COMMERCIAL (AGRICULTURAL)
FOR SALE FOR USE IN THE PRAIRIE PROVINCES AND PEACE RIVER REGION OF BRITISH COLUMBIA ONLY
1.0 GENERAL INFORMATION
HEAT WG is a water soluble granular herbicide for broadleaf weed control.
HEAT WG is rapidly absorbed by root and foliar uptake; once absorbed it exhibits mobility in plants. HEAT WG is a potent inhibitor of protoporphyrinogen oxidase (PPO). Cell membrane damage induced by inhibition of PPO leads to plant death. Susceptible weeds develop injury symptoms within hours of application under active growing conditions; plant death occurs within 3 to 5 days depending upon growing conditions.
HEAT WG is recommended for pre-seed and pre-emergent applications. HEAT WG can also be applied in fallow crop lands and post-harvest. HEAT WG may also be used as a harvest aid in registered crops.
HEAT WG does not control grass weeds. HEAT WG should always be tank mixed with glyphosate for broad spectrum weed control.
HEAT WG is a broad spectrum weed resistance management tool for activity on a range of broadleaf weeds.

9.1.3HARVEST AID (Section 9.1.3)
HEAT WG may be used as a harvest aid to accelerate the rate of crop dry down and improve crop uniformity to facilitate direct combining. Early application may result in yield loss.
The dry down of crops will be best under favorable environmental conditions like warm temperatures, good moisture conditions and high humidity.
Harvesting of crops can be done when plant material is dry and seed moisture level allows efficient harvesting. For most crops, harvest can normally commence within 3-10 days after desiccation. Adverse weather conditions such as rainfall, cool temperatures and high humidity may slow the plant desiccation and keep seed moisture levels high which can delay commencement of harvest after the HEAT WG application.
HEAT WG when used as harvest aid will not affect the seed germination if applied according to label recommendations.
Crop - Canola, dry common beans, flax, lentils (2), mustard (1), peas (dried field), soybeans, sunflower
Use Rate (g/ha) - 36 – 71
Application Timing - Harvest aid
(1) All classes, including brown, oriental, canola quality Brassica juncea, Brassica juncea varieties with the Clearfield trait, and yellow mustard.
(2) Apply only to red lentil varieties.
Aerial Application
HEAT WG can be used for aerial application when used as a harvest aid in the registered crops.
Avoid application of this product when winds are gusty. DO NOT apply when wind speed is greater than 16 km/h at flying height at the site of application. DO NOT apply with spray droplets smaller than the American Society of Agricultural Engineers (ASAE) medium classification. To reduce drift caused by turbulent wingtip vortices, the nozzle distribution along the spray boom length MUST NOT exceed 65% of the wing- or rotorspan.
Ensure thorough coverage of foliage. Consult nozzle manufacturer’s recommendation for spray pressures for specific nozzles.
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.
Do not apply during periods of dead calm.
Observe buffer zones specified under Section 16 (Restrictions and Limitations).
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 Manual, developed by the Federal/Provincial/Territorial Committee on Pest Management and Pesticides.
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, a long-sleeved shirt, long pants, coveralls, shoes plus socks, and goggles or face shield during mixing/loading, cleanup and repair. Applicators must wear long-sleeved shirt, long pants, and shoes plus socks.

15.0 SPRAYING INSTRUCTIONS
Water volume and spray pressure
Conventional ground application
Use sprayers equipped with standard flat nozzles. The use of 80°-110° stainless steel flat fan nozzle is recommended for optimum spray coverage with nozzles tilted 45° forward to ensure better coverage.
Thoroughly clean all screens to prevent nozzle clogging. Apply in a water volume of 50-100 L/ha and at a pressure of 240 kPa. For applications to dense weed infestations and thick canopies, use a higher water volume at pressures of 275 kPa.
Better coverage of the product results in enhanced control of weeds.
16.0 RESTRICTIONS AND LIMITATIONS
1. Wash sprayer thoroughly after use to avoid damage to the next crop sprayed.
2. DO NOT mix or apply HEAT WG with any other additive, pesticide or with fertilizer except as specifically recommended on this label.
