ENVIRONMENTAL HAZARDS 
 
This product is toxic to fish. Do not apply directly to water, or to areas where surface water is present or to 
intertidal areas below the mean high water mark. Do not contaminate water when disposing of equipment 
washwaters or rinsate. Apply this product only as directed on the label. 
 
Non-Target Organism Advisory: 
This product is toxic to plants and may adversely impact the forage and habitat of non-target organisms, including 
pollinators, in areas adjacent to the treated site. Protect the forage and habitat of non-target organisms by 
following label directions intended to minimize spray drift. 
 
Groundwater Advisory: 
Topramezone is known to leach through soil into groundwater under certain conditions as a result of agricultural 
use. Use of this chemical in areas where soils are permea ble, particularly where the water table is shallow, may 
result in groundwater contamination. 
 
Acetochlor is known to leach through soil into groundwater under certain conditions as a result of label use. This 
chemical may leach into groundwater if used in areas where soils are permeable, particularly where the water 
table is shallow. Acetochlor demonstrates the properties and characteristics associated with chemicals detected 
in ground water. The use of this chemical in areas where soils are permeable, particularly where the ground water 
is shallow, may result in ground water contamination. 
 
Surface Water Advisory: 
This product may impact surface water quality due to runoff of rain water. This is especially true for poorly draining 
soils and soils with shallow groundwater. This product is classified as a high potential for reaching both surface 
water and aquatic sediment via runoff for several mont hs or more after application. A level, well-maintained 
vegetative buffer strip between areas to which this product is applied and surface water features such as ponds, 
streams, and springs will reduce the potential loading of topramezone and its transformation products from runoff 
water and sediment. Runoff of this product will be reduced by avoiding applications when rainfall or irrigation is 
expected to occur within 48 hours. 
 
Acetochlor has properties that may result in surface water contamination via dissolved runoff and runoff erosion. 
Use practices to minimize the potential for dissolved runoff and/or runoff erosion. 
 
DIRECTIONS FOR USE

A. PRODUCT INFORMATION 
215-18 is an emulsifiable concentrate (EC) herbicide that provides systemic control or partial control of many 
emerged broadleaf weeds and grasses combined with soil re sidual weed control in field corn (grown for grain, 
silage, or seed) and popcorn. Use this product on conventional and herbicide-resistant corn hybrids. AMVAC has 
not tested all inbred field corn lines for tolerance to this product. Before using this product, refer to seed company 
recommendations for use on inbred lines of field corn. This product contains two modes of action. 
Susceptible weeds will stop growing soon after application while complete control of weeds may take several 
more days, depending on growing conditions, and weed species and size. When applied broadcast to emerged 
weeds as directed, this product will control or partially control the broadleaf weeds listed in TABLE 1 and the grass 
weeds listed in TABLE 2. 
215-18 may be tank-mixed with other corn herbicides to provide both broader spectrum and residual weed 
control. Refer to Tank Mixes in the Crop Use Directions. It is the pesticide user’s responsibility to ensure that all 
products in the listed mixtures are registered for the intended use. Users must follow the most restrictive 
directions for use and precautionary statements of each product in the tank mixture. 
Applications of 215-18 must also include recommended spray additives. Refer to Additives and Mixing Order for 
directions in this label.

3Tank-mixing atrazine at 0.25 to 0.5 lb active per acre/A with 215-18 herbicide will enhance control of emerged 
grass weeds. 
42015-18 herbicide minimum use rate of 30 fl oz/A is required for grass weeds listed as C=Control. When rates 
below 30 fl oz/A are applied, a tank mixture of 215-18 herbicide and glyphosate is recommended. 
52015-18 herbicide use rate of 40 fl oz/A is required for control of this grass weed. 
 
1. Mode of Action 
215-18 contains the active ingredients topramezone (HPPD inhibitor, Group 27) and acetochlor (very long chain 
fatty acid inhibitor, Group 15). Topramezone is absorbed by leaves, roots, and shoots and is translocated to the 
growing points of sensitive weeds, and controls weeds by inhibiting carotenoid biosynthesis. Temperatures and 
moisture conditions which favor active plant growth and development are important for optimum topramezone 
activity. Acetochlor is a root and shoot growth inhibitor that controls susceptible weed germinating seedlings 
before or shortly after they emerge from soil. Acetochlor requires adequate soil moisture for optimum activity 
and provides residual control of sensitive weeds. If an activating rainfall does not occur within 7 days following 
application of 215-18, degree of residual weed control will be affected. 
 
