Sharpen®

Herbicide

Fast, effective control of broadleaf weeds

ACVM Registration No.P008391

Active ingredient(s): 700 g/kg Saflufenacil
Formulation: Water dispersible granules (WG)

Sharpen® has rapidly established itself as a key herbicide to help reduce early weed competition, filling a gap in the burndown market for a flexible and efficient broadleaf herbicide to complement the grass weed specialists.

Upgrade your pre-em weed control in maize

The new FlexiRate for Sharpen now offers you the chance to maximise your ROI as you strengthen your pre-emergence weed control program.

Key benefits

  • Fast, robust control of key broadleaf weeds
  • Mix with acetochlor to control both grass & broadleaf weeds for up to 8 weeks
  • Excellent residual activity on atrazine-resistant fathen 

Sharpen up your weed control this season with added flexibility

Weeds start impacting maize yield from three weeks after emergence, so controlling weeds right from the start using the best available herbicide really pays off.

  • The economical new 100 g/ha rate offers you a significant upgrade option if you’ve been using atrazine: 100 g/ha Sharpen + acetochlor delivers 50% better control of broadleaf weeds than atrazine + acetochlor.
  • The original and standard 150 g/ha rate is an even bigger upgrade and still the best value choice for targeting high yields or managing high weed pressure, especially in heavy soils.
  • Sharpen is particularly effective on hard-to-manage broadleafs like fathen, willow weed and black nightshade.
  • Adding Sharpen’s Group 14 chemistry to the rotation opens up more post-emergence options and reinforces your resistance management.

How it works

Sharpen® is a Group 14 herbicide from the PPO (protoporphyrinogen-oxidase) mode of action group. It is rapidly absorbed through the roots and foliage of plants. Within a few hours following application, the foliage of susceptible weeds shows signs of desiccation, and in subsequent days necrosis and death. Extremes in environmental conditions (temperature and moisture), soil conditions and cultural practices may affect the activity of Sharpen. Under warm, moist conditions, herbicide symptoms may be accelerated. Under very dry conditions the expression of herbicidal symptoms is delayed, and weeds hardened off by drought are less susceptible to Sharpen.
