Crop info
Broadleaf weeds, chickweed, poppy, cleavers, fat hen, thistles, stand out clearly against the crop in cereals. That makes cereals ideally suited to spot detection and treatment from the drone. Two moments are worthwhile: in spring before the broadleaf spray, and on the stubble after harvest to reduce survivors and root weeds before the follow-on crop. That way you use the cereal year to make the field structurally cleaner.
TARGET SPECIES
In spring you clean broadleaf weeds that stand out in the cereals: chickweed, poppy, cleavers, fat hen and chamomile. On the stubble after harvest you focus on root weeds and survivors such as thistles (Cirsium arvense) and couch grass. That way the field gets cleaner season after season.
BLACK-GRASS
Black-grass is the most important grass weed in cereals. It is chemically closely related to the crop itself, which makes selective control difficult. In spring Croptic can map the black-grass patches, so you can spot-spray precisely where it really matters.
SEASONAL CALENDAR
Cereals are sown in autumn and overwinter. In a cereal year there are two worthwhile drone moments: the spring window (March–June) to prevent seed formation, and the stubble window (August–September) to clean fields in a targeted way after harvest before a follow-on crop.
Season calendar
Winter wheat: Oct–Nov, winter barley: Sep–Oct
GS21–GS32: tillering → stem extension
Optimal moment for broadleaf weeds
Barley: early Jul, wheat: 20 Jul
After harvest: targeted cleaning of survivors
Step 01
You or one of our partners fly a drone over your field as soon as the broadleaf weeds are visible in spring, or after regermination on the stubble. The camera captures every detail in high resolution.
Step 02
Our AI analyses the imagery and distinguishes weeds in spring, and survivors on the stubble. That way you decide which weeds go into the weed map.
Step 03
You load the weed map into your GPS sprayer with section control. Nozzles open and close automatically over the weeds. You only treat where needed, and the rest of the field stays untouched.

CONTEXT
Broadleaf weeds seed heavily if you let them stand. And root weeds are often hard to control in follow-on crops. Cereals are the crop for reducing that seed bank: in spring tackle broadleaf weeds spot by spot, after harvest clean survivors precisely on the stubble. Result: a cleaner field for whatever follows, with fewer residues and less resistance pressure.
