How it Works

Odyssey Ultra uses three active ingredients comprising two modes of action for proven grassy weed control. It also delivers control of tough broadleaf weeds, including extended control of flushing weeds. Its multiple modes of action help with resistance management.

Application Tips

Rainfastness - 3 hours after application.

Apply in warm weather to weeds that are actively growing.

Avoid applying immediately after or preceding a frost or unseasonably cold weather.

When to Apply

Apply early post emergence in Clearfield® canola, Clearfield lentils, faba beans, field peas and soybeans. The crop stages for application are

Crops Staging
Clearfield canola 2 to 6 leaf stage
Clearfield lentils 1 to 9 node stage
Faba beans 1 to 6 leaf
Field peas 1 to 6 true leaf
Soybeans 1 to 3 true leaf stage

Apply when broadleaf weeds are from the cotyledon to 4 leaf stage and when grassy weeds are at the 1 to 6 true leaf stage or up to 2 tillers (except where indicated).

How Much to Apply

Odyssey Ultra is a tank-mix that contains two components: Odyssey Ultra A and Odyssey Ultra B

One case will treat 40 acres.

Odyssey Ultra (A) 17 g/ac (43 g/ha)
Odyssey Ultra (B) 154 ml/ac (380 ml/ha)*
Merge® adjuvant** 0.5% v/v (e.g. 500 ml per 100 L spray solution)

Water volume

Ground application only 20 to 40 L/ac (5 to 10 gal/ac)

* For control of fall emerged Japanese brome grass, add Poast® Ultra herbicide (at 90 ml/ha) to the tank mix. See label for details.
** Merge adjuvant is required and is included with Odyssey Ultra case.

Mixing order
  1. Use a 50 mesh (or coarser) filter screen and fill the spray tank 3/4 full with the correct amount of water.
  2. Add the required amount of Odyssey Ultra A herbicide water-soluble bags directly into the sprayer through the tank opening. Agitate for at least 10 minutes to dissolve the herbicide.
  3. After the herbicide is dissolved, use a separate calibrated measuring device to add the required amount of Odyssey Ultra B herbicide while agitating the spray solution.
  4. Continue agitation while adding the required amount of Merge adjuvant. If excess foaming occurs, a silicone anti-foaming agent may be added (e.g. Halt®).
  5. 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.
  6. Between loads of tank mix, check in-line and nozzle screens and rinse clean if needed.