RESISTANCE-MANAGEMENT RECOMMENDATIONS 
For resistance management, please note that 215-18 contains a Group 27 (Topramezone) and a Group 15 
(Acetochlor) herbicide. Any weed population may contain plants resistant to Group 27 and Group 15 herbicides. 
The resistant individuals may quickly dominate the weed population if these herbicides are used repeatedly in 
the same fields. Follow appropriate resistance-management strategies.

xxx648-202004212021092820250721819 Page 9 of 22 
 
 
 
To delay herbicide resistance, take as many as possible of the following steps: 
x Rotate the use of 215-18 or other Group 27 or 15 herbicides within a growing season sequence or among 
growing seasons with different effective herbicide groups that control the same weeds in a field. 
x Use tank mixtures with herbicides from different effective herbicide groups if such use is permitted at rates 
that will control the target weed(s). Consult your local extension service or certified crop advisor if you are 
unsure as to which active ingredient to use. 
x Adopt a diversified weed-management program for herbicide use that includes scouting and uses historical 
information related to herbicide use and crop rotation. Consider tillage (or other mechanical control 
methods), cultural (e.g., higher crop seeding rates, precision fertilizer application methods and timings to 
favor the crop and not the weeds), biological (e.g., weed-competitive crops or varieties or cover crops) and 
other management practices. 
x Scout after herbicide application to monitor weed populations for early signs of resistant individuals. 
Indicators of possible herbicide resistance include: (1) failure to control a weed species normally controlled 
by the herbicide at the dose applied, especially if control is achieved on adjacent weeds; (2) a spreading 
patch of non-controlled plants of a particular weed species; (3) surviving plants mixed with controlled 
individuals of the same species. Prevent weed seed production in the affected area by an effective 
alternative herbicide from a different group or by a mechanical method such as hoeing or tillage. Prevent 
movement of weed seeds to other fields by cleaning harvesting and tillage equipment when moving 
between fields and planting clean crop seed. 
x If a weed population continues to survive after treatment with this product, discontinue use of this product, 
and switch to another management strategy or herbicide with a different effective mode of action (MOA), 
if available. 
x Contact your local extension specialist, certified crop advisors, and/or AMVAC representative for additional 
pesticide resistance-management and/or integrated weed-management recommendations for specific 
crops and weed biotypes. 
 Also, for more information on Weed Resistance Management, visit the Herbicide 
Resistance Action Committee (HRAC) on the web at http://www.hracglobal.com. 
x For further information or to report suspected herbicide resistance, contact AMVAC at 1-888-462-6822.

2. Best Management Practices 
Apply herbicides using proper application techniques, including application timing and appropriate spray volumes 
for thorough coverage of weeds. Use full rates of 215-18 and any additional herbicides in tank mixtures, or when 
using herbicidal and crop rotation strategies. In addition, the following practices should be followed: 
 
x Use cultural (e.g., crop rotation) and mechanical (e.g., tillage) weed management tactics. 
x Use crops with herbicide-resistant (HR) traits and/ or HR trait stacks for more efficient crop and MOA 
rotation. 
x Correctly identify weeds and know where the weeds are in your fields. 
x Start with clean fields. Tillage or a burndown herbicide program can control emerged weeds prior to 
planting. 
x Clean equipment to prevent the spread of weeds seeds. 
x Use residual herbicides in pre-emergence and early post-emergence applications. 
x Scout fields soon after herbicide application to identify escaped weeds, population shifts, and herbicide 
resistant biotypes. 
x Closely monitor problem areas in fields with difficult-to-control weeds or dense weed populations. 
x Control weed escapes by spot herbicide applications, rope wicking, cultivation or hand removal of weeds, 
or other techniques to stop weed seed production and the accumulation of seeds in the soil bank. 
Stopping weed seed development will decrease we ed populations from year to year and help prevent 
major weed shifts. 
 
3. Insecticide Information 
215-18 does not cause interaction with soil-applied insecticides. It may be used sequentially with soil-applied 
insecticides or in combination with foliar-applied insecticides registered for use in corn. Follow the directions for 
use on the insecticide label. 
 
