Unmanned aerial vehicle (UAV) - mediated pesticide spraying has established an efficient control system for various pathogens. However, concentrations of fungicide authorized for UAV spraying are relatively higher than for backpack spraying; therefore, unwanted dispersion of fungicides can be problematic in plots with various crops in narrow areas, such as in South Korea. In this study, we demonstrated efficient control of garlic leaf blight (Stemphylium vesicarium and Stemphylium eturmiunum) by mobile spraying equipment (MSE), which is an imitation of UAV. To select an effective fungicide for garlic leaf blight, we selected each of the most virulent strains of S. vesicarium and S. eturmiunum from pathogenicity assays for garlic with about 60% of the disease severity index. Then, we selected iprodione which showed highest control activity among 5 tested fungicides in a fungicide efficacy test using MSE and EC<SUB>50</SUB> value estimations. Iprodione solutions at different concentrations were tested to evaluate the efficacy of reduced amounts of fungicide by UAV spraying. The fungicide solution at half concentration of iprodione was sufficient to control garlic leaf blight using MSE. Our results will contribute to developing an efficient fungicide application system via spraying regulated concentrations of fungicides using UAV.
