PERSONAL PROTECTIVE EQUIPMENT (PPE)
Applicators and other handlers must wear:
Long-sleeved shirt and long pants
Chemical resistant gloves made of any waterproof material such as polyethylene or polyvinyl chloride. 
Shoes plus socks
Discard clothing and other absorbent materials that have been drenched, or heavily contaminated with this product. 
Follow manufacturer’s instructions for cleaning/maintaining PPE. If no such instruction for washables exists, use detergent 
and hot water. Keep and wash PPE separately from other laundry.

2
IMPORTANT : When reduced PPE is worn because a closed system is being used, handlers must be provided all 
PPE specified above for "applicators and other handlers" and have such PPE immediately available for use in an 
emergency, such as a spill or equipment break-down.
ENGINEERING CONTROL
When handlers use closed systems, enclosed cabs, or aircraft in a manner that meets the requirements listed in the 
Worker Protection Standard (WPS) for agricultural pesticides (40 CFR 170.240(d)(4-6), the handler PPE 
requirements may be reduced or modified as specified in the WPS.
ENVIRONMENTAL HAZARDS
Do not apply directly to water, to areas where surface water is present or to intertidal areas below the mean 
highwater mark. Do not apply when weather conditions favor drift from areas treated. Do not contaminate water 
when disposing of equipment washwaters or rinsate.
Groundwater Advisory
Metribuzin is a chemical which can travel (seep or leach) through soil and can contaminate groundwater which may 
be used as drinking water. Metribuzin has been found in groundwater as a result of agricultural use. Users are 
advised not to apply metribuzin where the water table (groundwater) is close to the surface, and where the soils are 
very permeable, i.e., well drained soils such as loamy sands. Yom local agricultural agencies can provide further 
information on the type of soil in your area and the location of groundwater.
Surface Water Advisory
This product may impact surface water quality due to runoff of rain water. This is especially true for poorly draining 
soils and soils with shallow ground water. This product is classified as having high potential for reaching surface 
water via runoff for several weeks or more after application. A level, well-maintained vegetative buffer strip 
between areas to which this product is applied and surface water features such as ponds, streams, and springs will 
reduce the potential loading of this product from runoff water and sediment. Runoff of this product will be greatly 
reduced by avoiding applications when rainfall or irrigation is expected to occur within 48 horns.
Windblown Soil Particles Advisory
This product has the potential to move off-site due to wind erosion. Soils that are subject to wind erosion usually 
have a high silt and/or fine to very fine sand fractions and low organic matter content. Other factors which can affect 
the movement of windblown soil include the intensity and direction of prevailing winds, vegetative cover, site slope, 
rainfall, and drainage patterns. Avoid applying this product if prevailing local conditions may be expected to result 
in off-site movement.
Non-target Organism Advisory
This product is toxic to plants and may adversely impact the forage and habitat of non-target organisms, including 
pollinators, in areas adjacent to the treated area. Protect the forage and habitat of non-target organisms by 
minimizing spray drift. For further guidance and instructions on how to minimize spray drift, refer to the Spray Drift 
Management section of this label.
USER SAFETY RECOMMENDATIONS
USERS SHOULD: Wash thoroughly with soap and water after handling and before eating, drinking, chewing 
gum, using tobacco or using the toilet. Remove clothing/PPE immediately if pesticide gets inside. Then wash 
thoroughly and put on clean clothing. Remove PPE immediately after handling this product. Wash the outside of 
gloves before removing. As soon as possible, wash thoroughly and change into clean clothing.
DIRECTIONS FOR USE
It is a violation of Federal law to use this product in a manner inconsistent with its labeling.
DO NOT apply this product in a way that will contact workers or other persons, either directly or through drift. Only 
protected handlers may be in the area during application. For any requirements specific to your State or Tribe, consult the 
agency responsible for pesticide regulation.

BIOLOGICAL ACTIVITY
CANSIO herbicide is absorbed through the foliage and roots of plants rapidly inhibiting the growth of susceptible weeds. 
