WEED RESISTANCE-MANAGEMENT
For resistance management, ET Herbicide/Defoliant is a Group 14 herbicide. Any weed population may
contain or develop plants naturally resistant to ET Herbicide/Defoliant and other Group 14 herbicides. The
resistant biotypes may dominate the weed population if these herbicides are used repeatedly in the same
field. Appropriate resistance-management strategies should be followed.
To delay herbicide resistance, take one or more of the following steps:
x Rotate the use of ET Herbicide/Defoliant or other Group 14 herbicides within a growing season
sequence or among growing seasons with different herbicide groups that control the same weeds
in a field.
x Use tank mixtures with herbicides from a different group if such use is permitted; where
information on resistance in target weed species is available, use the less resistance-prone
partner at a rate that will control the target weed(s) equally as well as the more resistance-prone
partner. Consult your local extension service or certified crop advisor if you are unsure as to
which active ingredient is currently less prone to resistance.
x Adopt an integrated weed-management program for herbicide use that includes scouting and
uses historical information related to herbicide use and crop rotation, and that considers tillage (or
other mechanical control methods), cultural (e.g., higher crop seeding rates; precision fertilizer
{71711-7 ET Herbicide/Defoliant}
MAS-546-3 03312022-1

application method and timing to favor the crop and not the weeds), biological (weed-competitive
crops or varieties) and other management practices.
x Scout after herbicide application to monitor weed populations for early signs of resistance
development. 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. If resistance is
suspected, prevent weed seed production in the affected area by an alternative herbicide from a
different group or by a mechanical method such as hoeing or tillage. Prevent movement of
resistant weed seeds to other fields by cleaning harvesting and tillage equipment when moving
between fields, and planting clean seed.
x If a weed pest population continues to progress after treatment with this product, discontinue use
of this product, and switch to another management strategy or herbicide with a different mode of
action, if available.
x Contact your local extension specialist or cert ified crop advisors for additional pesticide
resistance-management and/or integrated weed-management recommendations for specific
crops and weed biotypes.
x For further information or to report suspec ted resistance, contact Nichino America, Inc.
representatives at 1-888-740-7700.
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.
Contact your local sales 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 mechanisms of actions for each target weed.
MANDATORY SPRAY DRIFT MANAGEMENT
[Aerial Applications:
x DO NOT release spray at a height greater than 10 ft above the vegetative canopy, unless a greater
application height is necessary for pilot safety.
x Applicators are required to use a fine or coarser dr oplet size according to the most recent version of
the American Society of Agricultural and Biological Engineers Standard 641 (ASABE S641).
x If the windspeed is 10 miles per hour or less, ap plicators must use ½ swath displacement upwind at
the downwind edge of the field. When the windspeed is between 11-15 miles per hour, applicators
must use ¾ swath displacement upwind at the downwind edge of the field.
x DO NOT apply when wind speeds exceed 15 mph at the application site. If the windspeed is greater
than 10 mph, the boom length must be 65% or less of the wingspan for fixed wing aircraft and 75%
or less of the rotor diameter for helicopters. Otherwise, the boom length must be 75% or less of the
wingspan for fixed-wing aircraft and 90% or less of the rotor diameter for helicopters.
x DO NOT apply during temperature inversions.]
Ground Boom Applications:
x User must only apply with the release height spec ified by the manufacturer, but no more than 4 feet
above the ground or crop canopy.
x Applicators are required to use fine or coarser dr oplet size according to the most recent version of
the American Society of Agricultural and Biological Engineers Standard 572 (ASAE S572).
x DO NOT apply when wind speeds exceed 15 miles per hour at the application site.
x DO NOT apply during temperature inversions.
{71711-7 ET Herbicide/Defoliant}
MAS-546-3 03312022-1
Page 7 of 35
Boomless Ground Applications:
x Applicators are required to use fine or coarser dr oplet size according to the most recent version of
the American Society of Agricultural and Biological Engineers Standard 572 (ASAE S572) for all
applications.
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.
x IMPORTANCE OF DROPLET SIZE - An effective way to reduce spray drift is to apply large droplets.
Use 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.
o Controlling Droplet Size - Ground Boom
ƒ 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.
ƒ Pressure - Use the lowest spray pressure directed for the nozzle to produce the
target spray volume and droplet size.
ƒ Spray Nozzle - Use a spray nozzle that is designed for the intended application.
Consider using nozzles designed to reduce drift.
o Controlling Droplet Size - Aircraft
ƒ Adjust Nozzles - Follow nozzle manufacturers specifications for setting up nozzles.
Generally, to reduce fine droplets, orient nozzles parallel with the airflow in flight.
x BOOM HEIGHT - Ground Boom
o For ground equipment, the boom must remain level with the crop and have minimal bounce.
x RELEASE HEIGHT - Aircraft
o Higher release heights increase the potential for spray drift.
x SHIELDED SPRAYERS
o 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.
x TEMPERATURE AND HUMIDITY
o When making applications in hot and dry condit ions, use larger droplets to reduce effects of
evaporation.
x TEMPERATURE INVERSIONS
o Drift potential is high during a temperat ure inversion. Temperature 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.
x WIND
o Drift potential increases with wind speed. AVOID APPLICATIONS DURING GUSTY WIND
CONDITIONS.
o Applicators need to be familiar with local wi nd patterns and terrain that could affect spray
drift.
{71711-7 ET Herbicide/Defoliant}
MAS-546-3 03312022-1
Page 8 of 35
x BOOMLESS GROUND APPLICATIONS
o Setting nozzles at the lowest effective height will help to reduce the potential for spray drift.
x HANDHELD TECHNOLOGY APPLICATIONS
o Take precautions to minimize spray drift.
TANK MIXTURES
It is the pesticide user's responsibility to ensure that all products are registered for the intended use. Read
and follow the applicable restrictions and limitations and application instructions on all product labels
involved in tank mixing. Users must follow the most restrictive application instructions and precautionary
statements of each product in the tank mixture.
ET Herbicide/Defoliant may be applied as a tank mix or in sequential application with other harvest aid,
herbicide, fungicide, or insecticide products. Weather, crop conditions, or the presence of certain weeds,
crop damaging insects, or diseases will indicate the inclusion of other pesticides in the defoliation or
desiccation application.
Note: Test compatibility of ET Herbicide/Defoliant in any tank mix combination before use. To determine
the physical compatibility with other products, use a jar test, as described below:
Using a quart jar, add the proportionate amounts of the products to 1 qt. of water. Add wettable powders
and water-dispersible granular products first, then liquid flowables, and emulsifiable concentrates last.
After thoroughly mixing, let stand for at least 5 minutes. If the combination remains mixed or can be
remixed readily, it is physically compatible. Once compatibility has been proven, use the same procedure
for adding required ingredients to the spray tank.
Read and follow all label directions for each tank mix product. Always use in accordance with the
most restrictive of label precautions and limitations.
MIXING DIRECTIONS
Keep agitation running during filling and spraying operations. If spraying must be stopped before
emptying the sprayer, resume agitation before spraying the remainder of the load. Mix only as much
spray solution as can be sprayed within four hours. Storage and use of the previous day’s spray mix may
result in reduced activity.
Use an approved agricultural buffering agent, buffering to pH 7.5 or less, if using ET Herbicide/Defoliant
in a water source greater than or equal to pH 7.5. Always buffer the water source BEFORE adding ET
Herbicide/Defoliant to the spray tank.
ET Herbicide/Defoliant Alone: Fill spray tank with ½ to ¾ of the amount of water needed for the
intended application and then turn on agitation. Pour the specified amount of product on the surface of
the water in the spray tank. Add the remaining water volume to the spray tank with agitation running.
Keep agitation running during filling and spraying operations.

