USER SAFETY RECOMMENDATIONS
2
Follow manufacturer’s instructions for cleaning and maintaining PRE. If no such instructions for washables exist, use detergent 
and hot water. Keep and wash PRE separately from other laundry.
Users should:
• Remove clothing/PPE immediately if pesticide gets inside. Then wash thoroughly and put on clean clothing.
• Remove PRE immediately after handling this product. Wash the outside of gloves before removing. As soon as 
possible, wash thoroughly and change into clean clothing.
PERSONAL PROTECTIVE EQUIPMENT (PRE)
Applicators and other handlers must wear;
• Long sleeved shirt and long pants
• Shoes plus socks
• Chemical resistant gloves made of any waterproof material
ENVIRONMENTAL HAZARDS
For terrestrial use only. 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.
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 water table is shallow, may result in ground water 
contamination.
This product may contaminate water through drift of particles in wind. This product has a high potential for runoff for several 
months or more after application. Poorly draining soils and soils with shallow water tables are more prone to produce runoff 
that contains this product. 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 for contamination of water from rainfall/ 
runoff. Runoff of this product will be reduced by avoiding applications when rainfall is forecasted to occur within 48 hours. 
NON-TARGET ORGANISM ADVISORY STATEMENT; This product is toxic to plants and may adversely impact the forage 
and habitat of non-target organism, including pollinators, in areas adjacent to the treated area. Protect the forage and habitat 
of non-target organisms by following label directions intended to minimize drift.
WEED RESISTANCE MANAGEMENT
Some weeds are known to develop resistance to herbicides that have been used repeatedly. While the development of 
herbicide resistance is well understood, it is not easily predicted. Therefore, herbicides should be used in conjunction with the 
resistance management strategies in the area.
• For resistance management, please note that OPEN RANGE G contains a Group 2 herbicide. Any weed population 
may contain plants naturally resistant to Group 2 herbicides. The resistant individuals may dominate the weed 
population if these herbicides are used repeatedly in the same fields. Appropriate resistance-management strategies 
should be followed.
• To delay herbicide resistance, take one or more of the following steps;
• Rotate the use of OPEN RANGE G or other Group 2 herbicides within a growing season sequence or among growing 
seasons with different herbicide groups that control the same weeds in a field.
• Apply OPEN RANGE G at the correct timing and rate needed to control the most difficult weed in the field.
• 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 application method and timing to favor the crop and not the 
weeds); biological (weed-competitive crops or varieties) and other management practices.
• Scout fields prior to herbicide application to identify the weed species present and their growth stage to determine if 
the intended application will be effective.

3
Scout fields 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; and (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 when planting clean seed. 
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, and/or use non­
chemical means to remove escapes, as practical, with the goal of preventing further seed production.
Report any incidence of non-performance of this product against a particular weed species to your local 
Wilbur-Ellis Company LLC representative.
Contact your local sales representative, crop advisor, or extension agent to find out if suspected resistant weeds to this 
MOAhave 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.

PRODUCT INFORMATION
OPEN RANGE G is an herbicide applied as a dry granule to provide weed control and/or turf height suppression on pastures and 
rangeland (see “GUIDELINES FOR RANGELAND USE ” section). Federal Conservation Reserve Program (CRP) land that may be 
grazed or cut for hay, railroad utility, pipeline, and highway rights-of-way, railroad crossings, utility plant sites, petroleum tank 
farms, pumping installations, non-agricultural fence rows, storage areas, non-irrigation ditch banks, prairie sites, airports, industrial 
turf, golf courses, recreational and non-residential turf. OPEN RANGE G may be used for the release of bermudagrass, 
bahiagrass, smooth bromegrass, wheatgrass, “wildtype” common Kentucky bluegrass, native prairiegrass, wildflowers, crown 
vetch, other grasses and certain legumes. OPEN RANGE G can also be used for weed control during the establishment of native 
prairiegrasses and other grasses (see “REVEGETATION WITH PRAIRIEGRASSES AND OTHER GRASSES" section). 
OPEN RANGE G may also be used for conifer plantation site preparation.
OPEN RANGE G is readily absorbed through leaves, stems, and roots and is translocated rapidly throughout the plant, with 
accumulation in the meristematic regions. Treated plants stop growing soon after application. Chlorosis appears first in the 
newest leaves, and necrosis spreads from this point. In perennials, the herbicide is translocated into, and kills, underground 
storage organs which prevents regrowth. Chlorosis and tissue necrosis may not be apparent in some plant species for several 
weeks after application. Complete kill of plants may not occur for several weeks after application. Adequate soil moisture is 
important for optimum OPEN RANGE G activity. When adequate soil moisture is present, OPEN RANGE G will provide residual 
control of susceptible germinating weeds. Activity on established weeds will depend on the weed species and rooting depth. 
OPEN RANGE G will control annual and perennial grasses and broadleaf weeds and vine species. OPEN RANGE G will 
provide residual control of labeled weeds which germinate in the treated area. Certain brush species and ornamentals may be 
injured by direct application of OPEN RANGE G to their foliage.
OPEN RANGE G needs to be applied preemergence to the weeds.
OPEN RANGE G may be applied in the dormant or growing season for weed control.
Sensitivity of desirable grass species to OPEN RANGE G may be increased when grasses are stressed due to insect damage, 
disease, environmental conditions, shade, poorly drained soils or other causes.
Depending on the turf type being treated, some yellowing of turf may occur with applications during the growing season. 
Depending on weather conditions, yellowing will usually disappear in 2 to 4 weeks.
DO NOT apply OPEN RANGE G to newly seeded or sprigged grass stands, unless otherwise stated in this label (see 
“REVEGETATION WITH PRAIRIEGRASSES AND OTHER GRASSES ” section).