One to 3 weeks after application to weeds (2 to 5 weeks for wild garlic), leaves of susceptible plants appear chlorotic, and 
the growing point subsequently dies. Following application of CANSIO herbicide susceptible weeds may germinate and 
emerge, but growth then ceases, and leaves become yellow and/or brown 3-5 days after emergence. Death of leaf tissue 
and growing point will follow in some species while others will remain green but stunted and noncompetitive. 
CANSIO herbicide provides the best control in vigorously growing crops that shade competitive weeds. Weed control in 
areas of thin crop stand or seeding skips may not be as satisfactory. However, a crop canopy that is too dense at application 
can intercept spray and reduce weed control.
The herbicidal action of CANSIO herbicide may be affected in crops stressed from adverse environmental conditions 
(including extreme temperatures or moisture), abnormal soil conditions, cultural practices, or variations in crop variety. In 
warm, moist conditions, the expression of herbicide symptoms is accelerated; in cold, dry conditions, expression of 
herbicide symptoms is delayed. In addition, weeds hardened-off by drought stress are less susceptible to CANSIO 
herbicide.
PRODUCT INFORMATION
CANSIO herbicide is a water dispersible granule that can be applied alone or in combination with other herbicides for 
selective control of broadleaf weeds and grasses in spring and winter barley, winter wheat, fallow and bumdown. 
When applied according to instructions on this label the best control is obtained when CANSIO herbicide is applied to 
young, actively growing weeds. The specified use rate will depend on weed spectrum and size of weed at time of 
application.
Residual applications of CANSIO herbicide require rainfall or sprinkler irrigation to activate the herbicide. Degree of 
control and duration of effect depend on; rate used, weed spectrum, growing conditions at and following time of 
treatment, weed size, soil pH, texture, organic matter, moisture and precipitation.
Best residual control is obtained if CANSIO herbicide is applied to moist soil and followed by rainfall or irrigation (~1”) 
before weeds germinate. Several small rainfalls of less than 1/4” each are not as beneficial as one large rainfall of 1/2-1”. 
On dry soil, more moisture is required for activation (1-2”) before weed emergence. If moisture is insufficient to activate 
the herbicide, a rotary hoeing or shallow cultivation needs to be made after emergence of the crop while weeds are small 
enough to be controlled by mechanical means. If heavy rains occur within 3 weeks of planting, crop injury may result.
RESTRICTIONS

WEED RESISTANCE MANAGEMENT
CANSIO herbicide, which contains the active ingredients metribuzin, thifensulfuron-methyl and tribenuron-methyl are group 
2 or 5 herbicides based on the mode of action classification system of the Weed Science Society of America.
Proactively implementing diversified weed control strategies to minimize selection for weed populations resistant to one or 
more herbicides is a best practice. A diversified weed management program may include the use of multiple herbicides 
with different sites of action and overlapping weed spectrum with or without tillage operations and/or other cultural 
practices. Research has demonstrated that using the labeled rate and directions for use is important to delay the selection 
for resistance.
The continued effectiveness of this product depends on the successful implementation of a weed resistance management 
program.
To aid in the prevention of developing weeds resistant to this product, users should;
• Scout fields before application to ensure herbicides and rates will be appropriate for the weed species and weed sizes 
present.
• Start with a clean field, using either a bumdown herbicide application or tillage.
• Control weeds early when they are relatively small (less than 4 inches).
• Apply full rates of CANSIO herbicide, for the most difficult to control weed in the field at the specified time (correct 
weed size) to minimize weed escapes.
• Scout fields after application to detect weed escapes or shifts in control of weed species.
• Control weed escapes before they reproduce by seed or proliferate vegetatively.
• Report any incidence of non-performance of this product against a particular weed to your FMC representative, local 
retailer, or county extension agent.
• Contact your FMC representative, crop advisor, or extension agent to find out if suspected resistant weeds to these 
MO As have been found in your region. Do not assume that each listed weed is being controlled by multiple sites of 
action. Products with multiple active ingredients are intended to broaden the spectrum of weeds that are controlled. Some 
weeds may be controlled by only one of the active ingredients in this product.
