Crop Profile for Sugar Beets in Colorado. University of Idaho: Cooperative Extension. Integrated Pest Management Guide for Sugarbeet Root Maggot. For more detailed information on chemical control of sugarbeet root maggot, consult the North Dakota State University webpage.īechinski, E., R. Both granular and liquid insecticides are available for managing sugarbeet root maggot and should be applied immediately after fly numbers exceed economic thresholds. Chemical controlĬhemical management of sugarbeet root maggot is challenging and requires several considerations, such as timing, weather, and product formulation. The addition of cover crops prior to beet planting can help reduce feeding injuries caused by sugarbeet root maggot. After harvest, tilling deep into the soil will expose overwintering larvae to natural enemies and freezing temperatures, but may compromise soil health. Planting early will allow sugar beets to grow beyond the seedling stage. Sugar beets planted in fine, sandy soils are more susceptible to feeding injury.Ĭrop rotation is recommended, but alone is ineffective since flies can migrate to and from neighboring fields. Proper irrigation can decrease the severity of feeding injury on plants since frequent irrigation causes larvae to move closer to the surface where plants are less susceptible. Aside from conserving natural enemies, there are no commercially available biological controls for management of sugarbeet root maggot. There are several natural enemies of sugarbeet root maggot including ground beetles, predatory flies, birds, and some species of naturally occurring entomopathogenic fungi such as Metarhizium anisopliae. Chemical control is generally warranted if captures average 40-45 flies per trap from the start of the season. Insecticides should be applied if the running tally exceeds the threshold. Compare the running tally, calculated by adding total trap averages, from the day of peak with thresholds in table 1 of the Integrated Pest Management Guide for Sugarbeet Root Maggot. Control decisions should be made when captures in the daily average column have peaked. A daily average can be obtained by dividing the trap average by the number of days since traps were last checked. Fly captures should be recorded for all traps and used to calculate a trap average. Recordkeeping is necessary to inform decisions related to management. It is recommended that growers monitor and check each individual field since fly activity can differ between adjacent fields. Remove any weeds that might interfere with the trap. Traps should be spaced at intervals of several hundred yards and positioned for easy checking. These traps should be deployed in spring along the fencerow or ditch bank along the sugar beet field, but not within the field. After counting flies of sugarbeet root maggot, discard the old trap and replace it with a new one. Over time, insects will cover the sticky surface and prevent additional captures, therefore traps should be checked a minimum of two times per week. Fly abundance can be monitored with yellow sticky traps.
