How it Works

  • Solo delivers the solid weed control you need to grow a great crop.
  • It controls weeds growing at the time of application and offers exceptional follow-crop safety.

Application Tips

Rainfastness - 3 hours.
  • Avoid application immediately before or after frost or during unseasonably cold weather.
  • Treat when weeds are actively growing.
  • Use higher water volume on dense weeds and thicker canopies.

When to Apply

Solo has a wide window of application that allows you to control early-emerging weeds before they affect yield.

Crop or weed type Stage
Clearfield lentils 2 to 6 leaf stage
Clearfield sunflowers 2 to 8 leaf stage
Broadleaf weeds Cotyledon to 4 leaf stage
Grassy weeds 1 to 4 true leaf stage (6 total leaves, including 2 tillers)

How Much to Apply

One case will treat 40 acres.

Solo herbicide 11.7 g/ac (29 g/ha)
Merge® adjuvant* 0.5 v/v (e.g. 500ml per 100 L spray solution)

Water volume

Ground application only 40 L/ac (10 gal/ac)

*Merge adjuvant (required for optimum activity) is not included in the case.

Mixing Instructions

  1. Use a 50 mesh (or coarser) filter screen and fill tank 3/4 full with correct amount of water. Start and continue agitation throughout mixing and spraying.
  2. Add the required amount of Solo herbicide water-soluble bags directly into the sprayer through the tank opening and allow to dissolve completely.
  3. For Solo plus Lontrel® herbicide tank-mix, add recommended amount of Lontrel.
  4. Agitate for at least 10 minutes to dissolve the herbicide. After the herbicide is dissolved, continue agitation.
  5. If required, add the correct amount of Merge adjuvant. If excess foaming occurs, a silicone anti-foaming agent may be added (e.g. Halt®).
  6. 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.
  7. Between loads of tank-mix, check in-line and nozzle screens and rinse clean if needed.
