Q: What is Ignite® herbicide?
A: Ignite is a nonselective contact herbicide
that controls more than 120 grass and
broadleaf weeds, including woolly cupgrass,
ragweeds and waterhemp. When
growers use Ignite on corn hybrids or soybean
varieties with the LibertyLink® trait,
they get similar benefits as those offered by
glyphosate-tolerant systems, while providing
a unique mode of action for weed control.
With built-in tolerance to Ignite, the
LibertyLink trait provides excellent crop
safety. Ignite paired with the LibertyLink
trait is the only nonselective alternative to
glyphosate tolerant systems.
Q: On which crops can growers apply Ignite?
A: Ignite can be applied in-season, over-thetop
of LibertyLink corn, cotton, canola
and new LibertyLink soybeans. Growers
also can use Ignite in pre-plant burndown
programs just prior to planting or before
crop emergence.
Q: What is the difference between Ignite and
Liberty® herbicide?
A: Ignite is a new, more powerful, cost-effective
formulation for use on all LibertyLink
crops. What does Ignite control? Ignite
controls more than 120 grass and broadleaf
weed species, including tough-to-kill
weeds such as woolly cupgrass, cocklebur,
lambsquarters, foxtails, morningglories,
marestail, waterhemp and velvetleaf. Ignite
also controls weeds that have known resistance
to multiple herbicide classes, such as
ALS- and glyphosate-resistant weeds.
Q: Are there any resistance concerns with Ignite?
A: Ignite has a unique mode of action with no
documented weed resistance globally. How
quickly does Ignite work? Ignite kills weeds
in days vs. weeks. Visual effects and control
show within two days to four days after application
under favorable growing conditions.
Q: When should growers apply Ignite?
A: Application timing varies by crop, but the
first application should be made after crop
emergence during early weed growth,
when weeds are 3 inches to 4 inches tall,
to avoid yield loss from weed competition.
In soybeans, that means growers should
make the first application of Ignite no later
than 22 days after crop emergence to ensure
optimal weed control. Applications of
Ignite in the North Delta region should bemade at 10 days after crop emergence. A
subsequent application can be made based
on weed size.
Q: What are the labeled rates for Ignite?
A: Corn and soybean growers can apply 22
fl oz/A per application up to a season
maximum of 44 fl oz/A. However, in soybeans,
if environmental conditions prevent
timely application, a single application
may be made of up to 36 fl oz/A of Ignite
herbicide. Please see the Ignite label for use
directions and additional restrictions.
Q: What are some general application guidelines
for Ignite?
A: Start with properly calibrated and cleaned
equipment. Fill the spray tank half-full with
water and start agitation. Add tankmix
partners (if needed) and complete filling
the spray tank with water. Then add the
appropriate amount of Ignite and continue
agitation. If foaming occurs, use a silicone based
anti-foam agent. For thorough spray
coverage, 15 gallons to 20 gallons of water
per acre (GPA) are required (20 GPA to 40
GPA with dense canopy).
Q: What are the preferred nozzle types when
applying Ignite?
A: Apply Ignite using nozzles and pressure that
generate medium-size spray droplets. The
preferred nozzle type is a flat fan that will
generate a pressure of 40 PSI to 60 PSI and
a droplet size between 250 microns and
350 microns. Nozzles capable of delivering
medium spray coverage when properly
selected and operated include:*
- Spraying Systems: TeeJet® Visifl o Flat,
XR or XRC TeeJet Extended RangeFlat, or Turbo TwinJet® Flat spray tips
- Greenleaf Technologies: TurboDrop® XL or AirMix® spray tips
- Hypro: Guardian™, Variable Pressure ™, Total Range™ or Albuz® AXI
spray tips
Q: Can Ignite be tankmixed with other herbicides
or insecticides?
A: Ignite can be tankmixed with most other
crop protection products. A comprehensive
tankmix partner list can be found on
the Ignite label.
Q: Should growers include any additives in
the tankmix?
A: In corn, add ammonium sulfate (AMS) at
3 lbs/A (17 lbs/100 gal). When temperatures
exceed 85 degrees, the AMS rate
may be reduced to 1.5 lbs/A (8.5 lbs/100
gal) to reduce potential leaf burn.
Q: Should growers use residual herbicides in
addition to Ignite?
A: Complementary residual herbicides in
addition to timely applications of Ignite
are strongly recommended. Please see the
label for residual herbicides that can be
tankmixed with Ignite. For complete herbicide
program recommendations contact
your retailer or local Bayer CropScience
representative.
Q: Are there special considerations when using
Ignite in corn or soybeans?
A: Ensure fields are properly identified so the
applicator knows which fi elds are LibertyLink
and which fields are glyphosate-tolerant.
When the two systems are utilized
in rotation, it provides growers with a great
resistance management tool.
