Onions including volunteer potatoes

Onion crops are highly sensitive, and any weed competition or crop interference can directly impact size, quality, and yield. Ecorobotix’s ARA sprayer brings a new level of precision weed control, now optimized for volunteer potato management in onion fields.

The Challenge: Delicate Crops, Persistent Threats


Onions don’t compete well with weeds. But worse, volunteer potatoes, resprouting from missed tubers, pose a silent, costly threat. These plants:

Increase chemical use and compromise sustainable practices

Disrupt onion growth and bulb formation

Spread fungal, viral, and bacterial diseases (e.g. Rhizoctonia, Phytophthora infestans, PVY)

Persist through rotations and resist standard herbicides


The Solution: Ultra-High Precision at Plant Level

Ecorobotix’s ARA uses high-res cameras and AI to individually detect and treat weeds and volunteer potatoes—even when they emerge late or unevenly. That means:

Disease risk mitigation: Reduce pathogen hosts in rotation

Less chemical, more control: Up to 95% reduction in herbicide use

No crop damage: Onion rows remain untouched

Optimized harvest quality: Bigger bulbs, higher market value
