Trimble launches new WeedSeeker 2 spot spray system

Trimble has announced its next-generation WeedSeeker 2 spot spray system. According to the manufacturer, this new sensor solution and system provides growers up to 90% savings in input costs when targeting and treating herbicide resistant weeds.

Intelligent sensors

New intelligent sensors save time in the field by eliminating the need for system resets. After a quick calibration upon powering on, WeedSeeker 2 automatically adjusts on the run to changing temperatures, ambient light, and shifting backgrounds like soil or stubble, assuring sensor accuracy in all conditions.

New intelligent sensors save time in the field by eliminating the need for system resets.

These smart sensors also know the speed and their position on the sprayer boom. According to Trimble that means they won’t spray sections of the field that have already been covered, and will automatically adjust spray timing when making a turn to ensure a weed is covered.

Detailed maps

The WeedSeeker 2 system now logs every weed sprayed, so users can see in real time where there are problem areas and review detailed maps from records before the next spray.

Trimble says WeedSeeker 2 is lighter and more agile on the largest sprayer booms and the sensors now provide expanded coverage areas. The new sensors eliminate the need for nozzle reconfigurations and reduce the number of sensors needed.

“Selective spraying is a great tool for weed control, especially against those that show tolerance or resistance to the most common herbicides,” said Daniel Rodriguez, WeedSeeker product manager for Trimble Agriculture.

Save up to 90% on chemical costs

According to Rodriguez, by applying herbicide only on targeted weeds, farmers can save up to 90% on chemical costs. “This makes it possible to use products with different modes of attack that would otherwise be cost prohibitive. The WeedSeeker 2 detection system allows you to use it not only on fallow fields, but also after planting, which extends the usage window of the equipment and improves field recovery.”

Compatible with Trimble displays

The new system is fully compatible with Trimble displays, positioning services and Autopilot vehicle guidance. The GFX-750 display system can quickly transition between the run screens for guidance and spot spraying while simultaneously controlling both, allowing a cleaner tractor cab and eliminating the need for multiple displays for guidance and sprayer control.

Trimble displays and auto-guidance are not required; any Isobus compatible display with universal terminal capability can be used to monitor and control the new spot spray system.

Easier to clean and maintain

The system comes with a universal mount that fits on most sprayer boom configurations. Trimble says the WeedSeeker 2 features a redesigned housing that is easier to clean and maintain. Channels built into the sensor housing allow liquid to drain no matter the boom position. This should reduce the need to clean the system due to unexpected rain or other environmental impacts.

The upgraded processing power allows sprayer operating speeds of up to 40 kilometers (25 miles) per hour.
