Corn (Zea mays L.) represents one of the major cash and feed grain crops in both the U.S. and the world. In 1980 in the U.S. alone over 33 million hectares of corn were planted with a cash gross value to the farmer of $20.9 billion. Scientists and commercial companies have long recognized the potential market that exists for a plant growth regulator on this large acreage crop. Yet, today there are few, if any, legitimate growth regulators being used commercially on corn.
