| Greenbugs and greenbug mummies |
Greenbugs continue to persist in many wheat and other small grain fields. The threshold for greenbugs in wheat at this time of the growing season considering a grain value of $6.50 and a control cost of $12/acre is an average 3 greenbugs/tiller. Greenbugs suck plant juices and inject toxins into plants. These aphids are pale green, approximately 1⁄16 inch long, with a dark green stripe on their back.
