Trelay has made a good faith effort to maintain the purity of the seed we market. We do not test foundation seed for the absence of GMOs, as there are no standards to meet. There are a number of difficulties presented by today's GMO dilemma. Testing to prove the absence of a trait is difficult to accomplish accurately when the target is unknown. There is no standard tolerance level established per trait.
Markets vary on required tolerance levels.
Pollen drift is uncontrollable. Problems with traits can occur after the growing season. Accuracy of the test is dependent on the sampling procedure and the sample size. Present testing is limited to very small sample sizes. Growers can take the following steps to improve their position.