B. ADDITIVES 
Postemergence applications of 215-18 require the addition of an adjuvant and a nitrogen fertilizer source to 
achieve optimum weed control. AMVAC recommends the use of a product which has been reviewed and approved 
by the Council of Producers & Distributors of Agrotechnology (CPDA) Adjuvant Certification Committee. 
 
ADJUVANTS: 
x 215-18 alone – Use methylated seed oil (MSO) at 1-2 qt/100 gallons of water (0.25% to 0.5% v/v) or high 
surfactant methylated oil concentrate (HSMOC) at 1-2 pt/100 gallons of water (0.125% to 0.25% v/v). Use 
a higher rate of adjuvant during periods of hot, dry weather and during periods of moisture stress. The 
use of oil-based adjuvants increases the potential for leaf burn necrosis following application, however, 
corn development and yield are not affected. 
OR 
 
x Tank Mixtures with 215-18 – Use nonionic surfactant (NIS) at 1 qt/100 gal lons of water (0.25% v/v). NIS 
is recommended when tank-mixing 215-18 with glyphosate-containing herbicides. Oil-based adjuvants

xxx648-202004212021092820250721819 Page 11 of 22 
 
(MSO, HSMOC) may be used in tank mixtures with 215-18, however, use of these adjuvants can cause leaf 
burn necrosis within a few days after treatment. Corn development and yield are not affected. 
AND 
 
 
NITROGEN FERTILIZER SOURCE: 
Add spray grade ammonium sulfate (AMS) at 1.5 to 2.5 poundslb/A or urea ammonium nitrate (UAN, 28-34%) at 
1.25 to 2.5 gallons per 100 gallons of water (1.25% to 2.5% v/v). Use higher rates during periods of hot, dry weather 
and during periods of moisture stress. A liquid AMS product which delivers an equivalent amount of ammonium 
sulfate per acre may be used. Commercial liquid solutions of AMS contain approximately 3.4 poundslb of 
AMS/gallon.

215-18 may be applied in tank-mix combinations with labeled rates of other products labeled for the application 
method and timing to corn. The tank-mix partner must be used in accordance with the label restrictions and 
precautions. No label dosage rates may be exceeded. Do not mix 215-18 with any product prohibited for tank 
mixtures. Refer to the specific crop section for rates and other restrictions. 
 
215-18 is formulated to mix readily in water. Prior to adding 215-18 to the spray tank, ensure that the spray tank 
is thoroughly clean, particularly if a herbicide with the potential to injure corn was previously used. 
 
It is the pesticide user’s responsibility to ensure that all products are registered for the intended use. Read and 
follow the restrictions, precautions and directions for use on all included product labels. Users must follow the 
most restrictive directions and precautionary statements of each product in the tank mixture. 
 
215-18 is recommended to be used sequentially or tank mixed with other herbicides as part of a complete weed 
control program. Tank-mix recommendations are for use only in states where the sequential or tank-mix product 
and application site is registered. Refer to Crop Use Directions for more details and for specific tank-mix 
restrictions. Read and follow the applicable Restrictions and Directions for Use on all products included in any 
tank-mix. The most restrictive labeling applies to tank mixes. Do not use liquid fertilizer as a carrier for 
postemergence applications of 215-18. Use only water as a carrier.

2. Tank-Mixing Order Instructions 
Following are mixing order guidelines for 215-18 either alone or with other components, including spray 
adjuvants: 
 
a. Water – Fill spray tank ½ to ¾ full using clean water and begin agitation. 
b. If included, add water-soluble PVA packets to tank and thoroughly mix. Ensure PVA packets are 
completely mixed in spray tank before proceeding. 
c. Add water-soluble additives, including dry and liquid fertilizers such as AMS. 
d. Add water-dispersible products such as wettable powders, dry flowables, suspension concentrates, 
or suspo-emulsions. 
e. Add water-soluble products. 
f. Add 215-18, other emulsifiable concentrates, and oil-based adjuvants such as MSO. 
g. Fill the remainder of the tank with water. 
h. Maintain adequate and continuous agitation during the entire application of the tank contents. 
 