MANDATORY DRIFT MANAGEMENT
GROUND APPLICATIONS: Uniformly apply with properly calibrated ground equipment. Avoid overlaps when applying.

DRIFT ADVISORIES
THE APPLICATOR IS RESPONSIBLE FOR AVOIDING OFF-SITE SPRAY DRIFT
BE AWARE OF NEARBY NON-TARGET SITES AND ENVIRONMENTAL CONDITIONS
Managing Particle Drift from Aerial Applications: Applicators must follow these requirements to avoid off-target drift movement 
application heights - without compromising aircraft safety, applications must be made at a height of 20 feet above the crop 
canopy or tallest plants. Applicators must follow the most restrictive use cautions to avoid drift hazards, including those found 
in this labeling, as well as, applicable state and local regulations and ordinances.
AERIAL APPLICATION: Fixed wing aircraft and helicopters can be used to apply OPEN RANGE G, however, when making 
applications by fixed wing aircraft maintain appropriate buffer zones to prevent product drift out of the target area.
Only apply this product when the potential for drift to these and other adjacent sensitive areas (e.g., residential areas, bodies 
of water, known habitat for threatened or endangered species, or non-target crops) is minimal. DO NOT apply when the 
following conditions exist that increase the likelihood of drift from intended targets: high or gusty winds.
Avoiding drift at the application site is the responsibility of the applicator. The interaction of many equipment and weather- 
related factors determines the potential for drift. The applicator and the grower are responsible for considering all these factors 
when making decisions.
Drift from applying this product may result in damage to sensitive plants adjacent to the treatment area. To minimize drift, the 
applicator needs to be familiar with, and take into account, the following drift reduction advisory information. Additional 
information may be available from state enforcement agencies or the Cooperative Extension on the application of this product. 
Application Height: Making applications at the lowest possible height (aircraft, ground driven spray boom) that is safe, practical 
and efficacious.
APPLICATION INSTRUCTIONS
OPEN RANGE G may be applied with ground or aerial broadcast application equipment. Apply only with equipment capable of 
accurate calibration and uniform application of 20/40 mesh round sand.
DRIFT DIRECTIONS _________________________________________________________________________________
Aerial Applications:
• Do not release granules at a height greater than 20 feet above the vegetative canopy, unless a greater application height is 
necessary for pilot safety.
• Do not apply when wind speeds exceed 15 miles per hour at the application site.
Ground Applications:
• Apply with the boom or spinning disk at the discharge height recommended by the manufacturer but no more than 6 feet 
above the crop canopy.
• Do not apply when wind speeds exceed 15 miles per hour at the application site.
Swath Adjustment: When applications are made with a crosswind, the swath will be displaced downwind. Therefore, on the up 
and downwind edges of the field, the applicator must compensate for this displacement by adjusting the path of the application 
equipment (e.g., aircraft, ground) upwind. Swath adjustment distance should increase with increasing drift potential (higher 
wind, etc.).
Wind: Drift potential is lowest between wind speeds of 3-10 mph. However, many factors, including granule size and equipment 
type, determine drift potential at any given speed. NOTE: Local terrain can influence wind patterns. Every applicator needs to be 
familiar with local wind patterns and how they affect drift.
Wind Erosion: Avoid treating powdery dry or light sandy soils when conditions are favorable for wind erosion. Under these 
conditions, the soil surface should first be settled by rainfall or irrigation.
Aerial Application Methods and Equipment: Provide accurate and uniform distribution of granule over the treated area.

