We don’t know what the insect pressure will be like later on yet this year. What we can do, however, is remind agronomists and crop consultants what we think are the most important insects for you to watch for in each of three key crops: corn, soybeans and wheat.
Colonies of bird cherry-oat aphid were spotted in winter wheat at Draper in South Dakota last week. As winter wheat is heading toward booting stage, careful monitoring of populations by frequent scouting is highly recommended.
Wheat head armyworms are becoming more common, and thus more conspicuous, throughout north central and south central Kansas. This insect is only a very minor pest most years, but there are always a few (>1%) infesting most wheat fields.

The wheat markets followed corn lower. Monday’s Crop Progress report held few surprises. Otherwise, wheat news was rather sparse Tuesday, which seemingly opened the door to outside influences, particularly from the corn market. That is, diving corn costs undercut wheat usage as feed. September CBOT wheat slumped 5.5 cents to $5.245/bushel as Tuesday’s trading ended, while September KC wheat sank 6.75 cents to $6.2125/bushel, and September MWE wheat sagged 4.50 cents to $6.1875.
