Find the right sprayer for your farm at KrishiDukan. Choosing the correct spraying equipment is as important as choosing the right chemical — poor application equipment leads to uneven canopy coverage, inconsistent chemical distribution, over-application in some zones with phytotoxicity risk, under-application in others with poor pest or disease control, unnecessary chemical waste and higher operator exposure.

KrishiDukan stocks manual knapsack sprayers, battery-operated (electric) knapsack sprayers and petrol-powered knapsack sprayers across tank capacities from 10 litres to 20 litres. Each listing specifies the tank capacity and material (HDPE or stainless steel), pump type (piston or diaphragm), working pressure range, flow rate per minute, spray range (horizontal and vertical), nozzle type included (flat fan, hollow cone, adjustable), battery voltage and Ah rating plus charging time (for electric models), engine displacement and fuel consumption per hour (for petrol models), weight empty, and the types of chemicals compatible with the tank material — important since some formulations are corrosive to standard HDPE tanks.

For small plots up to 1 acre in row crops and vegetables, a 16-litre manual knapsack sprayer in the ₹800–₹1,500 range is usually adequate. The limiting factor is operator fatigue — continuous pumping over a full tank refill cycle is tiring, and variable pump pressure leads to inconsistent spray quality. For farms above 1 acre sprayed two or more times per season, a battery-operated knapsack sprayer with a 12V or 16V pump (8–12 Ah battery, 45–90 minutes run-time per charge) delivers constant pressure automatically and significantly reduces fatigue. These typically cost ₹2,500–₹6,000. Petrol-powered knapsack sprayers (2T or 4T engine, 1.5–3 HP) are the right choice for large areas, tall crops like sugarcane, banana or mango orchards, and locations where electricity for battery recharging is unavailable or unreliable.

Nozzle selection matters more than most farmers realise. Flat fan nozzles (110° or 80° angle, TeeJet or equivalent) produce a uniform flat spray pattern ideal for herbicide application and good canopy penetration for insecticide and fungicide work. Hollow cone nozzles produce a ring-shaped pattern that deposits spray on the underside of leaves — critical for fungicide programmes where downy mildew, powdery mildew or rust infections start from the abaxial leaf surface. Adjustable twist nozzles offer flexibility but sacrifice calibration accuracy, so they are better suited to irrigation-type uses than precise pesticide delivery.

Always triple-rinse the tank, pump barrel and hose with clean water immediately after each use, especially after herbicide applications — residues of 2,4-D or glyphosate left in the tank can damage sensitive crops at the next use even in very small quantities. Store the sprayer with the pump piston lightly lubricated and in an area protected from UV light and temperature extremes, which degrade HDPE tanks over time.
