The Farmate Pressurized Manual Sprayer for Pesticides with Long Wand is a specialized tool designed for small-scale farmers, home orchardists, and gardeners who need targeted, safe pesticide application for crop protection. As the name suggests, it features a manual pressurization system (for reliable control) and an extra-long wand (70cm) —addressing two key pain points of pesticide use: difficulty reaching tall plants or dense foliage, and risk of chemical exposure from close-range spraying. As part of Farmate’s “pesticide-specific” lineup, this sprayer prioritizes chemical compatibility, leak-proof design, and user safety—critical for handling potentially harmful pesticides. Supplied as 1 unit, it includes a pesticide-resistant tank, a brass pesticide nozzle, and a residue-cleaning brush. Whether you’re treating tomato plants for aphids, apple trees for codling moths, or rose bushes for thrips, this sprayer delivers precise, long-reach pesticide application that minimizes waste and protects your health.

The sprayer’s standout feature is its 70cm stainless steel wand—longer than most manual sprayers (which typically have 40-50cm wands) and durable enough to withstand frequent use with pesticides. The extended length lets you spray tall plants (up to 3 meters) without standing on a ladder (reducing fall risks) and reach deep into dense foliage (e.g., rose bushes or orchard trees) without getting your hands close to chemicals. The wand’s tip is angled at 20 degrees, making it easy to target the undersides of leaves (where pests like spider mites hide) and the base of plant stems (for soil-applied pesticides). Unlike plastic wands that degrade with pesticide use, stainless steel resists corrosion and chemical damage—ensuring the wand lasts for 3+ years.
The 8L tank is crafted from high-grade HDPE plastic with a specialized pesticide-resistant coating—formulated to withstand corrosive agricultural pesticides (organophosphates, pyrethroids, and copper-based fungicides) that break down standard plastic tanks. The coating prevents pesticide absorption into the tank material, eliminating cross-contamination between different chemicals (e.g., switching from an insecticide to a fungicide). The 8L capacity is ideal for pesticide use: it holds enough diluted pesticide to treat 200-250 square meters of crops (e.g., a 30-tree apple orchard) without frequent refills—reducing your exposure to concentrated pesticides during refilling. A 10cm wide-mouth opening with a child-resistant twist-lock lid ensures safe filling and prevents accidental spills.
Equipped with a large, ergonomic manual pump handle, the sprayer delivers steady pressure (up to 0.9MPa) with minimal effort. A single 15-second pump session maintains pressure for 3-4 minutes—enough to spray a 50-square-meter vegetable bed without re-pumping. The pump features a pressure safety valve that releases excess pressure if levels exceed 1.1MPa, protecting the tank from damage and preventing accidental chemical spills. The handle’s rubber grip is non-slip (even when wet with pesticide residue) and absorbs shock, reducing hand strain during long spraying sessions (e.g., treating an entire orchard). For users who prefer manual control (over electric sprayers that risk battery failure mid-task), this system ensures reliable performance in any weather.
Farmers with 200-300 square-meter vegetable plots (tomatoes, cabbage, peppers) will rely on this sprayer’s precision and long reach. The 70cm wand reaches the tops of 2-meter-tall tomato stakes, and the pesticide-resistant tank safely holds vegetable-specific insecticides (e.g., spinosad for caterpillars). The manual pressure system ensures even application of herbicides to cabbage rows, preventing weed competition without damaging crops. For organic vegetable growers, the tank is compatible with natural pesticides like neem oil—no risk of chemical leaching into edible produce.
Orchardists with 20-50 small trees (apple, peach, pear) will benefit from the sprayer’s long wand and chemical compatibility. The angled wand tip reaches the undersides of apple tree leaves (targeting apple maggots) and the base of peach tree trunks (preventing borers). The 8L tank covers 30-35 trees per fill, so you won’t need to carry a heavy tank up and down ladders. The pesticide-resistant coating withstands orchard fungicides like lime sulfur (used to prevent peach leaf curl), ensuring the tank remains intact season after season.
Cleaning is critical for safety and sprayer longevity:
• Drain any remaining pesticide into a labeled container (for future use).
• Fill the tank with 4L of clean water, add 100ml of agricultural tank cleaner (or mild dish soap), and pump to build pressure.
• Spray the soapy water through the wand for 2 minutes (to rinse the hose and nozzle).
• Drain the tank, refill with 4L of clean water, and spray for another 2 minutes.
• Remove the nozzle, rinse it under running water, and use the included brush to clear any residue.
For persistent residue (e.g., dried copper fungicide), soak the nozzle in vinegar for 10 minutes before rinsing.
Yes— the 70cm stainless steel wand uses a standard 1/4-inch thread, so you can replace it with any compatible wand (sold by Farmate or hardware stores). To replace: twist the old wand counterclockwise to remove it from the tank, align the new wand’s threads, and twist clockwise until tight (hand-tight is sufficient). The wand is covered by a 2-year warranty, so contact Farmate for a replacement if it bends or breaks under normal use.
In optimal conditions (full pressure, calm weather), the wand’s stream mode reaches up to 5 meters—enough to spray the tops of 3-meter-tall trees without a ladder. The mist mode covers a 1.2-meter-wide swath at 2 meters distance, ideal for broad coverage on vegetable beds. Windy conditions may reduce stream distance to 3-4 meters, so we recommend spraying in calm weather or adjusting your position to get closer to the target.
Yes— the pesticide-resistant tank and stainless steel wand are designed to handle highly concentrated pesticides (up to 50% active ingredient). The wide-mouth opening lets you dilute concentrated chemicals safely (use gloves and eye protection), and the child-resistant lid prevents accidental spills. Always follow the pesticide manufacturer’s dilution instructions, and never exceed the tank’s 8L capacity (leave 1L of air space for pressure).
