PRODUCT INFORMATION:
SIGNAL HERBICIDE is a systemic, post-emergence herbicide for the selective control of wild oats, volunteer (tame) oats, green foxtail, yellow foxtail, barnyard grass, Persian darnel and volunteer canary seed in all types of spring wheat and Durum wheat. Do not use SIGNAL HERBICIDE on barley, as crop injury will occur. Do not apply this product using aerial application equipment except under conditions specified on this label.
SIGNAL HERBICIDE is absorbed by the leaves and is rapidly translocated to the growing points of leaves and stems. Thorough coverage of the plants is essential for consistent control. Actively growing susceptible grasses stop growing within 48 hours of treatment. Depending on species, growing conditions and crop competition, leaves and growing points turn yellow within one to three weeks after application. Further colour changes and loss of vigour will be observed, followed by a browning and complete control three to five weeks after application.
Although SIGNAL HERBICIDE does not control broadleaf weeds, SIGNAL HERBICIDE can be tank-mixed with a wide range of broadleaf herbicides to provide broad spectrum weed control in wheat. It can also be tank mixed with Decis Flowable Insecticide and MATADOR 120EC Insecticide to control grassy weeds and insects and with TILT 250E Fungicide to control grassy weeds and cereal leaf diseases. See section entitled “TANK MIXES of SIGNAL HERBICIDE WITH BROADLEAF WEED HERBICIDES, INSECTICIDES AND FUNGICIDES” and refer to the appropriate Tank Mix section for ground and aerial application.

DIRECTIONS FOR USE: 
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. 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.

CROPS: 
Spring Wheat and Durum Wheat SIGNAL HERBICIDE can be used on all varieties of spring wheat and Durum wheat. Observe minimum interval to harvest of 60 days after treatment. Do not apply on barley or any crop other than Spring Wheat or Durum wheat, as crop damage will result. Do not allow spray to drift to adjacent fields seeded to crops other than spring wheat or Durum wheat. Do not treat wheat underseeded to forages. Observe a minimum of three (3) days before grazing livestock on crops treated with SIGNAL HERBICIDE. For use directions specific to application by air, please refer to sections on aerial application. For aerial application precautions, please refer to the precautions section.

WEEDS CONTROLLED: 
Wild Oats, Volunteer (Tame) Oats, Green Foxtail, Yellow Foxtail, Barnyard grass, Persian Darnel and Volunteer Canary Seed

TIMING OF APPLICATION:
For optimum results, apply SIGNAL HERBICIDE to actively growing weeds. An early application will maximize crop yields by reducing weed competition. Weeds emerging after application of SIGNAL HERBICIDE will not be controlled. Weed control following application of SIGNAL HERBICIDE alone, or in combination with broadleaf weed herbicides, can be reduced or delayed under stress conditions such as drought, heat, insufficient fertility, flooding or prolonged cool temperatures. Grass escapes or re-tillering may occur if application is made during prolonged stress conditions. Optimum weed control will be obtained if application of SIGNAL HERBICIDE is delayed until the stress conditions have ended and weeds are once again actively growing. SIGNAL HERBICIDE alone can be used 30 minutes before rainfall. Do not apply to crop that is stressed by conditions such as frost, low fertility, drought, flooding, disease or insect damage as crop injury may result.

TANK MIXES of SIGNAL HERBICIDE WITH BROADLEAF WEED HERBICIDES, INSECTICIDES AND FUNGICIDES – GROUND APPLICATION:

CROP: SPRING and DURUM WHEAT
TANK MIXES WITH BROADLEAF WEED HERBICIDES, INSECTICIDES AND FUNGICIDES IN SPRING WHEAT and DURUM WHEAT: 
For broad spectrum control of wild oats, green foxtail, barnyard grass, Persian Darnel and broadleaf weeds, SIGNAL HERBICIDE Tank Mix can be tankmixed with broadleaf herbicides as described in the following tables. SIGNAL HERBICIDE Tank Mix can also be tank-mixed with Decis Flowable Insecticide and MATADOR 120EC Insecticide for control of insects listed on the Decis Flowable Insecticide and MATADOR 120EC Insecticide label and with TILT 250E Fungicide for control of diseases listed on the TILT 250E Fungicide label, in addition to grassy weeds. Consult the label of the tank-mix partner for a list of broadleaf weeds, insects or diseases controlled, rates, timing, recropping restrictions, grazing interval restrictions, recommendations for specific weeds/insects/ diseases, directions for use and precautions and follow the more restrictive label. When tank-mixing always add the broadleaf herbicide(s), insecticide or fungicide to the spray tank first; followed by SIGNAL HERBICIDE, with SIGNAL ADJUVANT or NUFARM ENHANCE added last. For the appropriate rate of SIGNAL HERBICIDE with SIGNAL ADJUVANT or NUFARM ENHANCE, refer to the `Rate of Use’ section of the label.

