WEATHER INDICATOR DYI TRIALThe idea is to implement the proverbial trial and error technique, letting the greenhorn employee test-spray some utility turf areas behind your equipment shed or other locations where it wouldn’t matter if mistakes were made. When training new employees to use spray equipment, spray indicator dyes can be helpful tools. In addition to the cost savings for product efficiency, retreatments or callbacks will be minimized through more accurate delivery with the first application. Without question, the result will be an increase in performance that will create significant cost savings. Once the new ones are in place, perform a simple spray check on the spray rig, backpack or hand-held sprayer using collection devices to measure the output of each nozzle. Spray indicator dyes can help provide uniform coverage of fungicides, herbicides and fertilizers, which is necessary for the success of any application.Īfter defective or worn spray nozzles have been identified, replace them. By using a colorant, it’s easy to see areas that are left unmarked (but are supposed to be), are partially marked or marked with a lighter color, thus raising a red flag that your sprayer is not up to snuff. When the spray pattern is distorted, the proper volume may be applied, but in a larger or smaller area than desired. In most scenarios, this means a reduction in output. The most obvious is the opportunity to increase effectiveness by identifying clogged nozzles on a spray boom if a nozzle is partially or completely clogged, it alters the amount and distribution of the product. There are many reasons for using a colorant or spray indicator dye. WEATHER INDICATOR DYI SKINUsing the bags also means that there is a reduced possibility of being exposed to the colorant, which means no stains or spills on clothing, skin or the mixing area. Use of the bags is a time-saver, since no measuring is required, and because the colorant bag dissolves in water, there is no waste to dispose of. First, a premeasured dose provides an accurate and consistent application rate. Premeasured bags also offer several other advantages. All that is required of the applicator is to put the correct volume of water (and active ingredient) into the spray tank and drop in the bag of spray dye indicator. Instead of measuring, they use a water-soluble bag with a premeasured amount of colorant in it. One feature that many products offer is ease in mixing. In most cases, the color change is temporary, usually for several hours however, some colors may last up to 48 hours after application. The indicator product changes the color of the contents of the tank, usually to a dark blue or green. Using indicator productsĪs with most other products that are dumped into a spray tank, spray pattern indicators are added in relation to the volume of water in a ratio specified on the product label. Thorough, uniform coverage is necessary for the success of any pesticide or fertilizer application. Have you ever wondered exactly where the insecticide or herbicide in your spray tank hits the ground? It’s not that the formulation is invisible, just hard to see. Spray indicator dye products provide good visual cues.