To ensure the protection of threatened and endangered plants when applying OPEN RANGE G to rangeland;
Federal agencies must follow NEPA regulations to ensure protection of threatened and endangered plants.
State agencies must work with the Fish and Wildlife Service or the Service’s designated state conservation agency to 
ensure protection of threatened and endangered plants.
Other organizations or individuals must operate under a Habitat Conservation Plan if threatened or endangered plants are 
known to be present on the land to be treated.
GUIDELINES FOR RANGELAND USE
OPEN RANGE G may be applied to rangeland for the control of undesirable vegetation to achieve one or more of the following 
vegetation management objectives;
The control of undesirable (non-native, invasive and noxious) plant species.
The control of undesirable vegetation to aid in the establishment of desirable rangeland plant species.
The control of undesirable vegetation to aid in the establishment of desirable rangeland vegetation following a fire. 
The control of undesirable vegetation for purposes of wildfire fuel reduction.
The release of existing desirable rangeland plant communities from the competitive pressure of undesirable plant species. 
The control of undesirable vegetation for purposes of wildlife habitat improvement.
FOR WEED CONTROL IN PASTURE AND RANGELAND
(For use only in the states of CO, ID, MT, NV, OR, UT, WA, and WY)
For the control of undesirable weeds in pasture and rangeland (see “GUIDELINES FOR RANGELAND USE ” section), apply 
OPEN RANGE G at 3.5 -21 lbs (0.031-0.186 lbs. a.i.) per acre as a broadcast treatment. See appropriate sections of this label 
for specific use directions.
OPEN RANGE G may only be applied to a given rangeland acre as specific weed problems arise. For the control of annual 
weed species such as cheatgrass, downy brome, and medusahead rye, a single application of OPEN RANGE G, that coincides 
with the successful establishment and/or release of desirable rangeland vegetation and the use of available IPM, can provide 
effective, sustainable control of the annual weed problem. For difficult to control perennial weed species such as leafy spurge, 
Dalmatian toadflax, and Russian knapweed, a single broadcast application of OPEN RANGE G is usually effective in most 
cases.
If needed, spot treatments with OPEN RANGE G can be used to control any remnant plants or new seedlings that may emerge. 
Long term control of undesirable weed species ultimately depends on the successful use of land management practices that 
promote the growth and sustainability of desirable rangeland plant species.
USE OF OPEN RANGE G HERBICIDE ON FEDERAL CONSERVATION RESERVE PROGRAM (CRP) LAND 
(For use only in the states of CO, ID, MT, NV, OR, UT, WA, and WY)
OPEN RANGE G may be used on Federal Conservation Reserve Program (CRP) land at rates up to 21 lbs (0.186 lbs. a.i.) 
per acre per year (See appropriate section of this label for specific instructions for the intended use).

Rotational Crops
7
Use of OPEN RANGE G in accordance with label directions is expected to result in normal growth of plant-back crops in most 
situations; however, various environmental and agronomic factors make it impossible to eliminate all risks associated with the 
use of the product and, therefore, plant-back crop injury is always possible. If crop injury is a concern, conduct a bioassay with 
the desired crop prior to planting.
’ After the specified rotational interval listed for these selected crops and for all crops not otherwise listed or included for use 
on this label, a successful field bioassay must be completed. The field bioassay consists of a test strip of the intended rotational 
crop planted across the previously treated field and grown to maturity. The test strip needs to include low areas and knolls and 
include variations in soil such as type and pH. If no crop injury is evident in the test strip, then the intended rotational crop may 
be planted the following year.

ROTATIONAL CROP RESTRICTIONS
The following rotational crops may be planted after applying OPEN RANGE G. Planting rotational crops earlier than the 
specified interval may result in crop injury.
RESTRICTIONS
• DO NOT apply more than 10.5 lbs. {0.093 lbs. a.i.) OPEN RANGE G per acre per application.
• DO NOT apply more than 10.5 ibs. (0.093 lbs. a.i.) OPEN RANGE G per acre per year.
• DO NOT apply more than 3 applications per acre per year at a rate of 3.5 Ibs. per acre.
• For repeat applications, allow a minimum 7-day interval between applications.
• DO NOT cut treated area for hay within 7 days after an application.
FOR FOLIAR AND SEEDHEAD SUPPRESSION OF BAHIAGRASS, COOL SEASON GRASSES AND SUPPRESSION OF 
SOME ANNUAL WEEDS
(Grazing and cutting for hay are only allowed in the states of CO, ID, MT, NV, OR, UT, WA, and WY)
BAHIAGRASS: OPEN RANGE G may be used at the rate of 3.5 to 10.5 lbs. (0.031-0.093 Ibs.a.i.) per acre to 
suppress growth and seedhead development of bahiagrass in unimproved areas. In North and South Carolina apply 
OPEN RANGE G at the rate of 3.5 Ibs. (0.031 Ibs. a.i.) or 5 Ibs. (0.044 Ibs. a.i.) per acre respectively, as higher rates may 
cause turf thinning. Depending on the rate specified for OPEN RANGE G used and environmental conditions, temporary turf 
discoloration may occur. For optimum performance, apply OPEN RANGE G after green-up. Applications may be made before 
or after mowing. If applied prior to mowing, raise mowing height to leave adequate existing foliage as new growth will be 
suppressed. If applied after mowing, allow adequate foliage to remain by increasing mower height or allowing time for foliar 
regrowth prior to application. DO NOT apply to turf under stress from drought, cold, insect, disease, or other causes, or severe 
injury may occur.

