The EPA has just established tolerances for the first time for metaldehyde for corn and soybean, which will mean that molluscicides for slug control containing this product, such as Deadline MPs, should be available in the future for both corn and soybean in Ohio.
The registration of metaldehyde approved earlier this year did not have those two crops on the label, and field crop growers were faced with the removal of metaldehyde products from their tool box.
In reality, metaldehyde never had tolerances for those two crops.
However, through work of the IR-4 program, a program that helps get products labeled for minor uses or in this case, minor uses on major crops, EPA has established tolerances for metaldehyde on corn and soybean as of last week.
We will keep growers informed when we see new product labels that should list both crops.
