ELECTROSTATIC DUSTER Definitive model ready for the market after several years of studies and research with the experimental model awarded as TECHNICAL INNOVATION at E.I.M.A. 2004. TWO practical experiments, one performed in 2003 by the Experimental Institute for Agricultural Machinery (I.S.M.A.) of Monterotondo (ROME) and the other in 2007 by the Department for Agri-food Protection and Enhancement (University of BOLOGNA) have ascertained that the ELECTROSTATIC effect leads to a 29-32% increase in SULPHUR deposits on the vegetation (equivalent to the obtainable useful dose reduction), thereby drastically and visibly reducing the enormous amount of product that conventional powder applications lose in the environment. Since ORGANIC agriculture, while not using chemical molecules, must respect DISCIPLINARY rules that are more and more restrictive as far as doses/ha/year also for natural products (such as copper, sulphur, etc.) are concerned, together with the need to minimise the release of pesticides to the environment, which increasingly hangs over the agricultural world, the importance of the latest innovative contribution of MARTIGNANI stands out quite clearly

OPERATING PRINCIPLE The equipment, mounted (or semi-mounted), by the hydraulic lifter, apart from the 260-litre powder tank (in STAINLESS steel) for 200 kg of product, also has a pure water 100-litre tank for the following reason: at the outlet of the 2 OPENINGS dispensing the powder carried by the air flow of the high-performance centrifugal fan (4200 m3/h), there are two micronising NOZZLES supplied by an electric micropump which emit an ULTRA LOW VOLUME (from 10 to 20 l/ha) of atomised water. The presence, in the same point, of the high-voltage electrode at very low amperage of the MARTIGNANI...

It can work in the MOUNTED, SEMI-MOUNTED and TRAILED version It can be fitted with the vineyard spray head for PERGOLA or AWNING PLANTS easily interchangeable with the spray head for ESPALIERS 3 t can also use GUN type spray heads for I wide spraying swath treatments on low plant in OPEN FIELDS, under TUNNELS, GREENHOUSES, etc.
