Active materials


HALEX GT Herbicide contains three active ingredients for a one-pass broad-spectrum weed management program in Glyphosate Tolerant corn. HALEX GT Herbicide has both contact and residual activity. Following a post-emergent application of HALEX GT Herbicide, emerged weeds take up the herbicide through treated foliage and cease growth soon after application. HALEX GT Herbicide is also absorbed through the soil and/or by the foliage of emerging weeds. Complete death of the weeds may take up to 2 weeks. HALEX GT Herbicide providesresidual control of newly emerging susceptible weeds through root and shoot absorption. HALEX GT Herbicide has a high level of crop safety in Glyphosate Tolerant corn.
Use good pesticide practices and apply only when the potential for drift to areas of human habitation or areas of human activity such as houses, cottages, schools and parks is minimal. Take into consideration wind speed, wind direction, temperature, application equipment and sprayer settings used for applications.
DO NOT apply by air.
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.

Apply HALEX GT Herbicide at 4.2 L per hectare in a spray volume of 100 - 200 L and a minimum pressure of 206 kPa (refer to the “MIXING AND SPRAYING INSTRUCTIONS” section of this label) for post-emergent weed control from the spike up to and including the 6 leaf stage of Glyphosate Tolerant corn. A non-ionic surfactant such as AGRAL® 90 at 0.2% v/v may be added.
For best results, apply HALEX GT Herbicide to actively growing weeds that are less than 15 cm in height. For protection of the corn crop’s yield potential, apply HALEX GT Herbicide before the start of the critical period of weed control.
When Glyphosate Tolerant corn is grown under no-till conditions, a burndown weed control application may still be required prior to a HALEX GT Herbicide application.

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), sensitive freshwater habitats (such as lakes, rivers, sloughs, ponds, prairie potholes, creeks, marshes, streams, reservoirs and wetlands) and estuarine/marine habitats.
Method of application - field sprayer (1).
Crop - Glyphosate Tolerant Corn
Aquatic habitat – 25
Terrestrial habitat – 15
(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 labelled 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 labelled buffer zone can be reduced by 30%.

HALEX GT Herbicide can only be used postemergent on Glyphosate Tolerant corn.
Although HALEX GT Herbicide has a flexible recropping profile, certain crops may be sensitive to low concentrations in the soil. Therefore, careful consideration should be given to crop rotation plans prior to using HALEX GT Herbicide (refer to "RECROPPING GUIDELINES").
Do not apply when weather conditions may cause drift to non-target areas. Severe damage or destruction may be caused by contact of HALEX GT Herbicide to any vegetation (including leaves, green stems, exposed non-woody roots, or fruit) or crops, trees, and other desirable plants to which treatment is not intended. To avoid spray drift, do not apply when wind speed is greater than 16 kph or during periods of temperature inversions. Use of larger droplet sizes will also reduce spray drift.
When weeds are stressed due to drought, heat, lack of fertility, flooding or prolonged cool temperatures, control can be reduced or delayed since the weeds are not actively growing. Weed escapes or re-growth may occur when application is made under prolonged stress conditions. Optimum weed control will be obtained if an application of HALEX GT Herbicide is made following label directions when weeds are actively growing. If an activating rain (12 mm) is not received within 7-10 days after a postemergent application, residual weed control will be reduced.
Thorough coverage of emerged weeds is essential for effective control with HALEX GT Herbicide. Although weed competition is quickly halted, visual symptoms of dying weeds (discolouration) may take up to 2 weeks to appear depending on the weed species and growing conditions.
Temporary crop injury (bleaching) may occur under extreme weather conditions or when the crop is under stress due to inadequate or abnormally high moisture levels or extreme temperatures. The symptoms are most visible where excessive rates have been applied, such as sprayer overlaps. Corn quickly outgrows these effects and continues to grow normally.
Do not make a foliar postemergent application of any organophosphate or carbamate insecticide within 7 days before or 7 days after a HALEX GT Herbicide application or severe corn injury in yield loss may occur. Do not apply HALEX GT Herbicide in a tank mix with any organophosphate or carbamate insecticide or severe corn injury in yield loss may occur.
Severe corn injury resulting in yield loss may occur if HALEX GT Herbicide is applied to corn crops that are treated with Lorsban or other organophosphate containing soil insecticides.
HALEX GT Herbicide may be applied prior to or following a pyrethroid-type insecticide such as FORCE Insecticide or MATADOR 120EC Insecticide.
Do not apply to soils that contain less than 1% or more than 10% organic matter.
Do not cultivate corn within 7 days before or after a postemergent HALEX GT Herbicide application.
Make only one application of HALEX GT Herbicide per year. Do not apply HALEX GT Herbicide to ground that has been or will be treated with CALLISTO 480SC Herbicide.
Do not apply HALEX GT Herbicide with suspension fertilizers or urea ammonium nitrate (UAN) as the carrier.