3. Compatibility Testing for Components 
If mixing 215-18 with pesticide products not listed on this label, test the compatibility of the intended tank mixture 
prior to mixing the products in the spray tank. The following procedure assumes a spray volume of 15 gallons per 
acre/A. For other spray volumes, adjust the amount of the water used accordingly. Check compatibility as follows: 
 
a. Place 20 fl oz of water from the source that will be used to prepare the spray solution in a clear 1-
quart jar. 
b. For each pound of a dry tank-mix partner to be applied per acre, add 1.5 teaspoons tspn to the jar. 
c. For each 16 fl oz of a liquid tank-mix partner to be applied per acre, add 0.75 teaspoontspn to the jar. 
d. For each 16 fl oz of 215-18 to be applied per acre, add 0.75 teaspoon tspn to the jar. 
e. After adding all the ingredients, place a lid on the jar and tighten securely. Invert 10 times to mix. 
f. Let the mixture stand for 15 minutes and evaluate the solution for uniformity and stability. Look for 
separation, large flakes, precipitates, gels, heavy oily film on the jar, or other signs of incompatibility. 
If the tank-mix partners are not compatible, do not use the mixture in a spray tank. 
g. After compatibility testing is complete, dispose of any pesticide wastes in accordance with the Storage 
and Disposal section of this label. 
 
D. APPLICATION INSTRUCTIONS 
215-18 must be applied to both emerged weeds and corn. Apply as a broadcast application to provide control of 
emerged weeds as well as residual control of susceptible, emerging weed seedlings. Apply 215-18 by ground and 
refer to Crop-specific Information section for application restrictions. 
 
Make postemergence applications of 215-18 when weeds do not exceed size shown in TABLES 1 and 2 and are 
actively growing. An adjuvant is required for best performance on emerged weeds; refer to Additives section for 
details. Depending on growing conditions, emerged, susceptible weeds may take 14 to 21 days for complete 
control. Herbicidal activity on emerged weeds may be delayed or reduced under extended cloudy and/or cooler 
weather conditions, or when weeds are under drought and/or heat stress conditions.

xxx648-202004212021092820250721819 Page 13 of 22 
 
 
215-18 should be applied a minimum of one hour before rainfall or overhead irrigation. 
 
215-18 provides soil residual control of susceptible weeds. If activating rainfall is not received within 7 days after 
application, residual weed control may be reduced. 
 
Avoid disturbing (e.g., cultivation) treated areas for at least 7 days following an application of 215-18 to allow 
maximum herbicide absorption and weed control. Avoid deep cultivation that will move dormant weed seeds 
upward in the soil where seeds can germinate. 
 
The applicator is responsible for any loss or damage that results from spraying 215-18 in a manner other than 
recommended in this label. 
 
Restrictions: If native plant communities exist within 30 feet downwind of the application, a 30-foot downwind 
spray buffer must be maintained between the application and those native plant communities. The applicator 
must follow all applicable state and local regulations and ordinances regarding spraying. 
 
1. Ground Application Methods and Equipment 
Apply 215-18 with properly calibrated ground equipment in a minimum of 10 or more15 gallons of water per acre. 
Use water volumes of greater than 15 gallons or more per acre per/A when treating larger weeds and/or dense 
weed infestations. Slower application speeds generally result in more uniform coverage of targeted area and 
better performance. 
 
2. Cleaning Spray Equipment 
To avoid injury to sensitive crops, clean all equipment using a strong detergent or commercial sprayer cleaner 
according to the manufacturer’s directions. Triple rinse tanks and spray booms before and after applying this 
product. 
 
After using 215-18 triple rinse the spray equipment, including use of a commercial tank cleaner, before using the 
equipment for a new application. Make sure any rinsate or foam is thoroughly removed from spray tank and 
boom. Rinsate may be disposed following the pesticide disposal directions on this label. 
 
3. Spray Coverage 
Thoroughly cover emerged weeds with spray droplets to achieve optimum and consistent control. Dense leaf 
canopies can prevent adequate spray coverage resulting in poor weed control. Use nozzles and pressures that 
generate medium to coarse size spray droplets (250-400 microns). Use spray volumes which ensure coverage of 
emerged weeds with 215-18 to maximize performance. Avoid using nozzles that produce very coarse, extremely 
coarse or ultra-coarse spray droplets, as this will result in unsatisfactory weed control. 
 
4. Spray Drift Restrictions 
APPLICATORS ARE RESPONSIBLE FOR AVOIDING SPRAY DRIFT AT AND ADJACENT TO THE APPLICATION SITE. 
 
