POSTEMERGENCE: Apply when crop has 3-5 leaves and before flowering. Include 0.25% NIS. Controls nutsedge.

ROW MIDDLES: Apply to area between rows of plastic.

UNDER PLASTIC: Apply just before laying plastic. Wait 7 days to plant. Use low rate.

OVER PLASTIC: Use spot treatment for nutsedge control.
