Black currants indeed found themselves under a federal ban in the United States from 1901 to 1966 due to concerns about a fungal disease called white pine blister rust. This disease, which was affecting the country’s valuable white pine trees logging industry, was thought to be spread by the black currant plant. As a result, the U.S. government banned the planting of black currants in an effort to control the spread of the disease.
However, in 1966, the ban was lifted and black currants were once again allowed to be grown in the U.S. This was due to the discovery of disease resistant varieties of black currants, as well as advances in disease management and control. Today, black currants are once again a popular crop in the U.S. and are used in a variety of products.
It is important to note that the ban on black currants was specific to the U.S. and did not affect other countries. Black currants have been widely grown and consumed in Europe for centuries, and continue to be a beloved fruit today.
