This year about half of our bronze skinned Asian pears (Korean Giant, Shinko, Hosui) are covered with large dimples, so the whloe pear is bumpy. Under the dimples the flesh is hard and white. A few Shinseiki ate also afflicted. The pears are unsellable. What causes this and what can be done about it?
Most likely stink bug. It happens to both pears and apples for me.
I do see stink bugs on the pears. But I see no penetration of the skin, no little sting mark.
I had the same problem and asked a guy at NAFEX. Stink bugs is what he said. Pyrethrin is OMRI approved.