TANK MIXES of SIGNAL HERBICIDE WITH BROADLEAF WEED HERBICIDES - AERIAL APPLICATION:

CROP: SPRING WHEAT and DURUM WHEAT 
For broad spectrum control of wild oats, green foxtail and broadleaf weeds, SIGNAL HERBICIDE can be tank-mixed with Buctril M. Consult the label of the tank-mix partner for a list of broadleaf weeds controlled, rates, timing, recropping restrictions, grazing interval restrictions, recommendations for specific weeds, directions for use and precautions and follow the more restrictive label.

2. If a broadleaf herbicide, insecticide or fungicide is to be used, add the product FIRST prior to adding SIGNAL HERBICIDE and agitate for 2-3 minutes.
3. Add correct amount of SIGNAL HERBICIDE.
4. Agitate for 2-3 minutes.
5. Add correct amount of SIGNAL ADJUVANT or NUFARM ENHANCE.
6. Agitate for 1-2 minutes before adding remainder of water and then maintain constant agitation.
7. After any break in spraying operations, agitate thoroughly before spraying again.
8. Use the spray suspension as soon as it is prepared.
9. If an oil film starts to build up in the tank, drain tank and then clean with a detergent.

SPRAYING INSTRUCTIONS - GROUND APPLICATION: 
1. SIGNAL HERBICIDE can be applied by ground or air. For aerial application instructions, refer to the section entitled “SPRAYING INSTRUCTIONS - AERIAL APPLICATION” which follows this section.
2. Water Volume: 50 to 100 litres per hectare when applied alone and a minimum of 100L/ ha when tank-mixed with broadleaf herbicides
3. Spray Nozzles: 80 or 110 flat fan stainless steel nozzles are recommended for optimal spray coverage. Application of the spray mixture at a 45 angle in the direction of travel will result in improved spray coverage. Use 50 mesh nozzle screens. Do not use flood type nozzles, controlled droplet application equipment, spray foils or hollow cone nozzles.
4. Pressure: 275-310 kPa.
5. Apply uniformly at 6-8 km/hr and avoid overlapping. Shut off spray boom while starting, turning, slowing or stopping to prevent crop injury from an over application.
6. Do not contaminate streams, rivers, lakes, ponds, wetlands, sloughs, irrigation water, vegetated ditch banks, and water used by livestock or for domestic purposes. Do not apply within 15 meters of a wetland area or any of the aforementioned bodies of water.

AERIAL APPLICATION: 

Generic Aerial Application Label Instructions - Directions for Use 
Apply only by fixed-wing or rotary aircraft equipment which has been functionally and operationally calibrated for the atmospheric conditions of the area and the application rates and conditions of this label. Label rates, conditions and precautions are product specific. Read and understand the entire label before opening this product. Apply only at the rate recommended for aerial application on this label. Where no rate for aerial application appears for the specific use, this product cannot be applied by any type of aerial equipment. Ensure uniform application. To avoid streaked, uneven or overlapped application, use appropriate marking devices.

Use Precautions 
Apply only when meteorological conditions at the treatment site allow for complete and even crop coverage. Apply only under conditions of good practice specific to aerial application as outlined in the National Aerial Pesticide Application Manual, developed by the Federal/ Provincial/Territorial Committee on Pest Management and Pesticides. Do not apply to any body of water. Avoid drifting of spray onto any body of water or other non-target areas. Specified buffer zones should be observed. Coarse sprays are less likely to drift, therefore, avoid combinations of pressure and nozzle type that will result in fine particles (mist). Do not apply during periods of dead calm or when wind velocity and direction pose a risk of spray drift. Do not spray when the wind is blowing towards a nearby sensitive crop, garden, terrestrial habitat (such as shelter-belt) or aquatic habitat.

