Evaluation of Electrostatic Spraying Equipment in a Greenhouse Pepper Crop

Greenhouse vegetable production is of great importance in southern Europe. It a cultivation system characterised by high planting density and environmental conditions that favour the development pests diseases. Although alternatives to chemical pest disease control have been used over recent years greenhouse crops, it still mostly plant protection products are protect crops prevent crop losses. Hand-held spraying equipment mainly apply this type crop. This technologically basic, offering low deposition efficiency canopy, losses ground, risk worker exposure. In context, important utilise technologies reduce problems associated with using conventional hand-held sprayers greenhouses. study evaluated uniformity canopy ground when applying an electrostatic sprayer; results were then compared applications carried out sprayer. For purpose, colorimetric method has based on application tartrazine solution. The tests showed increased 1.48 times spray gun, resulting 48% reduction rate. There was also 1.78-times increase underside leaves 36.36% ground. general, sprayer improves effectiveness reduces gun commonly control.
