Evaluation of Drift-Reducing Nozzles for Pesticide Application in Hazelnut (Corylus avellana L.)

Spraying pesticides using air induction nozzles is a well-known method to reduce drift. These drift-reducing have been tested on many different tree crops (such as apples, citrus, and grapes), but we are still lacking information their utilization hazelnut (Corylus avellana L.) groves, although major nut crop in Italy, recent years its cultivated area has constantly growing. This paper reports comparison between treatments carried out with cone flat-fan low-drift versus two conventional nozzles. The distribution quality, the number of droplets per cm2 target area, drift non-target trees adjacent those treated were evaluated by analyzing impact water-sensitive papers placed canopies. results show that because no significative differences terms application quality found nozzles, can be good alternative standard pesticide applications hazelnuts without altering chosen pesticide.
