2. About WEED-IT

The WEED-IT is a weed control system that recognizes and sprays weeds based on the
fluorescent properties of the chlorophyll molecules in the leaves of living plants. The WEED-IT
uses highly sensitive and accurate sensors. By spraying exactly on top of living plants only, you
will save herbicide while at the same time minimizing environmental load.
Please note that there may be variations in the actual setup of the WEED-IT
system. It is up to the dealer to configure the system in such a way that the
WEED-IT automatically senses which options are available.

2.1 Operating principle

A series of sensors on the WEED-IT detects where the weeds are and immediately sends a
signal to the relevant nozzle to spray the weed with herbicide.
Each sensor has 4 channels; each channel covers 25 cm or 10" (100 cm/40" per sensor).
Depending on the width of the vehicle used for the WEED-IT system, up to 36 sensors may be
used (to treat 36 meters or 120 ft in one operation).
