| Economic Threshold: In fields with a high risk of wireworm damage, wireworms can be controlled with seed treatments or with the use of soil insecticides. Sugarbeets are very sensitive to organophosphate insecticides applied at planting. These products should not be applied in the furrow even for control of wireworms. |
