Sharpen®
Sharpen up your spray program all year round
Mode of action: Group G herbicide
Active ingredient(s): 700 g/kg Saflufenacil
Formulation: Water dispersible granules
Sharpen is a powerful knockdown herbicide that can be used to replace or reinforce the effectiveness of glyphosate in different use patterns all year round.
Fast pre-sowing knockdown of broadleaf weeds, including hard-to-kill species like fleabane, sowthistle (milk thistle) and prickly lettuce. Enormous reductions in the amount of seed set by wild radish and 6 other broadleaf weeds in winter cereal crops before harvest.
Rapid and thorough desiccation of chickpeas and other pulse crops to streamline harvesting. Excellent fallow establishment and maintenance through fast knockdown of 32 broadleaf weeds. Efficient ‘winter cleaning’ of established lucerne. Clean-up of broadleaf weeds in established almond, citrus and pome orchards and around farm buildings.

Key benefits
- Targeted problem-solving from fallow to harvest
- Reduces the reliance on glyphosate
- Streamline harvesting with rapid desiccation of pulse crops
How it works
Sharpen® is a fast-acting contact herbicide and helps control weeds through a process of membrane disruption. The foliar uptake of Sharpen is rapid and plant desiccation can occur within 4 days of application. Application should target small, actively growing weeds. Subsequent germinations will not be controlled.
In most situations, Sharpen should be applied with a conventional boom sprayer with mechanical or bypass agitation in 80–250 L/ha water. Use higher water volumes if the weed infestation is dense or as weeds increase in size. Refer to label for further details.

Sharpen Knockdown
Fast broadleaf weed control prior to sowing certain grain crops and pastures, in fallow and in established lucerne crops.
Rate: 17–34 g/ha + 1% v/v high quality MSO. Refer to label for recommended use rates for targeted weeds. Most broadleaf weeds can be controlled at 17–26 g/ha, but more hard-to-control and older weeds should be treated at 26–34 g/ha.
Timing: Application should be made to small, actively growing weeds. Best control is achieved when weeds are exposed and are not shielded by other weeds and/or stubble. Problem broadleaf weeds that have germinated are easiest to control while in the small rosette growth stage. Refer to the label for ideal weed size targets.- Sharpen's unique systemic activity reduces regrowth.
- The only Group 14 (formerly Group G) herbicide that provides standalone control of 32 broadleaf weeds, reducing the dependency on glyphosate.
- Tank-mixes with either glyphosate or paraquat control an additional 14 grass and broadleaf weeds.
- Suitable for spraying in drift-sensitive areas such as near broadleaf crops (e.g. cotton) because of its low volatility.
- Mixing Sharpen with glyphosate or paraquat helps to achieve higher levels of weed control and ultimately helps reduce the weed seed bank.

Sharpen Weed Seed Set
Earlier and more effective seed-set reduction in cereals
Rate: 34 g/ha + 1% v/v Hasten or another high quality MSO.
Timing:Apply from GS71 to GS83 and at least 14 days before harvest.- Sharpen makes managing wild radish in the lead-up to harvest easier. Apply it early to protect cereal yields and set up next season. Using Sharpen to manage wild radish in the lead-up to harvest this season will help to reduce the weed burden in next year's crop.
- Optimal, uniquely early application window to minimise weed seed-set and protect crop yield
- Up to 90% reduction of viable wild radish seeds with negligible crop impact when applied from GS71
- Proven pay-off in the following season
Sharpen is the only herbicide that can be applied in wheat, barley and triticale from the watery ripe crop growth stage (GS71) to reduce wild radish seed-set.
Its high level of crop safety allows it to be applied in this very effective earlier application window prior to harvest than any of the other options for this use pattern. -
Sharpen as a Harvest Aid
Increase harvest efficiency and the value of the crop
Rate: 34 g/ha + glyphosate or paraquat at label rates + 1% Hasten or other high quality MSO
Timing: Apply once seeds reach full physiological maturity and at least 7 days before harvest.- Use Sharpen as a harvest aid in pulse crops to provide:
- Upgraded grain quality and storability through rapid, thorough desiccation
- Rapid burndown of key broadleaf weeds and reduction of green trash
- Improved harvest efficiency
-
Sharpen in Lucerne
Grow clearer, more productive lucerne & pasture
Rate: 17-34 g/ha plus 1% Hasten or high quality MSO.
The registration of Sharpen Herbicide for broadleaf weed control in lucerne provides a much needed option for growers. It broadens BASF's product offer to lucerne producers with Spinnaker and Raptor herbicides already utilised for weed control across Australia.
Sharpen can only be used in established lucerne, at least 12 months old. For optimal coverage and control, apply after grazing or hay cut.
Sharpen can be used up to 1 hour before sowing sub clover based pastures for rapid and robust control. Tank-mixes with paraquat or glyphosate extend the control spectrum to 46 broadleaf and grass weeds.
