Major power sprayer categories
- Knapsack engine sprayers (2-stroke / 4-stroke): Portable backpack sprayers generating 15 to 25 bar pressure, ideal for paddy, cotton, vegetables, and pulses.
- Battery-operated sprayers: Rechargeable 12V lithium-ion or lead-acid knapsack sprayers offering quiet, emission-free operation for smallholders.
- Tractor-mounted HTP (Horizontal Triplex Pump) sprayers: High-capacity piston pumps operating at 30 to 50 bar pressure with multi-outlet delivery hoses, indispensable for tall orchards like mango, citrus, and pomegranate.
Calibration, nozzle maintenance and operating pressure
Calibrate the sprayer prior to seasonal spraying by measuring liquid output over a fixed area to ensure accurate dosage delivery per acre. Use hollow-cone nozzles for foliar insecticides and fungicides to achieve fine canopy coverage, and flat-fan nozzles for soil-applied herbicides. Clean suction line strainers and lubricate pump plungers regularly.
Government subsidies under SMAM
- Power sprayers qualify for 40% to 50% capital subsidies under the Sub-Mission on Agricultural Mechanization (SMAM).
- Higher subsidy percentages are allocated for small, marginal, SC/ST, and women farmers.
- Farmers apply online via the national agricultural machinery portal (agrimachinery.nic.in) or state agriculture DBT portals.

Common questions
What is the primary advantage of a 4-stroke power sprayer over a 2-stroke model?
4-stroke power sprayers run on pure petrol without needing 2T engine oil mixing, produce less exhaust smoke, deliver higher fuel efficiency, and offer longer engine life.
What type of power sprayer is best for commercial fruit orchards?
A tractor-mounted or portable engine-driven HTP (Horizontal Triplex Pump) sprayer, which delivers 30 to 40 bar pressure to reach tall tree crowns.
Where can farmers apply for government subsidies on power sprayers?
On the central SMAM portal (agrimachinery.nic.in) or their state department of agriculture mechanization DBT portal.
