Kansas Crop Improvement Association is reminding farmers to make sure wheat seed transactions are legal.

Seed companies have started exercising their rights to pursue farmers who sell wheat seed illegally. They also can pursue purchasers of illegal seed and request that they destroy fields planted with the seed.

Farmers are encouraged to purchase certified seed from approved seed companies. An accompanying blue label verifies its legality.

Seed grown from legally purchased certified seed may be saved for future crops, but it is illegal to sell the seed to other farmers.
