The world’s largest seed company may be seeing some resistance to one of its product by a very small pest.
The U.S. Environmental Protection Agency released a report last week that said Monsanto’s genetically engineered corn may be losing some of its effectiveness against rootworms and a plan should be implemented for “suspected resistance.”
Fields in Iowa, Illinois, Minnesota and Nebraska are suspected of developing tolerance to the plants’ insecticide, based on cases of severe crop damage, the EPA said in a memo. Monsanto’s program for monitoring this resistance is “inadequate,” the memo said.
Monsanto Company said that it continues to take reports on the performance of its corn rootworm products seriously and remains committed to working with farmers to encourage the adoption of integrated pest management practices when managing high rootworm populations on farm.
