Warrant® Herbicide Use in Corn, Soybeans, and Cotton
What You’ll Learn...
 Warrant® Herbicide is a residual herbicide with
application flexibility in corn, soybeans, and cotton.
 The product can be applied preplant, at-planting,
preemergence, and postemergence in these crops.
 With an optimum use rate of 1.5 quarts/acre, up to
two applications can be made in the crop to help
provide season-long residual weed control.
 The product can be tank mixed with other
herbicides for control of emerged weeds and
residual control of weeds not listed on the Warrant
Herbicide label.
Warrant® Herbicide
Warrant Herbicide provides residual control of
grasses and small-seeded broadleaf weeds, including
foxtails, lambsquarters, Palmer pigweed, and
waterhemp (Table 1). The product will not control
emerged weeds, so it must be applied to a weed-free
soil surface or in a tank-mixture with products that
provide postemergence control of weeds at the time
of application. Warrant Herbicide can be tank mixed
with Roundup® brand agricultural herbicides and
applied to corn, soybean, and cotton crops that
include glyphosate-tolerant technology. The
encapsulated technology helps provide improved crop
safety and up to 30 days residual weed control.
for extended residual weed control. Drop nozzles can
help to provide optimum spray coverage and weed
control when corn reaches 24 to 30 inches in height.
When used in Roundup Ready® Corn 2 and corn with
Roundup Ready® 2 technology, the product can be
tank mixed with a Roundup agricultural herbicide
targeting emerged weeds that are 2 to 4 inches in
height.
Warrant® Herbicide can be tank mixed with other
products registered for field corn including atrazine,
Aim®, Balance® PRO, Balance® Flexx, Callisto®,
Clarity®, Distinct®, Impact®, Linex®, Lorox®,
Marksman®, Princep®, Resource®, and 2,4-D. Read and
follow the most restrictive label directions for each
product in a tank mixture.
Soybeans
Warrant Herbicide can be applied preplant, atplanting, PRE, and POST in soybeans using rates from
1.25 to 2 quarts/acre depending on the soil texture
and organic matter content. The optimum use rate is
1.5 quarts/acre. The product can be applied up to the
R2 growth stage of soybeans. It is recommended that
applications be made before soybeans reach the V3
stage in order to help maximize soil contact, reduce

Warrant Herbicide can be applied preplant, atplanting, and preemergence (PRE) in corn only in
certain southern states (AL, AR, GA, LA, MS, NM, NC,
OK, SC, TN, TX, and VA). The product can be applied
postemergence (POST) in corn without any state
restrictions. Application rates of 1.5 to 3 quarts/acre
can be used, depending on the soil texture and
organic matter content. Warrant Herbicide can be
used in field corn and production seed corn, and is not
recommended for use in sweet corn.

crop interference, and receive the greatest benefit
from the residual weed control. Directed applications
after the V5 growth stage of soybeans help to
increase soil coverage and canopy penetration.
Warrant® Herbicide can be tank mixed with other
products registered for soybeans including Authority®
brands, Assure®, Basagran®, Classic®, Cobra®,
FirstRate®, Flexstar®, Fusilade®, metribuzin, Poast®,
Pursuit®, Raptor®, Reflex®, Roundup® agricultural
herbicides, and Select®. Read and follow the most
restrictive label directions for each product in a tank
mixture.
Cotton
Warrant Herbicide can be applied preplant, atplanting, PRE, and POST in cotton using rates from
1.25 to 2 quarts/acre depending on the soil texture
and organic matter content. Once cotton has
emerged, the options for broadcast applied residual
herbicides becomes limited; however, Warrant
Herbicide can be applied up until the crop reaches
first bloom. The optimum timing is when cotton is in
the 2- to 3-leaf stage using a rate of 1.5 quarts/acre.
Directed applications may be used to increase soil
coverage and canopy penetration after cotton
reaches the 5- to 6-leaf stage.
Warrant Herbicide can be applied in a tank mixture
with a Roundup agricultural herbicide up to first
bloom in Genuity® Roundup Ready® Flex Cotton. The
product can be tank mixed with other products
registered for cotton including Assure®, Caparol®,
Cotoran®, Direx®, Flexstar®, Fusilade®, Poast®, Prowl®,
Pyrimax®, Reflex®, Select®, Staple®, and Valor®.
Warrant Herbicide can also be tank-mixed with
products applied POST-directed or with a hooded
sprayer, including MSMA and Layby™ Pro. Read and
follow the most restrictive label directions for each
product in a tank mixture.
General Use Information
 Up to two applications of Warrant Herbicide can be
applied in a crop during the season, not to exceed
a total of 4 quarts/acre per season.
 Mechanical incorporation or preplant incorporation
application is not recommended.
 After application, it is important for Warrant
Herbicide to be activated by water for the product
to be effective. At least 0.5 inch of rainfall or
irrigation is needed for good activation of the
herbicide. If this does not occur within two weeks
after application, a shallow cultivation, if possible,
can help with activation.
 Application of Warrant Herbicide followed by
conditions that do not favor adequate crop growth
or which causes stress (cold, wet soils), or under
waterlogged conditions from excessive irrigation
or rainfall, may result in crop injury. Application
with other residual herbicides may increase the
potential for crop injury.
Warrant Herbicide qualifies for Roundup Ready PLUS®
Crop Management Solutions incentives. The Roundup
Ready PLUS platform provides useful information
about weed management, including how to reduce the
risk, how to manage it and how to receive incentives
to offset herbicide costs. The platform features
regionally-specific recommendations for using
herbicides, as well as agronomic recommendations
developed by leading university weed scientists. More
