ENVIRONMENTAL HAZARDS
This pesticide is toxic to fish and invertebrates. Do not appl y 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 cleaning equipment or disposing of
equipment washwaters or rinsate.
This product may contaminate water through drift of spray in wind. This product has a potential for runoff for several
months or more after application. Poorly drained soils and soil s with shallow water tables are more prone to produce runoff
that contains this product. A level, well maintained vegetati ve buffer strip between areas to which the product is applied
and surface water features such as ponds, streams, and spring s will reduce the potential for contamination of water from
rainfall-runoff. Runoff of this product will be reduced by avoidi ng applications when rainfall is forecasted to occur within 48
hours. Sound erosion practices will reduce this product's contribution to surface water contamination.

PHYSICAL AND CHEMICAL HAZARDS
Combustible. Keep away from heat, sparks, and open flames. Keep container closed

ENVIRONMENTAL CONDITIONS AND BIOLOGICAL ACTIVITY
ASSURE II is a systemic herbicide that is rapidly absorbed by treated foliage and translocated to the roots and other growing
points of the plant. When affected, younger plant tissues become chlorotic/necrotic and eventually die, leaving treated plants
stunted and noncompetitive. In general, these symptoms are first observed within 7 to 14 days after application depending on the
grass species treated and the environmental conditions.
The degree of control and duration of the effect of ASSURE II depend upon the rate used, weed spectrum, weed size and
variability, growing conditions at and following treatment, soil moisture, precipitation, tank mixtures, and spray adjuvant used.

Conditions conducive to healthy, actively growing plants optimi ze the performance of ASSURE II. Unacceptable control may
occur if ASSURE II is applied to grasses stressed from:
x abnormal weather (excessive heat or cold, or widely fluctuating temperatures),
x hail damage,
x drought,
x water saturated soils,
x mechanical injury, or
x prior herbicide injury.
Grasses under these conditions are often less susceptible to herbicide activity. Delay application until the stress passes and
weeds and crop resume growth.
Allow the crop to fully recover and resume normal growth before applying ASSURE II to crops previously stressed or injured
from other pesticide applications.
ASSURE II is rainfast 1 hour after application.

APPLICATION INFORMATION
USE RESTRICTIONS
x Do not feed forage, hay, or straw from treated areas to livestock unless stated otherwise under the specific crop use
directions.
x Do not apply ASSURE II through any type of irrigation equipment.
x Do not contaminate any body of water.
x Do not use on lawns, walks, driveways, tennis courts, or similar areas.
IMPORTANT PRECAUTIONS
Injury to or loss of desirable trees, vegetation, or adjacent susceptible crops may result from failure to observe the following:
x Prevent drift of spray to desirable plants (refer to SPRAY DRIFT MANAGEMENT section of this label).
x Take all necessary precautions to avoid all direct or indirect contact (such as spray drift) with non-target plants or areas.
Most grass crops, including wheat, barley, rye, oats, sorghum, rice, and corn are highly susceptible to ASSURE II.
x Carefully observe all sprayer cleanup instructions both prior to and after using this product, as spray tank residue may
damage crops other than those included in the crop rotation section.
WEED RESISTANCE MANAGEMENT
ASSURE II herbicide contains the acti ve ingredient quizalofop-p-ethyl and is a group 1 herbicide based on the mode of
action classification system of the Weed Science Society of America. Quizalofop-p-ethyl is in th e class of herbicides known as
aryloxphenoxypropionates (FOPs) within the group 1 herbicides that inhibit the enzyme acetyl-CoA carboxylase (ACCase) in
weeds.
Proactively implementing diversified weed control strategies to minimize selection for weed populations resistant to one or
more herbicides is a best practice. A diversified weed manage ment program may include the use of multiple herbicides with
different sites of action and overlapping weed spectrum with or without tillage operations and/or other cultural practices.
Research has demonstrated that using full-labeled rates and di rections for use is important to delay the selection for
resistance.
The continued effectiveness of this product depends on the successful implementation of a weed resistance management
program.
To aid in the prevention of developing weeds resistant to this product, users should:
x Scout fields before application to ensure herbicides and rates will be appropriate for the weed species and weed sizes
present.

