Buster®

Herbicide

The safer knockdown alternative

ACVM Registration No.P003064

Buster® is a versatile non-selective knockdown herbicide registered for the control of over 60 weed species in grapevines and other fruit and berry crops. Buster is also registered for the preparation of stale seedbeds, particularly where clover is a problem weed, and for general weed control.

Buster has a partially systemic mode of action that provides a higher level of crop safety than systemic alternatives like glyphosate, while also offering more robust control than purely contact herbicides such as paraquat and diquat.

Key benefits

  • Rapid and robust knockdown control of over 60 weed species 
  • A higher level of crop safety than glyphosate, especially for young trees and vines 
  • Fast-acting (visible impact within 3 days, knockdown in 7–10 days)
  • Superior performance on some weeds resistant to glyphosate

How it works

The active ingredient in Buster® is glufosinate-ammonium, a Group H herbicide which works by inhibiting the enzyme glutamine synthetase. Lack of glutamine synthetase leads to plant death through multiple disruptions of the plant metabolism, including the breakdown of photosynthesis.

Despite the absence of visual symptoms, the treated plants stop growing within the first day after application of Buster. Complete death of the weeds usually occurs between one and two weeks after treatment.
