Not labeled for transplanted crop. To improve preemergence control
of late emerging weeds. Apply only when crop has 4 to 5 true leaves, is
well established, and growing conditions are favorable. Will not control
emerged weeds. Incorporation not recommended.
Apply as a directed spray to soil between rows after crop emergence when
crop plants have reached three to four true leaf stage of growth. Avoid contacting
foliage as slight crop injury may occur. Set incorporation equipment
to move treated soil around base of crop plants. Will not control emerged
weeds. PHI = 30 days.
May be applied sequentially in bare ground and plasticulture production
systems at a minimum of 21 days apart. Refer to label for specific instructions.
0.024
to 0.036 Apply postemergence only after the crop has reached 3 to 5 true leaves
but before first female flowers appear. Do not apply sooner than 14 days
after transplanting. Use nonionic surfactant at 1 qt per 100-gal of spray
solution with all postemergence applications. Avoid over-the-top application
when temperature and humidity are high. PHI = 57 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 crop oil
concentrate or a nonionic surfactant with Aim. See label for directions.
Coverage is essential for good weed control. Can be tank mixed with other
registered herbicides.
See labels
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, stems,
exposed, roots, or fruit of crop. PHI = 14 days.

1 to 1.5 pt
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. PHI = 3 days.

*Mode of action (MOA) code developed by the Weed Science Society of America.
Apply postemergence for control of emerged grass in cantaloupes (muskmelons).
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. PHI
= 14 days.
0.5 to 0.75 oz
Up to 2.1 pt
4 to 6.4 oz
Precautions and Remarks
0.024 to 0.036 Apply after seeding or prior to transplanting crop. For transplanted crop,
do not transplant until 7 days after application. Rate can be increased to 1
ounce of product per acre to middles between rows. PHI = 57 days.
Up to 1
Row middles only. May be applied sequentially in bareground and plasticulture
production systems at a minimum of 21 days apart. Refer to label
for specific instructions.
0.19 to 0.3 Row middles only. Use a shielded sprayer directed to the row middles to
reduce drift to the crop. In plasticulture, prevent the spray from contacting
the plastic. Consult label for further instructions. PHI = 48 days.
