Corn dies young
In recent years, corn plants and entire fields in the Midwest have been dying earlier and earlier due to various diseases. Seasoned and observant farmers say they’re never seen anything like it.
“A decade ago, corn plants remained green and healthy well into September,” says Bob Streit, an agronomist in Iowa. “But over the last three years, diseases have turned the plants yellow, then brown, about 8 to 10 days earlier each season. In 2010, yellowing started around July 7th and yield losses were devastating for many growers.”
Bob and other crop experts believe that the increased use of glyphosate is the primary contributor to this disease trend. It has already reduced corn yields significantly. “If the corn dies much earlier,” says Bob, “it might collapse the corn harvest in the US, and threaten the food chain that it supports.”
A question of bugs
In addition to promoting plant diseases, which is well-established, spraying Roundup might also promote insects. That’s because many bugs seek sick plants. Scientists point out that healthy plants produce nutrients in a form that many insects cannot assimilate. Thus, farmers around the world report less insect problems among high quality, nutrient-dense crops. Weaker plants, on the other hand, create insect smorgasbords. This suggests that plants ravaged with diseases promoted by glyphosate may also attract more insects, which in turn will increase the use of toxic pesticides. More study is needed to confirm this.
