BARI Foot Sprayer: Steady Pressure Spraying Without an Engine

English  ·  বাংলায় পড়ুন ↓

A foot sprayer is pumped by foot and delivers spray through a hose and lance, so one person pumps while another sprays — or the same person alternates. It gives steadier pressure than a hand-lever knapsack, costs nothing to run, and keeps working in places where fuel, spare parts and service are hours away.

Where a foot sprayer is the right tool

For small and medium plots, nurseries and vegetable beds, a foot sprayer does everything a small farm needs: insecticide and fungicide application, foliar fertiliser, and spot treatment. It is simple enough to repair locally and does not sit idle because of a fuel price or a dead engine.

If you cover large areas, tall crops or orchards, a power sprayer will be faster and reach higher. Many farms keep both: the power sprayer for the main crop, the foot sprayer for nursery and small jobs.

Spraying evenly: the part most people get wrong

• Keep pressure steady. Pump at a constant rate; pressure that rises and falls changes the dose along the row.
• Hold the lance at a constant height and walk at a steady pace. Slowing down doubles the dose in that spot.
• Choose the right nozzle for the job — a fine cone for foliage cover, a flat fan for ground-directed work.
• Calibrate. Spray a measured area with water, measure what you used, and set your mix rate from that.
• Spray in still conditions, early morning or late afternoon, to avoid drift and evaporation.

Safety is not optional

Agro-chemicals are the most dangerous thing most farms handle. Wear long sleeves, gloves and eye protection, and a mask where the label requires it. Mix outdoors, never with bare hands, and never by mouth-siphoning a hose.

Keep a separate sprayer or scrupulously washed equipment for herbicides — herbicide residue in a sprayer later used for vegetables can damage the crop. Wash yourself and your clothes after spraying, keep chemicals locked away from children and animals, and respect the pre-harvest interval on the label.

Maintenance

Rinse the tank, hose and lance with clean water after every use, and flush the nozzle — blocked or worn nozzles are the most common reason for uneven spraying. Never clear a nozzle with wire or by blowing through it with your mouth; use water and a soft brush.

Check seals, washers and the hose for leaks before each season and replace them early; a dripping sprayer wastes chemical and puts it on the operator. Store empty, clean and dry, away from sunlight.

Frequently asked questions

How is a foot sprayer different from a knapsack sprayer?

A foot sprayer is pumped by foot and delivers more consistent pressure through a hose and lance, while a knapsack is carried and hand-pumped. The foot sprayer usually gives a more even dose; the knapsack is more portable.

Can I use the same sprayer for herbicide and insecticide?

It is safer not to. Herbicide residues are difficult to remove completely and can damage crops sprayed later. Keep a dedicated sprayer for herbicides where possible.

Why is my spray uneven?

Usually inconsistent pumping, changing walking speed, or a worn or partly blocked nozzle. Check the nozzle first, then your pumping and walking rhythm.

What protective equipment is needed?

At minimum long sleeves, gloves and eye protection, plus a mask if the product label requires it. Mix outdoors, wash thoroughly afterwards, and follow the label’s pre-harvest interval.
