*** VAQUERO Herbicide is for use to control existing stands of field corn (including Roundup Ready
® corn) and
for use prior to replanting corn.

VAQUERO is a selective post-emergence herbicide for control of annual and perennial grasses.
VAQUERO does not control sedges or broadleaf weeds.
Control Symptoms: A reduction in vigor and growth is evident in treated grass weeds. Early chlorosis/necrosis of
younger plant tissue is followed by a progressive collapse of t he remaining foliage. Symptoms will generally be
observed in 7-14 days depending on grass species treated and environmental conditions.
In some grass species, repeated use of VAQUERO (or similar post -emergence grass herbicides with the same
mode of action) may lead to the selection of naturally occurrin g biotypes that are resistant to these products. A
resistant biotype may be present if poor performance occurs and cannot be attributed to adverse weather or
application conditions. This potential resistance will most lik ely occur in fields where other control strategies
such as crop rotation, mechanical removal, and other classes of herbicides are not used from year-to-year.
Do not allow VAQUERO to contact desirable grass crops such as c orn, rice, sorghum, small grains, or turf, as
these and other grass crops will be injured or killed. Minor le af spotting may occur on treated plants under
certain environmental conditions. New foliage is not affected.
VAQUERO is not for use on vegetable crops being grown for seed production unless specific use directions are
provided in this label or through Supplemental Labeling.
Not all specialty varieties of vegetable crops on this label ha ve been tested for tolerance to VAQUERO. It is
advised that, before applying VAQUERO to specialty varieties of crops listed on this label, crop tolerance should
be investigated first using a small section of the field. It is possible that injury symptoms may occur. Symptoms
may appear as leaf speckling or stunting.
Best perennial grass control can be obtained if rhizomes or sto lons are cut up by preplant tillage practices,
(discing, plowing, etc.) to stimulate maximum emergence of grass shoots. Cultural practices, such as continuous
no-tillage in which the perennial grass rhizomes or stolons are not cut up, result in a very staggered, non-
uniform weed emergence. Under these conditions and due to such non-uniform weed emergence, make no
fewer than two VAQUERO applications per year at the appropriate weed-growth stage rate under continuous
no-till conditions.

APPLICATION INFORMATION
Application Timing
Apply VAQUERO post-emergence to actively growing grasses accord ing to rate table directions in this label.
Do not apply to grass plants under stress from insufficient moi sture or cold temperatures, or to grass plants
exceeding recommended growth stages as unsatisfactory control may result.
In arid regions where irrigation is used to supplement limited rainfall, VAQUERO should be applied as soon as
possible after an irrigation (within 7 days). In arid regions, a second application of VAQUERO will generally
provide more effective control of perennial grass weeds than a single application. Make second application to
actively growing grass 2 - 3 weeks after emergence of new growth.
Cultivation of treated grasses 7 days prior to or within 7 days after application of VAQUERO may reduce weed
control. DO NOT APPLY VAQUERO if rainfall is expected within 1 hour of application since control may be
reduced.
Ground Application
To ensure complete coverage, it is essential to use sufficient spray volumes and pressure. Use a minimum of 5
gallons and a maximum of 40 gallons of spray solution per acre. Under the following conditions, a minimum of
10 gallons per acre is required: na rrow row soybeans, broadleaf herbicide tank mixes, perennial grasses,
volunteer corn, drought or stress conditions, heavy grass press ure or when grasses are at, or near, maximum
height. Failure to use a minimum of 10 gallons per acre under t hese conditions can result in poor coverage and
reduced grass control requiring repeat applications. Spray pres sures should reflect a minimum of 30 psi and a
maximum of 60 psi at the nozzle. Do not use flood nozzles.
Applications to onions (dry bulbs and green), garlic, and shall ots (dry bulbs and green) should be made in a
minimum of 20 gallons of spray solution per acre.

Aerial Application
AERIAL APPLICATION IS PROHIBITED FOR ALL TREE FRUITS AND TREE NUTS.
Use a minimum of 3 gallons of sp ray solution per acre unless ot herwise directed on this label. As grass or crop
foliage becomes dense, increase spray volume up to 10 gallons.

