The safer knockdown alternative
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.
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.
