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.

Current weekly report
January Update - Evaluate tiller stands in wheat
Tiller stands in wheat should be evaluated January to early February. In fields with 80 or more tillers per square foot, nitrogen applications should be made just before jointing. If nitrogen is added earlier, lush growth can occur, making wheat susceptible to late freeze damage and increased aphid populations.
Fields with less than 80 tillers per square foot, may benefit from a split application of nitrogen. Livestock should be removed before jointing, if keeping wheat for grain.
If planting grain sorghum, consider varieties resistant to sugarcane aphid and adding a seed treatment. Sivanto and Transform are currently labeled for sugarcane aphid control in Missouri.
When planting soybean, consider purchasing a soybean cyst nematode resistant variety and adding a seed treatment. A recent survey has shown 75% of Missouri fields have SCN. If you are unsure, submit a soil sample to the MU nematology lab for an egg count and SCN race test to obtain management strategies.
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.
