Reducing Phytotoxicity Levels in Onions Thanks to ARA

Recent feedback from our ongoing onion trial using the ARA precision sprayer is leaving the Ecorobotix team optimistic.

The onion field was divided into two parts to compare phytotoxicity in crop herbicide treatment between conventional application and the ARA ultra-precision sprayer. One section was applied with the ARA ultra-precision sprayer precisely on the weeds without touching the onions (with an unprecedented precision of 2.4x2.4in (6x6cm)) and the other section by blanket spraying with a conventional sprayer.

Preliminary Results

The team noted a clear growth defect on the onions sprayed with the conventional sprayer, the onions are considerably smaller than the onions in the plots treated with ARA. Overall crop health with the ARA sprayer seems much higher than with the conventional spraying method, even when increasing the dosages of the herbicides used.

Further testing will be completed, and conclusive results are to be published towards the end of the season.
