Abstract
Eighteen seed treatments and a non-treated control were evaluated at 16 locations in 2012 using the sweet corn hybrid, Super Sweet Jubilee (sh2). The seed treatments included registered and experimental fungicides, and one organic fungicide. Some treatments included seed enhancements, including one organic product, and insecticides. Treatments were evaluated for their effect on seedling stand and vigor. The two organic treatments resulted in significantly smaller stand counts and lower vigor ratings compared to conventional seed treatments at most locations. The organic fungicide, Champ Formula 2, slightly improved stands compared to the non-treated control at many locations, especially when tested in colder environments. The results from the other organic treatment were comparable to the non-treated control. All of the conventional treatments had stand counts and vigor ratings that were similar to the two industry standard seed treatment mixtures in the trial. Several products were shown to be equivalent substitutes for components of seed treatment mixtures for sweet corn.