OPEN RANGE G may be used on bermudagrass turf on roadsides, utility rights-of-way, railroad crossings, airports, and 
non-irrigation drainage ditches. There is a differential sensitivity between bermudagrass types (see paragraphs below). 
Depending on bermudagrass type, timing of application, and OPEN RANGE G rate, some foliar, stolon, and seedhead 
suppression may occur. IMPORTANT: Apply OPEN RANGE G after bermudagrass has reached full green-up. Spring 
applications made prior to full green-up may delay green-up. DO NOT apply to grass under stress from drought, disease, 
insects, or other causes or severe injury may occur. Simultaneous mow/spray operations may suppress internode 
development. After mowing, allow adequate foliage regrowth prior to OPEN RANGE G application as some internode 
suppression may prevent bermudagrass from quickly recovering from mowing.
Common Bermudagrass: Common bermudagrass is the most resilient bermudagrass to OPEN RANGE G. Some 
stolon internode shortening and seedhead suppression may occur for the first 8 weeks.
Established Coastal Bermudagrass: OPEN RANGE G at 3.5 to 21 lbs. (0.031-0.186 lbs. a.i.) per acre will provide 
control of labeled weeds as well as foliar and seedhead suppression of established coastal bermudagrass. DO NOT use 
on World Feeder varieties of bermudagrass. Depending on environmental conditions and weed pressure, the longevity of 
suppression and weed control increases as the OPEN RANGE G rate increases.
Turf Type Bermudagrass: Turf type bermudagrass varieties show a high degree of variation in sensitivity to 
OPEN RANGE G. OPEN RANGE G at rates of 3.5 to 10.5 lbs. (0.031 -0.093 lbs. a.i.) per acre will provide some annual weed 
control and foliar and seedhead suppression. Rates above 10.5 lbs. (0.093 lbs. a.i.) per acre may result in excessive injury or 
death of turf type bermudagrass.
COOL SEASON GRASSES:
KY31 Tall Fescue and “Wildtype Common” Kentucky Bluegrass: Apply OPEN RANGE G at 3.5 to 7 lbs. (0.031-0.062 
lbs. a.i.) per acre for foliar and seedhead suppression of certain cool season grasses such as “KY31” tail fescue and 
“wildtype common” Kentucky bluegrass. Application to turf type tall fescue or Kentucky bluegrass may result in severe injury 
or loss of stand.

Bahiagrass Control: Apply OPEN RANGE G at the rate of 14 to 21 lbs. {0.124-0.186 lbs. a.i.) per acre postemergence. 
See “SPECIAL WEED CONTROL ” section below for directions.
Summer Annual Weeds: For best results, apply OPEN RANGE G at the rate of 7 to 21 lbs. (0.062-0.186 lbs. a.i.) per acre 
preemergence or early postemergence before weeds have reached 6 inches in height. Larger weeds may be controlled 
depending on susceptibility and, growing conditions.
Perennial Weeds: Apply OPEN RANGE G at the rate of 14 to 21 lbs. (0.124-0.186 lbs. a.i.) per acre postemergence after 
weeds have produced adequate foliage for herbicide uptake. For a particular weed see “SPECIAL WEED CONTROL ” section 
below.

FOR THE CONTROL OF UNDESIRABLE WEEDS IN UNIMPROVED CENTIPEDE GRASS
(Grazing and cutting for hay are only allowed in the states of CO, ID, MT, NV, OR, UT, WA, and WY)
OPEN RANGE G may be applied at a rate of 7 to 14 lbs. (0.062-0.124 lbs. a.i.) per acre to established centipede grass for 
the control of annual broadleaf and grass weeds. Apply OPEN RANGE G after centipede grass has reached full green-up. 
Spring applications made prior to full green-up may delay green-up. DO NOT apply to grass under stress from drought, disease, 
insects or other causes or severe injury may occur. Simultaneous mow/spray operations may suppress internode 
development. After mowing, allow adequate foliage regrowth prior to OPEN RANGE G application as some internode 
suppression may prevent centipede grass from quickly recovering from mowing.
FOR CONTROL OF UNDESIRABLE WEEDS IN SMOOTH BROMEGRASS, WILDTYPE COMMON KENTUCKY 
BLUEGRASS AND WHEATGRASSES
(Grazing and cutting for hay are only allowed in the states of CO, ID, MT, NV, OR, UT, WA, and WY)
OPEN RANGE G may be used on smooth bromegrass, “wildtype” common Kentucky bluegrass and wheatgrass. 
OPEN RANGE G provides control of labeled grass and broadleaf weeds (see “WEEDS CONTROLLED ” and “SPECIAL WEED 
CONTROL ” sections). Treatment of smooth bromegrass and wheatgrass with OPEN RANGE G may result in foliar height and 
seedhead suppression.
Smooth Bromegrass and “Wildtype” Common Kentucky Bluegrass: Use OPEN RANGE G at 7 to 14 lbs. (0.062-0.124 
lbs. a.i.) per acre in the spring for weed control and growth suppression after smooth bromegrass and “wildtype” common 
Kentucky bluegrass have reached 100% green-up. Applications prior to 100% green-up may delay green-up. Rates from 14 
to 21 lbs. (0.124-0.186 lbs. a.i.) per acre may be applied in the spring but may result in excessive growth suppression. For fall 
applications (see “SPECIAL WEED CONTROL ” section), OPEN RANGE G may be used at 14 to 21 lbs. (0.124-0.186 lbs. a.i.) 
per acre for control of perennial weeds.
Wheatgrass: To control undesirable weeds in wheatgrasses apply OPEN RANGE G at 7 to 21 lbs. (0.062-0.186 lbs. a.i.).

