Tell us what is standing in your field.
Send your field through and tell us which weed you see. Then we will say whether we can map it.
Weed patches
Patches mapped before they spread.
Some weeds grow in patches that get bigger every year. On the drone images those spots stand out between the crop.
The map
Every patch in its place.
Some weeds grow in patches that get bigger every year. On the drone images those spots stand out between the crop, with their boundary and their area.
- The AI recognises weeds from about 3 centimetres, with species recognition and georeferencing.
- The map stays in your account, so you find the same spot again next season.
- Every map passes Lander before it reaches you.
Why patches
A patch left standing comes back bigger.
Yellow nutsedge, thistles and dock spread out from one spot. What you leave this year stands wider next year, and soil movement drags it across the rest of the field.
- A yellow nutsedge plant makes about 500 tubers per season in our climate, and those stay viable for years.
- A rotary harrow can drag tubers up to 40 metres, so work an infested field last and clean the machine.
- A dock plant makes around 7,000 seeds a year on average and regrows from root fragments.
What you do with it
A record that lasts several years.
In Flanders there is no reporting duty for yellow nutsedge, but there is a control duty and a ban on growing bulb, tuber and root crops on an infested field. In the Netherlands a growing ban applies to the infested part.
- In Flanders a field counts as infested from more than 10 square metres of infestation, and that is exactly what a map records.
- By flying again every year you see whether the patch is shrinking or growing.
Questions
Questions about patches.
Yellow nutsedge is the best known example. Thistles and dock grow the same way, out from a spot that keeps expanding.
When the weed rises above the crop or clearly differs from it. Tell us which crop is standing and we look at the timing with you.
You act precisely on the spots it shows, and you find those same spots next season to see whether they have got smaller.
In Flanders there is no reporting duty any more, but there is a control duty and a ban on growing bulb, tuber and root crops on an infested field. In the Netherlands inspection runs via the NVWA and the inspection services.
Yes. Where the weed is detectable and your sprayer reads a task map, we deliver the patches as a task map straight away.
