A study of 15 spray operators showed a 300% to 400% difference in volumes applied to treat the same bush. In this controlled study, all the applicators followed the same label directions and operated the same equipment. The large discrepancies in spray volumes were responsible for poor control due to under-spraying or increased costs from over-spraying.

MANAGING BLACKBERRY: HERBICIDES

Herbicides at a Glance

Five considerations when selecting a herbicide:

  • Proximity of the application site to water.
  • Selectivity of herbicide.
    It is best practice in weed management to retain desirable species and maintain groundcover.
  • Cost of herbicide.
    Low-cost active ingredients will not always give the best long-term control. Application costs for retreatment need to be factored into the decision.
  • Level of control.
    Experience has shown that a mixture of triclopyr + picloram +/– aminopyralid will give the greatest long-term control.
  • Application costs.
    For large infestations the cost of retreatment is often underestimated.

 

 

Situations for specific herbicides:
Metsulfuron-methyl: Recommended for initial treatment of large, dense infestations.

 

Glyphosate: Recommended for small infestations that are easy to check and retreat and areas where other herbicides cannot be used, such as in or near watercourses and in urban and peri-urban areas.

 

Triclopyr: Recommended for initial treatment of large infestations.

 

Picloram: Recommended where the use of pellet formulations is considered the most appropriate application technique.

 

Picloram + Triclopyr: Recommended for most infestations, both large and small, as it usually provides the highest levels of control.
