Insecticides for Control of Aphids of Sugarbeets

Updated March 12, 2003 by Gary Hein and John Thomas

Economic Threshold:
Green peach aphid and bean aphid can occasionally be found in Nebraska. The major impact of these insects is the potential for virus transmission, but these aphid-transmitted viruses do not occur often and are impossible to predict. Treatments to control virus transmission are not likely to be effective. Treatments for direct aphid damage should only be considered if leaf symptoms (curling, stunting) are present on plants less than 8-12 weeks old and active colonies are present.

This list is not inclusive. See http://www.greenbook.net or other resources for additional registrations.