10
OPEN RANGE G rates of 14 to 21 lbs. (0.124-0.186 lbs. a.i.) per acre may result in stunting or stand thinning. The duration and 
intensity of suppression are directly related to weed pressure, chemical residue, soil type and environmental conditions. See 
below for details for specified grass sensitivity and timings.
Establishment: For optimum results in establishing mixed grass stands with OPEN RANGE G, make application at planting 
before grass seedlings emerge. Newly emerged grasses can be sensitive to OPEN RANGE G. If grasses have begun to emerge, 
it is best to wait until they have reached the five-leaf stage to make an OPEN RANGE G application. OPEN RANGE G will 
control annual weeds preemergence. See “WEEDS CONTROLLED ” section for maximum height of weeds and see below 
for more details on best rate and timing for grass and wildflower species. When planting into a field which was row cropped 
the previous year, compounded injury may occur from herbicide carryover (see “DIRECTIONS FOR USE ” section).
Rates and Control: Apply OPEN RANGE G at 3.5 to 10 lbs. (0.031-0.088 lbs. a.i.) per acre to fields cropped the previous 
year, when annual weeds are the target and/or if grass/forb mixtures are used. OPEN RANGE G at 3.5 to 10 lbs. (0.031- 
0.088 lbs. a.i.) per acre will provide control and/or suppression of many annual grass and broadleaf weeds. Use lower rates 
when in the northern most U.S., dry climates or for late season plantings into clean seedbeds. OPEN RANGE G rates as low 
as 3.5 lbs. (0.031 lbs. a.i.) per acre may be used on soils with a pH > 7, a low CEC and a coarse texture containing a minimum 
of clay and organic matter. Apply OPEN RANGE G at 14 to 21 lbs. (0.124-0.186 lbs. a.i.) per acre for giant ragweed or for 
perennial weed control/suppression.
REVEGETATION WITH PRAIRIEGRASSES AND OTHER FORAGE GRASSES
(Grazing and cutting for hay are only allowed in the states of CO, ID, MT, NV, OR, UT, WA, and WY)
OPEN RANGE G may be applied at the rate of 3.5 to 21 lbs. (0.031-0.186 lbs. a.i.) per acre to newly established or 
existing stands of labeled species (see below for details) in pasture and rangeland (see “GUIDELINES FOR RANGELAND 
USE ” section). Conservation Reserve Program (CRP) land and noncropland sites, roadsides, industrial sites, prairie 
restoration sites, drainage ditch banks. Certain local ecotypes or varieties may be suppressed by OPEN RANGE G. Many 
factors such as poor seedling vigor, cool temperatures, poor soil, planting depth, excessive moisture, disease, insects and 
dry weather after emergence can all result in poor stands. Additional stress of herbicide residue, poor soils and other factors 
contributing to poor seedling vigor can also increase injury and could result in mortality. To the extent consistent with applicable 
law, Wilbur-Ellis Company LLC cannot be held responsible for such unforeseen factors. It is advised to try OPEN RANGE G 
on a small area if sensitivity is not known. OPEN RANGE G controls many annual and perennial grass and broadleaf 
weeds. Weed competition is reduced allowing grass seedlings to establish. OPEN RANGE G is also effective for control of 
noxious weeds in established grass stands and must be applied postemergence as a foliar treatment to perennial weeds.
FOR CONTROL OF UNDESIRABLE WEEDS IN CROWN VETCH
(Grazing and cutting for hay are only allowed in the states of CO, ID, MT, NV, OR, UT, WA, and WY)
OPEN RANGE G may be applied at the rate of 7 lbs. (0.062 lbs. a.i.) per acre to newly seeded crown vetch beds to aid in 
the establishment of vetch and reduce weed competition.
OPEN RANGE G at 14 to 21 lbs. (0.124-0.186 lbs. a.i.) per acre may be used on unimproved established crown vetch in 
noncropland areas.
OPEN RANGE G provides control of labeled grass and broadleaf weeds (refer to the “WEEDS CONTROLLED ” and “SPECIAL 
WEED CONTROL ” sections for specific rates). Treatment of crown vetch beds with OPEN RANGE G may cause internode 
shortening and some minor tip chlorosis depending on timing of application.
OPEN RANGE G may be applied during winter dormancy or early spring to reduce potential injury. Applications, made after 
May, may result in increased injury or defoliation. Fall applications during the period of active crown vetch growth may result 
in severe injury or loss of stand.
RESTRICTIONS
• DO NOT apply more than 21 lbs. OPEN RANGE G (0.186 lbs. a.i) per acre per application.
• DO NOT apply more than 21 lbs. OPEN RANGE G (0.186 lbs. a.i.) per acre per year.
• DO NOT apply more than 3 applications per acre per year at a rate pf 7 lbs. per acre.
• For repeat applications, allow a minimum 7-day interval between applications.
• DO NOT cut treated area for hay within 7 days after an application.