• If resistance is suspected, treat weed escapes with an herbicide having a site of action other than Group 2 or 5 
and/or use nonchemical methods to remove escapes, as practical, with the goal of preventing further seed 
production.
• Suspected herbicide-resistant weeds may be identified by these indicators:
- Failure to control a weed species normally controlled by the herbicide at the dose applied, especially if control is 
achieved on adjacent weeds;
- A spreading patch of non-controlled plants of a particular weed species; and
- Surviving plants mixed with controlled individuals of the same species
Additionally, users should follow as many of the following herbicide resistance management practices as is practical:
• Use a broad-spectrum soil-applied herbicide with other sites of action as a foundation in a weed control program.
• Utilize sequential applications of herbicides with alternative sites of action.

TANK MIX COMPATIBILITY TESTING
Perform a jar test prior to tank mixing to ensure compatibility of CANSIO herbicide and other pesticides. Use a clear glass 
quart jar with lid and mix the tank mix ingredients in their relative proportions. Invert the jar containing the mixture 
several times and observe the mixture for approximately 1/2 hour. If the mixture balls-up, forms flakes, sludges, gels, oily 
film or layers, or other precipitates, it is not compatible.
Tank Mixing - The crop safety of all tank mixtures with CANSIO herbicide which may include physically compatible 
pesticides, fertilizers, adjuvants, and/or additives, has not been tested. When considering the use of a tank mixture on a 
labeled crop without prior experience, or which is not specifically described in the CANSIO herbicide product labeling or 
in other FMC product use instruction, it is important to first understand crop safety. To test for crop safety, prepare a small 
volume of the intended tank mixture, apply it to an area of the target crop as directed by both this and the tank mix partner 
product label(s) and observe the treated crop to ensure that a phytotoxic response does not occur. FMC will not be 
responsible for any crop injury arising from the use of a tank mixture that is not specifically described on the CANSIO 
herbicide product labeling or in other FMC product use instructions.
This product may be tank mixed with registered products for these uses including products containing the active 
ingredients 2,4-D, bromoxynil, dicamba, glufosinate, glyphosate, MCPA, paraquat, or saflufenacil in accordance with the 
most restrictive label limitations and precautions. DO NOT exceed label dosage rates. This product may not be mixed with 
any product containing a label prohibition against such mixing. Refer to crop specific information section of this label for 
additional information.
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. If the 
instructions on the tank mix partner label conflicts with this CANSIO herbicide label, DO NOT use in a tank mixture with 
CANIO herbicide.
SOIL TEXTURE: As used on this label, “Coarse soils” are loamy sand or sandy loam soils. “Medium soils” are loam, silt
loam, silt, sandy clay, or sandy clay loam. “Fine soils” are silty clay, silty clay loam, clay, or clay loam. Silty clay loam soils

INTEGRATED PEST MANAGEMENT
This product may be used as part of an Integrated Pest Management (IPM) program that can include biological, cultural, 
and genetic practices aimed at preventing economic pest damage. IPM principles and practices include field scouting or 
other detection methods, correct target pest identification, population monitoring, and treating when target pest 
populations reach locally determined action thresholds. Consult your state cooperative extension service, professional 
consultants or other qualified authorities to determine appropriate action treatment threshold levels for treating specific 
pest/crop systems in your area.
• Rotate the use of this product with non-Group 2 or 5 herbicides.
• Avoid making more than two applications of CANSIO herbicide, and any other Group 2 or 5 herbicides within a 
single growing season unless mixed with an herbicide with a different site of action with an overlapping spectrum for 
the difficult-to- control weeds.
• Incorporate non-chemical weed control practices, such as mechanical cultivation, crop rotation, cover crops and weed- 
free crop seeds, as part of an integrated weed control program.
• Use good agronomic principles that enhance crop development and crop competitiveness.
• Thoroughly clean plant residues from equipment before leaving fields suspected to contain resistant weeds.
