The herbicide dicamba is thought to have been the culprit in more than 3 million acres of damaged soybeans across the country, destroying plants and leaving farmers out millions of dollars in crops.

The chemical has been in use for decades, so why is it today apparently causing farms so much damage?

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.

The Missouri Department of Agriculture announced a temporary ban on the sale of agricultural products containing the pesticide dicamba on Friday, following a similar step by regulators in Arkansas.

A senior scientist at the U.S. Department of Agriculture filed a whistleblower complaint on Wednesday accusing the federal agency of suppressing research findings that could call into question the use of a popular pesticide class that is a revenue powerhouse for the agrichemical industry.

Pesticide pollution in American streams has dropped over the last 20 years according to a new report from the U.S. Geological Survey, but scientists say aquatic life is still at risk.

Changes in regulation and the development of less toxic herbicides and insecticides have reduced the risk pesticide pollution poses to humans. However, the pesticide levels in some regions were high enough to cause harm to plants and animals that live in streams.

A fast spreading, crop destroying weed may be coming to the farms near you.

Palmer amaranth, which has plagued southern farms for decades, has been marching across the Midwest. It can decimate a crop. It can withstand many common herbicides. And it can cost farmers millions.

Roger Hargrafen, a farmer in Muscatine County, Iowa, is on the front lines in the battle against Palmer amaranth. His is one of four Iowa farms confirmed as having it.

Michael Swoyer from the Kansas City Health Department receives a lot of calls from residents with bedbugs.

Unfortunately, he says there's not much the city can do to help them — exterminating bedbugs is a time-consuming and expensive business.

So, Swoyer and the Kansas City Health Department are organizing classes for the general public on how to prevent rats, mice and bedbugs from colonizing in homes – and what people should do if they’re already there.

This summer, officials in Iowa have been asking farmers to voluntarily reduce the amount of fertilizer they use. That’s because the fertilizer contains nitrates that are being washed into state waterways and creating environmental concerns locally and nationally. The runoff has been particularly bad this year, and the outcry over typical crop practices is growing.

"Organic" has been the buzzword in produce for years, but not everyone has the budget to buy only fruit and vegetables with that certification.

Salina, KS – Atrazine is one of the most widely used weed-killers in the country. But farm fields aren't the only place the chemical is commonly found. It's also the most widely-detected pesticide in drinking water, especially in the Midwest. With some environmental groups calling for a ban on Atrazine, the Environmental Protection Agency is currently re-evaluating its safety. Kansas Public Radio's Bryan Thomspon reports.

 

Rich Hill, Mo. – March is typically when the outdoor planting season starts for Amish and Mennonite farmers in Missouri. But this year, many of these farmers may be exploring ways to farm using more environmentally-conscious methods. KCUR's Alex Smith reports.