For onions (dry bulbs and green), garlic, or shallots (dry bulb s and green): Do not exceed 8 fl. oz./A (0.125 lb.
a.i./A) in a single application when applying by air. In Califo rnia, air applications to onions, garlic or shallots
should be made in a minimum of 20 gallons of spray solution per acre. NOTE: Crop injury may occur when
VAQUERO is applied to onions, garlic, or shallots with aerial equipment.
Spot Treatment
When using hand sprayers or high-volume sprayers utilizing hand guns, mix 1/4
% - 1/2% (0.33 oz. - 0.65 oz. per
gallon) VAQUERO and spray to wet vegetation, while not allowing runoff of spray solution. For uses where a
crop oil concentrate (COC) or methylated seed oil (MSO) are rec ommended, include the COC or MSO at 1 %
(1.3 oz. per gallon) by volume. For uses where a non-ionic surf actant is recommended, include the non-ionic
surfactant at 1/4% (0.33 oz. per gallon) by volume.
NOTE: If VAQUERO is applied as a spot treatment, do not exceed the maximum rate allowed on a “per acre”
basis or crop injury may occur.

USE RESTRICTIONS
x Do not apply if rain is expected within 1 hour of application as unsatisfactory control may occur.
x Do not plant rotational crops until 30 days after application of VAQUERO unless crop is listed on
VAQUERO label.
x Aerial application for all tree fruits and tree nuts is prohib ited.
x Refer to crop specific Directions For Use for restrictions on:
o Number of annual applications allowed per year
o Maximum amount of product that may be applied per year per acr e
o Maximum single application rates
o Minimum spray intervals between applications

6

x Do not apply a post-emergence broadleaf herbicide within one d ay following application of VAQUERO or
reduced grass control may result.
x Do not apply under conditions of stress. Applying VAQUERO unde r conditions that do not promote active
grass growth will reduce herbicide effectiveness. These conditi ons include drought, excessive water,
extremes in temperature, low humidity and grasses either partially controlled or stunted from prior pesticide
applications. Grasses under these kinds of stressful conditions will not absorb and translocate VAQUERO
effectively, and will be less susceptible to herbicide activity.
x Do not allow VAQUERO to contact desirable grass crops such as corn, rice, sorghum, small grains, or turf,
as these and other grass crops will be injured or killed. Minor leaf spotting may occur on treated plants
under certain environmental conditions. New foliage is not affected.
x Application in Nassau and Suffolk counties of New York State is restricted to no more than 16 fl. oz. of
VAQUERO (0.25 lb. a.i.) per acre per year.

CHEMIGATION INFORMATION
This product may be applied to onions and garlic by sprinkler i rrigation systems. DO NOT apply by chemigation
to any other crop.

CHEMIGATION – ONIONS (Dry Bulbs and Green) AND GARLIC ONLY
SPRINKLER IRRIGATION APPLICATION
x Do not apply VAQUERO by chemigat ion in the states of Idaho, Montana, Oregon and Washington.
x Do not apply VAQUERO by chemigation to any other crop besides onions and garlic.
Apply VAQUERO at the high rate specified for annual grasses (16 fl. oz./A) when the grass height is at the
shorter end of the height range (application to taller grasses may not provide adequate control). Add a non-ionic
surfactant at 0.25% v/v.
Apply VAQUERO in 0.1 - 0.2 acre-inch of water either at the end of a regular irrigation set or as a separate
application not associated with a regular irrigation using the least amount of water that provides proper
distribution and coverage. Application of more than label specified volume of irrigation water per acre may result
in decreased product performance by removing the chemical from the zone of effectiveness. Use a metering
device to inject VAQUERO into irrigation water at a constant flow.
Constant agitation must be maintained in the chemical supply ta nk during the entire period of herbicide
application. Inject the product with a positive displacement pump into the main line ahead of a right angle turn to
ensure adequate mixing. Allow time for all lines to flush the h erbicide through all nozzles before turning off
irrigation water. To ensure the lines are flushed and free of r emaining herbicide, a dye indicator may be injected
into the lines to mark the end of the application period.
Do not apply VAQUERO through an irrigation system connected to a public water system. A public water
system is a system for the provision of piped water to the publ ic for human consumption when such system has
at least 15 service connections or regularly serves an average of at least 25 individuals daily at least 60 days
out of the year.