11
Established Stands: For optimum results, apply OPEN RANGE G as a preemergent application to annual grasses and 
broadleaf weeds. For perennial weed control, see “SPECIAL WEED CONTROL ” section. The use of high rates may result 
in foliar and/or seedhead height suppression of established grass stands. This effect is more likely to occur under conditions of 
light soils, low weed pressure, low rainfall, and short growing seasons. Use the lower rates for light weed infestations or when 
applying to grass stands containing desirable wildflowers and legumes (see “WILDFLOWER ESTABLISHMENT AND 
MAINTENANCE ” section for rate sensitivity). Use higher rates to broaden and lengthen weed control spectrum.
Big Bluestem, Little Bluestem and Indiangrass: OPEN RANGE G may be applied at the rate of 3.5 to 21 lbs. (0.031- 
0.186 lbs. a.i.) per acre at planting, or any time thereafter, including after seedling grasses have emerged or to perennial 
stands (dormant or actively growing). See “WEEDS CONTROLLED ” section for specified rate. Use the lower rates in 
South Dakota and North Dakota and higher rates as rainfall and/or growing season increases.
Switchgrass (Panicum virgatum): OPEN RANGE G is not advised for the establishment of pure switchgrass stands as 
severe injury or death may result. OPEN RANGE G may be applied at a rate of 3.5 to 7 lbs. (0.031-0.062 lbs. a.i.) per acre if 
switchgrass is planted in mixed stands with non-sensitive species, but only if some stand thinning or loss of stand is acceptable. 
Mature switchgrass planting can be reclaimed from certain perennial weeds such as tall fescue, leafy spurge, johnsongrass, 
etc., with OPEN RANGE G at rates of 17.5 to 21 lbs. (0.155-0.186 lbs. a.i.) per acre. However, severe stunting and injury is 
imminent. DO NOT apply OPEN RANGE G to switchgrass if such severe injury is unacceptable.
Sideoats and Blue Grama: Apply OPEN RANGE G to monoculture stands of sideoats and blue grama only if some stand 
thinning or loss of stand is acceptable. OPEN RANGE G may be applied at the rate of 3.5 to 7 lbs. (0.031-0.062 lbs. a.i.) 
per acre to aid in the establishment of sideoats and blue grama after new seedlings have emerged and reached the five (5) 
leaf stage. The lower rates may provide adequate weed suppression in early summer plantings in the states of South Dakota, 
North Dakota, and other states where growing degree days are short. Sideoats and blue grama have shown resilience to 
OPEN RANGE G at 3.5 to 7 lbs. (0.031-0.062 lbs. a.i.) per acre, applied preemergence at planting, however, some stand 
thinning may occur. For weed control in established stands use 7 to 17.5 lbs. (0.062-0.155 lbs. a.i.) per acre of 
OPEN RANGE G. Up to 21 lbs. (0.186 lbs. a.i.) per acre of OPEN RANGE G may be applied but may result in foliar and/or 
seedhead suppression, or in the injury of sideoats and blue grama, depending on soil type, variety, weed pressure and 
environmental conditions.
Buffalograss: Apply OPEN RANGE G at the rate of 3.5 to 7 lbs. (0.031-0.062 lbs. a.i.) per acre for control or suppression of 
labeled weeds and to aid in the establishment of newly sprigged buffalograss. Apply OPEN RANGE G immediately after 
planting prior to spring growth or seed germination. New growth and small seedlings can be severely injured or killed. For 
established stands, OPEN RANGE G may be applied at the rate of 3.5 to 14 lbs. (0.031-0.124 lbs. a.i.) per acre for weed 
control. Higher specified rates may cause some turf discoloration and stunting. OPEN RANGE G may be applied to dormant 
buffalograss to control winter annual weeds. Turf type buffalograss may express different sensitivity levels to 
OPEN RANGE G than wild type buffalograss. Some turf types are resilient to low rates of OPEN RANGE G at seeding. 
Consult seed dealer for details.
Eastern Gamagrass: OPEN RANGE G can be used for the establishment or maintenance of eastern gamagrass if some 
stand thinning or loss is acceptable. Apply OPEN RANGE G at 3.5 to 10.5 lbs. (0.031-0.093 lbs. a.i.) per acre at planting prior to 
gamagrass emergence. Stand thinning and stunting is imminent. Adverse conditions, poor soils, or added stress to the 
gamagrass could result in stand mortality. Postemergent application to seedlings will cause mortality. On established eastern 
gamagrass, apply OPEN RANGE G at 3.5 to 14 lbs. (0.031-0.124 lbs. a.i.) per acre prior to gamagrass breaking dormancy. 
Some stunting will occur and increases as the OPEN RANGE G rate increases. Applications made during or after green-up 
may result in foliar and seedhead suppression and possible mortality of weak plants.
Tall Fescue Control: Tall fescue can be controlled by using OPEN RANGE G at the rate of 21 lbs. (0.186 lbs. a.i.) per 
acre in established stands of, or to prepare a seed bed for, big bluestem, little bluestem, and indiangrass. Tall fescue must be 
actively growing for optimum control. If tall fescue has reached the boot stage or has reached summer dormancy, control may 
be poor. Burning the fescue stand, where permitted, the following spring, just prior to green-up, will aid in control and provide a 
better seedbed for planting. Mowing the fescue several times the summer before fall application will weaken the fescue root 
system, making it more susceptible to herbicides. Always allow for at least 10 inches of regrowth, following the last mowing before 
spraying, as both OPEN RANGE G and glyphosate products need foliage present for herbicide uptake and satisfactory control.
RESTRICTIONS
• DO NOT apply more than 21 lbs. (0.186 lbs. a.i.) OPEN RANGE G per acre per application.
• DO NOT apply more than 21 lbs. (0.186 lbs. a.i.) OPEN RANGE G per acre per year.
• DO NOT apply more than 6 applications per acre per year at a rate of 3.5 lbs. per acre.
• For repeat applications, allow a minimum 7-day interval between applications.
• DO NOT cut treated area for hay within 7 days after an application.

