摘要：
The present invention relates to a system for spraying a product, notably a plant-protection product, comprising product spray nozzles (10) and airflow generating means (110), characterized in that the airflow generating means comprise an outlet (112) in the form of an annular slit designed to generate an airflow (102) in the form of a continuous tubular curtain of air enclosing the jets (12) emanating from the spray nozzles (10) and that the sprayed product cannot cross.
