Three months ago and Iowa State University study found that rootworms were developing a resistance to the pesticides in Monsanto’s genetically modified corn plants. Now the Environmental Protection Agency is supporting the Iowa State findings.
The EPA released a memo stating that there is evidence of resistance to the pesticides in Iowa, Illinois, Minnesota and Nebraska. In the memo, the EPA called on Monsanto to increase the monitoring of their product.
Monsanto issued a response stating that they take the findings seriously, but they do not feel there is definitive scientific evidence of rootworm resistance.
Their statement went on to recommend better management practices for farmers experiencing rootworm issues. The primary recommendation is for farmers to not continuously plant corn, but to instead switch between planting corn and soybeans every year.
Monsanto’s full statement is available here.
