Active materials


SOLO ADV is a selective herbicide that can be applied as an early post-emergence treatment in 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), Clearfield Canola (1) Quality Brassica juncea (canola quality Brassica juncea varieties with the Clearfield trait), and soybeans.
When SOLO ADV is applied early post-emergence, absorption may occur through both the roots and foliage. Susceptible weeds stop growing and eventually die.
Use of SOLO ADV on canola, canola quality Brassica juncea, sunflower or lentil varieties not designated with the Clearfield trait will cause severe injury.

DO NOT apply more than once per year.

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 S572.1) medium classification. Boom height must be 60 cm or less above the crop or ground.
DO NOT apply by air.

Buffer Zones
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) and sensitive freshwater habitats (such as lakes, rivers, sloughs, ponds, prairie potholes, creeks, marshes, streams, reservoirs and wetlands).

Method of Application – Field Sprayer
Crop – All crops
Buffer Zones (metres) Required for the Protection of:
Freshwater Habitat – 11
Terrestrial Habitat – 11

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 coarsest spray (ASAE) category indicated on the labels for those tank mix partners.

Registered Crops and Application Timing
SOLO ADV may be applied as an early post-emergence treatment to the following crops. Applications should be made at the appropriate crop staging as indicated below and after weeds have emerged. To control broadleaf weeds, apply SOLO ADV from the cotyledon to the 4-leaf stage. To control grasses, apply SOLO ADV from the 1 to 4-true leaf stage up until early tillering.

The following pre-harvest and grazing intervals should be observed for respective crops.
Crop - PHI (days)
Clearfield canola (1) - 60
Clearfield Canola (1) quality Brassica juncea – 60
Clearfield lentils (1) – 60
Clearfield sunflowers (1) – 70
Soybeans – 60

DO NOT graze the treated Clearfield Canola (1), Clearfield Lentils (1), soybeans 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.

1. DO NOT apply when weather conditions may cause spray drift from treated fields to adjacent crops. Clean sprayer thoroughly after use to avoid damage to the next crop sprayed.
2. DO NOT enter or allow worker entry into treated areas during the restricted entry interval (REI) of 12 hours.
3. DO NOT contaminate irrigation or drinking water supplies or aquatic habitats by cleaning of equipment or disposal of wastes.
4. DO NOT apply to any crops that have been subjected to stress from conditions such as frost, hail damage, flooding, drought, hot, humid weather, widely fluctuating temperature conditions, prolonged cold weather or injury from prior herbicide applications, as crop injury may result.
5. Apply only when the potential for drift to areas of human habitation or areas of human activity such as houses, cottages, schools and recreational areas is minimal. Take into consideration wind speed, wind direction, temperature inversions, application equipment and sprayer settings.
6. As this product is not registered for the control of pests in aquatic systems, DO NOT use to control aquatic pests.
7. In some cases, tank mixing a pest control product with another pest control product or a fertilizer can result in biological effects that could include, but are not limited to: reduced pest efficacy or increased host crop injury. The user should contact BASF at 1-877-371-2273 or for information before mixing any pesticide or fertilizer that is not specifically recommended on this label. The user assumes the risk of losses that result from the use of tank mixes that do not appear on this label or that are not specifically recommended by BASF.

Select proper nozzle to avoid spraying fine mist. For best results, use sprayers equipped with flat fan or similar nozzles to ensure coverage. Apply in a spray volume of 100L/ha and at a pressure of 275kPa. Better coverage of the product results in enhanced control of weeds.

1. When applying SOLO ADV, always start with a clean sprayer. Refer to previously applied product labels for specific cleaning instructions.
2. Fill the clean spray tank with half to three-quarters of the required amount of clean water and start agitation system. Agitation should be running during the entire mixing procedure.
3. Add the correct amount of SOLO ADV and continue to agitate.
4. If required, add the required amount of Lontrel 360 or POAST ULTRA Liquid Emulsifiable Herbicide while agitating the spray solution.
5. Continue agitation while filling the spray tank with the remaining amount of water.
6. Maintain continuous and constant agitation throughout application until spraying is complete.
7. Upon completion of spraying SOLO ADV, thoroughly flush tank, boom, hoses and in-line and nozzle screens with clean water to avoid possible injury to other crops.

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)
Non-Clearfield canola
Spring wheat
Durum wheat
Spring barley
Tame oats
Clearfield Sunflowers (1)

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.

For resistance management, SOLO ADV 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 ADV 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.
For further information or to report suspected resistance, contact BASF at 1-877-371-2273 or at
