A new splash of campaign cash from agricultural seed-producing giant DuPont Pioneer has broken another record when it comes to all-time spending on an Oregon ballot measure.

A $4.46 million contribution from the Iowa-based company brings the amount raised to fight Measure 92 – the mandatory GMO-labeling measure – to $16.3 million, according to Oregon secretary of state financial filings.

The previous record for spending by any one side on an Oregon ballot measure was the $12.1 million spent by tobacco companies in helping defeat Measure 50 in 2007. That measure would have increased cigarette taxes to pay for children's health care.

Other significant new contributions to the No on 92 Coalition included another $468,000 from Coca-Cola and $250,000 from Kellogg.

The Yes on 92 campaign has taken in $6.6 million. The largest new single donation is $100,000 from Oregon winemaker Eric Lemelson.

Combined spending on the measure, which already represents the most spent on any Oregon ballot measure, now stands at $22.9 million.

On its website, DuPont calls itself the "world's leading developer and supplier of advanced plant genetics, agronomic support, and services to farmers."

The company was founded in 1926 by Henry A. Wallace and currently conducts business operations in 90 countries.