Page 5 of 26
x Start with a clean field, using either a burndown herbicide application or tillage.
x Control weeds early when they are relatively small (less than 4 inches).
x Apply full rates of ASSURE II herbicide for the most difficult to control weeds in the field at the specified time
(correct weed size) to minimize weed escapes.
x Scout fields after application to detect weed escapes or shifts in control of weed species.
x Control weed escapes before they reproduce by seed or proliferate vegetatively.
x Report any incidence of non-performance of this product against a particular weed to your AMVAC representative,
local retailer, or county extension agent.
x Contact your AMVAC representative, crop advisor, or extension agent to find out if suspected resistant weeds to this
MOA have been found in your region. If resistant biotypes of target weeds have been reported, use the application
rates of this product specified for your local conditions. Tank mix products so that there are multiple effective sites of
actions for each target weed.
x If resistance is suspected, treat weed escapes with an he rbicide having a site of acti on other than group 1 and/or use
nonchemical methods to remove escapes, as practical, with the goal of preventing further seed production.
x Suspected herbicide-resistant weeds may be identified by these indicators:
x Failure to control a weed species normally controlled by the herbicide at the dose applied, especially if control is
achieved on adjacent weeds;
x A spreading patch of non-controlled plants of a particular weed species; and
x Surviving plants mixed with controlled individuals of the same species
Additionally, users should follow as many of the following herbicide resistance management practices as is practical:
x Use a broad-spectrum soil-applied herbicide with other sites of action as a foundation in a weed control program.
x Utilize sequential applications of herbicides with alternative sites of action.
x Rotate the use of this product with non-group 1 herbicides.
x Avoid making more than two applications of ASSURE II herbicide and any ot her group 1 herbicides within a single
growing season unless mixed with an herbicide with a different site of action with an overlapping spectrum for the
difficult-to-control weeds.
x Incorporate non-chemical weed control practices, such as mechanical cultiv ation, crop rotation, cover crops and
weed- free crop seeds, as part of an integrated weed control program.
x Use good agronomic principles that enhance crop development and crop competitiveness.
x Thoroughly clean plant residues from equipment before leaving fields suspected to contain resistant weeds.
x Manage weeds in and around fields, during and after harvest to reduce weed seed production.
INTEGRATED PEST MANAGEMENT
This product may be used as part of an Integrated Pest Mana gement (IPM) program that can include biological, cultural, and
genetic practices aimed at preventing economic pest damage. IPM principles and practices include field scouting or other
detection methods, correct target pest identification, popula tion monitoring, and treating when target pest populations
reach locally determined action thresholds. Consult your state cooperative extension service, professional consultants or
other qualified authorities to determine appropriate action treatment threshold levels for treating specific pest/crop systems
in your area.
TANK MIXES
It is the pesticide applicator’s responsibility to ensure that all products are registered for the intended use. Read and
follow the applicable restrictions and limitations and directions for use on all product labels involved in tank mixing.
Applicators must read and follow the most restrictive directions for use, precautions, and limitations of each product
in the tank mixture.
Refer to the labels of all tank mix products for information regarding use information (such as rates, timing, application
information, and sprayer cleanup) and product precautions and restrictions (especially adjuvants - ASSURE II requires the
use of an adjuvant). The most restrictive provisions apply. If those instructions conflict with this label, do not tank mix the
herbicide with ASSURE II.
AMVAC also recommends that you first consult your state expe riment station, university, or extension agent, Agricultural
dealer, or AMVAC representative as to the potential for any adverse interactions (resulting in unacceptable grass control
and/or crop injury) before using new herbicid e, insecticide and fungicide mixtures. If no information is available, limit the
initial use of ASSURE II and the new herbicide, insecticide or fungicide product to a small area.

Page 6 of 26
Tank Mix Compatibility Testing
Always conduct a jar test to evaluate physical compatibility of ASSURE II and other pesticides before applying a particular
mixture to listed crops for the first time. Use a clear glass quar t jar with lid and mix the tank mix ingredients in their rela tive
proportions. Invert the jar containing the mixture several time s and observe the mixture for approximately 1/2 hour. If the
mixture balls-up, forms flakes, sludges, gels, oily film or layers, or other precipitates, it is not compatible.
Application with Insecticides and Fungicides
ASSURE II may be tank mixed with postemergence fungicides, in secticides and bactericides registered for use in the specific
crop.
Application with Broadleaf Herbicides
For best results, apply ASSURE II alone or in sequenc e with broadleaf herbicide(s). Under arid or stressful environmental
conditions, tank mixtures with broadleaf herbicides may reduce control of some grass species. Activity of the postemergence
broadleaf herbicide in the tank mixture is not affected.
Split Applications with Postemergence Broadleaf Herbicides
ASSURE II applied immediately prior to or following an ap plication of a postemergence broadleaf herbicide may reduce
control of some grasses. For best results apply ASSURE II at least 1 day before or 7 days after postemergence broadleaf
herbicides.

