The WeedSeeker® technology uses sensors and nozzles spaced at 380mm apart. This spacing is due to a narrower field of view of the sensors compared to a 500mm spacing on a standard boom. The WeedSeeker® will spray only weeds, not bare ground. WeedSeeker® technology is effective wherever weeds occur intermittently, and can be fitted to most boom sprays.
WeedSeeker® is being used in agriculture, irrigation districts, along roadsides, railway corridors, airport runways, golf courses, parking lots, median strips, parks and hiking trails, etc. The possibilities are limitless.
DPI research in Northern NSW has shown that the average weed cover in fallow paddocks is as low as 20% of the paddock area. This means that often 80% of the herbicide is applied to bare soil and is wasted. This is inefficient, expensive and environmentally unsustainable.
Reduce herbicide costs – Australian research has shown savings in herbicide use on cotton, soybeans and fallows commonly in the range of 50-80%. Commercial use of the Weedseeker® systems in the northern cropping area over the last four years has resulted in a reduction in fallow herbicide use of up to 90%.
Herbicide resistance – The emergence of hard to kill fallow weeds such as fleabane, peachvine, milkthistle, roundup ready cotton and marshmallow has become an increasing issue in the northern cropping region. Australia was one of the first countries in the world to discover resistance in annual rye grass (Lolium sp) to the common fallow herbicide Glyphosate. The Weedseeker® allows you to use mixtures of different herbicide groups, which may be currently too expensive to apply in a blanket application. This will prolong the life of existing herbicides and reduce resistance in weed populations greatly improving sustainability of cropping systems.
Reduction in herbicide drift – The total chemical released by the boom is substantially lower due to only spraying the weeds and not bare soil. The risk of herbicide drifting onto non-target areas and the surrounding environment is reduced.
Increased adoption of no-till – Reduced tillage cropping systems can provide environmental benefits in terms of reducing soil erosion by wind and water. Reducing herbicide use improves returns further and allows more farmers to adopt the system to the benefit of the whole agricultural landscape.
Environmental – reducing pesticide load in the environment benefits the whole community.
Water savings – reduce the amount of water used by covering more hectares per tank load. Save time not having to fill tanks as often.
