J.R. Simplot Co. and Lamb Weston have informed potato growers in Idaho that they will not be accepting produce that has been treated with Bayer CropScience's Luna Tranquility.
A spokesman for Simplot explained that the decision was based on the fact that Japan, which buys Simplot products, had not yet accepted a maximum residue limit for the newly released treatment.
Lamb Weston also released a statement that said it was conducting its own trials with Luna Tranquillity and would be seeking to establish residue limits with Pacific Rim trading partners.