USE PRECAUTIONS
1. Apply this product only through the following sprinkler irri gation systems: center pivot, lateral move, end tow,
side (wheel) roll, travelers, big gun, solid set, or hand move. Do not apply this product through any other
type of irrigation system.
2. Crop injury, lack of effectiveness, or illegal pesticide res idues in the crop may result from non-uniform
distribution of treated water.
3. If you have any questions about calibration, you should cont act State Extension Service specialists,
equipment manufacturers or other experts.
4. Do not connect an irrigation system (including greenhouse sy stems) used for pesticide application to a
public water system unless the label-prescribed safety devices for public water supplies are in place.
5. A person knowledgeable of the chemigation system and respons ible for its operation or under supervision of
the responsible person, shall shut the system down and make necessary adjustments should the need arise.

7

6. The system must contain a func tional check valve, vacuum relief valve, and low pressure drain appropriately
located on the irrigation pipeline to prevent water source contamination from backflow.
7. The pesticide injection pipeline must contain a functional, automatic, quick-closing check valve to prevent
the flow of fluid back toward the injection pump.
8. The pesticide injection pipeline must also contain a functio nal, normally closed solenoid-operated valve
located on the intake side of the injection pump and connected to the system interlock to prevent fluid from
being withdrawn from the supply tank when the irrigation system is either automatically or manually shut
down.
9. The system must contain functional interlocking controls to automatically shut off the pesticide injection
pump when the water pump motor stops.
10. The irrigation line or water pump must include a functional pressure switch which will stop the water pump
motor when the water pressure decreases to the point where pesticide distribution is adversely affected.
11. Systems must use a metering pump, such as a positive displa cement injection pump (e.g., diaphragm
pump) effectively designed and co nstructed of materials that ar e compatible with pesticides and capable of
being fitted with a system interlock.
12. Do not apply when wind speed favors drift beyond the area intended for treatment.

SPRAY DRIFT
SPRAY DRIFT DIRECTIONS

Aerial Applications:
x Do not release spray at a height greater than 10 feet above the vegetative canopy, unless a greater
application height is necessary for pilot safety.
x Applicators are required to use a coarse or coarser droplet size (ASABE S572.1).
x The boom length must not exceed 65% of the wingspan for airplanes or 75% of the rotor blade diameter
for helicopters.
x Applicators must use ½ swath displacement upwind at the downwi nd edge of the field.
x Nozzles must be oriented so the spray is directed toward the back of the aircraft.
x Do not apply when wind speeds e xceed 10 miles per hour at the application site.
x Do not apply during temperature inversions.
Ground Boom Applications:
x Apply with the nozzle height recommended by the manufacturer, b ut no more than 3 feet above the
ground or crop canopy. For all other ground applications, the n ozzle must be no more than 3 feet from
the target vegetation.
x Applicators are required to use a medium or coarser droplet size (ASABES572.1).
x Do not apply when wind speeds e xceed 10 miles per hour at the application site.
x Do not apply during temperature inversions.

SPRAY DRIFT ADVISORIES
THE APPLICATOR IS RESPONSIBLE FOR AVOIDING OFF-SITE SPRAY DRIFT.
BE AWARE OF NEARBY NON-TARGET SITES AND ENVIRONMENTAL CONDITIONS
IMPORTANCE OF DROPLET SIZE
An effective way to reduce spray drift is to apply large drople ts. 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.