Do not apply when weather conditions favor spray drift to adjacent sensitive crops and vegetation. Spray droplets 
intercepted by susceptible plants from drift may caus e plant injury. Make applications when wind speeds are 
approximately between 2 and 10 mph to avoid spray drift from treated areas. Do not apply when winds are gusty, 
during temperature inversions, or when conditions will favor movement of spray particles away from the desired

xxx648-202004212021092820250721819 Page 14 of 22 
 
spray target. Avoid spraying during conditions of low humidity and/or high temperatures. Consider using 
agriculturally approved drift-reducing additives in accordance with product labels. 
 
Ground application equipment must be properly maintained and calibrated using appropriate carriers. Wind 
speed must be measured adjacent to the application site, on the upwind side, immediately prior to application. 
Sensitive Areas: Apply the pesticide when the potential for drift to adjacent sensitive areas (e.g., residential areas, 
bodies of water, and known habitats for threatened or endangered species, non-target crops) is minimal (e.g., 
when wind is blowing away from the sensitive areas). 
 
Do not apply where possible drift to unprotected persons, or to food, forage, or crops that might be damaged and 
thus rendered unfit for sale, use, or consumption can occur. 
MANDATORY SPRAY DRIFT MANAGEMENT 
Ground Boom Applications: 
x User must only apply with the release height recom mended by the manufacturer, but no more than 4 feet 
above the ground or crop canopy. 
x Applicators are required to select a nozzle and pressure that deliver medium or coarse [PJ1] droplets in 
accordance with American Society of Agricultural & Biological Engineers Standard 572 (ASABE S572). 
x Do not apply when wind speeds exceed 15 miles per hour at the application site. 
x Do not apply during temperature inversions. 
SPRAY DRIFT ADVISORIES 
THE APPLICATOR IS RESPONSIBLE FOR AVOIDING OFF-SITE SPRAY DRIFT. 
BE AWARE OF NEARBY NON-TARGET SITES AND ENVIRONMENTAL CONDITIONS. 
 
IMPORTANCE OF DROPLET SIZE 
An effective way to reduce spray drift is to apply the largest droplets that provide target pest control. While 
applying larger droplets will reduce spray drift, the potential for drift will be greater if applications are made 
improperly or under unfavorable environmental conditions. 
 
Controlling Droplet Size – Ground Boom 
a. Volume - Increasing the spray volume so that larger droplets are produced will reduce spray drift. Use the 
highest practical spray volume for the application. If a greater spray volume is needed, consider using a nozzle 
with a higher flow rate. 
b. Pressure - Use the lowest spray pre ssure recommended for the nozzle to produce the target spray volume 
and droplet size. 
c. Spray Nozzle - Use a spray nozzle that is designed for the intended application. Consider using nozzles designed 
to reduce drift. 
BOOM HEIGHT – Ground Boom 
For ground equipment, the boom should remain level directly above the crop canopy and have minimal bounce. 
 
SHIELDED SPRAYERS 
Shielding the boom or individual nozzles can reduce spray drift. Consider using shielded sprayers. Verify that the 
shields are not interfering with the uniform deposition of the spray on the target area. 
 
TEMPERATURE AND HUMIDITY 
When making applications in hot and dry conditions, use larger droplets to reduce effects of evaporation.

xxx648-202004212021092820250721819 Page 15 of 22 
 
TEMPERATURE INVERSIONS 
Drift potential is high during a temperature inversion. Te mperature inversions are characterized by increasing 
temperature with altitude and are common on nights with limited cloud cover and light to no wind. The presence 
of an inversion can be indicated by ground fog or by the movement of smoke from a ground source or an aircraft 
smoke generator. Smoke that layers and moves laterally in a concentrated cloud (under low wind conditions) 
indicates an inversion, while smoke that moves upward and rapidly dissipates indicates good vertical air mixing. 
Avoid applications during temperature inversions. 
 
WIND 
Drift potential generally increases with wind spee d. AVOID APPLICATIONS DURIN G GUSTY WIND CONDITIONS. 
Applicators need to be familiar with local wind patterns and terrain that could affect spray drift. 
 
