IPM for BMSB
I have two asian pear trees and two european (bartlett and comice) pear trees that all heavily cropped this year. Almost all the fruit is deeply dimpled and distorted with hard spots that make the pears unusable. As far as I can tell the damage is from the brown marmorated stink bug. I have picked and destroyed the pears and will rake and destroy all leaves at leaf fall. Please advise as to tree management strategies from here on to ensure usable fruit next year. I'd like to be as organic as possible using cultural practices but also incorporate a spray schedule to keep the pests out of my orchard. Whenever I see a stink bug it goes in a bucket of soapy water but that isn't enough! What else can/should I do to protect our fruit crop and fruit trees from these critters?