8

Controlling Droplet Size – Ground Boom
x Volume – Increasing the spray volume so that larger droplets are produc ed will reduce spray drift. Use
the highest practical spray volume for the application. If a g reater spray volume is needed, consider
using a nozzle with a higher flow rate.
x Pressure – Use the lowest spray pressure recommended for the nozzle to pr oduce the target spray
volume and droplet size.
x Spray Nozzle – Use a spray nozzle that is designed for the intended applicati on. Consider using
nozzles designed to reduce drift.
Controlling Droplet Size – Aircraft
x Adjust Nozzles – Follow nozzle manufacturers recommendations for setting up noz zles. Generally, to
reduce fine droplets, nozzles should be oriented parallel with the airflow in flight.
BOOM HEIGHT – Ground Boom
For ground equipment, the boom should remain level with the crop and have minimal bounce.
RELEASE HEIGHT – Aircraft
Higher release heights increase the potential for spray drift.
SHIELDED SPRAYERS
Shielding the boom or individual nozzles can reduce spray drift . Consider using shielded sprayers. Verify that
the shields are not interfering with the uniform deposition of the spray on the target area.
TEMPERATURE AND HUMIDITY
When making applications in hot and dry conditions, use larger droplets to reduce effects of evaporation.
TEMPERATURE INVERSIONS
Drift potential is high during a temperature inversion. Tempera ture 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 con centrated cloud, (under low wind conditions)
indicates an inversion, while smoke that moves upward and rapid ly dissipates indicates good vertical air mixing.
Avoid applications during temperature inversions.
WIND
Drift potential generally increases with wind speed. AVOID APPL ICATIONS DURING GUSTY WIND
CONDITIONS.
Applicators need to be familiar with local wind patterns and terrain that could affect spray drift.


TANK MIXES (See page 41 for additional tank mix instructions)
Always read and follow the entire label of each product to be used in the tank mix with this product.
Always follow the most restrictive label language, including al l crop rotation and other crop restrictions, for all
products whether used alone, or in a tank mix.
Tank mixes of VAQUERO and broadleaf herbicides may result in re duced grass control. If grass regrowth
occurs, an additional application of VAQUERO may be necessary.
Tank mixing or use of this product with any other product which is not specifically and expressly authorized by
the label shall be the exclusive risk of the user, applicator and/or applicator advisor.


WEED RESISTANCE MANAGEMENT
Some weeds are known to develop resistance to herbicides that h ave been used repeatedly. While the
development of herbicide resistance is well understood, it is n ot easily predicted. Therefore, herbicides should
be used in conjunction with the resistance management strategies in the area.

9

For resistance management, please note that VAQUERO contains a Group 1 herbicide. Any weed population
may contain plants naturally resistant to Group 1 herbicides. T he 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 VAQUERO or other Group 1 herbicides within a growing season sequence or among
growing seasons with different herbicide groups that control the same weeds in a field.
x Apply VAQUERO at the correct timing and rate needed to control the most difficult weed in the field.
x Use tank mixtures with herbicides from a different group if su ch use is permitted; where information on
resistance in target weed species is available, use the less re sistance-prone partner at a rate that will
control the target weed(s) equally as well as the more resistan ce-prone partner. Consult your local
extension service or certified crop advisor if you are unsure a s 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 application
method and timing to favor the crop and not the weeds), biological (weed-competitive crops or varieties)
and other management practices.
x Scout fields prior to herbici de application to identify the weed species present and their growth stage to
determine if the intended application will be effective.
x Scout fields after herbicide application to monitor weed popul ations for early signs of resistance
development. Indicators of possible herbicide resistance includ e: (1) failure to control a weed species
normally controlled by the herbicide at the dose applied, espec ially if control is achieved on adjacent
weeds; (2) a spreading patch of non-controlled plants of a part icular weed species; and (3) surviving
plants mixed with controlled individuals of the same species. I f resistance is suspected, prevent weed
seed production in the affected area by an alternative herbicid e 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 treatmen t with this product, discontinue use of this
product, and switch to another m anagement 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 representative or call (720) 306-6340.