The use of urea ammonium nitrate (UAN) will result in crop injury and reduced grass weed control and is not recommended with HALEX GT Herbicide.
Water Volume:
Apply in 100 – 200 litres per hectare. When weed foliage is dense, use a minimum 140 litres per hectare.
Spray Pressure:
206 – 300 kPa
Spray Nozzles:
Flat Fan with 50 mesh or larger screens. For uniform coverage and increased penetration of the crop canopy, set the nozzles at a downward angle of 90 degrees (90).
Postemergent applications of HALEX GT Herbicide may be applied with a non-ionic surfactant such as AGRAL 90 at 0.2% v/v (2.0 L for each 1000 L of spray mixture).

Mixing Procedure:
1. Ensure that the sprayer is totally clean.
2. Fill the sprayer half full with water. Engage gentle agitation.
3. Ensure that the agitation system is working properly and that it creates a rippling or rolling action on the water surface.
4. Add the non-ionic surfactant if applicable (e.g., AGRAL 90) at 0.2% v/v.
5. Add HALEX GT Herbicide and AATREX Liquid 480 Herbicide (if an applicable tank-mix) slowly and agitate until completely dispersed. To ensure complete dispersion, wait 2 or 3 minutes after the last of the herbicide has been added to the tank.
6. Continue agitation while completing the filling of the sprayer with water.
7. Always ensure that agitation is maintained until spraying is completed, even if stopped for brief periods of time.
8. If agitation is stopped for more than 5 minutes, re-suspend the spray solution by running on full agitation prior to spraying. HALEX GT Herbicide must be sprayed the same day as mixing.
9. Do not mix, load or clean spray equipment where there is a potential to contaminate wells or aquatic systems.

To avoid subsequent injury to other crops, thoroughly clean application equipment immediately after spraying. Ensure that all traces of the product are removed. The following procedures are recommended:
1. Drain and flush tank, boom and all hoses for several minutes with clean water containing a household detergent. Do not clean the sprayer near desirable vegetation, wells or other water sources.
2. Fill the sprayer tank with clean water and add one litre of household ammonia (containing 3% ammonia) per 100 litres of water. Allow the solution to agitate for 15 minutes prior to flushing the solution through the boom and nozzles. Drain the system.
3. Remove the nozzles and screens and wash separately in a bucket containing the ammonia solution.
4. Thoroughly rinse the tank, hoses, booms, nozzles and screens with clean water for a minimum of 5 minutes to remove all traces of ammonia.
5. Dispose of all rinsings in accordance with provincial regulations.

Spray solutions of HALEX GT Herbicide should be mixed, stored and applied only in stainless steel, fibreglass, plastic and plastic-lined steel containers.
DO NOT MIX, STORE OR APPLY HALEX GT HERBICIDE OR SPRAY SOLUTIONS OF HALEX GT HERBICIDE IN GALVANIZED STEEL OR UNLINED STEEL (EXCEPT STAINLESS STEEL) CONTAINERS OR SPRAY TANKS. HALEX GT Herbicide or spray solutions of HALEX GT Herbicide react with such containers and tanks to produce hydrogen gas, which may form a highly combustible gas mixture. This gas mixture could flash or explode, causing serious personal injury, if ignited by open flame, spark, welder's torch, lighted cigarette or other ignition source.
DO NOT apply more than 4.2 L product/ha per season.
For tank mixes, consult the label(s) of the tank mix partner(s), and observe the largest (most restrictive) buffer zone of the products involved in the tank mixture.

For resistance management, HALEX GT Herbicide is a Group 9, 15 and 27 herbicide. Any weed population may contain or develop plants naturally resistant to HALEX GT Herbicide and other Group 9 and/or 15 and/or 27 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 HALEX GT Herbicide or other Group 9, 15 and 27 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.

Certain crops have been shown to be sensitive to low residues of HALEX GT Herbicide in the soil. The minimum recropping interval is the time between the last application of HALEX GT Herbicide and the anticipated date of planting of the next crop.
To avoid injury to subsequent crops after an application at the recommended rate of HALEX GT Herbicide, the following recropping intervals should be observed.
Crop – minimal recropping interval:
Winter wheat - 4.5 months
Spring wheat - 10 months
Alfalfa, potato, soybeans, transplanted tomato, white beans - 11 months
All other crops - Bioassay
Observe the recropping guidelines of any product(s) to be tank mixed with HALEX GT Herbicide.
In the event of crop failure, only field corn (grain or silage), seed corn, or sweet corn can be planted as a salvage crop in the same fields in which the failed crop was treated with HALEX GT Herbicide. An application of HALEX GT must NOT be made to the salvage crop.
Land treated with HALEX GT HERBICIDE CAN ONLY BE PLANTED TO A CROP NOT LISTED IN THE PREVIOUS TABLE if a field bioassay can be successfully performed. The bioassay must indicate normal growth with no yield reductions.
A bioassay may be conducted in any year following the year of application to assess the tolerance of the tested crop intended for planting in the year following the bioassay. Do not conduct a bioassay in the year of application. When conducting a field bioassay, it is very important to select a representative area(s) of the field previously treated with HALEX GT Herbicide to plant the test crop(s).
