| Q. |
What is Aim herbicide?
|
| A. |
Aim herbicide is a postemergence herbicide that contains unique
chemistry developed by FMC Corporation. The active ingredient in Aim
herbicide is carfentrazone-ethyl, a compound discovered by FMC
scientists. The active ingredient is a member of the aryltriazolinone
family of herbicides. |
| |
| Q. |
What weeds does Aim control?
|
| A. |
Aim
herbicide provides excellent control of six troublesome broadleaf
weeds that corn growers have been fighting for years - velvetleaf,
redroot pigweed, black nightshade, pitted morningglory, ivyleaf
morningglory and common lambsquarters. Aim also aids in the control of
several other key weeds such as waterhemp, smartweed, kochia, common
cocklebur, and many triazine and ALS-resistant weeds. |
| |
| Q. |
How does Aim control susceptible weeds?
|
| A. |
The
carfentrazone-ethyl in Aim herbicide is an inhibitor of
protoporphyrinogen oxidase (PPO). This means that carfentrazone-ethyl
disrupts the enzyme system that controls chlorophyll synthesis. This
results in disruption to cell membranes which leads to rapid
desiccation of susceptible weed species. |
| |
| Q. |
How quickly does Aim work?
|
| A. |
Aim
herbicide has shown exceptionally fast weed control, with symptoms
of control visible within hours of application. Weeds turn brown and
begin dying within two to three days. Rain has minimal impact on weed
control. |
| |
| Q. |
When is Aim applied?
|
| A. |
Aim
herbicide can be applied in fields any time from emergence until the
corn is in the eight-leaf collar stage. Corn in the eight collar stage
will normally be no taller than 24 inches. For broadleaf weed control,
Aim should be applied when weeds are no more than four inches tall,
except in the case of morningglories, which should be treated at 2-3
true leaves or less, velvetleaf, which can be up to 18 inches tall, and
lambsquarters, which should be treated up to 3 inches tall. |
| |
| Q. |
Can Aim be used with herbicide tolerant corn hybrids?
|
| A. |
Aim
can be used with Roundup®, Liberty® or imidazolinone (IMI)
herbicides. When tank mixing with Roundup or imidazolinone herbicides,
use only corn hybrids that have been engineered for tolerance as
recommended on their respective labels, and use the adjuvant system
recommended by the partner herbicide. |
| |
| Q. |
What crops can be rotated following an Aim application?
|
| A. |
Aim
herbicide does not have residual activity; therefore, it can be
applied to a corn crop without worry about rotational crops that will
be planted the following growing season. Non labeled crops can be
rotated 30 days following application. |
| |
| Q. |
Can Aim be tank mixed with other herbicides?
|
| A. |
Aim will be labeled for tank mix with most of the current postemergence
corn herbicides on the market so that growers can make one
postemergence application for full-spectrum weed control in their corn.
Some approved tank-mix partner herbicides include: atrazine, 2,4-D
amine, Accent®, Banvel®, Beacon®, Clarity®, Exceed®, Hornet®,
Lightning®, Marksman®, NorthstarTM, Permit®, Roundup®, Scorpion® III,
Spirit®. |
| |
| Q. |
Does corn treated with Aim show any adverse symptoms?
|
| A. |
Corn
treated with Aim will normally display a small amount of leaf
speckling that will greatly decrease within one to two weeks. Symptoms
will be seen only on those leaves present at application. This
speckling does not adversely affect corn growth or yield. All corn
hybrids evaluated to date have reacted similarly to the treatments of
Aim herbicide with no hybrid selectivity. |
| |
| Q. |
Is there a definite need for Aim herbicide?
|
| A. |
Yes!
Aim provides early control of six broadleaf weeds that are major
problems for corn growers each year. If left untreated, these weeds
result in lost yield, harvest problems and more extreme weed growth in
the coming years. With Aim, growers have an economical choice to
control six troublesome weeds, plus suppression of several other tough
broadleaf weeds. |
| |
| Q. |
Why has Aim been labeled a reduced risk herbicide?
|
A.
|
Most
herbicides bring with them a certain level of environmental risk. When
compared to alternative methods, Aim posed less environmental threat
due to its low use rate and low soil residual. Even so, growers should
refer to the label for appropriate precautions. |
| |
| Q. |
Is Aim expensive?
|
| A. |
Actually,
Aim is quite economical. Its low use rate, competitive pricing and
superior control make Aim an exceptional value. |
| |
| Q. |
Can Aim be used for pre-plant burndown? |
| A. |
Yes!
Aim can be tank mixed with Touchdown®, Roundup® or other glyphosate
brands for use in burndown of emerged grasses and braodleaf weeds prior
to corn or soybean planting. At a low rate of 1/4 ounce per acre in a
tank mix, Aim aids in speed of activity on weeds for faster
burndown. Weed control is obvious within two days after application of
the tank mix. At a rate of 1/2 ounce per acre in a tank mix, better
contol of difficult-to-control broadleaf weeds is achieved in addition
to faster burndown. Aim assists the most in controlling
lambsquarters, redroot pigweed, ivyleaf morningglory and pitted
morningglory. At both rates, Aim can be used without risk of
antagonism with Touchdown, Roundup, or or glyphosate products . |