ADJUVANT RECOMMENDATIONS
The addition of a crop oil concentrate or methylated seed oil o r a non-ionic surfactant such as RAINIER-EA ® or
R-11® will improve the performance of VAQUERO. Crop oil concentrates and methylated seed oils can cause
crop injury with certain tank mix partners or on sensitive crop s. Under these circumstances, non-ionic
surfactants (NIS) can be used in place of crop oil concentrates . Reduced weed control may result from use of
non-ionic surfactant, instead of crop oil concentrates. Oil/nit rogen blend adjuvants may be substituted for crop
oil concentrates or methylated seed oil at appropriate equivale nt use rates. Under drought conditions,
methylated seed oil adjuvants can be used in place of COCs to i mprove performance. Methylated seed oils can
increase crop injury potential and care should be taken when considering their use. Ammonium sulfate (AMS) or
urea-ammonium nitrate (UAN), and similar liquid foliar nitrogen fertilizers can improve control of hard to control
grasses and help overcome potential antagonism from tank mix pa rtners. The use of AMS or UAN is only
allowed on specified crops and may increase the possibility of crop injury under some conditions.

RESTRICTIONS:
•Do not apply more than 16 fl. oz./A in a single application.
•Do not make more than 4 applications per year.
•Do not apply more than 64 fl. oz./A (1.0 lb. a.i./A) per year.
•For repeat applications, allow a minimum 14-day interval between applications.

Mowing: The best control of annual grasses can be achieved by applying VAQUERO before grass weeds are
mowed. Once a grass is mowed it becomes tougher to control, as much of the available leaf surface has been
removed. In areas without a killing frost, some annuals can over-winter after having been mowed multiple times.
These grasses form large crowns and may contain many viable buds. These grasses, even though they may be
an annual grass, may require repeated application of VAQUERO for partial or complete control.
Irrigated Alfalfa and Mint: In established alfalfa and mint, irrigation practices can be v ery critical to the
successful use of VAQUERO and may be necessary to initiate acti ve growth of the weeds prior to application.
Generally, applications 2-4 days following irrigation are most effective. More consistent grass control occurs
when the irrigation occurs before the application is made but i rrigation shortly after application (2 days) can be
effective.
Aerial Application: Apply VAQUERO in a minimum of 10 GPA in established alfalfa a nd mint when applying
by air.
Annual Grass Control: Apply VAQUERO at the grass sizes indicated in the Use Directio ns for Annual Grass
Table and rates indicated above (10-16 fl. oz./A). If a grass h as been cut, apply VAQUERO after active growth
has resumed and regrowth has reached the minimum height and bef ore it reaches the maximum height
indicated. Apply before the alfalfa/mint canopy covers the gras ses and interferes with the spray coverage.
Some annual grasses are spring a nd summer germinating plants, w hile others are fall germinating plants, and
the time they are actively growing and most susceptible to VAQU ERO may vary from region to region. Also,
some annuals germinate over an extended period of time, and bec ause control of small grasses is desired,
applications after each weed flush may be required. As a genera l rule, spray spring and summer germinating
grasses as early in the season as possible, after initial green -up. Spray fall germinating weeds in the fall soon
after they begin growing but before any damage is done due to f rost. Late fall applications may be less effective
due to environmental conditions, such as frost, slower plant growth, or the onset of flowering.

39

Perennial Grass Control: VAQUERO effectively controls p erennial grasses such as bermuda grass,
Johnsongrass, quackgrass, wires tem muhly, tall fescue, foxtail barley and orchardgrass. Due in part to lack of
tillage, perennial grasses are more difficult to control in a p erennial crop such as established alfalfa or mint. A
program of repeated applications is usually necessary for best results. The best way to control perennial
grasses is to do so in the year of stand establishment before r hizomes and stolons become large and difficult to
kill.
Use the high rate when grasses are at or near maximum height and/or under heavy grass pressure.
Always add a crop oil concentrate at 1 qt./A by ground or 1% v/ v (but not less than 1 pt./A) to the finished spray
volume by air.

TANK MIXES
The labels for pesticides which may be tank mixed with VAQUERO are unique to the characteristics of those
products and contain restrictions and limitations that may be more restrictive than the VAQUERO label in certain
considerations. These may include, but are not limited to:
1. Geographic restrictions – not all products are registered for use in all areas and rates may vary from one
region of labeled use to another
2. Crop rotation restrictions
3. Applicator certification requirements
4. Worker safety rules (i.e., protective clothing requirements, reentry time)
5. Soil type or soil characteristics
6. Maximum application rate or number of applications allowed p er year
7. Rain-free period required
8. Application timing (E.G., PRE-HARVEST INTERVAL)
9. Do not exceed the total yearly rates.

