Fenceline Spraying

Overuse of glyphosate in fencelines and around the edge of crops can lead to a build up of glyphosate resistant weeds.  How do we combat this on farm?  Through integrating different herbicide groups and through correct herbicide application.

Some notes on products for fenceline spraying below:

Alliance

Amitrole Paraquat (Gramoxone)

Controls bigger weeds than Sprayseed or Gramoxone alone. Short residual (2-3 weeks).  DO NOT apply the herbicides using hand-held or knapsack application equipment.

Alliance & Simazine

Amitrole Paraquat (Gramoxone) + Simazine

Will provide longer residual control (2-3 months). Preferred low-cost mix. DO NOT apply the herbicides using hand-held or knapsack application equipment.

Alliance & URAGAN

Amitrole Paraquat (Gramoxone) + Bromacil

Will provide the longest residual control (12 months).  Do not use in channels or near trees. DO NOT apply the herbicides using hand-held or knapsack application equipment.

Gramoxone 360 Pro & Simazine

Paraquat (Gramoxone) + Simazine
