A raceme of burs, spikelets 2-flowered, 1-3 spikelets per bur. |

FOUND: |
Field sandbur is found mostly on sandy soil. It is troublesome mainly because the spiny burs cause discomfort to livestock. |

Field sandbur has continual emergence throughout the summer and causes problems with control especially with non-residual herbicides like POAST PLUS and SELECT. Some control has resulted with dormant incorporated applications of TREFLAN in February-March. |
