In recent years cucurbit growers in the Mid-Atlantic U.S. could purchase their seeds pre-treated with the neonicotinoid insecticide thiamethoxam. The insecticide seed treatment is currently packaged as FarMore F1400, which also includes three proven and complementary fungicides that provide the first line of defense against several key seed and seedling diseases including Rhizoctonia, Fusarium, Pythium, general damping-off and seedling blight. The seed treatment is relatively cheap (less than $1 per acre), and has become widely used by growers. However, as the use of neonicotinoids have become controversial, particularly as it relates to pollinator protection issues, some growers have asked whether the thiamethoxam is really needed. In this bulletin, we hope to provide some information that might be helpful to answering that question.
