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.

February Update - Check tiller populations before adding nitrogen to wheat
Jill Scheidt, MU Extension agronomy specialist, reported on Wednesday, February 8 at 8:40 am the current 2” soil temperature was 38 degrees Fahrenheit. To check the current 2” and 4” bare soil temperature in Lamar please visit the MU Extension webpage found at http://agebb.missouri.edu/weather/realtime/lamar.asp
Check tiller populations before adding nitrogen to wheat. Fields with fewer than 80 tillers per square foot in the fall to late winter may benefit from split applications of nitrogen. If tiller population is 80 tillers or more per square foot, wait until just before wheat joints to add nitrogen for the most efficient usage of the fertilizer. Adding too much nitrogen, can cause lush growth which increase the risk of late freeze damage and encourages aphids.
Now is also a good time to assess weed population, remember if you have henbit that has flowered, with the purple flower, it is too late to spray. Henbit drops its seeds when the flower comes out and is no longer competitive. Winter annual weeds compete with wheat for light, water and nutrients the most during the vegetative stage. The best time to treat weeds is when they are less than 4” in height or diameter.
If you are grazing cattle and growing the wheat for grain, remember to remove cattle before jointing occurs.
The joint is the growing point, so you will want to minimize damage from cattle or equipment as much as possible.
The early bird special to sign up for the crop scouting report is going on the month of February. The crop scouting report subscription will cost $30 per line until February 28. So sign up early and save!
