Types of manual hand sprayers in Indian farming
Farmers select manual sprayers based on acreage, crop height, and spray frequency.
- Manual Knapsack Sprayer: Worn on the operator's back with a 12 to 16 liter chemical tank; operated via a continuous hand-pumping lever.
- Compression Hand Sprayer: Small 1 to 5 liter pressurized tank pumped beforehand; ideal for vegetable nurseries, greenhouses, and kitchen gardens.
- Rocker Sprayer: Heavy-duty piston unit mounted on a stable stand; operated with a rocking arm for high-reach spraying in fruit orchards and coconut trees.
- Foot Sprayer: Foot-operated piston sprayer providing high pressure for dense crop canopies and field perimeter borders.
Operating guidelines, nozzles, and calibration
Choosing the right nozzle type and pressure ensures optimal droplet size and prevents spray drift.
- Hollow Cone Nozzles: Produce fine droplets suitable for insecticides and fungicides requiring complete leaf coverage.
- Flat Fan Nozzles: Deliver a fan-shaped spray pattern with uniform droplet distribution, ideal for soil and foliar herbicide application.
- Calibrate water output with clean water before mixing chemicals to confirm correct spray volume per acre.
- Maintain steady pumping rhythm to prevent pressure fluctuations and uneven chemical dosing.
Maintenance, safety, and SMAM subsidies
Regular upkeep extends sprayer life and protects user health, while government programs assist purchase.
- Triple-rinse the tank, hose, and lance with clean water immediately after every spraying operation.
- Clean nozzle tips and filters using a soft brush or water jet; never clear blocked orifices with wire or pins.
- Subsidies available for approved manual and battery-operated knapsack sprayers under the Sub-Mission on Agricultural Mechanization (SMAM).
- Apply through the national agriculture machinery portal (agrimachinery.nic.in) or state agriculture mechanization schemes.

Common questions
Which nozzle is best for applying fungicides with a hand sprayer?
A hollow cone nozzle is best for fungicides and insecticides because it produces fine droplets that cover both upper and lower leaf surfaces.
How do I prevent clogs in manual hand sprayer nozzles?
Always strain spray mixtures through the tank inlet filter, use clean water free of suspended silt, and clean nozzle filters after every use.
Are subsidies available for manual and battery knapsack sprayers?
Yes, subsidies are provided to small, marginal, and women farmers under the Sub-Mission on Agricultural Mechanization (SMAM) and state DBT portals.
