Farmers falling back on chemical pesticides as GMO seeds falter

Though biotech companies like Monsanto spent many millions creating and inserting genes that would make corn plants poisonous to the corn rootworm but harmless to other creatures, the pest has begun to develop an immunity.

Though the use of chemical pesticides has always been a source of contention, the advent of corn hybrid plants by biotech companies like Monsanto allowed farmers to cut back on their use. These new hybrids had been specifically designed using genes from a bacteria called Bacillus thuringiensis (Bt), which provided a formidable defense against corn rootworm.   

Throughout parts of the midwest, however, farmers are now discovering rootworms that are immune to the genetically modified corn. In parts of Illinois, Minnesota and Nebraska, where rootworm has made a comeback, farmers have now returned to using chemical pesticides.

According to Dan Steiner, an independent crop consultant in northeastern Nebraska, the return of the soil insecticides brings back bad memories.

“We used to get sick [from the chemicals],” Steiner tells NPR.

“Because we’d always dig to see how the corn’s coming along. We didn’t wear the gloves and everything, and we’d kind of puke in the middle of the day. Well, I think we were low-dosing poison on ourselves!”

According to the US Department of Agriculture,  two thirds of all corn grown in the US is of a hybrid variety, carrying the Bt gene that targets the rootworm. The first hybrids were introduced in 2003 and, as their proliferation now shows, proved to be very popular.

Though traditional pesticides may help in evening out the odds, there are other alternatives to combat rootworm despite its adaptation to the corn hybrid. Steiner, for one, has advocated “starving” the rootworm by depriving it of its food source, and advising farmers to rotate their crops from corn.

Crop rotation, however, is not likely to prove popular among farmers who take advantage of some $5 billion in government subsidies per year, doled out regardless of crop prices or yields.

Corn is by far the largest recipient of yearly crop subsidies in the US, a policy which has been sustained in part due to corn ethanol production, which critics say is not a viable energy policy, and which has kept the price of corn so low that manufacturers of processed foods in the US habitually replace sugar with high fructose corn syrup.

According to University of Nebraska entomologist Lance Meinke, the increasing use of chemical pesticides may well be nailed down to the current politics of growing corn, particularly in the face of alternatives such as crop rotation.

“I think economics are driving everything,” Meinke tells NPR.

“Corn prices have been so high the last three years, everybody is trying to protect every kernel. People are just really going for it right now, to be as profitable as they can,” he adds.

In the meantime, companies such as Syngenta and AMVAC Chemical, which produce soil insecticides for corn, have reported increases in sales of 50 to 100 per cent over the past two years.

The situation now developing with the resurgence of the corn rootworm is not unlike that being experienced by American farmers who have relied on Monsanto GMO seeds resistant to the company’s own Roundup Ready herbicide.

Some fifteen years following the introduction of the herbicide-resistant GMO seed, most of the corn, soybean and cotton cultivated in the US is now of the Roundup Ready variety.

Some 15 years later, most of the corn, soybeans and cotton cultivated in the US stems from these Roundup Ready seeds. While the genetically modified crops were meant to be resistant to application of the weed-killing Roundup herbicide, farmers are now increasingly having to deal with Roundup-resistant “superweeds.”

It is now estimated that in the period from 1996, when the GMO crops were introduced, to 2011, an additional 404 million pounds of chemical pesticides were applied to US fields, amounting to a 7 per cent increase overall.

  1. So I guess the moral of the story here is that either you’re producing your own food, or you’re eating poison.

    Chemical pesticides and herbicides are only necessary to increase the yield on mega-farms by eradicating much of the labor and time involved in pulling weeds, and using organic solutions for pest control. Small, independent farms don’t need any of that stuff.

    Your food became poisonous because you allowed the federal government to attack small, independent farmers so Kraft, Nabisco, and General Foods can operate without competition.

    Now you city dwellers who thought farm issues weren’t your problem can belly-up to a plate full of poison, and enjoy the fruits of your apathy until they kill you. Bon apetite.

  2. Almost every farmer I knew of my father’s era died of cancer. I think it was due to the pesticides they sprayed every year, plus the cancer-causing SV40 virus that infected the population through required “polio” vaccinations in the 1950s and 1960s.
