When selecting products for resistance management there are a few apps out there to help. The app also gives rainfast times for many herbicides.
A more unique app is FS GROWMARK's FS Adjuvant Selector, which recommends spray adjuvants based on a list of given herbicides.

FarmLogic's Tank Mix Calculator is the most fully-featured of the bunch as it allows you to select products from a database for quicker reference and those products are carried over to individual mix lists based on full or partial loads. Clemson's Mix My Sprayer performs similar tasks although only based rates of product per tank size. Syngenta's TankCalc US and DuPont's TankMix feature simple calculators that determine product amounts, gallons of spray solution in a tank and overall product needs for a given area, with TankCalc providing nozzle recommendations. Apps for Mixing and LoadingĪ handful of apps are also available for calculating the correct amounts of spray solution volume and pesticide rates for a given acreage. TeeJet's SpraySelect, Greenleaf's NozzleCalc, HyPro's SprayIt (AgPhD's SprayTipsGuide also recommends HyPro nozzles), John Deere's Nozzle Select, Wilger's TipWizard and Hardi Nozzles all do similar tasks, with a few even allowing you to select nozzles based on common pesticides. Most use the same inputs of application rate, speed, and desired droplet size and pattern to pick nozzles, so choose apps based on your supplier. If you're looking for a new set of nozzles there are a variety of manufacturer-specific apps to ensure that you're picking the best one for the job. The Ag Tools app features a calibration tool out of its list of farm-handy apps and uses inputs of distance traveled, time traveled and output to calculate application rates. The Sprayer Calibration Calculator also gives guidance for adjusting sprayer pressure to reach desired rates. Clemson's Calibrate My Sprayer and the University of Illinois' Sprayer Calibration Calculator allow you to enter target speed, nozzle spacing and application rate to determine the amount to catch for a given sampling period. Apps for Calibration and Nozzle SelectionĬalibration apps take a lot of the confusion out of readying your sprayer every spring.
Assume that you will have to re-learn them every year, because that is what will likely happen each spring. Many of these apps are ones that you will use for only a few months out of the year, which is why I avoid apps that require a login, as inevitably you will become logged out and forget your password, or apps that take a lot of time to master. In general I recommend downloading a few apps that do the same function and spend a few minutes playing around with each one to see what is most intuitive to you. In all the products I've used in Table 1 I never found a one-size-fits-all app you must be willing to have a few that do the same function or pick one that fits 90% of your needs. Fortunately, there are a handful of smartphone and tablet applications that can help navigate through some of the challenges of spraying. Aside from accidents and equipment malfunctions, improper calibration, incorrect nozzle selection or math errors at mixing and loading can result in poor pest control, crop injury from over application or wasted product and money. When it comes to applying pesticides a lot can go wrong.
