Management of Sclerotinia stem rot in soybeans with fungicides is limited by the difficulty of achieving satisfactory fungicide deposition to the interior of the canopy where infections begin. This project is the second year of a 3-year study to improve fungicide performance by optimizing spray deposition to the interior of the soybean canopy. Field trials utilizing boom-mounted nozzles and drop nozzles will be conducted to quantify the impact of nozzle placement, droplet size, spray pattern, application pressure, water volume, boom height, and adjuvants on spray deposition within the canopy, Sclerotinia control, soybean yield and quality, and sclerotia contamination of grain. Field trials...
