Product details
Othello provides post-emergence control of meadow-grass and range of broad-leaved weeds in winter wheat crops. It contains mesosulfuron, iodosulfuron and diflufenican which give it a wide spectrum of activity.
Othello is approved for use at 1 L/ha from post-emergence until GS31 of the crop. It is usually used in spring to control meadow-grass and broad-leaved weed populations in crops that were not treated with a pre-emergence product. Susceptibility of weeds varies by growth stage so check the label carefully to time application correctly. Annual and rough-stalked meadow-grass are susceptible until GS23 of the weed.
Othello is foliar acting so application should be as a fine-medium spray so that it can land and dry on the leaves of weeds allowing the active substances to be taken in. Apply in 100-300 L/ha water with 1 L/ha biopower. Like other post-emergence products, active growth and drying time are critical for success. Target weeds must be actively growing when you make the application so that the active substances are taken in. Drying time is also important so that the herbicides isn't washed off the leaf by rain or dew. Aim to have at least 2 hours drying time after application but the longer the better particularly in cool or overcast weather when drying is likely to be protracted.
Othello has activity against other grass-weeds but the dose is not strong enough for sufficient control. Use Atlantis Star or Pacifica Plus to target black-grass, ryegrass and brome.
At 1l/ha Othello controls chickweed, mayweeds, common field speedwell, field pansy, common poppy, groundsel, red deadnettle, shepherd’s purse, charlock and volunteer oilseed rape. Also, cleavers are moderately susceptible. See the label for specific details on growth stages and susceptibility.
