Precautions and Remarks
0.11 to 0.187 Kale, collards, mustard, turnip, mizuna, mustard spinach, and rape.
See label to determine if other Brassica (Cole) leafy vegetables are
registered. Apply to crop when weeds are small and actively growing.
Will control most legumes. For kale, collards, mustard, and turnip (roots)
PHI = 30 days. For turnip tops PHI = 15 days. Mustard green injury has
been observed in some research trials.

Apply postemergence for control of grasses. See label for adjuvant and
rate. Adding crop oil may increase the likelihood of crop injury at high
air temperatures and high humidity. Very effective in controlling annual
bluegrass. Apply to actively growing grasses not under drought stress.
For greens crops, PHI = 14 days. For turnip roots, PHI = days.
0.2 to 0.3 ALSO LABELED FOR RAPE GREENS. Apply to emerged grasses. Consult
manufacturer's label for specific rates and best times to treat. See
label for adjuvant and rate. Adding crop oil to Poast may increase the
likelihood of crop injury at high air temperatures and high humidity. For
greens crops, PHI = 30 days. For root crops, PHI = 14 days.

Up to 0.031 Apply post-directed using hooded sprayers for control of emerged
weeds. If crop is contacted, burning of contacted area will occur. Use a
nonionic surfactant or crop oil with Aim. See label for rate. Coverage is
essential for good weed control. Can be tank mixed with other registered
herbicides.
Not labeled for turnip greens. Apply as a hooded spray in row middles,
as shielded spray in row middles, as wiper applications in row middles,
or postharvest. To avoid severe injury to crop, do not allow herbicide to
contact foliage, green shoots or stems, exposed roots, or fruit of crop.
PHI = 14 days.
