Bolero should be surface-applied at the rate of 4 pints per acre. The field must immediately be flooded then kept either saturated or flooded continuously after the Ordram or Bolero has been applied.
Aquatic weeds are likely to be a problem in water seeded rice .
Aquatic weeds are more likely to be a problem when there is a delay in seeding after seedbed preparation and after the field has been flooded. When the field has a history of aquatic weeds, Bolero should be surface-applied before flooding prior to seeding. Londax will control ducksalad, eclipta, ammania, gooseweed, false pimpernel, water hyssop and flatsedge. Apply a labelled copper sulfate material promptly when algae shows up. Rice water weevil is a serious threat to water seeded rice.
