Equipment categories and suitability for farm sizes
- Manual knapsack sprayers: Lever-operated sprayers holding 12 to 16 litres, offering low-cost plant protection for small plots and kitchen gardens.
- Battery-operated sprayers: Rechargeable 12V lead-acid or lithium-ion powered units delivering steady pressure with zero pumping effort.
- Motorized engine sprayers: 2-stroke or 4-stroke petrol-driven portable or knapsack sprayers designed for tall horticultural trees and dense orchard crops.
- Tractor-drawn boom sprayers: High-capacity multi-nozzle sprayers operated via tractor PTO, ideal for large acreages of wheat, cotton, and soybean.
Key technical features to compare before purchasing
- Tank material: High-density polyethylene (HDPE) with UV stabilizers prevents degradation from sunlight and corrosive chemicals.
- Pump mechanism: Brass cylinder piston pumps provide higher pressure durability for power sprayers, while diaphragm pumps handle wettable powders better.
- Nozzle package: Sprayers should include interchangeable flat-fan nozzles for herbicides and hollow-cone nozzles for foliar insecticides.

Common questions
What is the most cost-effective sprayer for a smallholder farmer?
A rechargeable 12-volt battery-operated knapsack sprayer provides the best balance of affordability, constant pressure, and low physical effort.
Where can farmers view approved equipment lists and apply for sprayer subsidies?
Official approved equipment lists and subsidy application forms are accessible on the national SMAM portal at agrimachinery.nic.in.
How do I maintain an agriculture spray machine for long service life?
Always triple-rinse the chemical tank, pump lines, and nozzles with clean water immediately after every spraying operation to prevent nozzle clogs and seal corrosion.
