Weedseeker System®

The WeedSeeker® spot spray system is an effective solution to help you efficiently control weeds.

The WeedSeeker system senses if a weed is present and signals a spray nozzle to deliver a precise amount of chemical—spraying only the weed and not the bare ground.  It is most effective in areas where weeds occur intermittently.



Cut Weed-Control Costs By Up To 80%

  • Weeds drain the nutrients and water from the soil reducing yield and profits.
  • The WeedSeeker® system helps you save on chemical costs, cut down on time and labor, and reduce the environmental impact of your field activities.
  • Sprays only weeds, not bare ground, and is effective wherever weeds occur intermittently.
  • Used in agriculture, as well as along roadsides, railroad rights-of-way, airport runways, parking lots, parks, hiking trails, etc.


  • Farmers use WeedSeeker systems to control weeds for chem-fallow spraying, no-till field spraying, lay-by spraying, pre-plant weed spraying and post-harvest weed control by automatically spot spraying the weeds and not bare soil.

WeedSeeker System Use

  • The WeedSeeker system uses advanced optics and computer circuitry to sense the presence of a weed.
  • When a weed enters the sensor’s field of view, it signals a spray nozzle to deliver a precise amount of herbicide only to that weed.
  • Herbicide use is reduced 60% to 80% on most spray applications.

Current Practices

  • Self-propelled, utility vehicles, ATVs or pull-behind sprayers all constantly apply herbicide regardless of high or low the weed coverage.
  • Herbicide costs are the same in either situation.


  • Reduce chemical costs up to 80%.
  • Eliminate manual spot spraying crews.
  • Reduce spray passes by combining with mowing or discing equipment.
  • Environmentally friendly.
  • Sprays day or night.
  • Reduces spray drift.
  • Retrofits existing equipment • Sprays only green plants, not bare soil.
  • Economical application of high chemical rates to maximize weed kill.
  • Helps reduce herbicide-resistant weeds.
  • Allows additional spray passes late in the season to kill weeds before seeding.

Simple Operation

  • The WeedSeeker system uses standard pumps, tanks and plumbing so an existing spray boom can be retrofitted or a new spray boom may be purchased

Weedseeker System Equipment

  • WeedSeeker Model 650 or Model 655 sensors are mounted on up to a 150 ft. boom
  • Each sensor applies herbicide in a 12″ or 15″ section of the boom.
  • Operating independently, the sensors automatically spot spray weeds, day or night, at speeds up to 10 mph.
  • For applications that require a higher speed, the system can be set up to spray as fast as 20 mph.
  • A WeedSeeker Sensor is connected to a Line Controller up to 15 per side, 30 total.
