Which peaches were outlawed in 1940's?

In the 1940s, the U.S. government outlawed the cultivation of certain peach varieties, particularly the "Elberta" peach, due to concerns about fruit pest infestations and the need to control diseases such as peach leaf curl. This regulation was part of broader agricultural efforts to protect crops and maintain fruit quality. The restrictions were aimed at preventing the spread of pests that could threaten other fruit crops as well.
