John Deere See & Spray Ultimate can substantially reduce targeted, non-residual herbicide use, but it is not a universal “50% less chemical” switch. Boom-mounted cameras and machine-learning software identify crop plants and weeds while the sprayer moves, then open individual nozzles only where weeds are detected. Reported reductions range from 43% to 59% in an Arkansas soybean trial, nearly 50% in John Deere’s 2025 customer data, and 58% in commercial data analyzed by Purdue researchers. Results depend on weed pressure, crop canopy, sensitivity settings, products, equipment cost and licensing.
What See & Spray Ultimate does
See & Spray Ultimate is John Deere’s high-end targeted-spraying configuration for in-crop, or green-on-green, applications. It is intended primarily for corn, soybeans and cotton, subject to the supported model, software and crop-stage configuration. Cameras mounted along the boom scan the rows and ground; onboard processors classify crop plants versus non-crop vegetation; and nozzle controllers trigger individual nozzles as detected weeds pass underneath.

That differs from green-on-brown systems, which detect living vegetation against soil or dead residue in fallow fields. Ultimate’s defining use case is post-emergence weed treatment inside a growing crop. John Deere describes the system here: See & Spray product information.

- Cameras capture the crop row and soil ahead of the boom.
- Machine-learning software analyzes each image in real time.
- The controller distinguishes likely crop plants from unwanted vegetation; it does not identify every species perfectly.
- It predicts when a detected weed will reach each nozzle.
- Individual nozzles open for the required spray duration and then close.
- Supported configurations record application information and can produce as-applied and weed-pressure maps.
Lighting, dust, glare, rain, residue, crop stage, canopy overlap, weed size, plant density and travel speed all affect detection. Operators still need scouting, calibration, label-compliant rates and a plan for missed weeds or system faults.

What “less chemical” actually measures
Most headline figures compare the amount of targeted non-residual herbicide applied with See & Spray against a broadcast treatment. They do not necessarily mean that total crop-protection chemistry, active ingredient, water volume or program cost falls by the same percentage.
- Residual herbicides may still need broadcast coverage.
- A smaller sprayed area does not mean a lower labeled rate on each weed.
- Carrier or water volume can differ from active-ingredient volume.
- An additional pass can erase part of the savings through fuel, labor and machinery costs.
- Dual-tank operation can apply a targeted product and a separate broadcast or targeted product in one pass.
In one Illinois soybean trial using a dual-product program, John Deere reported 47% less herbicide volume and 7% better weed control than the comparison treatment. Those are results from that trial, not a guarantee for every field: trial report.
How large are the savings?
| Evidence | Reported result | How to interpret it |
|---|---|---|
| John Deere customer deployments, 2025 | Nearly 50% average reduction in non-residual herbicide use; more than 5 million acres and nearly 31 million gallons of mix saved | Company-reported aggregate, not a guaranteed farm result |
| University of Arkansas, three-year soybean trial | 43%–59% lower herbicide use | Specific crop, geography and experimental conditions |
| John Deere Illinois soybean trial | 47% less herbicide volume and 7% better weed control | One dual-product program |
| Purdue commercial-data analysis | 58% reduction in targeted herbicides | Commercial data; modeled economics vary by assumptions |
| Iowa State field example | 4,700 gallons of tank mix and about $6,500 in product across 415 acres | One field-scale example, not a benchmark for every farm |

Yield claims need attribution
John Deere says sponsored third-party soybean research across seven states averaged a 2.0-bushel-per-acre yield increase, with a reported upper result of 4.8 bushels per acre. The company identifies the sponsorship; these figures should not be treated as an expected increase on every farm.
Why weed pressure determines the result
Targeted spraying has the greatest percentage advantage when weeds occupy a small, uneven portion of the field. If weeds cover most of the ground, the system must spray much of the same area as a broadcast pass. Purdue’s analysis reported average weed-area differences of about 5.1% in soybean and 16.6% in cotton in its commercial data, illustrating why crop and field conditions matter.
- Low or patchy pressure: large unsprayed areas can produce substantial product savings.
- Moderate pressure: savings remain possible, but vary by field and timing.
- Dense infestations: the area advantage narrows; placement, crop-safety and dual-product benefits may become more important than volume reduction.
Pressure also changes between fields and years. A farm should use its own scouting records and as-applied maps rather than extrapolating one percentage to every acre.
Sensitivity settings create an agronomic trade-off
Lower sensitivity generally detects and sprays less vegetation, while higher sensitivity catches more potential weeds at the cost of more product. The lowest setting is therefore not automatically the best setting.

In the Arkansas soybean work, the lowest sensitivity setting was associated with a 280% annual increase in the soil weed seedbank under the study conditions. That finding makes sensitivity a long-term weed-management decision: short-term input savings can be offset by escapes, seed production and future resistance pressure. Set the threshold with the weed species, size, crop stage, herbicide activity and escape tolerance in mind, then inspect fields for misses.
Why Ultimate’s dual-tank design matters
Ultimate is associated with an integrated split-tank or dual-product configuration. One tank can deliver a targeted product to detected weeds while the other carries a broadcast or separately targeted product. This can avoid some tank-mix antagonisms and make it possible to combine a residual program with a post-emergence targeted treatment.
The flexibility adds work: separate product logistics, compatibility checks, calibration, cleanout and inventory management. The Illinois trial’s result was tied to a specific dual-product program, so the feature should be evaluated as part of an agronomic plan rather than as a savings number by itself.

