Since 2005 we have performed research on multiple crops in Michigan. Those crops include Potatoes, Soybeans, Corn, Sugar Beets, Tomatoes, Wheat, Cucumber, Pepper and Blueberry(more information on diseases and nematodes below). We also run soil/root samples for nematodes at our in-house laboratory and consult on potato and wheat crops throughout Michigan, Illinois, Indiana, North Carolina and Ohio.(see map below)
