Technical readiness:
Machinery for this technique is available on the Swedish market, although it is relatively expensive, and practical experience with it in Sweden remains limited.Ease and efficiency of implementation:
The method requires specialized equipment and is best combined with complementary measures such as harrowing between rows. In cases with significant black grass presence between rows, this approach can be useful for applying glyphosate precisely.Need for training and education:
Extensive education and training are required. It is crucial to avoid spraying between rows if the goal is to target only in-row areas, in order to prevent exacerbating herbicide resistance. Timing is also critical to avoid crop damage.Need for investment:
The approach involves substantial investment, particularly in high-precision components such as advanced cameras and GPS guidance systems to ensure effectiveness.
Description
This solution is designed for crops that are sown in rows with wider spacing—typically more than 12.5 cm between rows. It enables targeted herbicide application directly within the crop rows while allowing for mechanical hoeing between them, combining chemical and mechanical weed control strategies effectively.

Explanation
This method has the potential to reduce herbicide use by more than 50%, significantly lowering chemical inputs in the field. Although it requires specialized equipment, the reduction in herbicide usage makes it a valuable practice for sustainable agriculture and environmental protection.
Advantages
High potential to significantly reduce herbicide use.
No significant socio-economic effects noted.
No specific operational advantages reported.
Contributes to lower herbicide usage and reduced environmental impact.
Drawbacks
Effectiveness depends on the type of nozzles used. Manufacturer support may be required. Limited use reported in Sweden. It can be challenging to apply herbicide strictly within the inter-row space.
No significant socio-economic drawbacks identified.
Requires training. Could be incorporated into existing sprayer training programs.
No major environmental disadvantages compared to standard spraying practices.