E. RESTRICTIONS 
 
x Do Not apply more than 40 fl oz of 215-18 per acre per year. 
x Do Not apply 215-18 to corn which is greater than 11 inches in height. 
x Do Not use liquid fertilizer as a carrier for postemergence applications. 
x Do Not graze or feed treated corn forage, silage, fodder, or grain for at least 45 days after an application 
of this product. 
 
1. Rotational Crop Restrictions 
The following rotational crops may be planted after uniformly applying 215-18 at labeled application rates. Do not 
plant earlier than the specified interval, as crop injury may occur. Avoid over-applications by minimizing overlaps 
of spray swaths and by switching off spray boom when turning (end rows). In the event of a crop loss due to 
weather or other causes, any corn type can be replanted at any time following an application of 215-18. If 215-
18 was tank-mixed with other herbicides, the label replanting restrictions for these herbicides must be followed.

2. Use Restrictions 
This chemical demonstrates the properties and characteristics associated with chemicals detected in ground 
water. The use of this chemical in areas where soils are permeable, particularly where the ground water is shallow, 
may result in ground water contamination. On the following soil types, do not apply this product within 50 feet of 
any well where the depth to ground water is 30 feet or less: sands with less than 3 percent organic matter; loamy 
sands with less than 2 percent organic matter; or sandy loams with less than 1 percent organic matter. See the 
figure for additional clarification. 
This product must not be mixed or loaded or used within 50 feet of any 
wells (including abandoned wells and drainage wells), sink holes, 
perennial or intermittent streams and rivers, natural or impounded lakes 
and reservoirs. This setback does not apply to properly capped or plugged 
abandoned wells and does not apply to impervious pad or properly diked 
mixing/loading areas. 
 
Operations that involve mixing, loading, rinsing, or washing of this 
product into or from pesticide handling or application equipment or 
containers within 50 feet of any well are prohibited unless conducted on 
an impervious pad constructed to withstand the weight of the heaviest 
load that may be positioned on or moved across the pad. Such a pad shall 
be designed and maintained to contain any product spills or equipment 
leaks, container or equipment rinse or washwater, and rainwater that 
may fall on the pad. Surface water shall not be allowed to either flow over 
or from the pad, which means the pad must be self-contained. The pad 
shall be sloped to facilitate material removal. An unroofed pad shall be of 
sufficient capacity to contain at a minimum 110 percent of the capacity 
of the largest pesticide container or application equipment on the pad. A 
pad that is covered by a roof of sufficient size to completely exclude 
precipitation from contact with the pad shall have a minimum containment capacity of 100 percent of the capacity

xxx648-202004212021092820250721819 Page 17 of 22 
 
of the largest pesticide container or application equipment on the pad. Containment capacities as described above 
shall be maintained at all times. The above-specified minimum containment capacities do not apply to vehicles 
when delivering pesticide shipments to the mixing/loading sites. States may have in effect additional requirements 
regarding well head setbacks and operational area containment. 
 
Do not flood irrigate to apply or incorporate this product. 
 
Product must be used in a manner that will prevent back siphoning into wells, spills or improper disposal of excess 
pesticide, spray mixtures or rinsates. 
 
Do not apply this product through any type of irrigation system, unless otherwise directed by approved 
supplemental labeling in possession of the user at the time of application. 
 
Disposal of excess pesticide, spray mixtures or rinsate should be according to label use instructions or according 
to the State Pesticide or Environmental Control Agency or the Hazardous Waste representative at the nearest EPA 
regional office. 
 
Do not apply under conditions that favor runoff or wind erosion of soil containing this product to non-target areas.

these conditions, the soil surface should first be settled by rainfall or irrigation. 
Do not apply to impervious substrates such as paved or highly compacted surfaces or frozen or 
snow covered soils. 
 
Do not use tailwater from the first flood or furrow irrigation of treated fields to treat non-target crops 
unless at least 1/2 inch of rainfall has occurred between application and the first irrigation. 
 
Do not apply this product using aerial application equipment, unless otherwise directed by approved 
supplemental labeling in possession of the user at the time of application. 
 
Do not apply when wind conditions favor drift to non-target sites. To minimize spray drift to non-target areas: 
 
Use low-pressure application equipm ent capable of producing a large droplet spray. Do not use nozzles 
that produce a fine droplet spray. Minimize drift by using sufficient spray vo lume to ensure adequate 
coverage with large droplet size sprays. 
 
Keep ground driven spray boom as low as possible above the target surface. 
 
