Organic corn producers work under a different set of constraints due to the standards set by the USDA and their local organic certifying agency to be certified organic. The information and experience base for organic production is considerably smaller than that for conventional corn production. Four farms participated in a project to look at pest management concerns for organic corn producers. Fields on these farms were scouted on a weekly basis during the summer of 2006 for insect, disease and weed pests. Weed control was affected to a large degree by cultivation, previous weed problems and crop rotation. Early and more frequent cultivation and corn planted in fields that have been hay for many years appear to reduce weed problems. However long-term grass hay fields planted to corn may be more problematic as insect pests such as grubs and wireworms are more likely to be present.
