This project evaluated the efficacy of a range of fungicides in glasshouse and field experiments. It also developed a simple and reliable seedling inoculation technique suitable for a breeding program and assessed the introduction of melon germplasm from the US for tolerance to gummy stem blight. Seven fungicides were evaluated for control of gummy stem blight which is a serious foliar disease in early melons grown through periods of prolonged rainfall and high humidity. Effective disease control increased the total yield and number and weight of marketable fruit and reduced premature ripening.
