Summary
Fireblight bacteria have been isolated from pear flowers on a selective medium and their occurrence has been correlated with weather. By averaging daily maximum and minimum temperatures, pear growers can now more accurately predict the presence of fireblight bacteria and apply pesticide sprays only as necessary.