Operator Precautions 
Do not allow the pilot to mix chemicals to be loaded onto the aircraft. Loading of premixed chemicals with a closed system is permitted. It is desirable that the pilot have communication capabilities at each treatment site at the time of application. The field crew and the mixer/loaders must wear chemical resistant gloves, coveralls and goggles or face shield during mixing/loading, cleanup and repair. Follow the more stringent label precautions in cases where the operator precautions exceed the generic label recommendations on the existing ground boom label. All personnel on the job site must wash hands and face thoroughly before eating and drinking. Protective clothing, aircraft cockpit and vehicle cabs must be decontaminated regularly. Product Specific Precautions Read and understand the entire label before opening this product. If you have questions, call the manufacturer at 1-800-868-5444 or obtain technical advice from the distributor or your provincial agricultural representative. Application of this specific product must meet and/or conform to the following:

MIXING INSTRUCTIONS - AERIAL APPLICATION: 
1. Fill the mixing tank 1/2 full with clean water. Start gentle agitation.
2. If a broadleaf herbicide is to be used, add the product FIRST prior to adding SIGNAL HERBICIDE and agitate for 2-3 minutes.
3. Add correct amount of SIGNAL HERBICIDE.
4. Agitate for 2-3 minutes.
5. Add correct amount of SIGNAL ADJUVANT or NUFARM ENHANCE.
6. Agitate for 1-2 minutes before adding remainder of water and then maintain constant agitation.
7. Fill aircraft spray tank and maintain gentle agitation while spraying.
8. After any break in spraying operations, agitate thoroughly before spraying again. Do not let contents stand without agitation.
9. Use the spray suspension as soon as it is prepared.
10. If an oil film starts to build up in the tank, drain tank and then clean with a detergent.

SPRAYING INSTRUCTIONS - AERIAL APPLICATION: 
1. SIGNAL HERBICIDE can be applied by ground or by air. For ground application instructions, refer to the section entitled “SPRAYING INSTRUCTIONS - GROUND APPLICATION” which precedes this section.
2. Water Volume - Aerial application: Minimum of 30 litres per hectare when applied alone or when tank mixed with Buctril M.
3. When applying by aircraft, applicators are required to use spray nozzles or nozzle configurations and spraying pressures which will provide a COARSE droplet size distribution, with a volume medium diameter (VMD) greater than 350 microns.
4. Aerial drift is increased under certain meteorological conditions. Do not apply during periods of dead calm, when winds are gusty or when wind speed is greater than 15 km/hr.
5. For the protection of non-target habitats, overspray or drift to sensitive habitats must be avoided. A buffer zone of 76 metres is required between the downwind edge of the boom and sensitive terrestrial habitats including grasslands, forested areas, shelter belts, woodlots, hedgerows and shrublands. A buffer zone of 72 meters is required between the downwind edge of the boom and sensitive aquatic habitats such as sloughs, ponds, prairie potholes, lakes, rivers, streams and irrigation ditches, and the vegetation surrounding wetlands. Do not contaminate these habitats when cleaning and rinsing spray equipment or containers.
6. When a tank mixture is used, consult the label of the tank-mix partners and observe the largest (most restrictive) buffer zone of the products involved in the tank mixture.
7. Ensure uniform application. To avoid uneven or overlapped application, use appropriate marking devices. Do not use human flaggers.

SPRAYER CLEAN-UP: 
1. Thoroughly clean application equipment immediately after spraying. Ensure that all traces of the product are removed. The following recommendations are provided:
2. Drain and flush tank walls, boom and all hoses for ten minutes with clean water. Do not clean the sprayer near desirable vegetation, wells, or other water sources.
3. Remove the nozzles and screens and wash separately.
4. Dispose of all rinsings in accordance with provincial regulations.
5. If a broadleaf tank-mix partner is used, always check tank-mix partner label for any additional clean up procedures.

RESISTANCE-MANAGEMENT RECOMMENDATIONS: 
For resistance management, SIGNAL HERBICIDE is a Group 1 herbicide. Any weed population may contain or develop plants naturally resistant to SIGNAL HERBICIDE and other Group 1 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 resistancemanagement strategies should be followed.
To delay herbicide resistance:
Where possible, rotate the use of SIGNAL HERBICIDE or other Group 1 herbicides 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.
Herbicide use should be based on an IPM program that includes scouting, historical information related to herbicide use and crop rotation, and considers tillage (or other mechanical), cultural, biological and other chemical control practices.
Monitor treated weed populations for resistance development.
Prevent movement of resistant weed seeds to other fields by cleaning harvesting and tillage equipment and planting clean seed.
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.
