Optocleaner [ òptō – kle´enər
] is optical equipment/machines for removing weed, pests, algae,
UV light is "clean technology" and very efficient for weed control.
UV light removes
the green energy producing part above ground.
The roots respond by sending up new shots, which will greatly weaken the root system.
Before new shots get taller than an inch, the UV treatment has to be repeated to avoid any resupply from the new shots to the roots.
grass and “ordinary” weed only needs a few treatments to become tiny.
Removing shoots several times depletes the energy reserves of weed stored deep underground as it has to resprout.
If the losses is 50% the first time, 20% the second time etc. it may take less than 12 treatments to dry out even difficult old weed.
The number of treatments is comparable to the other thermal methods - flaming by gas burner, infrared light, hot water or steam.
It is important
not to stop the treatment as the last tiny sprouts will gradually resupply the
roots energy reserves unless they are removed.
Next the earth is clean and will be easy to maintain - even at high speed if UV weed control is used.
