The National Corn Growers Association (NCGA) is a U.S. organization founded in 1957. It describes itself as 'a federation of state organizations, corn boards, councils and commissions developing and implementing programs and policies on a state and national level to help protect and advance the corn producer’s interests.'

Syngenta, Monsanto and others contributed about 11 percent of the National Corn Growers Association’s $7 million budget in fiscal year 2001, says spokesman Stewart Reeve.

According to South Dakota corn-growing farmer Dennis Mitchell, 'It’s a big conflict of interest when the NCGA and the Soybean Association take money from agribusiness when they’re supposed to be representing the interests of farmers.'
