Bayer is reminding growers about the benefits of a well-timed application of Atlantis-WG (mesosulfuron + iodosulfuron) for black-grass control with two short animated films that look at the role Atlantis WG continues to play in weed control programmes.
“We realise that, for some farmers, Atlantis WG doesn’t give the same level of black-grass control as when it first came out but it still delivers valuable activity within a programme,” says Bayer Campaign Manager Phillippa Overson.
“The post-em spray is the last stage in a programme of cultural and chemical techniques that should push overall control past the critical 95% barrier.”
Bonfire night has traditionally been the date for post-em sprays; but with many people drilling later – spring application is now very common.
“We’ve found that what really matters is the growth stage of the black-grass, not the calendar date. The main thing is to apply before the black-grass starts tillering because smaller plants are less able to deal with the herbicide.”
Liberator (flufenacet + diflufenican) at 0.3L/Ha can also be included as part of a tank mix to mop up any late germinating weeds. But growers are advised that there must be a six-week gap from a pre-emergence application of Liberator and it cannot be applied to crops after GS22.