SPOT/SMALL AREA SPRAY INSTRUCTIONS
To spot treat small areas of annuals (i.e., volunteer corn) or perennials (i.e., rhizome johnsongrass)
Use a 0.375% volume/volume (v/v) solution of ASSURE II and water.

SPRAY VOLUMES FOR SMALL AREAS

x Include a phytobland crop oil concentrate at 1 gallon per 100 gallons of spray solution (1% v/v) or a nonionic
surfactant at 1 qt per 100 gallons of spray solution (0.25% v/v).
x Treat plants on a spray-to-wet basis to ensure good coverage.
x Do not treat >10% of the total treated area as spot/sma ll area treatment. Do not exceed the maximum specified
rate/acre/season for the crop that is going to be planted when additional applications are made as spot treatment
or small area treatment.
Cultivation
A timely cultivation may be necessary to control suppressed weeds, weeds that were beyond the maximum size at application, or
weeds that emerge after an application of ASSURE II.

Cultivation up to 7 days before the postemergence application of ASSURE II may decrease weed control by pruning weed roots,
placing the weeds under stress, or covering the weeds with soil and preventing coverage by ASSURE II .
Optimum timing for cultivation is 7 - 14 days after a postemergence application of ASSURE II.

Agricultural Uses
ASSURE II herbicide is a selective herbic ide that controls annual and perennial grasses in canola, carinata, crambe, cotton
(cottonseed subgroup 20C), crops grown for seed, eucalyptus, d ry beans (including Chickpea), dry and succulent peas, flax
(flaxseed), fruit, pome crop group 11-10 (except New York state), fruit, small vine climbing, except fuzzy kiwifruit crop
subgroup 13-07F (except New York state), fruit, stone crop gr oup 12-12 (except New York state), hybrid poplar plantings,
lentils, mint (spearmint and peppermint), pennycress, pinea pple, rapeseed subgroup 20A (inc ludes borage, canola, crambe,
gold of pleasure [camelina], cuphea, echium, Hare's ear mustard, oil radish, poppy seed, rapeseed, sesame, sweet rocket,
cultivars, varieties, and/or hybrids of these), ryegrass grown for seed, snap beans, INZEN™ A II grain sorghum, soybeans,
sugarbeets, sunflower (subgroup 20B), Enlist™ field corn and non-crop areas. ASSURE® II is also registered for control of annual
and perennial grasses in alfalfa, onion, carrot, garlic, Swiss chard, spinach, radish, Chinese cabbage, and red beets grown
specifically under contract as non-food/non feed crops for seed production only.

Page 7 of 26

ASSURE II does not control sedges or broadleaf weeds. ASSURE II controls the grasses listed in the “Weeds Controlled and rate
Selection” chart when applied at specified rates and timings. ASSURE II will control emerged grasses. Subsequent flushes of
grasses require additional treatment. See "use restrictions" portion of the label before using. Follow all use directions and
restrictions listed for the specific crop.

Non-Agricultural Uses
Non-Crop Areas
ASSURE II is registered for postemergence control of certain grasses on non-crop sites including fence rows, roadsides and
equipment storage areas.
x Apply by ground application equipment only.
x DO NOT apply by aerial application.
x For paved areas, apply as spot/small area treatments only (see Spot/Small Area Spray instructions section).
x Make a single application of ASSURE II at a rate of 12 to 16 fl oz/A (0.083 - 0.11 lb ai/A) to actively growing grasses.
Non-Crop Areas - to aid in establishment of Wildflowers
x Since ASSURE II controls many grasses but not most broadleaf plants, it may be used to enhance establishment and
growth of certain broadleaf plants on non-crop sites (that is , plants identified as “wildflowers” such as indian blanket,
cone flowers, bachelor button, dwarf co rnflower, coreopsis, white yarrow, oxey e daisy, dames-rocket, blue flax,
evening primrose, blackeyed-susan, marigold, impatiens, bluebonnet, Indian paintbrush, verbena, gaillardia,
chrysanthemum, catchfly and scarlet pimpernel).
x Make a single application of ASSURE II at a rate of 5 to 12 fl oz/A (0.034 - 0.083 lb ai/A). Refer to the ‘’ Weeds
Controlled and Rate Selection’’ table for specific application rates. Do not apply more than 12 fl oz/A (0.083 lb ai/A)
per year.
Application Timing


