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
July 20 - Japanese Beetles in fields are decreasing
Jill Scheidt, agronomy specialist with University of Missouri Extension, scouted corn and soybeans east of Carthage, near Highway 96 on July 20.
She observed corn in the hard dough and dent stages. Black layer, or maturity, occurs about 20 days after the dent stage. Data from Mississippi and Louisiana show the field drying rate from maturity, or black layer, occurs at about 0.6 percent per day until the grain reaches 15 percent moisture.
“No earworm or Japanese beetle feeding on kernels was seen,” said Scheidt.
Scheidt observed soybeans in the 4-5 trifoliate and beginning bloom stages.
"Less than 5 percent defoliation was seen on leaves for Japanese beetle, grasshopper and bean leaf beetle,” said Schedt.
The threshold level for any foliage feeding insect in soybean is 30 percent defoliation before bloom and 20 percent defoliation during or after bloom. Scheidt recommends scouting soybeans for podworms if they are in the bloom stage.
Threshold level for podworm in soybeans are one podworm per foot or when 5 percent or more pods are damaged.
“A little bacterial blight was seen on soybean leaves, most likely due to the recent warm, wet weather. New leaves are healthy and green so the disease has stopped spreading and fungicide treatment is not necessary. The hot, dry weather likely slowed the disease,” 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.