For prairiegrass/wildflower mixtures: Where some wildflower injury {phytotoxicity, height suppression) is acceptable, apply 
OPEN RANGE G at a rate to achieve desired weed control, but not to exceed sensitivity rate listed in the table below. Wildflower 
injury can be reduced or eliminated with preemergent applications. To minimize injury, apply OPEN RANGE G at 3.5 to 7 lbs. (0.031- 
0.062 lbs. a.i.) per acre at planting to resilient species listed below. Use the 3.5 lbs. (0.031 lbs. a.i.) per acre rate under cool dry 
conditions and in low rainfall areas. If post-emergent applications are made to established prairiegrass/wildflower mixtures, use the 
lowest rate of OPEN RANGE G necessary to achieve desired weed control (see “WEEDS CONTROLLED ” section). Post-emergent 
applications can result in stand thinning or death due to vast variation in seed sources, varieties and genotypes. It is advised that a 
small area be tested prior to full application to determine the sensitivity of desired species. The rates listed below show those species 
in which an acceptable resilience to OPEN RANGE G has been confirmed on the varieties/genotypes being treated.

RESTRICTIONS
• DO NOT apply more than 7 lbs. (0.062 lbs. a.i.) OPEN RANGE G per acre per application.
• DO NOT apply more than 7 lbs. (0.062 lbs. a.i.) OPEN RANGE G per acre per year.
• DO NOT apply more than 2 applications per acre per year at a rate of 3.5 lbs. per acre.
• For repeat applications, allow a minimum 7-day interval between applications.
WILDFLOWER ESTABLISHMENT AND MAINTENANCE
Due to a high degree of variation in genotypes, ecotypes and varieties of wildflowers, sensitivity to OPEN RANGE G can vary 
dramatically and may be reduced under certain soil types and environmental conditions. Apply OPEN RANGE G only if some stand 
thinning or loss is acceptable. Preemergent applications of low use rates, 3.5 lbs. (0.031 lbs. a.i.) per acre to resilient species, result 
in the least amount of injury, but may not eliminate it. Preemergent applications of OPEN RANGE G can result in injury or death of 
some genotypes and needs to be used only as a rescue treatment when weed competition threatens the stand. Although most 
legumes listed in the Sensitivity Table are resilient to an application rate of 7 lbs. (0.062 lbs. a.i.) per acre of OPEN RANGE G when 
used preemergence, some stand thinning may occur. Legumes are more resilient to post emergent applications, but chlorosis or 
stunting is possible. Directions listed in the tables below are designed for mixed grass/wildflower stands. Less than satisfactory 
results may occur from applications to monoculture stands. Conduct a small-scale test to determine degree of satisfaction on 
monoculture stands.

Due to the diversity of species and varieties that exist in areas where wildflowers are grown, the response to 
OPEN RANGE G may vary greatly. To determine if area-wide applications can be made, conduct a small-scale test to determine 
sensitivity.
The suitability of OPEN RANGE G use on wildflower species that are not listed needs to be deteimined by treating a 
small number of such wild flowers at an appropriate rate, not to exceed 7 lbs. product (0.062 Lbs. a.i.) per acre per year. 
Treated wildflowers need to be evaluated 1 to 2 months following application for possible injury. TO THE EXTENT 
CONSISTENT WITH APPLICABLE LAW, THE USER ASSUMES RESPONSIBILITY FOR ANY DAMAGE OR OTHER 
LIABILITY.

