Growers and contractors need professional sprayers that handle weed and crop chemicals day in, day out: durable poly, pressure and knapsack-style units with chemical-resistant seals where the chemistry demands it. This is professional-grade gear built to last, not the throwaway retail end of the market.
NORA PRO supplies professional poly and pressure sprayers and knapsack-style units for weed control and horticulture. Tell us your chemical and we will match the unit. Pricing is on quote.
Professional, not disposable
We focus on durable units you re-seal and repair rather than replace each season. Match the seal to the chemical and confirm against the SDS. See the Chemical Compatibility Guide and poly pressure sprayers.
Mixing a weed or crop chemical? The Dilution Calculator turns the label rate, in mL per litre, per cent or per hectare, into mL of concentrate for your tank.
Checking the weather before you spray? The Delta T Calculator works out Delta T from your temperature and humidity, checks the wind against your label and has a printable Delta T chart.

Common questions
What is the best knapsack sprayer for chemicals?
A professional unit with seals matched to your chemical and a comfortable, durable build for all-day use.
Do you supply backpack sprayers, and what seals do they use?
Yes. We stock the Italian made Di Martino 16.0L Professional Backpack Weed Killer Sprayer, with a 1.0L compression chamber, a pressure gauge, a handle that swaps from right to left and a 70 to 110 cm telescopic lance. It has NBR (nitrile) seals for water based herbicides and general weed and pest treatments. NBR is not the seal for acids, caustics or strong solvents, so for those chemicals choose a Klager or Gloria poly sprayer built for them, and send us the SDS.
Do you supply ag resellers in volume?
Yes, through a trade account for wholesale supply.
