    IPM Recommendations

    • Effective control must target both aboveground and underground plant structures.
    • Hand-pull plants in planting beds prior to seed maturation.
    • Apply a mulch layer 3 inches deep on planting beds to reduce seed germination.
    • Apply an appropriate pre-emergent herbicide prior to seed germination or apply an appropriate post-emergent herbicide directly to target weeds.