ET Herbicide/Defoliant in Tank Mixtures: It is the pesticide user’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. Users must follow the most restrictive
directions for use and precautionary statements of each product in the tank mixture.
Begin with clean equipment. Fill spray tank with ½ to ¾ of the amount of water needed for the intended
application and turn on agitation. If using a buffering agent, add after filling the tank with ½ to ¾ amount of
water. Add the specified amount of tank mix products in the following order while maintaining agitation:
1) products in water-soluble packets
2) wettable powders
3) water-dispersible granulars and/or soluble powders
4) flowable liquids (including NNH-1792 SC Herbicide/Defoliant)
5) emulsifiable concentrates
6) adjuvants and/or oils
7) remaining amount of water to achieve the desired level
EQUIPMENT CLEANING
DO NOT allow the spray solution to dry in the application equipment. After application and before
using the sprayer equipment for any other applications, the sprayer must be thoroughly cleaned.
Applicators must ensure proper equipment clean-out for any other products mixed with ET
Herbicide/Defoliant as provided on the other product label(s). Immediately following application,
clean all equipment thoroughly with detergent or a spray tank cleaner and water as described below.
Should residues of ET Herbicide/Defoliant remain in inadequately cleaned equipment, they may be
released in subsequent applications and cause injury to crops.
1. Drain sprayer tank, hoses, and spray boom and th oroughly rinse with clean water the inside of the
spray tank, sprayer hoses, boom, and nozzles to remove any sediment or residues.
2. Fill the tank ½ full with clean water, add the ap propriate detergent (follow manufacturer’s directions
for use). Fill tank to capacity and operate the sprayer with agitation for 15 minutes to flush hoses,
boom, and nozzles.
3. Drain the sprayer tank, lines, and booms. Rins e the tank with clean water and flush through the
hoses, boom, and nozzles. Remove and clean spray nozzles, tips, and screens.
4. Dispose of all cleaning solutions, rinsate, an d washwaters in accordance with Federal, state, and
local regulations.

