Preventive Treatment for Pear Scab and Fireblight
My Bosc pear tree has developed a severe Scab infection. My neighbor next door has a young Bartlett pear which we understand is susceptible to Fireblight. I have read that Bordeaux Mix spray is the best organic treatment for these diseases. However, I am not finding it sold here in Coos Bay. What is the best organic treatment for our pear trees. We live uphill from the Coos River in winter zone 8b. Thank you, Cynthia Medlin
