WEED-IT is a plant detection technology at applies chemical only to the target instead of spraying bare ground.
Intelligent sensors sample the ground 40,000 times per second searching for living plant matter up to speeds of 15mph. Ground speed is measured and will adjust application timing so that the target is within the spray pattern.
WEED-IT runs on a standard 12 volt system. Power is connected directly to the battery and runs to an interface box. The interface box does many tasks, one of them is to invert 12 volts up to 48 volts. A low voltage system suffers high power loss over large distances, so to overcome this WEED-IT inverts 12 volts to higher voltage levels so that power loss across large 120ft booms is minimized.
One interface box has enough power to run a 120ft system without any additional components.
WEED-IT has been around for over 18 years. This technology was first invented and released into Holland in 2001.
European environmental departments raised their concerns of blanket chemical usage over footpaths and street gutters. WEED-IT was developed to address this issue and come up with the solution that now only sprays 10% of blanket rates across many local councils in Europe. The technology is most commonly fitted to quad bikes where operators scope footpaths, roadway and gutters for weeds.
In March 2009, the WEED-IT company was approached in the interest to modify this system so that it could be used for summer spraying in the broad acre farming conditions. After significant testing in the south of France with very pleasing results, November 2009 saw the first production system arrive into Australia.
Since then there have been over tens of thousands of sensors sold into Australia, Argentina, Brazil, Canada, Russia, and now U.S.A. Systems are sold to growers, corporate clients and custom applicators. The results continue to bring testimony to the value of WEED-IT.
Weed detection and elimination has become a priority for farmers across the world with the changing summer rainfall patterns, herbicide restrictions, and the increase in weed resistance. WEED-IT Quadro is helping farmers everywhere to decrease their chemical usage and fight weed resistance with its precision spraying technology.
WEED-IT Is Designed To Run Day Or Night
WEED-IT System Includes:
Weed-it control unit
WEED-It comes with a separate water proof module that is mounted in the cab of the sprayer. This module is used to control application rates, for diagnostics, and programming. It can be paired with some GPS systems to track spray rates and weed density.
The WEED-IT will work with any type of pump, as long as it provides the required amount of liquid to feed all the nozzles along the boom. To maintain the pressure to all these nozzles, the system needs a Ramsay valve (pressure accumulator, membrane valve) in the spray line. It is controlled by a small air compressor. If the spraying system already has an air compressor, this can also be used for the WEED-IT system. When the pressure exceeds 6.0 bar (85 psi) the unused fluid flow goes back into the tank via a return line (dump line). We recommend WEED-It be run at a 3.0 bar or (43.5 psi) pressure.
