Summary:

With record amounts of corn acreage being sprayed with fungicides and fuel at an all-time high, aerial applicators are looking for ways to quickly cover the acres required while maintaining (or improving)  the efficacy of their applications.  This field study evaluated several different aerial nozzle technologies (CP-11TT, ASC Rotary, AU5000 Rotary, and Electrostatic) at 1 and 2 GPA for best coverage in a corn canopy.  Canopy penetration was also investigated.  The study was conducted in a full size production field in Texas.  The results of this study will be used to guide aerial applicators in selection of appropriate nozzle technologies to make efficacious, low-volume applications of fungicides to corn.
