Weed-It Isobus implementation certified by AEF

Weed-It passed the Isobus test of the Agricultural Industry Electronics Foundation (AEF) successfully. Weed-It is now officially certified for Isobus operations. It is the first precision spot spraying system to be part of the AEF Isobus Database.

With Isobus, users can control their Weed-It system from their own terminal in the tractor or self-propelled sprayer and prevent unnecessary spraying with section control.

Weed-It is developed by Dutch company Rometron. The company says it can be built onto any type and brand of ground glider and trailed sprayer, quad, orchard sprayer, toolbar, self-propelled sprayer and even autonomous sprayers with working widths up to 36 m.

Weed-It offers three application methods

The system detects weeds in the field using sensors and sprays only the weeds. According to Rometron, this can help save growers up to 90% on chemical costs. Weed-It offers three different application methods. Spot Spray targets all living green material on fallow land. Dual Spray applies a low application rate (30 l/ha for instance) full width and a higher rate (100l/ha for instance) on every single weed detected. In Full Coverage mode growers can apply any type of herbicide, insecticide and fungicide with up to 200 Hz PWM technology.

For the past few months, Rometron has been working on Isobus functionality, with Isobus implementation specialist WDSA. It passed all tests of the Isobus Test Centre in Osnabrück (Germany).

User benefits

The Isobus implementation on the Weed-It system consists of three main aspects and user benefits:

  1. Virtual terminal (UT): controlling Weed-It from the terminal of the tractor or self-propelled sprayer
  2. Section control (TC-BAS and TC-SC): to prevent overlap of already sprayed parts of the field, the terminal of the tractor or self-propelled sprayer can control which Weed-It sensors should spray and which not
  3. Weed mapping (TC-GEO): all parts of the field where a weed was hit by WEED-IT, are reported back to the terminal to generate a weed-map

The availability and operability of these features depends on the Isobus compatibilities and licenses of tractor-sprayer combinations, self-propelled sprayers and operator terminals.

Available from mid-2021

If all further field testing goes according to plan, the Weed-It Isobus implementation is expected to be commercially available from mid-2021. Existing Weed-It Quadro users can benefit from the backward compatibility of the Isobus implementation.

An upgrade consists of hardware components and a software upgrade for the user console. Further information on upgrades and pricing will be provided once all field testing and validation is completed and it’s ready for commercial release.
