Frequently Asked Questions

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 .
