WEED-IT Precision Spraying Technology

WEED-IT is a world-leading, sensor-based spraying system that helps farmers control weeds more sustainably and cost-effectively. Instead of blanket-spraying the whole paddock, WEED-IT only applies chemical where weeds are actually growing – saving you money, product and time.

🌿 How WEED-IT Works

Using advanced optical sensors, WEED-IT detects chlorophyll (the green pigment in weeds) in real time. When a weed is identified:

  1. The system immediately activates the correct nozzle

  2. Herbicide is sprayed directly on the weed – within milliseconds

  3. No chemical is wasted between plants

This smart technology performs consistently in full sun or after dark, across a range of speeds, soil types and crop conditions.

πŸ” Why Farmers Choose WEED-IT

  • Use up to 95% less herbicide – huge input savings

  • Reduce environmental impact – less chemical runoff and drift

  • Fast ROI – less product used = more profit retained

  • Fully digital system – automatic logging, task maps, ISOBUS ready

WEED-IT Spot Spraying – Hit Every Weed, Save Every Dollar

  • The original pioneer of spot spraying technology, with every system sold since 1999 capable of detecting and treating individual weeds with pinpoint accuracy. Backed by world-leading fluorescence sensor technology, WEED-IT helps farmers target only what needs spraying – saving up to 95% on chemical use while delivering unmatched weed kill rates.

  • WEED-IT sensors detect chlorophyll (the green pigment found in living plants) using a technology called chlorophyll fluorescence. Once a weed is detected, the system automatically opens a nozzle directly above the plant – applying herbicide within milliseconds.

    This allows you to treat individual weeds instead of entire paddocks, reducing chemical usage, protecting soil, and slowing herbicide resistance.

    • Up to 98% weed hit rates – almost no weeds left behind

    • Per-plant precision – targets only living green weeds

    • Works day or night, even in dusty or variable conditions

    • Standard PWM + individual nozzle control

    • Fully retrofittable to any sprayer type or brand

    • Automatic background calibration for maximum accuracy

    • Speed & curve compensation to maintain correct rates

    • Suitable for herbicides, fertilisers, insecticides, fungicides & biostimulants

    • Fallow paddocks – remove weeds to conserve moisture & prevent resistance

    • Row crops – per-plant treatment with crop-safe products

    • Non-farming areas – spot-spray weeds along fencelines, roadsides, headlands

  • From Spot Spraying to Dual, Cover and Spot-in-Crop modes, WEED-IT is the only precision spraying system that meets all your spraying needs in one setup.

    Western Mechanical can supply, install and support WEED-IT Spot Spraying systems to suit your current sprayer – with expert advice, retrofit kits, and ongoing backup.

WEED-IT Spot-in-Crop – Precision Green-on-Green Weed Control

WEED-IT for Broadacre Farming –

  • Broadacre winter and summer crops such as wheat, barley, chickpeas, mungbeans, cotton, sorghum and sugarcane are where WEED-IT earned its reputation. Designed specifically for large-scale farming operations, WEED-IT delivers unmatched per-plant weed control using intelligent fluorescence-based spot spraying technology.

  • Rather than blanket spraying entire paddocks, WEED-IT QUADRO detects individual green weeds and applies herbicide only where needed.
