Duration 

3 years  

How much you’ll be paid  

£43 per hectare (ha) per year  

Action’s aim  

This action’s aim is that camera or remote sensing guided technology is used to apply systemic herbicides to control weeds, so they’re targeted precisely.  

The purpose of this is to:  

  • reduce the volume of herbicide applied 

  • increase biodiversity 

  • improve water quality, soil quality and productivity 

  • support an integrated pest management approach 

Where you can do this action  

You can do this action on agricultural land located below the moorland line that’s:  

  • receiving systemic herbicides to control weeds which camera or remote sensing guided technology can recognise 

  • an eligible land type (as defined in section 5.1.1 ‘Eligible land types’ in the SFI26 scheme information) 

  • registered with an eligible land cover on your digital maps 

  • declared with a land use code which is compatible with the land cover 

Camera recognition is currently available for:   

  • docks and nettles in grass or leys containing clover 

  • all weeds in maize 

  • certain crops grown on wide row spacings (such as potatoes) 

  • stubbles – where there’s green growth 

Remote sensing technology uses artificial intelligence to recognise target weeds.  

Eligible land 

Eligible land type Eligible land cover Compatible land use code
Arable land used to grow crops Arable land Land use codes for arable crops or leguminous and nitrogen-fixing crops  
Temporary grassland Arable land TG01  
Arable land lying fallow Arable land FA01  
Permanent grassland – improved and low input Permanent grassland PG01  
Permanent crops Permanent crops Land use codes for permanent crops  

Eligibility of protected land 

Sites of special scientific interest (SSSIs): Eligible – you must: 

Historic and archaeological features: Eligible – you must get an SFI HEFER before you do this action (read section 5.3 ‘Land with historic or archaeological features’ in the SFI26 scheme information to find out how to do this). 

Available area you can enter into this action 

Total or part of the available area in a land parcel. It’s your responsibility to check that the area you enter is eligible for this action. 

You must do this action on the area entered into your SFI26 agreement. If something happens which means you cannot complete this action on some or all of the area, you must tell the RPA in writing as soon as possible. Read section 12.2 ‘What to do if you cannot comply with your agreement’ in the SFI26 scheme information to find out how to do this.        

Rotational or static action  

This action is rotational or static. This means you can either:  

  • move its location for the second and third years of this action’s duration 

  • do it at the same location each year of this action’s duration 

What to do 

You must apply systemic (contact) herbicides on land entered into this action using camera or remote sensing technology that:  

  • identifies specific weeds to be controlled 

  • automatically switches on individual nozzles to apply the herbicides directly to the identified weeds 

Systemic herbicides kill the whole weed, from leaf to root.  

You must only carry out a ‘blanket’ application of herbicides if you’re applying:  

  • glyphosate to destroy a cover crop or create a stale seedbed before drilling 

  • residual herbicides before sown crop plants or weeds emerge (‘pre-emergence’) – this can be at the same time the crop is established (drilled or planted) or within a few days of establishment 

  • pre-harvest herbicide or desiccant to combinable crops 

A ‘blanket’ application means you apply herbicides uniformly across an area, rather than targeting the application to identified weeds.  

When to do it  

You must do this action from its start date, throughout each year of its 3-year duration.   

How to do it  

You must follow this action’s requirements – these are identified by a ‘must.’  

You may find it helpful to read the ‘advice to help you do this action’, but it’s not part of this action’s requirements. 

Evidence to keep  

You must keep evidence to show what you’ve done to complete this action, such as:   

  • ‘as applied’ data, such as a map showing where individual nozzles switch on to apply herbicide 

  • a record of any permitted blanket application of herbicide, including the date it was applied 

  • contractor’s invoice if you use a contractor to do this action 

If it’s not clear that you’ve done this action in a way that could reasonably be expected to achieve its aim, we may ask for this evidence. You must supply the evidence if we ask for it.  

Other actions or options you can do on the same area as this action  

You can do the following actions or options on the same area in a land parcel as this action.

  1. Added 'Advice to help you do this action' section.

  2. No substantive changes have been made to this action for SFI26 (compared with the SFI24 version). There have only been minor updates to standard wording which appears in all area-based SFI actions. See ‘Eligibility of protected land’ and ‘Available area you can enter into this action’.

  3. Where you can do this action - an eligible land type is defined in section 5.1 ‘Eligible land types for SFI’ in the SFI scheme information. Eligibility of protected land - updated link to section 10.3 ‘SSSI consent’ in the SFI scheme information. What to do - you can carry out a ‘blanket’ application of herbicides if you’re applying residual herbicides before sown crop plants or weeds emerge (‘pre-emergence’). This can be at the same time the crop is established (drilled or planted) or within a few days of establishment. Published voluntary advice to help you do this action, but it's not part of this action’s requirements.
