Katana is a powerful, non-selective residual broad spectrum herbicide, for the control of annual and perennial weeds on natural surfaces not intended to bear vegetation and permeable surfaces overlying soil.

Katana is formulated as a water dispersible granule that is long-lasting and is effective at low dose rates. It is an excellent cost-saving option as one application of Katana can save repeated strimming visits to the same sites to tidy around obstacles and fence lines, reducing both cost and operator exposure to risks such as hand/arm vibration.

If weeds are already present, tank-mix Katana with a suitable contact herbicide such as glyphosate and apply when the weeds are actively growing.

Key points:

  • Gives long term control - for up to 5 months
  • Combines contact & residual action
  • Pre-emergent weed control
  • Early post-emergent weed control
  • Can be tank-mixed with glyphosate
  • Low dose rate

When to use

Katana can be used at any time of the year but for best results apply in early spring before the weeds germinate. If weeds are already present, tank-mix with a suitable contact herbicide such as glyphosate, when the weeds are small and actively growing.

Total Weed Control

Katana has a broad spectrum of activity. It provides initial knock-down and residual control of broad-leaved weeds and grasses. Katana does not move once in the soil profile, therefore it is especially effective for producing clearly defined edging along fence lines etc.
