Weekly Crop Scouting Report
Consider the economics first before spraying fields for Aphids or weeds

When aphids and weeds start showing up in area wheat and corn fields, farmers need to consider the cost of herbicides before application according to Jill Scheidt, agronomy specialist with University of Missouri Extension.
“I scouted fields on April 9 around Golden City and see any aphids yet but temperatures were still cool,” said Scheidt. “If temperatures are below 60 degrees, aphids are not active. If aphids are not present in wheat fields and if temperatures are below 60 degrees, an insecticide is not economical to apply.”
Kevin Bradley, a state weed specialist with University of Missouri Extension, recommends a two-pass herbicide program when spraying corn.
“Over the past 11 years, in 67 percent of corn trials, the highest yield was obtained by using a pre-emergent, followed by a post-emergent herbicide application; regardless of whether you plant conventional or not,” said Bradley.
The economic threshold level of weeds depends on species and growth stage of the weed.
To estimate weed density in wheat, count the number of plants in a square foot in 5 to 10 random places in the field. If weeds make up more than 30 percent of the plant population in that square foot, treatment is justified.
“If weeds make up 5 to 29 percent of the plant population, wheat prices and herbicide costs should be considered first,” said Scheidt.

Each week, extension agronomy specialists and agronomy assistants scout 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 cost of the program is only $35 per phone number, $95 for three numbers, and $30 per phone number for those with 4 or more. For more information about the program, call the Barton County Extension Center at 417-682-3579.
