You can remove the affected leaves, but there's no treatment that I'm aware of. Although it looks awful, it shouldn't affect the crop.
Help please!!! My lovely Buerre Hardy pear tree has blister mite ( Eriophyes pyri) I have searched for remedies, but every comment seems to suggest that I completely de-nude the tree which is drastic. Also this year the tree didn't produce any blossom. It usually flowers earlier than the apple tree, which is now in full blossom. Does anyone know what could have caused this?
An American gardening site suggested that I spray the infected leaves with a light cooking oil mixed with washing up liquid and water, does anyone know if this will help or do I have to dig up the tree and burn it, I am so desperate this is the second spring that it has become infected.
We've recently moved into a cottage which has a pear tree in the garden. This seems to be suffering from either blister mite or scab! Also there are masses of pears some of which I assume should have been removed as the branches are hanging really low with the weight. If we remove some of the pears now is it too late for the others to grow larger? We also have a large plum tree without any plums whatsoever!
The Conference pear tree in our small garden has been mildly infested during the past 2 - 3 years with the leaf blister mite, but this did not materially affect the relatively large crops of fruit, apart from a small number of mis-shapen pears. However, this year the whole tree appears to be infested and the few pears that have developed all appear to be mis-shapen and deformed. This seems to disprove comments by some experts that the fruit is not normally affected. If there are no substances available in the UK for the control of this pest, would it help if I were to drastically prune/lop the tree during the next dormant season, thus removing their overwintering sites?
