Bayer: Approval for post-emergence application and wider labels for Proclus and Bandur
Farmers now have the option to apply Proclus® (aclonifen) or Bandur® (aclonifen) at 0.4l/ha in winter wheat and winter barley post-emergence up to the 4-leaf stage. Since approval in 2020, these herbicides were only permitted for application pre-emergence.
"This gives farmers more flexibility in how they use these herbicides in the programme," says Bayer Technical Specialist Jamie Oakley. "Current data shows that splitting the dose out can help improve longevity of protection without compromising initial weed control."
The maximum total dose of Proclus or Bandur per season is 1.4l/ha. In wheat, you can apply this in one go at pre-em. or split it out; 1l/ha at pre-em. followed by 0.4 l/ha post-em. In barley, 1l/ha is the maximum dose at pre-em. but it can now be followed up with 0.4 l/ha at post-em. to deal with difficult weed populations. If you haven't used either product at pre-em. you can still apply 0.4l/ha as part of the tank-mix for the follow up application.
"It adds something to the tank mix for the follow up application which is becoming increasingly important for weed control. We are gathering more data from trials this season to learn how to maximise the benefit of Proclus and Bandur in the programme." Increased broadleaf weed control may be one advantage of post-em. application. Aclonifen has good innate activity against many broad leaf weeds, but they tend to emerge a little later than the typical pre-em. timing.
Both herbicides now have a wider label too which includes winter beans. "This is all about simplifying things for farmers and store managers, so it is easier to plan and use herbicides in the field. Winter beans is a good example where Proclus or Bandur could be deployed in cereals and beans in the same autumn."
