Onion

The Onion Algorithm used by the ARA™ UHP Sprayer is setting a new standard in sustainable agriculture. For onion growers, their benefits are great especially when it comes to minimizing phytotoxicity.

Scan and detect weeds with Artificial Intelligence (AI)

Our advanced Plant-by-Plant AI™ technology detects weeds of sub-centimeter size in your onion crop, even in the onion rows. It targets them in less than 1/4 of a second on a footprint as small as 6 by 6 cm.

Treat Only What's Needed

Our advanced Plant-by-Plant AI™ technology detects weeds of
sub-centimeter size in your onion crop, even in the onion rows. It
targets them in less than 1/4 of a second on a footprint as small

Visible Results

Phytotoxicity and weed pressure both impact yield quantity. In the example below ARA proves it doesn't just do the job, it actually gets better results than standard broadcast spraying

No herbicides are applied—used as a control in tests. Weak yield results due to uncontrolled weed pressure.

Non-Treated (Class mm)

AI targets specific weeds, spraying only them with selective herbicides. Result shows a higher yield than broadcast spraying.

ARA, Selective (Class mm)

AI sprays only weeds with non-selective herbicides, avoiding crops. Result shows a higher yield than broadcast spraying.

ARA, Non-Selective (Class mm)

Herbicides are sprayed evenly across an entire field, covering both weeds & crops. Weed pressure is controlled, but yield suffered from phytotoxicity.

Broadcast Spraying (Class mm)

We sprayed 20 acres with a total of 60 gallons. Normally we would use about 1,000 gallons to cover the whole field. We used 1 ounce of active ingredient across the whole field where we usually would use 16 ounces. While using ARA, the onions had really good color and really good shape, totally unaffected by the spray.

Proven Results: Data from 3,000 Onion Missions

Our study, which analyzed nearly 3,000 ARA sprayer missions in onion fields, reveals that ARA saved nearly 80% of herbicide per hectare in 2023 compared to conventional broadcast spraying. Furthermore, ARA efficiently eliminated weeds while reducing the phytotoxic effects of chemical inputs, ensuring higher yields per hectare compared to both conventional application and untreated control.

Untreated Control

No treatment applied. Onions and weeds are in direct competition for soil nutrients, water and light.

Broadcast Conventional Treatment

Broadcast treatment applied. Onion plants are weakened by the contact with the herbicides. (result shows 7 days after treatment)

ARA Spot Spray Treatment

Onion plot treated with ARA. Precise spraying ensures clean rows and vigorous, healthy crops.(result shows 7 days after treatment)

Each dot shows the herbicide saving for each single mission ARA led in onions in 2023.

Proven Benefits

-> Higher yield potential – By avoiding phytotoxicity, onions grow stronger and bigger.
-> Lower Input Costs – Reduce plant protection product expenses while improving overall farm profitability.
-> Environmentally Sustainable – Reduce chemical runoff, improve soil health and air pollution.