THE MOST RESTRICTIVE LABELING OF ANY PRODUCT USED IN A TANK MIX MUST BE FOLLOWED.

TANK MIX APPLICATION OF VAQUERO AND BROADLEAF HERBICIDES FOR CONTROL OF GRASSES
AND BROADLEAF WEEDS
x Apply only to actively growing grass and broadleaf weeds at re commended height or growth stage listed on
each label.
x Apply when the first grass or b roadleaf weed species in a mixe d population reaches the recommended
height or growth stage for treatment.
x Apply under favorable soil moisture and humidity, which exist a few days after rainfall or within seven days
after irrigation.
x Always add the appropriate adjuvant to the spray mix at the ra te recommended for each specific tank mix
combination.
x Tank mix applications may sometimes result in reduced grass co ntrol and possible increases in crop injury
as compared to either product used alone. If regrowth occurs, o r an additional flush of new grass emerges,
make a second application of VAQUERO as specified in the respective size and rate tables.
x Do not tank mix VAQUERO when broadleaf weeds are tall and/or d ense enough to prevent proper grass
coverage.

MIXING INSTRUCTIONS

Use the jar test to verify mixing and compatibility properties. Maintain agitation throughout the spray application.
Unsatisfactory weed control may result due to improper mixing i f continuous agitation is not maintained during
application.

VAQUERO MIXING INSTRUCTIONS:
1. Fill clean spray tank 1/2-2/3 of desired level with clean water
2. While agitating, add the specified amount of VAQUERO post-em ergence grass herbicide. Agitation
should be vigorous enough to be visible on the surface of the water.
3. If tank mixing VAQUERO with other labeled herbicides, add wa ter soluble packets first, followed by dry
formulations, flowables, emulsifiable concentrates and then sol utions. Prepare no more spray mixture
than is required for the immediate spray operation.
4. Add any required adjuvants (NIS, COC/MSO, and/or nitrogen or AMS solution).
5. Add any drift reduction products, such as IN-PLACE
® or CROSSHAIR®.
6. Finish filling spray tank to the desired level with water. A gitation should continue until the spray solution
has been applied in its entirety.

41

INFORMATION ON ANTAGONISM
Tank mixes of VAQUERO with post-emergence broadleaf herbicides have shown some reduction or failure to
control certain grass species which would have otherwise been c ontrolled when VAQUERO is applied alone.
Activity of the post-emergence broadleaf herbicide in the tank mix is not affected.

 DIRECTIONS FOR MICRO-RATE APPLICATIONS TO SUGARBEETS
Multiple micro-rate applications of VAQUERO in tank mixtures wi ll reduce rates of Betanex ® or Betamix ® and
methylated seed oils may be applied by air or ground equipment to sugarbeets to control early germinating
annual grasses listed above. The rate of Betanex or Betamix mus t not exceed 0.12 lb. ai/A (broadcast
application) when in combination with these spray adjuvants. No te that maximum rate allowed varies depending
on crop growth stage. The use of wetting agents or spray adjuva nts with conventional rates (0.73-1.22 lb. ai/A)
or multiple low rate (0.24-0.73 lb. ai/A) applications of Betan ex or Betamix is prohibited on the Betanex or
Betamix master label. Favorable climatic conditions (good condi tions for plant growth and development) are
essential for adequate weed control. All use precautions and re strictions on the Betanex or Betamix master
labels must be followed.
DIRECTIONS FOR MICRO-RATE MULTIPLE APPLICATIONS OF VAQUERO TANK M I X E S T O
SUGARBEETS
Apply VAQUERO in broadcast applications only at a rate of 2-3 f l. oz./A in tank mixtures with either Betanex or
Betamix following the directions for use on the tank mix partne r label. A minimum of 3 sequential applications of
2 fl. oz./A or a minimum of 2 sequential applications of 3 fl. oz./A should be utilized for VAQUERO tank mixtures.
A minimum of 3 sequential applications of Betanex or Betamix sh ould be used. Accurate timing is essential;
make initial application immediately after weeds emerge, and ma ke repeat applications on 5 - 7day intervals. If
weed control is not adequate due to climatic conditions, spray coverage or other factors, return to conventional
application rates of VAQUERO (6 - 8 fl. oz./A) and add rates of Betanex or Betamix in tank mixtures with
VAQUERO. A spray adjuvant is not recommended.

