YieldGard Rootworm delivers effective and consistent in-plant protection against western, northern and Mexican corn rootworms, for a zone of protection around the roots from the time
you plant.
- YieldGard Rootworm offers broad-spectrum, in-the-bag control of
secondary pests like wireworm, white grub, seed corn maggot and
early flea beetle.
- YieldGard Rootworm protects more consistently and effectively than
traditionally applied insecticides, allowing corn to maximize its root
system.
- YieldGard Rootworm’s larger root system enables the corn plant
to utilize more moisture and more nutrients and ultimately produce
higher yields.
- YieldGard Rootworm maximizes and protects yield potential and limits
lodging.
- YieldGard Rootworm provides convenience to growers since the
amount of insecticide handled and the time spent scouting for insect
damage are reduced.
How Refuges Must be Established
On each farm, plant up to 80 percent of the corn acres with YieldGard® Rootworm or YieldGard VT Rootworm/RR2™ corn. Plant
at least 20 percent of the corn acres to a corn refuge that does not
contain a B.t. technology for control of western, northern, and Mexican
corn rootworm. Unlike products containing YieldGard Corn Borer
traits, YieldGard Rootworm and YieldGard VT Rootworm/RR2 have
the same refuge requirements in both corn- and cotton-growing areas. The corn refuge can be treated for control of corn rootworm larvae
and other soil pests with soil-applied, seed-applied, or foliar-applied
insecticides. The corn refuge can be treated with a non-B.t. insecticide
to control late-season pests such as corn borer, however the YieldGard
Rootworm or YieldGard VT Rootworm/RR2 corn must also be treated
if sprayed at a time when rootworm beetles are present. Corn refuge
options include YieldGard Corn Borer, YieldGard Corn Borer with
Roundup Ready® Corn 2, Roundup Ready Corn 2, and conventional
corn, but no B.t. product for corn rootworm management.
Plant the refuge within or adjacent to YieldGard Rootworm
or YieldGard VT Rootworm/RR2 corn field. Separate by a
road, path, ditch, etc., but not by another field. Adjacent refuge
fields must be owned by or managed by the grower.
Corn- and Cotton-Growing Areas Refuge
Planting Requirements
Any corn hybrid that does not contain a B.t. technology for control
of western, northern, and Mexican corn rootworm and is planted
at approximately the same time within or adjacent to the YieldGard
Rootworm or YieldGard VT Rootworm/RR2 field corn can serve as a
refuge. The refuge can be YieldGard Corn Borer, YieldGard Corn Borer
with Roundup Ready Corn 2, Roundup Ready Corn 2, or conventional
corn.
- Plant a refuge on every farm where YieldGard Rootworm or
YieldGard VT Rootworm/RR2 corn hybrids are planted.
- Plant the refuge at the same time as YieldGard Rootworm or
YieldGard VT Rootworm/RR2 corn.
- Mixing non-B.t. seed with YieldGard Rootworm or YieldGard VT
Rootworm/RR2 seed for use in the refuge is not permitted.
- If the refuge is planted on rotated ground, then YieldGard Rootworm
or YieldGard VT Rootworm/RR2 corn must also be planted on
rotated ground.
- If the refuge is planted in continuous corn, then the YieldGard Rootworm
or YieldGard VT Rootworm/RR2 field can be planted on either
continuous or rotated ground.
- Adjacent refuge field must be owned or managed by the
same grower planting YieldGard Rootworm or YieldGard VT
Rootworm/RR2 technology.
