Spray Drift

APVMA Releases Changes to 2,4-D Chemical Use

The APVMA is implementing new instructions to mitigate the risk of spray drift, which restrict the application of 2,4-D herbicides. In order for these new instructions to be in place, all current 2,4-D labels will be cancelled and the use of 2,4-D will be through a permit. The permit will stay in place until the conclusion of the current 2,4-D review.

What you need to know

  • The full instructions can be found here https://apvma.gov.au/node/32941
  • Do not spray when a surface temperature inversion is present
  • Applicators must now use at least a Very Coarse (VC) spray quality
  • When using a boom sprayer, boom heights must be 0.5m or lower above the target canopy
  • Downwind buffers now apply (typically less than 50m, subject to rate and product being applied) between application sites, downwind sensitive crops and environmentally sensitive aquatic areas
  • Additional record keeping is required. Operators need to update spray records, with greater detail, within 24 hours of application and keep these records for a minimum of two years.

The webinar will cover

The webinar will include a presentation by APVMA about the changes and feature a panel of experts to provide practical advice and personal experience to answer your questions.

  • APVMA explanation of changes to the ‘directions for use’ for 2,4-D.
  • Changes to application techniques.
  • Spray quality.
  • Timing.
  • The observance of mandatory no-spray buffer zones.
  • Increased requirements for detailed record keeping.
  • Interactive Q&A session with an expert panel.
