‘New’ Doesn’t Always
Mean ‘Better’
Many have tried to imitate Halex® GT herbicide since its successful introduction in
2008. Armezon® PRO herbicide is touted as being a new, flexible post-emergence
herbicide, but it doesn’t come close to matching the proven, post-emergence
performance of Halex GT on difficult weeds.
1.Halex GT delivers a broader spectrum of control on
broadleaf weeds and grasses. That’s why it’s no
surprise that 9 out of 10 growers who try Halex GT
use it again.1
Halex GT controls more than 90 of the toughest broadleaf
weeds and grasses including ragweeds, waterhemp,
lambsquarters, pigweeds and foxtails. It controls broadleaf
weed biotypes resistant to ALS, triazine and glyphosate
herbicides.

2. Halex GT delivers longer lasting residual control.
3. Halex GT is more convenient.
The superior residual control of Halex GT allows it to be
sprayed early in the season, well in advance of row closure
to protect yield. Trials show Armezon PRO has a shorter
length of residual control, so growers often wait for all of
their weeds to emerge before application. While this may
prevent a second or third flush of weeds from emerging,
it is recommended to apply a post-emergence herbicide
with long-lasting residual.
While Armezon PRO claims to provide powerful
residual activity and long-lasting residual control,
a picture is worth a thousand words.
4. Halex GT is a better option for herbicide
resistance management.
Armezon PRO contains two active ingredients and
two modes of action. Halex GT contains three active
ingredients and three modes of action for better weed
resistance management.
Halex GT is Glyphosate with Residual™ and provides a
more convenient alternative to other post-emergence,
glyphosate corn herbicide programs.

Halex GT does not require a tank mixture with glyphosate
for effective weed control. For Armezon PRO to be an
effective post-emergence weed control program, it
is recommended to add glyphosate. Trials show that
without the addition of glyphosate, you will not see full
control of many grasses such as annual bluegrass,
downy brome, woolly cupgrass, green foxtail, yellow
foxtail and fall panicum.
“I use Halex GT over other brands
because of the reliability and the
consistency that it has given me. It is
a no-brainer. You can put Halex GT
out there and it goes and performs
every season. It just works.”

Active ingredient comparison on waterhemp
An active ingredients component trial highlights the importance of using a herbicide with multiple effective modes of action. In
the trial below, waterhemp was seeded in 4-inch pots, and then each pot was treated with either Halex GT, Armezon PRO or
an isolated active ingredient from each product.
More of the modes of action in Halex GT provided control of waterhemp,
while only one mode of action in Armezon PRO provided effective control.

• The experimental design of this trial was conducted in 4-inch pots filled with soil and seeded with waterhemp.
• The trial was held at a greenhouse temperature of 79-82 degrees F.
• Treatments were sprayed at 150 L/ha water carrier volume.
• Halex GT contains 3 active ingredients (glyphosate, mesotrione and s-Metolachlor). Because glyphosate provides no residual weed control, it was not included in this residual trial.