• Manage weeds in and around fields, during and after harvest to reduce weed seed production.
USE INFORMATION
MIXING: When using CANSIO herbicide, make sure the sprayer is completely clean and free of rust or corrosion 
which occurs from winter storage. Examine strainers and screens to be sure the sprayer is clean from previously used 
pesticides.
Any tank-mix containing CANSIO herbicide needs to be kept agitated and sprayed out immediately. DO NOT allow tank­
mixes to stand for prolonged periods of time.
The proper mixing procedures for CANSIO herbicide alone or in tank-mix combinations with other herbicides is:
1. Fill the spray tank 1/4 to 1/3 full with clean water.
2. Add specified rate of CANSIO herbicide while recirculating and with agitatorrunning.

SPRAY DRIFT MANAGEMENT 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 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.
Controlling Droplet Size — Ground Boom
• Volume - Increasing the spray volume so that larger droplets are produced will reduce spray drift. Use the highest 
practical spray volume for the application. If a greater spray volume is needed, consider using a nozzle with a higher 
flow rate.
• Pressure - Use the lowest spray pressure recommended for the nozzle to produce the target spray volume and droplet 
size.
• Spray Nozzle - Use a spray nozzle that is designed for the intended application. Consider using nozzles designed to 
reduce drift.
Controlling Droplet Size — Aircraft
• Adjust Nozzles - Follow nozzle manufacturers recommendations for setting up nozzles. Generally, to reduce fine 
droplets, nozzles should be oriented parallel with the airflow in flight.
BOOM HEIGHT - Ground Boom
Use the lowest boom height that is compatible with the spray nozzles that will provide uniform coverage. For ground 
equipment, the boom should remain level with the crop and have minimal bounce.

BOOM-LESS GROUND APPLICATIONS:
• Setting nozzles at the lowest effective height will help to reduce the potential for spray drift.
DRIFT CONTROL ADDITIVES
Using product compatible drift control additives can reduce drift potential. When a drift control additive is used, read and 
careftilly observe cautionary statements and all other information on the additive’s label. If using an additive that increases 
viscosity, ensure that the nozzles and other application equipment will function properly with a viscous spray solution.
Preferred drift control additives have been certified by the Council of Producers & Distributors of Agrotechnology 
(CPDA).
HANDHELD TECHNOLOGY APPLICATIONS: 
• Take precautions to minimize spray drift.
RELEASE HEIGHT - Aircraft
Higher release heights increase the potential for spray drift. When applying aerially to crops, do not release spray at a 
height greater than 10 ft above the crop canopy, unless a greater application height is necessary for pilot safety. 
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. 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.
APPLICATION OF CANSIO HERBICIDE WITH HERBICIDE SPRAY EQUIPMENT
Use a standard low pressure (20 to 40 psi.) herbicide boom sprayer equipped with suitable nozzles and screens no finer 
than 50-mesh in nozzle and in-line strainers. Agitate thoroughly before and during application with bypass agitation. 
GROUND APPLICATION: Apply the proper rate of CANSIO herbicide in a minimum of 10 to 40 gallons of spray 
mixture per acre broadcast.
Banded Application; Use proportionally less CANSIO herbicide per acre in a band versus a broadcast application. For band 
application use 1/4 to 1 gallon of spray mix per inch of band width regardless of row spacing.
AERIAL APPLICATION: Where permitted, apply specified rate in a minimum of 2 to 10 gallons of spray mixture per 
acre.
Restriction: Aerial application is not permitted in the State of New York.
For All Applications of CANSIO herbicide; Sprayer must be accurately calibrated before applying CANSIO herbicide. 
Check sprayer during application to be sure it is working properly and delivering a uniform spray pattern. As the volume 
of spray mixture decreases per acre, the importance of accurate calibration and uniform application increases. Avoid other 
application, misapplication, and boom and spray swath overlapping that will increase spray dosage. (Crop injury may 
occur as a result). Avoid spray skips and gaps which allow weeds to grow in untreated soil.
