AC 299,263 120 AS

For Sale for Use in the Prairie Provinces and Peace River Area of British Columbia Only on Clearfield Wheat (1) (Wheat Varieties with the Clearfield Trait)

FOR Clearfield WHEAT (1)

(Wheat varieties with the Clearfield trait)

DIRECTIONS FOR USE (Prairie Provinces and Peace River Area of British Columbia)
AC 299,263 120 AS Herbicide Solution is a selective herbicide that can be applied as an early post-emergent treatment in Clearfield Wheat (1) varieties. Clearfield Wheat (1) varieties are tolerant of imazamox, the active ingredient in AC 299,263 120 AS Herbicide Solution. Wheat varieties that are not designated as having the Clearfield trait may be damaged or destroyed by this treatment. When AC 299,263 120 AS Herbicide Solution is applied early postemergence, absorption may occur through both the roots and foliage. Susceptible weeds stop growing and eventually die.
Apply using ground equipment only. DO NOT APPLY BY AIR.
Do not apply more than once per year.
DO NOT apply directly to aquatic habitats (such as lakes, rivers, sloughs, ponds, coulees, prairie potholes, creeks, marshes, streams, reservoirs, ditches and wetlands) and estuarine/marine habitats.
DO NOT contaminate irrigation/drinking water supplies or aquatic habitats by cleaning of equipment or disposal of wastes.
DO NOT apply during periods of dead calm or when winds are gusty.
DO NOT graze the treated crop within 14 days of application or cut for hay within 42 days of application.
Pre-harvest Interval: Wheat grain and straw can be harvested 79 days after treatment.

BUFFER ZONE
A buffer zone of 11 metres (30 metres when tank mixed with FRONTLINE Herbicide) is 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, pastures, rangelands and shrublands). For field sprayers, buffer zones can be reduced by 70% when using shrouds or 30% when using cones.
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.

BROADLEAF WEED AND GRASS CONTROL
Application should be made from the 2 to the 6 leaf stage of wheat crop and after the weeds have emerged. To control broadleaf weeds apply AC 299, 263 120 AS Herbicide Solution from the cotyledon up to the 4 leaf stage. To control grasses apply AC 299, 263 120 AS Herbicide Solution from the 1-4 true leaf stage up until early tillering. Initial crop injury may be observed after application but this is outgrown and should not affect yield. Severe crop injury will occur as a result of spray overlap. AVOID SPRAYER OVERLAP.

Apply in 50-100 L/ha of water with a NON-IONIC SURFACTANT (e.g., AGRAL 90, AG-SURF or SURF 92) at the rate of 0.25% v/v.

MIXING INSTRUCTIONS
Use 50-100 L/ha of water. Use a 50-mesh (or coarser) filter screen. Fill the spray tank with three-quarters of the required amount of clean water, start agitation and continue agitation throughout the entire mixing and spraying procedure. Add the required amount of AC 299,263 120 AS Herbicide Solution into the sprayer through the tank opening and continue agitating.
After the herbicide is thoroughly mixed, continue agitation and add the required amount of nonionic surfactant. If excess foaming occurs, a silicone anti-foaming agent may be added (e.g. HALT). Complete filling the tank to the desired level with water. If agitation is stopped for more than 5 minutes, re-suspend spray solution by full agitation prior to commencing spraying again. Between loads of AC 299, 263 120 AS Herbicide Solution, check in-line and nozzle screens and rinse and clean if necessary. Upon completion of spraying AC 299,263 120 AS Herbicide Solution, thoroughly flush tank, boom, hoses and in-line and nozzle screens with clean water to avoid possible injury to other crops.

FOLLOW CROPPING
Winter wheat can be planted 3 months after treatment (3 MAT) as a rotational crop.
Initial crop injury to non-Clearfield canola may be observed. Avoid spray overlap as yield reduction may result. The following crops may be grown safely the year following an application:
Field peas
Field corn
Canary seed
Clearfield Canola (1) (canola varieties with the Clearfield trait)
Non-Clearfield canola
Lentils
Spring wheat
Durum wheat
Spring barley
Sunflower
Tame oats
Flax
Chickpea
The following crop may be grown safely two years following an application:
Mustard (condiment type only)
There are insufficient data for other follow crops. Conduct a field bioassay (a test strip grown to maturity) the year before growing any crop other than those listed above.

RESISTANCE-MANAGEMENT RECOMMENDATIONS
For resistance management, AC 299,263 120 AS Herbicide Solution is a Group 2 herbicide.
Any weed population may contain or develop plants naturally resistant to AC 299,263 120 AS Herbicide Solution and other Group 2 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 AC 299,263 120 AS Herbicide Solution or other Group 2 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.