USE PRECAUTIONS FOR MICRO-RATE APPLICATIONS: (SEE VAQUERO, BETA NEX AND BETAMIX
MASTER LABEL FOR FURTHER USE PRECAUTIONS)
Not all weeds will be adequately controlled, even with favorabl e climatic conditions. Conventional rate of
VAQUERO, Betanex or Betamix and/or hand labor may be required i f multiple micro-rate applications do not
adequately control weeds. Plugging of spray nozzles may be enco untered due to the potential for formation of a
precipitate in the spray solution that is often associated with micro-rate applications. Wilbur-Ellis Co. will not be
responsible for any nozzle plugging that may occur with the use of multiple micro-rate applications. Methylated
seed oils must not be added if the Betanex or Betamix rate exce eds 0.12 lb. ai/A broadcast, as the addition of
methylated seed oils could increase the possibility of crop injury at dosage rates greater than 0.12 lb. ai/A.
GROUND APPLICATION
Use of sufficient spray volumes and pressure is essential to en sure complete coverage. Use a minimum of 10
gallons and a maximum of 20 gallons of spray solution per acre. Spray pressures should reflect a minimum of
30 psi and a maximum of 60 psi at the nozzle. Do not use flood nozzles.
AERIAL APPLICATION
Use of sufficient spray volumes is essential to ensure complete coverage. Use a minimum of 5 gallons and a
maximum of 15 gallons of spray solution per acre.


DIRECTIONS FOR USE IN FALLOW LAND
VAQUERO may be used to control annual and perennial grasses in land that has been left fallow the previous
year and other non-producing agricultural areas. Apply VAQUERO at 6 - 8 fl. oz./A for annual grasses and
8 - 16 fl. oz./A for perennial grasses. When both grass and broadleaf weeds are the target pest, VAQUERO may
be tank mixed with 2,4-D ester, Dicamba ® SG or Banvel ® SGF Herbicide, or other broadleaf herbicides for
broad-spectrum control. When both annual and perennial grasses occur in the same field, use a minimum of 8
fl. oz./A VAQUERO rate.

42

x Use a minimum spray volume of 15 gallons/A for ground applicat ions and 5 gallons/A for aerial applications.
x Apply only to actively growing g rasses when the first grass re aches the recommended weed height as
specified by the Use Directions for Annual and Perennial Grasses section of this label.
x Annual grasses which emerge after the VAQUERO application will not be controlled, and a second
application may be necessary.
x The control of perennial grasses may require more than one application in non-tilled areas.

RESTRICTIONS:
x Do not plant any crop for 30 days after application unless cle thodim is registered for use in that crop.
x Do not apply to grasses that have tillered, formed seedheads or exceeded recommended growth stage.
x Do not use flood jet nozzles.

ORNAMENTALS: DIRECTIONS FOR USE
For ornamental plant uses, VAQUERO can be used to control labeled grass weeds in greenhouses, lathhouses,
shadehouses, and around outdoor ornamentals, including nurserie s, parks, roadside plantings, and structure
landscapes.
IMPORTANT: VAQUERO successfully controls weeds in newly transplanted and established non-grassy
ornamentals. Plant tolerance to VAQUERO at labeled rates has be en found to be acceptable for the indicated
genera and species listed below. Due to variability within spec ies, crop growth stage, environmental conditions,
and application techniques, it is recommended that the user det ermine if herbicide can be used safely on a few
plants prior to widespread application. Neither the seller nor the manufacturer of VAQUERO have investigated
the safety factor to ornamental plants not listed on the label.
