AERIAL ELECTROSTATIC SPRAY SYSTEM PERFORMANCE

摘要

Production models of a USDA-developed aerial electrostatic spray application system are currently being marketed in the US and abroad. Spray deposit and insect mortality studies conducted on cotton with the USDA prototype are summarized. Spray deposits with the electrostatic system were higher than with conventional aerial application systems. The increased deposits with the electrostatic system did not always produce improved insect control. Generally, the aerial electrostatic system with a spray rate of 9.4 L/ha provided similar insect control in these studies as conventional aerial spray systems with spray rates of 46.8 L/ha or aerial ULV spray systems with spray rates of 1 L/ha. Lower spray rates contribute to improved operational efficiencies for aerial applicators
