Onions including volunteer potatoes
Onion crops are moderately sensitive to chemicals and have a sparse canopy that leaves much of the soil uncovered, creating ideal conditions for aggressive weed growth. Among the most persistent challenges are volunteer potatoes, which not only compete with onions but also host pests like nematodes. In regions like the Netherlands, this disrupts future potato rotations and undermines regenerative practices. Ecorobotix’s ARA sprayer brings a new level of ultra-precise weed control, now optimized to target volunteer potatoes while protecting onion crops.
The Challenge: Delicate Crops, Persistent Threats
Crops do not compete well with weeds. But worse, volunteer potatoes, resprouting from missed tubers, pose a silent but costly threat.
These plants:
- Increase chemical use and compromise sustainable practices
- Slow down harvest operations and disrupt onion bulb development
- Host nematode pests, threatening future potato crops and breaking regenerative rotation cycles
- Persist through rotations and resist standard herbicides


The Solution: Ultra-High Precision at Plant Level
Ecorobotix’s ARA combines high-resolution cameras and AI to individually detect and treat weeds and volunteer potatoes. This means:
Disease risk mitigation: Break pathogen hosts in rotation
Less chemical, more control: Up to 95% reduction in herbicide use
No crop damage: Phytotoxicity is minimized, ensuring no negative impact on crop development. With the ability to either plant later or harvest earlier than conventional practices, growers can optimize their operations without sacrificing yield.
Optimized harvest quality: Bigger bulbs, higher market value