SPRAYER CLEANUP; Spray equipment must be thoroughly cleaned to remove remaining traces of herbicide that might 
injure other crops to be sprayed. Drain any remaining spray solution of CANSIO herbicide from the spray tank and dispose 
of according to label disposal instructions. Rinse the spray tank and refill with water, adding a heavy-duty detergent at the 
rate of one cup per 20 gallons of water. Recycle this mixture through the equipment for 5 minutes and spray out. Repeat this 
procedure twice. Fill the spray tank with clean water, recycle for 5 minutes, and spray out. Clean pump and nozzle screens 
thoroughly. Wash away spray mixture from the outside of spray tank, nozzles or spray rig. All rinse water must be disposed 
of in compliance with local, state, and Federal guidelines.
APPLICATION OF CANSIO HERBICIDE IN FLUID FERTILIZERS
Crop injury may occur when CANSIO herbicide is applied in fluid fertilizer solutions. Follow the appropriate mixing 
procedures and compatibility check if you chose to apply CANSIO herbicide in fluid fertilizer solutions. When using tank­
mix combinations, be sure all components are compatible. Compatibility checks of CANSIO herbicide and tank-mix 
combinations which include CANSIO herbicide needs to be made for each batch of fluid fertilizer because of the 
variability of these fertilizers. 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. If the instructions on the tank mix partner label conflict with this CANSIO herbicide label, DO

Compatibility Check:
1. Pre-mix 2 teaspoons of CANSIO herbicide with 8 teaspoons of water (1:4 ratio) in a quart jar by adding the water 
first and follow with CANSIO herbicide. Mix thoroughly, if a second herbicide is to be used, double the amount of 
water (1:8 ratio) and add the second herbicide after mixing CANSIO herbicide first.
2. Then pour 1 pint of fluid fertilizer into the quart jar and shake well.
3. Allow to stand for 5 minutes.
THIS COMPATIBILITY CHECK MUST ONLY BE USED WHEN MIXING WITH FLUID FERTILIZERS. 
Interpretation of Results: If the solution in the jar appears to be uniform, without signs of agglomeration, or without a 
separation of an oily film on top of the fertilizer, the mixture may be used. If not, repeat the compatibility check using twice 
the amount of water or add a compatibility agent to the water. If separation occurs, but the mixture can be resuspended by 
shaking, then application is possible with good agitation in the spray tank.
Tank-mixing Guidelines:
1. Add the required amount of water and compatibility agent (if required) to the tank. Start agitation while adding 
CANSIO herbicide and follow by adding the fluid fertilizer and agitate.
2. If a second herbicide is to be used, follow as above in 1, but use twice the amount of water. Start agitation and add 
CANSIO herbicide and follow by adding the second herbicide, and then continue filling the tank with fluid 
fertilizer.
3. Maintain continuous agitation to ensure uniform spray mixture until the tank is emptied.
SPRING AND WINTER BARLEY AND WINTER WHEAT
CANSIO herbicide may be used for control or suppression of certain grasses and broadleaf weeds when applied 
postemergence to spring and winter barley or winter wheat at initial tillering to just before jointing. CANSIO herbicide 
may be used alone or in a tank-mixture in the following states: AR, DE, GA, ID, IL, IN, KS, KY,LA, MD, MS, MO, MT, 
NC, NV, OH, OK, OR, PA, SC, TN, TX, UT, VA, and WA.
Mixing: See the “Use Information” section of this label for specific mixing procedures. When tank-mixing, carefully 
follow the instructions on this label. Refer to the other product labels registered for use in barley and winter wheat for 
additional use directions, rates, weeds controlled and restrictions. 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. If the instructions on the tank mix partner label 
conflict with this CANSIO herbicide label, DO NOT use in a tank mixture with CANSIO herbicide.
Application: CANSIO herbicide may be applied by aerial (except in the state of New York), or ground application 
equipment. Use a minimum spray volume of 2 gpa by air and 10 gpa by ground. Uniform spray coverage is necessary to 
obtain optimum weed control and to minimize potential for crop injury. Apply CANSIO herbicide when the crop is healthy 
and actively growing.
