ammonium sulfate as an additive. For overhead irrigated

can be applied after the first fully expanded trifoliate in any
county. For fresh peas in Michigan (MI 24c exp. 12/31/23)
and Minnesota (MN 24c exp. 12/31/25) only: apply 1 pt. per
acre in a tank-mix with other herbicides after seeding peas
and before emergence. Use only once in 2 years on same soil.
18-month waiting period before planting most other crops.
REI: 24-hour. PHI: 30-day for succulent beans; 45-day for

Beans
(Dry), Beans (Fresh), Lima Beans, Peas (Dry), Peas (Fresh),
Southern Peas/Cowpeas | 3.2 pts. per acre. ï»¿ ï»¿ï»¿ï»¿
Apply when weeds are small and after peas have 3 pairs of
leaves or first trifoliate leaf of beans is fully expanded. An
additional application of Basagran is allowed not to exceed 2
pts. per acre, and an additional application of Poast is allowed
at 2.9 pts. per acre. REI: 48-hour. PHI: 30-day. HRAC 06,

Sandea (75) (halosulfuron) POST PRE
Beans
(Dry), Beans (Fresh), Lima Beans, Southern Peas/Cowpeas |
0.5-1 oz. per acre. For Southern peas/cowpeas: apply 0.5 oz.
per acre after planting but prior to soil cracking. Or use up to
1.0 oz. per acre as a directed postemergence application to the
row middles when plants have 2-4 trifoliate leaves but before
flowering. For Lima beans and fresh beans: apply 0.5-1.0
oz. per acre after planting but prior to soil cracking. Or, use
0.5-0.67 oz. per acre for postemergence applications over
crop and weeds when plants have 2-4 trifoliate leaves but
before flowering, or use up to 1 oz. per acre as a directed
postemergence application to row middles with no crop
contact. For dry beans: apply up to 0.67 oz. per acre after
planting but prior to soil cracking. Or, use or as a
postemergence application over crop and weeds when plants
have 1-3 trifoliate leaves but before flowering, or use up to 1
oz. per acre as a directed postemergence application to row
middles with no crop contact. Use 0.5-1 pt. of NIS per 25
gals. of spray solution if emerged weeds are present at time of
preemergence application. Use lower rates on coarse soils
with low organic matter. Not recommended when
temperatures are cool due to potential for crop injury. Do not
exceed 1 oz. per acre per crop cycle or 2 oz. per acre per 12month
period. REI: 12-hour. PHI: 30-day. HRAC 02.
Sharpen (2.85SC) (saflufenacil) POST PRE
Peas
(Dry), Peas (Fresh) | For fresh peas in Illinois, Iowa,
Michigan, and Minnesota: apply 0.75 fl. oz. per acre preplant
incorporated or preemergence up to 3 days after planting
before cracking. For lentils in Minnesota: use up to 2.0 fl. oz.
per acre as described for fresh peas. For dry pea and
chickpeas: apply 1-2 fl. oz. per acre to the surface as a
burndown early preplant through preemergence up to 3 days
before cracking. Add MSO at 1 pt. per acre when used as a
pre-plant burndown. Suppresses black nightshade,
lambsquarters, pigweed, and velvetleaf. Higher rates in lentils
and chickpeas will provide more, but still limited, residual
weed control. Plant legumes at least 1/2-inch deep to avoid
injury. Do not apply group 14 herbicides within 30 days of
planting. REI: 12-hour. HRAC 14.
Sonalan HFP (35.4) (ethalfluralin) PRE

Peas (Dry) | 2.258.0
fl. oz. per acre. Spring-apply early-preplant, preplantincorporated,
or preemergence up to 3 days after planting
before cracking. Rate depends on soil texture, organic matter,
and pH. Do not use on sand soils with less than 1% organic
matter or apply after crop emerges. Michigan, Minnesota,
and Wisconsin only: a fall application before soil freezes is

crop emerges. Provide simultaneous burndown of emerged
weeds and residual premergence weed control. Michigan,
Minnesota, and Wisconsin only: a fall application is allowed
for control of weeds ahead of winter. REI: 12-hour. PHI: 90day.

dry peas and chickpeas: apply preplant-burndown, earlypreplant,
