[nafex] Asian Pear cracking

[spiralfarm@yahoo.com]

Hello NAFEX,
I would like to find out more about the causes of cracking in Asian 
Pears and ways to minimize or prevent it. I understand that some 
varieties are more susceptible. What is your experience.
My Shinko pears have cracked more in the last 2 or 3 years. I thought 
that they looked good in the earlier years. The tree was planted in 93 
from a one year old grafted whip. I have other varieties but younger 
trees, some are cracking, some have less cracking but they are just 
starting to produce fruits. The trees have drip irrigation and 
occasionally sprinklers are turned on. They are planted in a well 
drained silty loam topsoil the subsoil is silty clay. They are 
mulched with wood chips and get a light dressing of composted manure 
in the spring. They are grown organically and get some liquid compost 
teas in early summer. I live in the West Kootenays of British Columbia 
between the Rockies and the Okanagan. This area can be very wet 
(interior wet belt) with a lot of snow in the winter but the last few 
summers have been dry. Which give us a break on fungus and cankers 
specially "anthracnose". If you're area is susceptible, has anybody  
found an "anthracnose" resistant variety of apple or pears out there? 

Thanks,
Greg Lamoureux