On irrigated barley and wheat, apply 0.5 inch or less of water for the first irrigation, the maximum amount for each 
additional irrigation must not exceed 1 inch. Allow a minimum of 14 days between the first irrigation and subsequent 
inigations.
Performance Factors: Weed control may not be observed for 2 to 4 weeks under normal growth conditions and for 4 to 6 
weeks under very dry conditions. Moisture (at least 1/2 inch) is required within 2 to 3 weeks after application to move 
CANSIO herbicide into the weed root zone. Lack of adequate moisture after application may result in poor or erratic weed 
control. Control or suppression of listed weeds is dependent on weed size at time of application. Control or suppression 
may be reduced if broadleaf weeds are taller than 1 inch or grasses have more than 2 leaves.
Tank-mixtures: CANSIO herbicide may be tank-mixed with full or reduced rates of other herbicide, insecticide, and 
fungicide products registered for use in the specified crops. Consult tank mix partner labeling for rate and crop rotation 
restrictions. 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. 
If the instructions on the tank mix partner label conflicts with this CANSIO herbicide label, DO NOT use in a tank 
mixture with CANSIO herbicide. Ensure the tank mix product is labeled for the same timing, method of application, 
adjuvants, and use restrictions as CANSIO herbicide, as well as other products used in the tank mixture.
Weed control and crop safety resulting from the use of tank mixtures not specifically noted on this label, or in separately 
published FMC information, are the responsibility of the user. For tank-mix combinations, follow the most restrictive label.

WHEAT AND BARLEY VARIETAL SENSITIVITY
Wheat and barley varieties vary in their sensitivity to CANSIO herbicide. To avoid possible crop injury, contact the seed 
supplier or herbicide expert for a variety direction prior to treatment or treat a small strip of the unlisted variety with the 
labeled CANSIO herbicide rate to ascertain crop sensitivity before treating an entire field.
Spring and Winter Barley and Winter Wheat Rotations Following Potatoes Treated with Metribuzin: If planting a 
sensitive variety, following potatoes treated with metribuzin containing products, refer to the potato section of the 
metribuzin label for special cultural practices to follow.
PRECAUTIONS - BARLEY AND WHEAT:
Crop injury may occur if CANSIO herbicide is applied:
1 When the crop is under stress including winter kill, frost damage, prolonged cold weather, wide fluctuations in day/night 
temperatures, disease, insect damage, drought or excessive moisture, severe grazing, low fertility or when these 
conditions follow the application.

Dandelion: For best results, apply 3.5 to 4.2 ounces CANSIO
herbicide per acre plus surfactant before flowering. The addition of
2,4-D or MCPA may improve control of heavy populations, stressed 
weeds, and larger weeds.
Kochia, Russian thistle, Prickly lettuce: Naturally occurring SU resistant biotypes of these weeds are known to occur. 
For best results, use CANSIO herbicide in a tank mix with registered for this use containing the active ingredients 
including dicamba and 2,4-D; or bromoxynil and 2,4-D. CANSIO herbicide needs to be applied in the spring when weeds 
are less than 2” tall or 2” across and are actively growing.
Vetch (common and hairy): For control in wheat and barley, use 3.5
to 4.2 oimces of CANSIO herbicide per acre plus surfactant when vetch 
is less than 6” in length. For severe infestations of vetch, or when vetch 
is greater than 6” in length, use CANSIO herbicide in combination with
2,4-D or MCPA.
Wild garlic: CANSIO herbicide may provide reduced control of wild 
garlic as compared to HARMONY® EXTRA. For best control in 
wheat and barley, use 3.5 to 4.2 ounces CANSIO herbicide per acre 
plus surfactant when wild garlic plants are less than 12” tall with 2” to
4” of new growth. Plants hardened-off by cold weather and/or drought 
stress may be more difficult to control.
Thorough spray coverage of all garlic plants is essential. Typical
symptoms of dying garlic plants may not be noticeable for 2 to 5 
weeks.
