth and dense canopies also favor powdery mildew.

Scheidt recommends a fungicide treatment for head scab in wheat due to the warm weather and forecasted rains. Head scab develops in the flowering stages in humid, overcast weather conditions with temperature ranges from 77-86 degrees F and when wheat is subject to prolonged wetness. “Head scab can result in blank kernels and possible mycotoxin development, which is toxic to humans and livestock at varying levels. The best time to apply a head scab fungicide for the most effective results is when 50% of flowering is complete,” said Scheidt. 

Corn was found to be in the emerging to the third leaf stages.

“The lower leaves looked tattered from the recent rains. No black cutworm or other insect damage was seen. Black cutworms should be scouted for as they are more common in wet weather. Look for plants that are cut off at or just below the soil level when scouting for black cutworm damage,” 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.
