Spot Spraying

Spot spray weeds and plants

While most of today’s suppliers of spot spraying technology developed their product as a necessary add-on to their sprayers due to market demand, spot spraying has always been the core of WEED-IT. Detecting, spotting individual weed plants and touching them with the smallest possible amount of herbicide is what every WEED-IT system sold since 1999 is capable of. Right from the start in 1999, WEED-IT has been focussing on a simple yet clever law of nature to detect weeds. Its plant detection principle uses fluorescence technology to detect chlorophyll called the Power of Fluorescence^TM. As every plant and weed requires chlorophyll for its photosynthesis to live and grow, every living plant is naturally detected by the WEED-IT sensors. Moreover, the more chlorophyl a plant contains, the stronger the signal gets and the more ‘chlorophyll fluorescence’ is captured by the sensors. This capability allows for distinguishing larger plants from smaller plants in row crop farming relying on the natural Power of Fluorescence^TM. The fluorescence technology can be best compared to the technology crime scene investigators use to detect even the smallest amount of human blood on a crime scene. If crime fighters rely on it, then why shouldn’t you? We can’t beat nature, right!

In spot spraying mode, WEED-IT targets all living green material on a per plant basis. WEED-IT is suitable to spot spray:

• Individual weed plants on fallow land to maximise moisture availability and to minimise competition and herbicide resistance
• Row crops to target individual plants with liquid fertilisers, plant biostimulants, insecticides and fungicides
• Individual weeds in non-farming situations with mechanical tools, hot water and herbicides

Spot spraying summarised

• Suitable for weeds and plants
• Weed elimination on a per plant level
• Per plant treatment with liquid fertilisers, plant biostimulants, insecticides and fungicides
• Works day and night thanks to its own active light source
• Automatic background calibration
• Individual nozzle control as standard
• PWM technology ensures correct application rate
• Speed and curve compensation
• VRA application possible
• Retrofittable to any type of sprayer
• No pay-per-use based on algorithms, type of weed or acreage covered
• Create heat maps of different activities or rate maps
