Twenty-five years ago Roel de Jonge revolutionized the precision technology market with his spot spray technology, WEED-IT. He gave farmers the ability to save drastically on their herbicide costs to maintain their chem fallow acres, as well as bettering the environment.
Now twenty-five years later, there are several companies who have followed suite in developing their own precision spray technologies, but why is WEED-IT still a popular choice for spot spraying? What holds WEED-IT apart from other spot spray technologies? The Power of Fluorescence.
What is Fluorescence? Fluorescence is the property of absorbing light of a short wavelength and emitting light of a longer wavelength. 
WEED-IT takes the natural light absorption properties of chlorophyll to detect weeds and plants. WEED-IT sensors emit a short wavelength of red light which is partially absorbed by chlorophyll and then detects the longer wavelengths of infrared light reflected by chlorophyll. In essence, by using fluorescence the plants appear to glow to the WEED-IT sensor making it hard for WEED-IT to miss even the smallest of weeds day or night.
Fluorescence is a simple process, and simplicity equals accuracy and reliability. WEED-IT has a 95% accuracy rate in detecting chlorophyll in amounts as small as a US quarter. It also does not require frequent software updates as it. is simply looking for chlorophyll. There is a one-time calibration at the time of installation and that’s it.
The Power of Fluorescence allows for versatility in chemical applications. WEED-IT is most known for its herbicide applications on chem fallow ground, but it has also been used for a variety of top dress applications. Since WEED-IT only detects infrared light reflected off chlorophyll it will only apply chemistries to individual plants. WEED-IT customers have used the Power of Fluorescence for desiccation, defoliating cotton, top dressing sunflowers, lettuce plants, and cucumber plants.
Other benefits to the WEED-IT precision spray system is that there are no subscriptions! You buy it and you own it. It can be retrofitted to most sprayers both self-propels and pull-types. WEED-IT offers four different spray modes to suit all of your spraying needs. And its 10” nozzle spacing allows for the highest level of efficiency with minimal waste.
