The first definition means that all but 26 of the 600 plus crops produced in the United States are minor crops. EPA will consider every crop in the United States to be a minor crop, except for almond, apple, barley, canola, carrot, corn (field and swee t), cotton, grapes, hay (alfalfa and other), lettuce, oats, oranges, peanuts, pecans, popcorn, rice, rye, snapbean, sorghum, soybean, sugarcane, sugarbeets, tobacco, tomatoes, sunflower, and wheat.

EPA has a liberal definition of what constitutes a minor use on a major crop. According to EPA, if the incremental cost of registering the pesticide for a site is greater or equal to the gross revenue for a year of sales on that specific site it will q ualify as a minor use. For example, if it will cost $400,000 to register a pesticide on a crop such as wheat, and the estimated sales of the pesticide for one year are $400,000 or less, the use pattern would be considered a minor use and qualify for a wid e array of regulatory assistance (and support from the IR-4 program).