Make application when the wind velocity favors on-target product deposition (approximately 3 to 10 miles 
per hour). Do not apply when wind velocity exce eds 15 miles per hour. Avoid application when gusts 
approach 15 miles per hour. 
 
Low humidity and high temperatures increase the likelihood of spray drift to sensitive areas. Avoid 
spraying during conditions of low humidity and/or high temperatures. Do not apply during inversion 
conditions. 
 
Use of this product not consistent with this label may result in injury to ·persons, animals or crops, or other

F. CROP-SPECIFIC USE DIRECTIONS 
215-18 is for use in corn only. 215-18 may be applied for control of emerged weeds and residual control of 
susceptible, emerging weed seedlings after crop planting. Target application to broadleaf and grass weeds which 
do not exceed the maximum size shown in TABLES 1 and 2 under Product Information section. 
 
1. Corn (field corn, seed corn, popcorn) 
215-18 may be applied to field corn, seed corn and popcorn including both conventional and herbicide-resistant 
hybrids of these corn types. Apply from corn emergence up to 11-inch tall corn. 
 
215-18 may be used in tank mixtures or sequential applications with other products that are registered for use in 
corn. If 215-18 is tank mixed with other herbicides, follow the label restrictions for the most restrictive of the tank-
mix products. Ensure that the respective tank-mix products are registered for use on the specific corn types being 
treated, as not all corn products are registered on seed corn and popcorn. 
 
2. Application Rates 
215-18 application rate varies by soil texture and percent organic matter as specified in TABLE 3. Follow rate 
ranges listed in this table for best control of emerged weeds and germinating weeds after application. Up to two 
sequential applications of 215-18 may be made during a growing season. Applications must be separated by 14 
days or more and must not exceed a cumulative total of 40 fl oz/A per year.

3. Application Timing 
x Field Corn and Popcorn – 215-18 may be applied from spike stage of corn up to 11-inch tall corn. 
x Preharvest Interval (PHI) – Do not make applications to field corn or popcorn within 45 days of corn 
harvest (silage, fodder or grain). 
 
4. Tank Mixes 
215-18 may be tank mixed or applied sequentially to corn with other herbicides to broaden the spectrum of weed 
control and/or extend the length of residual control. Atra zine (Photosystem II inhibitor, Group 5 herbicide) is 
known to enhance the activity of herbicides containing an HPPD-inhibitor (Group 27) such as 215-18. Atrazine may 
be tank mixed with 215-18 at 0.25 to 0.5 lb active atrazine per acre for enhanced control of emerged broadleaf 
and grass weeds. Higher rates of atrazine will provide additional residual weed control. To enhance control of 
emerged grass weeds, 215-18 herbicide may be tank-mixed with glyphosate-containing herbicides. Follow 
adjuvant recommendations specified in the ADDITIVES section of this label. 
 
5. Sequential Uses 
215-18 may be applied at rates specified in TABLE 3 as the second pass in a planned two-pass sequential program 
in corn. If using other acetochlor-containing herbicides in a sequential program, do not apply more than 3 lb active 
of acetochlor per acre during the season. 
 
When applied in the second pass, reduced rates of Impact Core may be tank mixed with other postemergence 
herbicides, including but not limited to, Impact, ImpactZ, Sinate, glyphosate and glufosinate for broader spectrum 
control of emerged weeds. 
 
If using other acetochlor-containing herbicides in a sequential program, do not apply more than 3 lb active of 
acetochlor per acre during the season. If using other topramezone-containing herbicides in a sequential program, 
do not apply more than 0.044 lb active of topramezone per acre during the season.

xxx648-202004212021092820250721819 Page 20 of 22 
 
 
6. Crop Tolerance 
Apply 215-18 during favorable growing conditions for optimum crop tolerance and weed control. Avoid making 
applications during or following an extended period of cloudy days and cool night temperatures when crop is not 
actively growing. Crops under stressful growing conditions are more likely to show injury response from any 
herbicide application. Rarely, corn plants under stressful growing conditions and treated with 215-18 may show 
transient leaf bleaching. Leaf burn necrosis can also occur under warm, humid conditions at application. Use of 
additional herbicides and/or oil-based adjuvants in the tank mixture may increase potential for foliar burnnecrosis. 
These symptoms are infrequent and temporary; crop growth and development are not affected.
