Insecticides for Control of Flea Beetles of Sugarbeets

Updated March 12, 2003 by Gary Hein and John Thomas

Economic Threshold:
Flea beetle populations can be increased in certain rotations (following alfalfa and dry beans) or if host weed populations are high. Avoid planting sugarbeets after alfalfa or in areas where flea beetle populations were high the previous year. Closely monitor beet fields planted near alfalfa fields or weedy areas for adults moving out of these areas.

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