Recommended Controls
All Weeds
Weed control methods in legumes vary by production system
and crop.
For legumes that are no-till, direct-seeded into a killed crop
(such as after a rye cover crop, or wheat) growers often use a
burndown herbicide with a preemergence herbicide. For
legumes direct-seeded into tilled soil, growers often combine
one or more preemergence herbicides at planting with one or
more cultivations. Sometimes, growers also apply a
preemergence herbicide after the last cultivation to improve
control of late-emerging weeds. Small, emerged weeds in
both systems can be controlled with selective postemergence
herbicides and/or shielded applications of nonselective
herbicides
For specific weeds controlled by each herbicide, check the
Relative Effectiveness of Herbicides for Vegetable Crops
table.
Rates provided in the recommendations below are given for
overall coverage. For a banded treatment, reduce amounts
according to the portion of acre treated.
Non-Pesticide
Beans (Dry), Beans (Fresh), Lima Beans, Peas (Dry), Peas
(Fresh), Southern Peas/Cowpeas | A stale seedbed can be
prepared prior to transplanting with flame weeding or very
shallow cultivation to control emerged weeds, instead of
herbicides. Legumes lend themselves to this stale seedbed
practice because they are often planted after common weeds
have emerged in tilled soil. Uniform and close plant spacing
in the row promotes rapid canopy cover, and fresh market
growers can keep larger between row spacing clean with
between row cultivation tools for hand-pickers or mechanical
harvesters. A rolling cultivator on a wide tool-bars offer
effective high-speed cultivation.
Pesticide
Aim EC (2) (carfentrazone) POST
Beans (Dry),
Beans (Fresh), Lima Beans, Peas (Dry), Peas (Fresh),
Southern Peas/Cowpeas | 0.5-2 fl. oz. per acre. Apply prior to
or within 24 hours after seeding, or apply between crop rows
with hooded sprayer. Do not allow spray to contact crop. Use