Does it pay for itself?
The purchase decision depends on acres, product cost, weed pressure and the ownership or licensing model. Purdue’s 2026 economic model estimated that a farm needed to spend more than $39 per hectare on herbicides in a single application for its modeled Ultimate system to break even against broadcast spraying. The modeled equipment values were approximately $900,000 for Ultimate and $750,000 for Premium. These are scenario assumptions, not universal list prices or a farm-specific recommendation.
Do these 3 things before closing this tab:
1Scan for outdated or missing drivers - takes under a minute2Clear out junk files and repair common Windows errors3Fix the driver behind crashes, sound loss and screen glitchesUse this framework with your own numbers:
- Targeted non-residual product savings.
- Any demonstrated crop-injury or yield benefit.
- Labor, water or pass savings that are actually avoided.
- Equipment premium, financing, maintenance and training.
- Software license charges.
- Extra passes required for residuals or missed timing windows.
- The cost of escapes, seed production and resistance management.
High annual acreage improves cost spreading. Consistently heavy weed pressure, low herbicide expenditure or an incompatible sprayer makes the payback harder.
Licensing, model years and equipment limits
John Deere’s current Gen 2 description says single-product hardware is standard on 2027-and-newer 400R and 600R sprayers, subject to configuration and factory deductions, while in-crop applications require a renewable software license. Targeted fallow applications are described as having no additional cost. John Deere also announced an unlimited annual license option for high-use operations for the 2026 season; U.S. pricing requires a dealer quote.

A Canadian support page listed See & Spray Unlimited at C$38,000 per license as a single upfront price and described in-crop pricing of C$6 per acre not sprayed. That is a Canada-specific price signal, not U.S. pricing: Canadian licensing page.
Eligibility varies by model year, configuration, cameras, processors, display, connectivity and nozzle-control hardware. An Arkansas Extension fact sheet reported that the Ultimate configuration it evaluated could not be retrofitted. Do not assume a used or existing sprayer qualifies without a written compatibility and upgrade assessment: Arkansas fact sheet.
Operational limitations and recovery planning
- Confirm supported crops, crop stages and maximum effective speed.
- Check herbicide labels for targeted application requirements and required broadcast residual coverage.
- Keep cameras clean and inspect detection in dust, glare, rain, residue and heavy canopy.
- Define what happens when confidence is low, a camera is blocked or the system faults; operators may need to revert to broadcast mode.
- Maintain nozzles, filters, pressure control and calibration just as with a conventional sprayer.
- Scout after spraying for escapes and adjust sensitivity or program timing.
See & Spray reduces unnecessary coverage; it does not replace resistance management, residual herbicides where appropriate, label rates, timely applications or agronomic judgment.
Ultimate compared with other options
| System | Best fit | Key distinction |
|---|---|---|
| See & Spray Premium | Owners of eligible John Deere sprayers needing in-crop targeting | Upgrade path for specified MY18–MY26 R-Series and 400/600 Series machines; no Ultimate dual-tank configuration |
| See & Spray Select | Fallow or green-on-brown applications | John Deere advertises 77% average savings under its stated fallow test conditions; not an in-crop equivalent |
| Greeneye Technology | Operators comparing a non-Deere precision-spraying platform | Check machine compatibility, regional service and data integration; research context is available here |
| Bosch–BASF One Smart Spray | Farms seeking another commercial precision-spraying system | Compare supported sprayers, crops, licensing, service and data workflows |
Green-on-brown systems such as Trimble WeedSeeker can be a better fit for fallow, pre-emergence, pasture or residue-visible work; they should not be treated as interchangeable with Ultimate’s green-on-green capability.
Questions to put in a dealer quote
- Is the proposed machine factory-equipped, upgradeable or incompatible with Ultimate?
- Which crops, stages and speeds are supported in my region and software version?
- What are the per-acre, annual and unlimited license options?
- Can targeted and broadcast products run in one pass, and what mixing or cleanout procedures apply?
- What happens when cameras are obstructed or detection is unavailable?
- How are weed-pressure and as-applied maps exported to my farm-management system?
- What warranty, connectivity, service response and operator training are included?
- What savings assumptions are being used for fields with my weed pressure and herbicide program?
Bottom line
See & Spray Ultimate is a real precision-spraying system with credible evidence of materially lower targeted herbicide use. The strongest reported results cluster around roughly half of non-residual herbicide volume, but the outcome can be far lower or higher depending on weed density, canopy, sensitivity, product program and field execution. The system makes the most economic sense for high-acreage operations with compatible equipment, spatially variable weeds and a disciplined plan for residuals, escapes and licensing. Treat every percentage as a scenario to validate with field data—not as a guaranteed farm-wide reduction.
