Abstract
This thesis explores the use of plant biostimulants among agricultural producers in the commercial Georgia blueberry industry. To contextualize this research we surveyed Georgia blueberry farmers (N=37; 1,811 ha) about their production practices; pest, disease, and weed management; agrichemical use; and perceptions about key blueberry production concerns. Survey results indicate an increase in plantings of southern highbush cultivars, irrigation use, and yield in comparison to previous years. Interviews with Georgia Blueberry Growers (N=10) indicate that there is substantial ambiguity among growers regarding the definition and efficacy of plant biostimulants. Growers draw on a wide range of information resources but put the most trust in those that are perceived as unbiased or have established expert credentials. From university-based research and Extension, they seek clarity about what plant biostimulants are and how they work, as well as an impartial review of biostimulant products on the market and the benefits they can provide.
