Seed farmers throughout the United States are complaining that biotech seeds (which are genetically altered seeds) are becoming much too expensive, resistant to weed killer, and can contaminate conventional seed crops. However, they still continue to use the seeds. But with anticompetitive practices being investigated on biotech seed companies, seed farmers may change their minds. 

"The technology has really been hyped up a lot," said Doug Gurian-Sherman, author of a 2009 study for the Union of Concerned Scientists, which concluded that yield increases have come mainly from conventional plant breeding. "Even on a shoestring, conventional breeding outperforms genetic engineering. 

Genetically altered seed is used by a majority of U.S. farmers because weeds at one time were much easier to kill with herbicides such as Roundup. Also, these biotech crops, like corn, contained genes that allowed them to "manufacture" their own insecticide meaning farmers did not have to pay money and spend time killing insects with store-bought insecticides. In addition, biotech seed companies like Monsanto have created a monopoly in the seed business, buying smaller seed businesses and selling nothing but their genetically engineered seed. Traditional seed has even become hard to find because most "crop improvements" produced by conventional plant breeding are only sold together with biotech traits. 

But with rising costs and recent resistance to herbicides, biotech seed has become less favorable and farmers are taking notice. For instance, last year, the price of biotech soybean seeds rose 24 percent while corn seed rose 32 percent. The U.S. Justice Department is investigating the anticompetitive practices of Monsanto, and Monsanto is countering by saying it plans on offering more seed options at lower prices next year.

"There just isn't competition out there," said Craig Griffieon, a farmer in Ankeny, Iowa. 

Biotech crops have grown resistant to herbicides mainly in cotton fields in the Southern United States where giant ragweed and horsetails are affecting thousands of acres. But the problem is spreading toward the midwest now as well.

As far as genetic contamination of traditional crops that are grown near biotech crops goes, farmers have testified that biotech crops have lowered the value of their conventional crops. 

"If you've got your conventional seed right next to your neighbor's [biotech] seeds, the pollen flies," said John Schmitt, a farmer from Quincy, Illinois who had to sell a third of his conventional corn for much lower prices due to genetic contamination. "It's nature."

A majority of farmers still use biotech seed also because they believe that biotech seed yields more crop at harvest, but even Monsanto doesn't argue that most of the increase in crop yields is due to traditional plant breeding. Conventional seeds produce just as well as biotech seeds, but as noted before, conventional seed is becoming harder to find. 

While biotech seed is used more so than conventional, farmers are slowly getting the picture by realizing that there aren't many benefits to genetically altered seed as opposed to conventional seed. According to the latest statistics, the amount of farms using biotech seeds only rose one percent last year, from 85 percent to 86 percent. This is the smallest increase since 2001. In Illinois specifically, the percentage of acres using biotech corn seed decreased from 84 percent to 82 percent, where soybeans reduced as well from 90 percent to 89 percent.
