Abstract

Corn, Zea mays L. is the most widely produced feed grain in the United States and accounted for nearly 95% of total feed grain production in 2017. Using conventional hydraulic and electrostatically charged nozzles and rotary atomizers, pyraclostrobin fungicide was aerially applied at 10 and 19 L/ha on VT stage corn. Fluorescent dye deposits on an artificial sampler and corn foliage were measured and quantitated using fluorometric analysis. Image analysis described spray droplets captured on water sensitive papers (WSP). The AU5000 rotary atomizers at 19 L/ha produced significantly greater deposits on artificial collectors compared to other application methods in both top and mid canopy regions. Similarly, deposition on corn leaves was significantly greater for the AU5000 rotary atomizer than that for the other delivery systems, except in the mid canopy where deposition was comparable to the hydraulic nozzle. Droplet density, % coverage and the spray rate were also significantly higher for the AU5000 rotary atomizer on WSPs. The aerial application of fungicides with AU5000 rotary atomizers at 19 L/ha and a volume median diameter ~ 255 µm significantly improved fungicide deposition on corn. These results provide guidance to aerial applicators for increased fungicide applications on corn foliage.
