YieldGard Plus delivers effective and consistent in-plant protection
against western, northern and Mexican corn rootworms and European
and southwestern corn borers, for a zone of protection that goes from
the root to the tassel—from the time you plant.
- YieldGard Plus contains broad spectrum, in-the-bag control of secondary
pests like wireworm, white grub, sugarcane borer, southern corn
stalk borer, seedcorn maggot and early flea beetle.
- Effective and consistent control helps maximize root systems and
healthier stalks.
- YieldGard Plus maximizes the amount of moisture and nutrients that
are absorbed and carried through the plant for greater yield potential
and protection, less lodging and less ear drop.
- YieldGard Plus provides convenience to the grower since it reduces
the amount of insecticide needed to be handled and time scouting for
insect damage.
- YieldGard Plus returns up to $20 per acre more profit. (Two-year
average yield advantage, Monsanto data.)
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 within
or adjacent to the stacked B.t. technology corn can serve as a refuge for
corn rootworm. Any corn hybrid that does not contain a B.t. technology
for control of European and southwestern corn borer and is planted
within 1⁄2 mile (1⁄4 mile preferred) of the stacked B.t. technology corn
field can serve as a refuge for corn borer.
- Plant a refuge on every farm where stacked B.t. technology corn
hybrids are planted.
- Plant the refuge at the same time as stacked B.t. technology corn.
- Mixing non-B.t. seed with stacked B.t. technology seed for use in the
refuge is not permitted.
- If the refuge is planted on rotated ground, then stacked B.t. technology
corn must also be planted on rotated ground.
- If the refuge is planted in continuous corn, then the stacked B.t.
technology corn field can be planted on either continuous or rotated
ground.
- Adjacent and separate refuge fi elds must be owned or managed by the
same grower planting stacked B.t. technology.
Common Refuge
The fi rst option is to plant a common refuge that will serve as the refuge
for both corn borer and corn rootworm. The common refuge must be
planted with corn hybrids that do not contain B.t. technologies for the
control of corn borer or corn rootworm.
Common Refuge Requirements
On each farm, up to 80 percent of corn acres can be planted with
stacked B.t. technology corn. The refuge area must represent at least 20
percent of the grower’s corn acres (stacked B.t. technology acres plus
any non-B.t. acres) as shown below. The refuge can be within or adjacent
to the stacked B.t. technology field and can be planted as a block,
strips within the field, or as a perimeter around the field. If perimeter or
strips are used for the refuge, the strips must be at least four consecutive
rows wide.
