INNOVATIVE TECHNOLOGIES FOR THE APPLICATION IN VINEYARDS AND ORCHARDS OF SPRAYING TREATMENTS WITH REDUCED IMPACT ON THE ENVIRONMENT. PRESENT AND PERSPECTIVES

The paper presents an analysis of the innovative technologies that are currently implementing spraying treatments with the reduction of specific consumption of pesticides, fuel, labour and especially the reduction of environmental pollution. They are presented for the administration of insecticides-fungicides and liquid fertilizers with machines for spraying vines and orchards of the carried type with a tank of 300-600 litres and of the trailed type with a tank of 600-2000 litres, which have standard fans or a tower with controlled spraying, 600-800 mm propellers with adjustable pitch, hot-dip galvanized metal parts, bronze nozzle holder, cardan shaft, etc. The work concludes with the recommendation of using an innovative spraying machine that allows significant savings of active substance, depending on the vegetative phase of the plantation at the time of spraying compared to conventional treatment.
