Hundreds of Midwest farmers are complaining of damage to their crops allegedly caused by the herbicide dicamba. The total number of damaged acres may come to more than 2.5 million acres, according to data compiled by a University of Missouri researcher.

Most of the damage has been found in the Midwest and South, with complaints of more than 850,000 damaged acres in Arkansas and more than 300,000 damaged acres in both Missouri and Illinois.

In the global debate over neonicotinoid pesticides, the company that makes most of them has relied on one primary argument to defend its product: The evidence that these chemicals, commonly called "neonics," are harmful to bees has been gathered in artificial conditions, force-feeding bees in the laboratory, rather than in the real world of farm fields.

Insecticides are used by both farmers and home gardeners to kill bugs.

  1. What are pesticides, actually?
  2. How are they used on my food?

From foodies to farmers, pesticides are a sensitive subject.
