Brome control planning autumn

Use as many cultural methods as possible to reduce grass-weed numbers prior to crop establishment

Managing Weeds - 2010 Brome Control Planning - Autumn

Choose the right pre-emergence herbicide for your grassweed populations

  • Know your grass-weed spectrum and resistance status
  • Trials have shown that Liberator can provide useful activity against bromes when used as an overall brome control strategy incorporating both chemical and cultural control methods.
  • Use Liberator® at 0.6 L/ha as a pre-emergence in any grass-weed situation

Recommendations for pre-em grass-weed control

Key pre-em. grass-weed spray
(within 48 hours of drilling)

Pre-em. tank-mix options
(can offer extra brome control)

Liberator

0.6 L/ha

+ Prosulfocarb 1600g a.s./ha
(winter wheat pre-em. only)

 

+ Pendimethalin up to 1200g a.s./ha

 

+ Diflufenican (DFF®) up to an additional 60g a.s./ha
• can also give extra BLW control

 

+ Chlorotoluron (CTU) up to 2100g a.s./ha
• CTU tolerant varieties only
• needs at least 6 weeks before Atlantis® WG follow up

Apply the pre-emergence herbicide as a true pre-emergence application

  • Liberator works best as a true pre-emergence herbicide
  • Aim to apply within 48 hours of drilling. DO NOT be tempted to wait for moisture to be present before spraying
  • The best pre-emergence performances are from full rates on a fine, firm, consolidated seedbed within 48 hours of drilling
