Insecticides for Control of Leafminers of Sugarbeets

Updated March 12, 2003 by Gary Hein and John Thomas

Economic Threshold:
Leafminers attack sugarbeets early in the season when leaf area is limited; however, the leaf area of the mines is seldom great enough to warrant treatment (25% defoliation).
