AbstractEPTC IO percent granules, Trifluralin 10 percent granules and Poast were evaluated for southern sandbur (cenchrus echinatus) control. Trifluralin resulted in variable control ranging from 90 percent down to 55 percent. EPTC produced good but sometimes varied control when applied in February, prior to the germination of the weeds, and repeated in April, June and July. Poast was effective postemergence only when applied to small seedlings. It was ineffective when applied to established sandbur.
