Improved nebuliser of the type that use an air current generated, for example, by one or two turbines to dispense the substance to be nebulised, characterised in that it has an oscillating deflector installed at a certain distance from the turbine that can alter the direction of the air current such that, while this current disseminates the product, a sweeping effect is generated that moves the leaves of trees to allow the product to reach the inner parts of the trees, said deflector comprising a laminar piece with an adequate size and shape that pivots about its vertical axis, as well as means for forcing and controlling said oscillatory motion.