Sequential Applications
Do not exceed the maximum use rates listed under the directions for each specific crop.
Annual Grasses
In the event of a subsequent flush of grass, or regrowth of pr eviously treated grass occurs, a second application of ASSURE II
may be applied unless stated otherwise. Select the appropriat e rate for the grassy weed from the “Weeds Controlled - rate
selection” chart.
Perennial Grasses
If perennial grasses regrow, reapply ASSURE II at 6-7 fl oz/A of product, unless stated otherwise. Do not exceed the
maximum use rates listed under each crop.
Spray Adjuvants
Applications of ASSURE II must include either a crop oil concentrate or a nonioni c surfactant. Consult local AMVAC fact
sheets, technical bulletins, and service policies prior to using ot her adjuvant systems. If another herbicide is tank mixed wit h
ASSURE II to increase the weed spectrum, select adjuvants authorized for use with both products. Products must contain
only EPA-exempt ingredients.
Petroleum Crop Oil Concentrate (COC)
x Petroleum-based crop oil concentrates are the most effective adjuvant type with ASSURE II.
x Apply petroleum-based crop oi l concentrate at 1% v/v (1 gallon per 100 gallons spray solution) or 2% under arid
conditions. Note – In soybean and sunflower, up to 2% v/v may be used based on local recommendations.
x Oil adjuvants must contain at least 80% phytobland, petroleum (mineral) or modified vegetable seed oil with at least
15% surfactant emulsifiers.
x For aerial application apply 0.5% v/v (2 quarts product per 100 gallons spray solution).
Nonionic Surfactant (NIS)
x Apply at 0.25 % v/v (1 quart of product per 100 gallons spray solution).
Crop and Non-Crop Uses
Apply ASSURE II to young, actively growing grasses according to th e rate chart that follows. If a field is to be irrigated, app ly
ASSURE II after the irrigation. Applications made to grasses that are larger than the sizes listed in the rate charts or to
grasses under stress may result in unsatisfactory control.

Page 8 of 26
x Surfactant products must contain at least 80% nonionic surfactant.
Ammonium Nitrogen Fertilizer
x An ammonium nitrogen fertilizer may be added to the spra y mixture, in addition to crop oil concentrate or nonionic
surfactant, but is not required to optimize performance of this product.
x Use 2 quart/A of a high-quality urea ammonium nitrate (UAN), such as 28%N or 32%N, or 2 lb/A of a spray-grade
ammonium sulfate (AMS). Use 4 qt/A UAN or 4 lb/A AMS under arid conditions.
x Do not use liquid nitrogen fertilizer as the total carrier solution.
Special Adjuvant Types
x Combination adjuvant products may be used at doses that provide the required amount of NIS, COC, MSO and/or
ammonium nitrogen fertilizer. Consult product literature for use rates and restrictions.
x In addition to the adjuvants specified above, other adjuvant types may be used if they provide the same functionality
and have been evaluated and approved by AMVAC Product Development.

1Avoid using Assure II as the primary form of weed control on johnsongrass ( Sorghum halepense ) and shattercane
(Sorghum bicolor) in INZEN A II grain sorghum. The use of a second MOA or manual removal is strongly encouraged on
these weeds in INZEN A II grain sorghum to ensure that polle n-mediated gene flow does not occur between quizalofop-P-
ethyl tolerant sorghum and shattercane or johnsongrass.

Specific Weed Problems
Volunteer Glyphosate-Resistant Corn
ASSURE II may be used for control of volunteer glyphosate resist ant corn in other glyphosate resistant crops. For control of
other weeds, it may be tank mixed with glyphosate as follows:
x Apply ASSURE II at a rate of 4 fl oz/A for up to 12 inch volunteer corn, 5 fl oz/A for 12- 18 inch corn and 8 fl oz/A
ASSURE II for 18-30 inch corn, tank mixed with a labeled rate of glyphosate.
x A nonionic surfactant or petroleum based crop oil concentrate adjuvant must be included. Refer to the Spray
Adjuvants section in this label for adjuvant preference, rates, and additional use information.
Rhizome Johnsongrass - South East States
For control of rhizome johnsongrass in the states of Alabama, Arkansas, Florida, Georgia, Loui siana, Maryland, Mississippi,
Tennessee, Virginia, and West Virginia, a reduced rate of ASSURE II may be used if applied in a sequential application
program as follows:
1. Apply ASSURE II at 5 fl oz/A when johnsongrass is 10-24 inches tall.
2. Apply ASSURE II a second time at 5 fl oz/A wh en johnsongrass regrowth is 6-10 inches tall.
Do not apply ASSURE II in a tank mix with postemergence broadleaf herbicides when using this reduced rate, sequential
application program. Do not exceed the ma ximum specified rate/acre/season for the crop that is going to be planted when
additional applications are made to control rhizome johnsongrass.
Rhizome Johnsongrass
ASSURE II herbicide will provide control of weeds in fallow, including emerged rhizome and seedling Johnsongrass. Note
that, when applied at specified rates and timings to control grass weeds, ASSURE II herbicide will provide control of emerged
grasses only. Subsequent flushes of grasses require additional treatment.
Apply ASSURE II herbicide for control of seedling and rhizome Johnsongrass at the range indicated.
x Apply ASSURE II at 8 fl oz/A when seedling johnsongrass is 2 - 6 inches tall.
x Apply ASSURE II at 12 fl oz/A when rhizome johnsongrass is 12-16 inches tall.
x If rhizome Johnsongrass regrows, reapply ASSURE II at 8 fl oz/A when Johnsongrass regrowth is 6-10 inches in height.
Tank mixes of ASSURE II with postemergence broadleaf herbicides may result in reduced grass control. If grass control is
reduced, an additional application of ASSURE II ma y be required after grass plants begin regrowth.

