Karnal Bunt Status of the Mexicali Valley of Mexico

We are amending the wheat diseases regulations by recognizing a wheat-growing area within the Mexicali Valley of Mexico as being free from the wheat disease Karnal bunt. Surveys conducted by Mexican plant health authorities in that area of the Mexicali Valley since 1990 have shown the area to be free from Karnal bunt, and Mexican authorities are enforcing restrictions designed to protect the area from the introduction of Karnal bunt. This change will have the effect of removing certain restrictions on the importation into the United States of wheat seed, straw, and other wheat products from the Karnal bunt free area of the Mexicali Valley.