Turfgrass Use Precautions
Turfgrass species tolerant to ET Herbicide/Defoliant at labeled rates are listed below. For turfgrass
species not listed on this label, apply ET Herbicide/Defoliant to a small test area to assure tolerance. A
slight transitory yellowing or discoloration may occur on some sensitive turfgrass species under stress 3
to 5 days following application of ET Herbicide/Defoliant at labeled rates. Recovery is typically 4 to 7
days from application.
Cool Season Turfgrasses (bentgrass, Kentucky bluegrass, Rough bluegrass, tall fescue, perennial
ryegrass). Assure tolerance of both newly seeded and established cool season grasses by applying ET
Herbicide/Defoliant at labeled rates to a small test area before treating large areas. Be aware and
observe all label restrictions regarding turfgrass tolerance when ET Herbicide/Defoliant is tank mixed with
another product.
Warm Season Turfgrasses (common and hybrid bermudagrass, centipedegrass, St.
Augustinegrass, zoysiagrass). Assure tolerance to warm season turfgrasses listed above by applying
ET Herbicide/Defoliant at labeled rates to a small test area before treating large areas. Centipedegrass
may exhibit a slight yellowing 3 to 7 days after application, however complete recovery is expected. Be
aware and observe all label restrictions regarding turfgrass tolerance when ET Herbicide/Defoliant is tank
mixed with another product.
Newly Seeded, Sodded, or Sprigged Turfgrass
ET Herbicide/Defoliant may be applied to newly seeded, sodded, or sprigged turfgrass that is established
and not subject to impending stress due to moisture, temperature, or other cultural practices. Areas
treated with ET Herbicide/Defoliant may be seeded or overseeded one day following application.
Dormant Turfgrass
Applications of ET Herbicide/Defoliant to dormant warm season turfgrasses are permitted. DO NOT
apply when warm season turfgrasses are transitioning into or out of dormancy.
Apply ET Herbicide/Defoliant at rates specified in the dosage table below for control of broadleaf weeds.
ET Herbicide/Defoliant is a contact herbicide. ET Herbicide/Defoliant may be tank mixed with other
registered grass herbicides for control of grassy weeds. Avoid contact with desirable vegetation.

Example Calculation: Amount of Spray Concentrate to treat 5000 sq ft
Amount of Spray, fl. oz. = 2.8 fl oz x (128.2 fl oz Spray Concentrate) x 5000 sq. ft. x 1 acre
A 8.2 fl oz ET 43560 sq ft
= 2.8 x 15.6 x 5000
43560
= 5.0 fl oz spray concentrate to treat 5000 sq. ft.
where:
Application rate = 2.8 fl oz/A
Spray Concentrate Dilution: = 128.2 fl oz Spray Concentrate/ 8.2 fl oz ET
Area to Treat: = 5000 sq ft
Conversion Factor: = 1 acre/43560 sq ft

Spray Volume
ET Herbicide/Defoliant is a contact herbicide that causes herbicidal symptoms only to plant parts that
come into contact with spray applications. Therefore, proper spray volume and uniform coverage are
important to maximize efficacy of ET Herbicide/Defoliant. Apply uniform sprays at 20 to 200 gallons/A
(0.5 to 4.5 gallons per 1000 sq. ft). Use higher spray volumes to target high weed populations and/or
weeds contained in dense turfgrass canopies.
Use of Adjuvants
Addition of surfactants (spreaders/stickers) to the spray solution will improve efficacy and contact activity
of ET Herbicide/Defoliant. Follow manufacturers’ instructions on use rates for specific sites.

STORAGE AND DISPOSAL
DO NOT contaminate water, food, or feed by storage or disposal. Open dumping is prohibited.
Pesticide Storage: Store in a cool place.
Pesticide Disposal: Pesticide wastes are toxic. Improper disposal of excess pesticide,
pesticide spray or rinsate is a violation of Federal law. If these wastes cannot be disposed of by
use according to label instructions, contact your State Pesticide or Environmental Control
Agency, or the Hazardous Waste representative at the nearest EPA Regional Office for
guidance.
Container Handling: Nonrefillable container. DO NOT reuse or refill this container. Triple
rinse (or equivalent) promptly after emptying. Triple rinse as follows: Empty the remaining
contents into application equipment or a mix tank and drain for 10 seconds after the flow begins
to drip. Fill the container ¼ full with water and recap. Shake for 10 seconds. Pour rinsate into
application equipment or a mix tank or store rinsate for later use or disposal. Drain for 10
seconds after the flow begins to drip. Repeat this procedure two more times. Then offer for
recycling if available, or reconditioning if appropriate, or puncture and dispose of in a sanitary
landfill, or by incineration, or, if allowed by State or local authorities, by burning. If burned, stay
out of smoke.