ASSURE II herbicide can be tank mixed with bentazon herbicide for selective postemergence weed
control
 of annual and perennial grasses and broadleaf weeds.
When tank mixing ASSURE II with bentazon, annual grass antagonism can be reduced by increasing
the specified use rate of ASSURE II by at least 2 fl oz/A. Refer to specific crop use directions for
maximum use rates.
ASSURE II requires the use of crop oil concentrate or nonionic surfactant adjuvants. Refer to
bentazon labels for application information and restric tions. The most restrictive provisions on either
label apply. Do not use the tank mix if any restrictions on the bentazone label conflict with instructions
on the ASSURE II label. Do not tank mix ASSURE II and adjuvants with bentazon when temperatures

Enlist Field Corn- These directions are for use only on Enlist field corn. Information on crop varieties containing this trait
may be obtained from your seed supplier.
In-Field Buffer:
The applicator must always maintain a 36-foot, downwind buffer between the last treated row and the nearest downwind
field edge (in the direction the wind is blowing).The following areas may be included in the buffer distance calculation when
directly adjacent to the treated field edge(s):
x Roads, paved or gravel surfaces.
x Planted agricultural fields (except crops listed in the "Susceptible plants" section).
x Agricultural fields that have been prepared for planting.
x Areas covered by the footprint of a building, shadehouse, g reenhouse, silo, feed crib, or other man-made structure
with walls and/or a roof.
To maintain the required downwind buffer zone:
x Measure the wind direction prior to the start of any swath that is within 36 feet of a sensitive area.
x No application swath can be initiated in or into an area that is within 36 feet of a sensitive area if the wind direction is
towards the sensitive area.
Susceptible Plants:
Do not apply under circumstances where spray drift may occur to food, forage, or other plantings that might be damaged or
crops thereof rendered unfit for sale, use or consumption. Do not allow contact of herbicide with foliage, green stems,
exposed non-woody roots of crops, desirable plants; including tr ees, because severe injury or destruction may result. Small
amounts of spray drift that may not be visible may injure suscep tible plants. Most grass crops, including wheat, barley, rye,
oats, sorghum, rice, and non - Enlist corn are highly sens itive to ASSURE II. Before making an application, please refer to
your state’s sensitive crop registry (if available) to identify any commercial specialty or certified organic crops that may be
located nearby.
Resistance Management for Enlist Field Corn:
The following steps are provided to aid in the prevention of developing weeds resistant to this product:
x Scout field before application to ensure herbicides and rates will be appropriate for the weed species and weed sizes
present.
x Apply the maximum specified labeled use rate of this product for the most difficult to control weed in the field at the
specified time (correct weed size) to minimize weed escapes.
x Scout field after application to detect weed escapes or shifts in weed species.
x Report any incident of non-performance of this product on a targeted weed species to your AMVAC retailer,
representative, or call 1-888-462-6822
x If resistance is suspected in targeted weed species, treat weed escapes with an herbicide having a mechanism of
action other than group 1 and/or use non-chemical methods to remove escapes, as practical, with the goal of
preventing further seed production. Report suspected resistance to your AMVAC retailer, representative,
or call 1-888-462-6822.
Suspected Resistance: Indicators of suspected herbicide resistance incl ude (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
uncontrolled plants of a particular weed species; and (3) su rviving plants mixed with controlled individuals of the same
species. Likely resistant weeds are assumed to be present if any of these criteria are met.
Additionally, users should follow as many of the following herbicide-resistance management practices as practicable:
x Use a broad-spectrum, soil-applied herbicide with other mechanisms of action as a foundation in a weed control
program.
x Utilize sequential applications of herbicides with alternative mechanisms of action.
x Rotate the use of this product with non-group 1 herbicides.
x Incorporate non-chemical weed control practices, such as mechanical cultivation, crop rotation, cover crops, and
weed- free crop seeds, as part of an integrated weed control program.

