    Pasture Mealybugs

    The pasture mealybug is a small, white, oval-shaped insect that feeds on multiple grasses, including forages, row crops like sugarcane and corn, and turf. Adults are fuzzy and fluffy-looking, around ~ 1/16 to ~3/16 inch (thickness of one to three pennies stacked). Nymphs are much smaller, about 1/64 inch, of creamy-white color, and are the most active feeders.

    Pasture mealybugs eat plant sap found in blades of grass, sugarcane and other grass crops. They can also dig into the soil to feed on roots, and they often survive cold winters underground. Their appetite can damage crops and lead to widespread die-offs of entire pastures or fields.

    Live Updates

    June 24, 2026:
    Sefina (BASF) has a Section 2(ee) for use in pastures and Sivanto Prime (Bayer) has a crisis exemption for sugarcane. Additionally, a Section 18 (quarantine) exemption could be granted to allow for continued use of this chemical moving forward. Savant will be used at an application rate of 14 fl oz/acre year.

    Note: We do not have data on effectiveness yet. These guidelines are only suggested reinforcements and procedural recommendations for pasture mealybug management.
