Brazil spray technology cuts agchem use by 90%

Brazilian-developed spray technology cuts pesticide applications by over 90%, according to an industry assessment. The conclusion came from B & D Equipamentos Agricolas, which tested the electrostatic spray equipment on whitefly controls in greenhouses of the Kiara foods company. The agricultural research corporation, the Embrapa, developed the technology. It has recently signed a deal with B & D for the marketing of the tool. The company explains that electrostatic attraction of pesticides affords improved efficacy: the product has an opposite electrical charge to the plant, causing greater adhesion in hard to reach areas, such as the underside of leaves. A patent application was filed in 2013: Embrapa’s “electrostatic pneumatic nozzle” produces one of the greatest electrification drop loads ever recorded for this type of equipment.