Page 16 of 26
x Thoroughly clean plant residues from equipment before leaving fields suspected to contain resistant weeds.
x Avoid using any other group 1 herbicides within a sing le growing season unless in conjunction with another
mechanism- of-action herbicide with overlapping spectrum.
x Manage weeds in and around fields, during and after harvest to reduce weed seed production.
Contact your local sales representative, crop advisor, or extens ion agent to find out if suspected resistant weeds to group 1
herbicides have been found in your regions. If resistant biotyp es of target weeds have been reported, use the application
rates of this product specified for your local conditions. Tank mix products so that there are multiple effective mechanisms of
action for each target weed.
Tank Mixing:
x For use on Enlist corn, do not tank mix this product with an y other pesticide product(s) without first consulting the
website at www.EnlistTankMix.com/ASSUREII. This website contains a list of pesticide active ingredients that are
currently prohibited from tank mixing with this product. When tank mixing this product, only use pesticide product(s)
that: 1) are registered for the intended use site, application method, and timing; 2) do not prohibit tank mixing; and 3)
do not contain one of the prohibited pesticide active ingredients listed on www.EnlistTankMix.com/ASSUREII.
x Mixers, applicators, and other handlers of this product must consult the we bsite within one week prior to application
in order to comply with the most up-to-date information on tank mix partners.

APPLICATION EQUIPMENT
See SPRAY DRIFT MANAGEMENT section for additional information and precautions.
Ground Application
Broadcast Application
x When applying by ground, use spray nozzles that will deliv er medium or larger spray droplets as defined in the
American Society of Agricultural and Biological Engin eers (ASABE) standard ANSI/ASAE S572.1 (March 2009). (See
Spray Drift Management section for additional information).
x Use flat fan or hollow cone nozzles at 25-60 psi.
x Do not use flood, rain drop, whirl chamber, or any other nozzle types that produce coarse, large spray droplets. In
addition, do not use controlled droplet applicator (CDA) type nozzles as poor weed control or excessive spray drift
may result.
x Use a minimum of 10 gal/A of water in non-arid areas.
x Use a minimum of 15 gal/A of water in arid areas.
x For all crops except pineapple: Do not exceed 40 gal of wate r per acre. Refer to pineapple section for specified spray
water volumes.
x Increase spray volume and pressure as weed or crop density and size increase.
Band Application
x Because band application equipment sprays a narrower ar ea than broadcast application equipment, calibrate
equipment to use proportionately less spray solution.
x To avoid crop injury, carefully calibrate the band applicator not to exceed the labeled rate.
x Carefully follow the manufacturer’s instructions for nozzle type, nozzle orientation, distance of the nozzles from the
crop and weeds, spray volumes, calibration, and spray pressure.

Aerial Application
x Use spray nozzles that will deliver coarse or larger spray drop lets as defined in the American Society of Agricultural
and Biological Engineers (ASABE) standard ANSI/ASAE S572.1 (March 2009). (See Spray Drift Management section for
additional information).
x Use nozzle types and arrangements that provide op timum spray distribution and maximum coverage.
x Use a minimum of 3 gal of water per acre in non-arid areas.
x Use a minimum of 5 gal of water per acre in arid areas.
MIXING INSTRUCTIONS
1. Fill the tank 1/4 to 1/3 full of water.
2. While agitating, add the required amount of ASSURE II. If ASSURE II and a tank mix partner are to be applied
together, consult the tank mix partner label for information on which should be added first (normally granules and
powders are added first).
3. Continue agitation until the ASSURE II is fully dispersed, at least 5 minutes.
4. Once the ASSURE II is fully disp ersed, maintain agitation and continue filling tank with water.
5. As the tank is filling, add the required volume of spray additives, always add these to the spray tank last.
6. Apply ASSURE II spray mixture within a reasonable period of time of mixing to avoid product degradation (24 to 48
hrs). If the spray mixture stands for any period of time, thoroughly re-agitate before using.
SPRAYER CLEANUP
The spray equipment must be cleaned before ASSURE II is sprayed. Follow the cleanup procedures specified on the labels of
the previously applied products. If no directions are provided, follow the six steps outlined in After Spraying ASSURE II. It i s
very important that any buildup of dried pesticide deposits wh ich have accumulated in the application equipment be
removed prior to spraying ASSURE II. Steam-cleaning spray tanks to facilitate the removal of any caked deposits of
previously applied products will help prevent accidental crop injury.
After Multiple Loads of ASSURE II herbicide
At the end of each day after multiple loads of ASSURE II herbic ide are applied, rinse the interi or of the tank with fresh water
and then partially fill to flush boom and hoses. This will preven t the buildup of dried pesticide deposits which can accumulate
in the application equipment.

