    IPM Recommendations

    • Hand-pull plants in planting beds prior to seed maturation.
    • Shallow tillage or hoeing will control young plants in planting beds.
    • 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.
