SIGNAL F Herbicide is a systemic, postemergence herbicide for the control of kochia, cleavers, wild oats, green foxtail, yellow foxtail, barnyard grass, volunteer oats, volunteer canary seed and suppression of wild buckwheat in wheat (spring and durum) in the Prairie Provinces and the Peace River Region of British Columbia. Thorough coverage of the plants is essential for consistent control. SIGNAL F Herbicide can be tank-mixed with 2,4-D and MCPA herbicides to provide a broader spectrum of weed control. Refer to the appropriate tank mix sections.

Sensitive Plants 
Do not apply SIGNAL F Herbicide directly to, or otherwise permit it to come in direct contact with susceptible crops or desirable plants including alfalfa, edible beans, canola, flowers and ornamentals, lentils, lettuce, peas, potatoes, radishes, soybeans, sugar beets, sunflowers, tomatoes or tobacco. 
Non-Target Sites 
Do not apply where proximity of susceptible crops or other desirable plants is likely to result in exposure to spray or spray drift. See the Environmental Hazards section of the label. 
Crop Rotation 
Fields previously treated with SIGNAL F Herbicide can be seeded the following year to barley, canola, flax, forage grasses, lentils, mustard, oats, peas, rye or wheat or fields can be summerfallowed.

Buffer Zones 
The buffer zones specified in the table below are required between the point of direct application and the closest downwind edge of sensitive terrestrial habitats (such as grasslands, forested areas, shelter belts, woodlots, hedgerows, riparian areas and shrublands), sensitive freshwater habitats (such as lakes, rivers, sloughs, ponds, prairie potholes, creeks, marshes, streams, reservoirs and wetlands) and estuarine/marine habitats.

Tank Mixtures 
In some cases, tank mixing a pest control product with another pest control product or a fertilizer can result in biological effects that could include, but are not limited to: reduced pest efficacy or increased host crop injury. The user should contact Nufarm Agriculture Inc. at 1-800-868-5444 for information before mixing any pesticide or fertilizer that is not specifically recommended on this label. The user assumes the risk of losses that result from the use of tank mixes that do not appear on this label or that are not specifically recommended by Nufarm Agriculture Inc. When a tank mixture is used, consult the labels of the tank mix partners and observe the largest (most restrictive) buffer zone of the products involved in the tank mixture. Refer to the tank mix partner herbicide label for further precautions, restrictions and use instructions. 

Spray Equipment Precaution 
Do not apply through any type of irrigation system. 

To Reduce Spray Drift: 
Use nozzles delivering higher volumes and coarser droplets.
Use low pressures (200 to 275 kPa).
Use 100 L/ha of spray solution.
Spray when the wind velocity is 15 km/h or less.
Spot treatments should only be applied with a calibrated boom to prevent over-application.

To Reduce Runoff from Treated Areas: 
To reduce runoff from treated areas into aquatic habitats, consider the characteristics and conditions of the site before treatment. Site characteristics and conditions that may lead to runoff include, but are not limited to: heavy rainfall, moderate to steep slope, bare soil, poorly draining soil (e.g. soils that are compacted, fine textured, or low in organic matter such as clay). Avoid application of this product when heavy rain is forecast. Contamination of aquatic areas as a result of runoff may be reduced by including a vegetative strip (buffer zone) between the treated area and the edge of the water body.

Equipment Clean-Up 
Equipment used to apply SIGNAL F Herbicide should not be used to apply other pesticides to sensitive crops without thorough cleaning. Contact your SIGNAL F Herbicide dealer for detailed equipment cleaning procedures.



Crops Registered: Spring wheat, Durum wheat

Apply SIGNAL F Herbicide at 0.5 L/ha with Nufarm Enhance at 0.25%v/v (0.25 L of Nufarm Enhance in 100 L water). 


Application Timing 
Apply to actively growing wheat from the 2-leaf crop growth stage up to and including just prior to the emergence of 4th tiller. Apply when weeds are actively growing. Best results are obtained from applications made to seedling weeds. Only weeds that have emerged at the time of treatment will be controlled.  Extreme growing conditions such as drought or near freezing temperature prior to, at and following time of application may reduce weed control and increase the risk of crop injury at all stages of growth. Foliage that is wet at the time of application may decrease control. SIGNAL F Herbicide applications are rainfast within 1 hour after application. Under conditions of low crop and high weed density, control may be reduced. 

Preharvest/Grazing Intervals (SIGNAL F Herbicide applied alone) 
Livestock may be grazed on treated crops 3 days following application.
Do not harvest the treated crop within 60 days after application.

For resistance management, please note that SIGNAL F Herbicide is a Group 1 and 4 herbicide. Any weed population may contain plants naturally resistant to SIGNAL F Herbicide and Group 1 and 4 herbicides. The resistant biotypes may dominate the weed population if these herbicides are used repeatedly in the same field. Other resistance mechanisms that are not linked to site of action, but specific for individual chemicals, such as enhanced metabolism, may also exist. Appropriate resistance-management strategies should be followed.
To delay herbicide resistance:
Where possible, rotate the use of SIGNAL F Herbicide or other Group 1 and 4 herbicides within a growing season (sequence) or among growing seasons with different herbicide groups that control the same weeds in a field.
Use tank mixtures with herbicides from a different group when such use is permitted. To delay resistance, the less resistance-prone partner should control the target weed(s) as effectively as the more resistance-prone partner.
Herbicide use should be based on an integrated weed management program that includes scouting, historical information related to herbicide use and crop rotation, and considers tillage (or other mechanical control methods), cultural (for example, higher crop seeding rates; precision fertilizer application method and timing to favour the crop and not the weeds), biological (weed-competitive crops or varieties) and other management practices.
Monitor weed populations after herbicide application for signs of resistance development (for example, only one weed species on the herbicide label not controlled). If resistance is suspected, prevent weed seed production in the affected area if possible by an alternative herbicide from a different group. Prevent movement of resistant weed seeds to other fields by cleaning harvesting and tillage equipment when moving between fields, and planting clean seed.
Have suspected resistant weed seeds tested by a qualified laboratory to confirm resistance and identify alternative herbicide options.
Contact your local extension specialist or certified crop advisors for any additional pesticide resistance-management and/or integrated weed-management recommendations for specific crops and weed biotypes.