Page 19 of 26
After Spraying ASSUREയIIയand Before Spraying Susceptible Crops and Crops Other Than Those Listed in the Crop
Rotation Section


x Drain tank; thoroughly rinse spray tanks, boom, and hoses with clean water. Loosen and physically remove any visible
deposits.
x Fill the tank with clean water and 1 gal of household ammonia* (contains 3% active) for every 100 gal of water. Flush the
hoses, boom, and nozzles with the cleaning solution. Then add more water to completely fill the tank. Circulate the
cleaning solution through the tank and hoses for at least 15 mi n. Flush the hoses, boom, and nozzles again with the
cleaning solution, and then drain the tank.
x Remove the nozzles and screens and clean separately in a bucket containing cleaning agent and water.
x Repeat step 2.
x Rinse the tank, boom, and hoses with clean water.
x If only Ammonia is used as a cleaner, the rinsate solution may be applied back to the crop(s) recommended on this label. Do
not exceed the maximum labeled use rate. If other cleaners are used, consult the cleaner label for rinsate disposal
instructions. If no instructions are given, dispose of the rinsate on site or at an approved waste disposal facility.
*Equivalent amounts of an alternate-strength ammonia solution or an AMVAC-approved cleaner can be used in the cleanout
procedure. Carefully read and follow the individual cleaner in structions. Consult your Ag dealer, applicator, or AMVAC
representative for a listing of approved cleaners.
Notes:
x CAUTION: Do not use chlorine bleach with ammonia as dangerous gases will form. Do not clean equipment in an
enclosed area.
x Steam-cleaning spray tanks is recommended prior to pe rforming the above cleanout procedure to facilitate the
removal of any caked deposits.
x When ASSURE II is tank mixed with other pesticides, all cleanout procedures should be examined and the most
rigorous procedure should be followed.
x In addition to this cleanout procedure, all precleanout guidelines on subsequently applied products should be
followed as per the individual labels.
x Where routine spraying practices include shared equipm ent frequently being switched between applications of
ASSURE II and applications of other pesticides to ASSURE II-sensitive crops during the same spray season, it is
recommended that a sprayer be dedicated to ASSURE II to further reduce the chance of crop injury.
SPRAY DRIFT MANAGEMENT
The interaction of many equipment and weather-related factors determines the potential for spray drift. The applicator is
responsible for considering all these factors when making application decisions.
AVOIDING SPRAY DRIFT IS THE RESPONSIBILITY OF THE APPLICATOR.
Importance of Droplet Size
The most effective way to reduce drift potential is to apply coar se or larger spray droplets as defined by the ASABE standard
ANSI/ASAE S572.1 (March 2009). The best drift management strate gy is to apply the largest dr oplets that provide sufficient
coverage and control. The presence of sensitive species nearby, the environmental conditions, and pest pressure may affect
how an applicator balances drift control and coverage. APPLYING LARGER DROPLETS REDUCES DRIFT POTENTIAL, BUT WILL
NOT PREVENT DRIFT IF APPLICATIONS ARE MADE IMPROPER LY OR UNDER UNFAVORABLE ENVIRONMENTAL CONDITIONS!
See Wind, Temperature and Humidity, and Temperature Inversions sections of this label.
Controlling droplet Size - Ground Boom
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.
Pressure - use the lowest spray pressure recommended for the nozzle to produce the target spray volume and droplet size.
Spray Nozzle - use a spray nozzle that is designed for the intended application. Consider using nozzles designed to reduce
drift.
Controlling droplet Size - aircraft
To avoid subsequent injury to desirable crops, thoroughly clean all mixing and spray equipment immediately following
applications of ASSURE II as follows:

