Weedkiller's nutritional boos

The benefits of so-called organic farming may be counterbalanced by the finding that application of the commonly used weedkiller's mesotrione and atrazine to sweet corn crops boosts carotenoid levels. Zeaxanthin carotenoids found in sweet corn are thought to protect the eye against macular degeneration. Now, Dean Kopsell of the University of Tennessee and colleagues there and at Auburn University, Alabama, and Illinois State University in Normal, have demonstrated that concentrations of these important nutrients might be boosted by 15% 45 days after application of weedkiller.
