Failing fungicides force rapid revisions of apple disease control programs used by farmers in eastern United States CALS Impact Statement uri icon

abstract

  • Because a fungal disease of apples has become resistant to many fungicides, apple growers needed to change quickly to new fungicide programs or risk losing their entire apple crop. By blanketing the eastern apple-producing areas of the United States and Canada with information on how to adjust apple scab control programs, major losses were averted in most orchards.
