Robotic weeder radically reduces herbicide use and increases yields

Adigo’s autonomous weeding robot for precision farming, Asterix, aims herbicide droplets directly at weeds without hitting the crop or soil.

Herbicides are key to profitability in conventional farming. However, excessive use of herbicides has substantial health and environmental impacts. Residues are often found in crops, soil and waterways, posing a serious risk for agricultural workers and society at large.

Vegetable fields are typically blanket-sprayed four to six times per season, and many weeds develop herbicide resistance.

Significant reduction of herbicides

Asterix promotes sustainable agriculture through more efficient, healthier and higher-quality food production. Reducing herbicide usage by 95 per cent, Asterix is the most precise and efficient autonomous weeding robot available. First, a machine vision system maps its way by identifying the shape and position of every weed and crop. Then the patented nozzle matrix aims individual droplets of herbicide at the weed leaves without touching the crop or soil. The nozzle even hits weeds entangled in the crop, enabling the use of novel weeding agents for herbicide-sensitive vegetable crops.

For farmers facing the problem of herbicide-resistant weeds, Asterix enables the use of other conventional or environmentally safe weeding agents such as vinegar and concentrated fertiliser. Asterix is also suitable for organic farms.

Concrete benefits

Asterix increases crop yields as it aims the herbicide directly on weeds without exposing the crops. It potentially increases the value of a harvest as it produces higher quality food without herbicide residue. It is currently the only solution for intra-row weeding in sowed cultures. Moreover, it improves working conditions and reduces occupational and public exposure to herbicides and associated health hazards.

Market potential

The world population is expected to grow to 9.7 billion by 2050, a 32 per cent increase from 2015. To meet the demand for food, production will need to increase by some 25 to 75 per cent above current levels. With a reduced rural labour force and a limited amount of arable land, the development of new farming methods is imperative.

Precision farming can be used to step up food production and quality, while reducing herbicide use, cost and environmental impact. The emerging global market for robotic technology in agriculture was some USD 3.5 billion in 2016. It is expected to become one of the largest markets for robots in the world, reaching roughly USD 70 billion by 2024.

Adigo’s solution will be commercially available in 2020.
