FOR SALE FOR USE IN THE PRAIRIE PROVINCES AND PEACE RIVER AREA OF BRITISH COLUMBIA ONLY

Clearfield Canola (1) (canola varieties with the Clearfield trait), Clearfield Lentils (1) (lentil varieties with the Clearfield trait), Clearfield Sunflowers (1) (sunflower varieties with the Clearfield trait) and Clearfield Canola (1) Quality Brassica juncea (canola quality Brassica juncea varieties with the Clearfield trait)


DIRECTIONS FOR USE (Prairie Provinces and Peace River Area of British Columbia only)
SOLO WDG Herbicide is a selective herbicide that can be applied as an early post-emergence treatment in Clearfield Canola (1), Clearfield Lentils (1) and Clearfield Canola (1) Quality Brassica Juncea.
When SOLO WDG herbicide is applied early post-emergence, 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 graze the treated Clearfield Canola (1), C learfield Lentils (1) or Clearfield Canola (1) quality Brassica juncea or cut for hay within 20 days of application.
DO NOT graze treated sunflower plants or cut for straw; sufficient data are not available to support such use.
Pre-harvest Interval: After 60 days, canola, Clearfield Lentils (1) and Clearfield Canola (1) Quality Brassica juncea can be harvested. Sunflowers can be harvested after 70 days.
Overspray or drift to sensitive habitats should be avoided. A buffer zone of 11 metres is required between the downwind point of direct application and the closest edge of (1) sensitive terrestrial habitats (such as grasslands, forested areas, shelter belts, woodlots, hedgerows, pastures, rangelands, and shrublands), (2) sensitive aquatic habitats (such as lakes, rivers, sloughs, ponds, coulees, prairie potholes, creeks, marshes, streams, reservoirs, and wetlands) and (3) estuarine or marine habitats.
DO NOT apply during periods of dead calm or when winds are gusty.
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.
DO NOT apply this product directly to freshwater habitats (such as lakes, rivers, sloughs, ponds, coulees, prairie potholes, creeks, marshes, streams, reservoirs, ditches and wetlands), estuaries or marine habitats.
DO NOT contaminate irrigation or drinking water supplies or aquatic habitats by cleaning of equipment or disposal of wastes.

Application should be from the 2 to 6 true leaf stage of the crop and after the weeds have emerged. To control broadleaf weeds, apply SOLO WDG herbicide from the cotyledon to the 4-leaf stage. To control grasses, apply SOLO WDG herbicide from the 1 to 4 true leaf stage until early tillering. Initial transient crop yellowing may be observed after application but this is outgrown and should not affect yield.

Clearfield Sunflowers (1) (sunflower varieties with the Clearfield trait)
Application should be made from the 2 to 8 leaf stage of the sunflower crop and after the weeds have emerged. To control broadleaf weeds, apply SOLO WDG herbicide from the cotyledon up to the 4-leaf stage. To control grasses, apply SOLO WDG herbicide from the 1 to 4-true leaf stage up until early tillering. Initial transient crop yellowing may be observed after application but this is outgrown and should not affect yield.
Apply in 100 L/ha of water with MERGE Adjuvant at a rate of 0.5% v/v (e.g. 5 L of MERGE Adjuvant per 1000 L spray solution).

Clearfield Lentils (1) (lentil varieties with the Clearfield trait)
Application should be made from the 2 to 6 leaf stage of the lentil crop and after the weeds have emerged. To control broadleaf weeds, apply SOLO WDG herbicide from the cotyledon up to the 4-leaf stage. To control grasses, apply SOLO WDG herbicide from the 1 to 4-true leaf stage up until early tillering.

Tank Mix Rotational Crop Restrictions
SOLO WDG Herbicide + Lontrel Dry Soluble Granular Herbicide in Clearfield Canola (1) (canola varieties with the Clearfield trait)
Fields previously treated with tank mix can be seeded to wheat, barley, oats and rye (not under-seeded to forage legumes, clover or alfalfa), canola, corn, field peas, flax, forage grasses or can be summer-fallowed. Seed only those crops listed above in the year following treatment.
Do not seed to field peas for at least 10 months following treatment. Very dry soil conditions following application can result in a risk of injury to field peas grown in rotation. If severe drought conditions are experienced during the months of June to August inclusive in the year of application, delay seeding field peas an additional 12 months (total 22 months following application).
Contact your local BASF Canada representative or retailer for more information before seeding field peas following drought conditions in the previous year.

Tank Mix Pre-harvest / Grazing Interval
Do not harvest the treated crop within 60 days of application.


MIXING INSTRUCTIONS
1. Use 100 L/ha of water.
2. Use a 50-mesh (or coarser) filter screen.
3. 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.
4. Add the required amount of SOLO WDG herbicide soluble bag(s) directly into the sprayer through the tank opening.
5. For SOLO WDG Herbicide + Lontrel Dry soluble granular herbicide tank mix, add recommended Lontrel Dry soluble granular herbicide.
6. Agitate for at least ten minutes to dissolve the herbicide. After the herbicide is dissolved, continue agitation.
7. If required, add the required amount of MERGE Adjuvant. If excess foaming occurs, a silicone anti-foaming agent may be added (e.g. HALT).
8. 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.
9. Between loads of SOLO WDG Herbicide and Lontrel Dry soluble granular herbicide, check in-line and nozzle screens and rinse clean if necessary.
10. Upon completion of spraying SOLO WDG herbicide or the tank mix, 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:
Canary seed
Field corn
Field peas
Clearfield Canola (1) (canola varieties with the Clearfield trait)
Non-Clearfield canola
Lentils
Spring wheat
Durum wheat
Spring barley
Sunflower
Tame oats
Flax
Chickpeas
Clearfield Sunflowers (1)(sunflower varieties with the Clearfield trait)

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, SOLO WDG herbicide is a Group 2 herbicide. Any weed population may contain or develop plants naturally resistant to SOLO WDG herbicide 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 SOLO WDG herbicide or other Group 2 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.