3. DO NOT APPLY BY AIR, unless specified otherwise.
4. DO NOT enter or allow worker entry into treated areas for 12 hours after application.
5. Field corn – Corn forage and silage can be harvested, used as feed or grazed 60 or more days after application of HEAT WG.
6. Legume forage (chickpeas, field peas and lentils) may be used as feed or grazed 60 or more days after application of HEAT WG. Desiccation treated pea vines may be grazed or fed to livestock.
7. Small grains (wheat, barley and oats) – forage and hay can be used as feed or grazed 30 or more days after application of HEAT WG.
8. Soybeans may be used as feed or grazed 60 or more days after application of HEAT WG.
9. Soybeans and dry common beans – Do not graze or feed treated hay or straw to livestock when HEAT WG is used as a harvest aid.
10. Bromegrass – DO NOT graze the treated area or cut for hay; sufficient data are not available to support such use.
11. DO NOT apply directly to water. DO NOT contaminate irrigation or drinking water supplies or aquatic habitats by cleaning of equipment or disposal of wastes.
12. To reduce runoff from treated areas into aquatic habitats, avoid application to areas with a moderate to steep slope, compacted soil, or clay. Avoid application when heavy rain is forecast. Contamination of aquatic areas as a result of runoff may be reduced by including a vegetative strip between the treated area and the edge of the water body.
13. As this product is not registered for the control of pests in aquatic systems, DO NOT use to control aquatic pests.
Buffer zones
Field sprayer application: DO NOT apply during periods of dead calm. Avoid application of this product when winds are gusty. DO NOT apply with spray droplets smaller than the American Society of Agricultural Engineers (ASAE) medium classification. Boom height must be 60 cm or less above the crop or ground.
Aerial application: DO NOT apply during periods of dead calm. Avoid application of this product when winds are gusty. DO NOT apply when wind speed is greater than 16 km/h at flying height at the site of application. DO NOT apply with spray droplets smaller than the American Society of Agricultural Engineers (ASAE) medium classification. To reduce drift caused by turbulent wingtip vortices, the nozzle distribution along the spray boom length MUST NOT exceed 65% of the wing- or rotorspan.
Use of the following spray methods or equipment DO NOT require a buffer zone: hand-held or backpack sprayer and spot treatment.
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).
Method of application - Field sprayer (1)
Crop – Lentils, soybean (pre-seed or pre-emergent)
Buffer zone (metres) required for the protection of Terrestrial Habitat – 3
Method of application - Field sprayer (1)
Crop – Barley, bromegrass, canary seed, chickpea, corn, oats, dried field peas, wheat (pre-seed or pre-emergent); Chemfallow; Canola, flax, lentil, mustard, soybean, dried field peas, sun
Buffer zone (metres) required for the protection of Terrestrial Habitat – 10
Method of application – Aerial (fixed wing)
Crop – Canola, flax, lentil, mustard, soybean, dried field peas, sunflower, dry common bean (harvest aid)
Buffer zone (metres) required for the protection of Terrestrial Habitat – 175
Method of application - Aerial (rotary wing)
Crop – Canola, flax, lentil, mustard, soybean, dried field peas, sunflower, dry common bean (harvest aid)
Buffer zone (metres) required for the protection of Terrestrial Habitat – 150
(1) For field sprayer application, buffer zones can be reduced with the use of drift reducing spray shields. When using a spray boom fitted with a full shield (shroud, curtain) that extends to the crop canopy, the labeled buffer zone can be reduced by 70%. When using a spray boom where individual nozzles are fitted with cone-shaped shields that are no more than 30 cm above the crop canopy, the labeled buffer zone can be reduced by 30%.
For tank mixes, consult the labels of the tank-mix partners and observe the largest (most restrictive) buffer zone of the products involved in the tank mixture and apply using the coarse spray (ASAE) category indicated on the labels for those tank mix partners.
17.0 RESISTANCE-MANAGEMENT RECOMMENDATIONS
For resistance management, HEAT WG is a Group 14 herbicide. Any weed population may contain or develop plants naturally resistant to HEAT WG and other Group 14 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 HEAT WG or other Group 14 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.