RESTRICTIONS
• DO NOT apply more than 21 lbs. (0.186 lbs. a.i.) OPEN RANGE G per acre per application.
• DO NOT apply more than 21 lbs. (0.186 lbs. a.i.) OPEN RANGE G per acre per year.
• DO NOT apply more than 3 applications per acre per year at a rate of 7 lbs. per acre.
• For repeat applications, allow a minimum 7-day interval between applications.
RESTRICTIONS
• DO NOT apply more than 21 lbs. (0.186 lbs. a.i.) OPEN RANGE G per acre per application.
• DO NOT apply more than 21 lbs. (0.186 lbs. a.i.) OPEN RANGE G per acre per year.
• DO NOT apply more than 1 application per acre per year.
• For repeat applications, allow a minimum 7-day interval between applications.
• DO NOT use in forests. Only for use on sites that are managed as conifer plantations.
Leafy Spurge: For best results, apply OPEN RANGE Gat 14 to 21 lbs. (0.124-0.186 lbs. a.i.) per acre in late summer or fall (August 
through October, but timing may vary by state and/or altitude). Consecutive year applications will optimize long-term control. 
OPEN RANGE G at 21 lbs. (0.186 lbs. a.i.) per acre applied spring or fall, or 7 lbs. (0.062 lbs. a.i.) per acre in the spring 
following a 14 lbs. (0.124 lbs a.i.) per acre fall treatment may result in excessive injury to cool season grasses in some areas. 
Approximate dates for fall timing in North and South Dakota is late August through September. For Nebraska and Iowa, the timing is micF 
September through mid-October. This application needs to be made after good soil moisture is present but prior to the leafy 
spurge losing its milky sap flow due to a killing frost. To check and see if the milky sap flow has been affected by a frost simply 
break the main stem of the leafy spurge and if milky sap flows from the break then OPEN RANGE G can still be applied.
Tall Fescue Control: Tall fescue can be controlled by using OPEN RANGE G at the rate of 21 lbs. product (0.186 lbs. 
a.i.) per acre. Tall fescue must be actively growing for optimum control. If tall fescue has reached summer dormancy, control 
may be poor. Fall applications of OPEN RANGE G at 14 to 21 lbs. product (0.124-.186 lbs. a.i.) per acre will result in 
best control of existing tall fescue and new germinating seedlings. For spring applications of OPEN RANGE G at 10.5 to 21 
lbs. product (0.093-0.186 lbs. a.i.) per acre, use higher specified rates for older, mature fescue stands and lower 
OPEN RANGE G rates when planting forbs. When using 14 lbs. (0.124 lbs. a.i.) per acre of OPEN RANGE G in the fall, 
best results can be achieved by applying an additional 7 lbs. (0.062 lbs. a.i.) per acre OPEN RANGE G in the spring at 
planting for annual weed and seedling fescue control. Burning the fescue stand, where permitted, the following spring, just 
prior to green-up, will aid in control and provide a better seedbed for planting. Mowing the fescue several times the summer 
before fall application, will weaken the fescue root system, making it more susceptible to herbicides.
Russian Knapweed: Apply 21 lbs. (0.186 lbs. a.i.) per acre of OPEN RANGE G during Russian knapweed senescence 
in the fall. Control improves as senescence progresses and may still be obtained with applications made after full 
senescence. Applications made prior to the initiation of senescence will result in reduced control.
Dalmatian Toadflax: Apply 21 lbs. (0.186 lbs. a.i.) per acre of OPEN RANGE G plus in the fall when the top 25% of the 
plant is necrotic, usually after a hard frost (late October through November). The addition of ammonium sulfate at a rate of 2 
to 3 pints per acre may improve control. As long as there is some green stem and/or leaf tissue remaining, good control can 
be achieved. This timing usually corresponds to fall basal growth. Applications made prior to this will result in poor control.
Resistant Biotypes: Naturally occurring biotypes (a plant within a given species that has a slightly different, but distinct 
genetic makeup from other plants of the same species) of some weeds listed on this label may not be effectively controlled by 
this and/or other herbicides (sulfometuron methyl) with the ALS/AHAS enzyme inhibiting mode of action. If naturally occurring 
ALS/AHAS resistant biotypes are present in an area, OPEN RANGE G may be applied sequentially with an appropriate 
registered herbicide having a different mode of action to ensure control.
CONIFER PLANTATION SITE PREPARATION
OPEN RANGE G may be applied as a site preparation treatment prior to establishing conifer plantations to provide residual 
weed control of herbaceous weeds.

SENSITIVITY TREES AND BRUSH TO OPEN RANGE G: The following sensitivity information is provided as a general 
guideline when it is desirable or necessary to make OPEN RANGE G applications in and around desirable tree and brush 
species. DO NOT use OPEN RANGE G on nursery, orchard, ornamental plantings, new plantings, seedling trees or fiber 
farms. It is advised that OPEN RANGE G be tried on a limited basis to determine sensitivity in your area.
OPEN RANGE G may be used at rates up to 21 lbs. product (0.186 lbs. a.i.) per acre for weed control in and around established 
trees on roadsides and prairies used for wildlife cover, erosion control, wind breaks, etc. Tree and brush species known to have 
acceptable resilience to OPEN RANGE G when applied under the canopy and/or to the foliage are listed below. Resilience is 
based upon trees with a minimum of 2-inch DBH. Application to tree and brush species that are under stress due to drought, 
disease, insect damage or other factors may be more susceptible to injury from OPEN RANGE G and may result in severe injury 
or death. Some species may exhibit tip chlorosis and minor necrosis. Foliar contact may increase injury to include defoliation 
and terminal death. Application methods that minimize foliar contact with desirable tree and brush species can lessen 
sensitivity.
When making fall applications of OPEN RANGE G, potential injury to tree and brush species from foliar contact may be 
minimized by making the application after the leaves have begun to senesce (fall color) or after leaf drop. Conifer species are 
generally resilient to fall applications. For applications in and around tree and brush species apply OPEN RANGE G at the 
specified timing for the target weed species.
