Knapsack vs Boom Sprayer: Which is Right for Your South African Farm?
22 May 2026 · 6 min read · Agristart Team
Spraying is one of the highest input costs on a South African farm — both in chemical and in labour. The right sprayer cuts both.
Knapsack sprayers
Best for plots under 2 hectares, spot spraying and orchards with limited tractor access. Battery-powered knapsacks have become the standard — they're faster, less tiring and give more consistent pressure than hand-pump units.
Mist blowers
Ideal for citrus, macadamia and table-grape blocks in Limpopo, Mpumalanga and the Western Cape. Penetration into dense canopies is far better than a knapsack.
Boom sprayers
From 5 hectares up, a tractor-mounted boom sprayer pays back in a season on labour alone. Look for stainless or polyethylene tanks, anti-drip nozzles, and a boom width that matches your tramlines.
Water and chemical handling
South African boreholes often produce hard water that clogs nozzles. Fit an inline filter, flush the tank after every spray day, and store concentrate out of direct sun. See our Spraying Equipment range for knapsack, mist and boom options.