Page 20 of 26
Number of Nozzles - using the minimum number of nozzles with the highest flow rate that provide uniform coverage will
produce a coarser droplet spectrum.
Nozzle Orientation - orienting nozzles in a manner that minimizes the effects of air shear will produce the coarsest droplet
spectra. For some nozzles such as solid stream, pointing the no zzles straight back parallel to the airstream will produce a
coarser droplet spectrum than other orientations.
Nozzle Type - Solid stream nozzles (such as disc and core with sw irl plate removed) or other low drift nozzles produce the
coarsest droplet spectra.
Pressure - Selecting the pressure that produces the coarsest droplet spectrum for a particular nozzle and airspeed reduces
spray drift potential. For some nozzle types such as solid st reams, lower pressures can produce finer droplet spectra and
increase drift potential.
Boom Length (Aircraft) and Application Height
x Boom Length (aircraft) - using shorter booms decreases drift potential. Boom lengths are expressed as a percentage
of an aircraft’s wingspan or a helicopter’s rotor blad e diameter. Shorter boom length and proper positioning can
minimize drift caused by wingtip or rotor vortices.
x Application Height (aircraft) - Applications made at the lowest height that are consistent with pest control
objectives and the safe operation of the airc raft will reduce the potential for spray drift.
x Application Height (ground) - Applications made at the lowest height cons istent with pest control objectives, and
that allow the applicator to keep the boom level with the a pplication site and minimize bounce, will reduce the
exposure of spray droplets to evaporation and wind, and reduce spray drift potential.
Wind
Apply when wind speeds are less than 15 mph. The wind speed range for optimum performance is between 3 and 10 mph. At
wind speeds less than 3 mph temperature inversions may exist, and at wind speeds above 10 mph spray patterns may be
compromised. However, many factors, including droplet size and equipment type determine drift potential at any given wind
speed. AVOID GUSTY OR WINDLESS CONDITIONS.
Note: Local terrain can influence wind patterns. Every applicator should be familiar with local wind patterns and how they
affect spray drift.
Temperature and humidity
Setting up equipment to produce larger droplets to compensate for droplet evaporation can reduce spray drift potential.
Droplet evaporation is most severe when conditions are both hot and dry.
Temperature inversions
Do not apply during surface temperature inversions. Drift potent ial is high during a surface temperature inversion. Surface
temperature inversions restrict vertical air mixing, which causes small suspended droplets to remain close to the ground and
move laterally in a concentrated cloud. Surface inversions are characterized by increasing temperature with altitude and are
common on nights with limited cloud cover and light to no wind. Th ey begin to form as the sun sets and often continue into
the morning. Mist or fog may indicate the presence of an inve rsion in humid areas. Inversions may also be identified by
producing smoke and observing its behavior. Smoke that remains cl ose to the ground, or moves laterally in a concentrated
cloud under low wind conditions indicates a surface inversion. Smoke that moves upward and rapidly dissipates indicates
good vertical air mixing.
Shielded Sprayers
Shielding the boom or individual nozzles can reduce the effects of wind. However, it is the res ponsibility of the applicator to
verify that the shields are minimizing drift potential and not interfering with uniform deposition of the product.
Sensitive Areas
Making applications when there is a sustained wind moving away from adjacent sensitive areas (e.g., residential areas, bodies
of water, known habitat for threatened or endangered species, non-target crops) is an effective way to minimize the effect of
spray drift.
DRIFT CONTROL ADDITIVES
Using product compatible drift control additives can reduce drift po tential. When a drift control additive is used, read and
carefully observe cautionary statements and a ll other information on the additive’s labe l. If using an additive that increases
viscosity, ensure that the nozzles and other application equipm ent will function properly with a viscous spray solution.
Preferred drift control additives have been certified by the Chemical producers and Distributors Association (CPDA).

Page 21 of 26
Upwind Swath Displacement
When applications are made with a crossw ind the swath will be displaced downwind. An adjustment for swath displacement
is made on the downwind edge of the application site by shifting the path of the application equipment upwind.
SPRAY DRIFT RESTRICTIONS
Where states have more stringent regulations they must be observed.
AERIAL APPLICATION
x When applying by air, use spray nozzles that will deliver co arse or larger spray droplets as defined in the American
Society of Agricultural and Biological Engineers (ASABE) standard ANSI/ASAE S572.1 (March 2009).
x The boom length must not exceed 75% of the wingspan or 80% of the rotor blade diameter.
x Applications with wind speeds greater than 15 miles per hour are prohibited.
x Applications into temperature inversions are prohibited.
x Spray must be released at the lowest height consistent with pest control objectives and flight safety.
x Applicators must consider the effects of nozzle orientation and flight speed when determining droplet size spectrum.
GROUND APPLICATIONS
x When applying by ground, use spray nozzles that will deliver medium coarse or larger spray droplets as defined in the
American Society of Agricultural and Biological Engineers (ASABE) standard ANSI/ASAE S572.1 (March 2009).
x Applications with wind speeds greater than 15 miles per hour are prohibited.
x Applications into temperature inversions are prohibited.
x Apply spray at the lowest height that is consistent with pest control objectives.
