Electronic Sprayer – Our Newest Dispenses Herbicides with High Precision as Foam or as Spray
In this piece we identify the key advantages of our new ultra-low pressure electric dispenser (patents pending). (See also this YouTube video: Electronic Dispenser Dispenses Herbicide with High Precision.)
First, when used as a sprayer (i.e., for spraying liquid drops), ultra-low pressure (i.e., less than about 15 psi) offers key benefits. The biggest is less off-target spray. We did indoor testing in 2016, where we sprayed colored water on white paper using a Hypro(R) 30HCX8 hollow cone nozzle. We sprayed at a variety of psi’s. What was particularly striking in these tests was how far the spray extended beyond the primary spray band at higher pressures. At 30 psi, the spray band extended at least 30 inches beyond the center-line! This was an indoor test with no wind. At 9 psi the “shadow spray band” only extend 15 inches. This means, if you are spraying at a high psi, you are doing off-target damage to desirable plants and wasting a lot of expensive herbicide.
Second, ultra-low pressure places far lower demands on the pump and battery. This means our electric sprayer can be far lighter than the competition. Other electric systems typically weigh well over 15 lbs. Ours, even with the fully padded backpack frame, weighs about 10 lbs.!
Third, ultra-low pressure makes great foam! For example, you can hook up our foam-making attachments with the mesh brush. Use it to wipe foam herbicide onto foliage or onto stumps. As shown below, you will get high precision, no drippage (like you do with conventional wiping systems), and extended absorption of the herbicide into the weed’s vascular system because the foam keeps the herbicide in liquid form longer. (Here’s a YouTube video: Cut Stump Treatments)
We will be producing a limited quantity of our Ultra-Low Pressure Electric Dispenser in the first year (2017). We are primarily selling it to professionals with a strong need for the benefits offered by the system. Please contact Green Shoots for availability and pricing!
