Aphids and infections on pear trees

Aphids and infections on pear trees

I have recently planted 2 young pear trees and they seem to be doing well, but I have noticed the presence of much leaf rolling and black tipped leaves (as well as the cluster mites). I followed advice and took off all the badly affected leaves. As long as its not fire blight, do they have a good chance of surviving? Rossion, Dublin/ Glasnevin, Co Dublin Posted: 05/05/2017

This likely to be just some wind damage which turns pear foliage black. They will adapt to the conditions.

I hope you might be able to answer a question that I have. I Am attaching photos of something that has appeared all over the branches of a greenhouse Pear tree in the last week. We do have a lot of ants and woodlice in greenhouse and maybe there is a connection. Do you have any idea what these things are? peartree, Cork, Co Cork Posted: 10/04/2017

Pear trees do not need a tunnel.

The pest is horse chestnut scale, a damaging sap-sucking insect.

Spray with a suspension of 50ml of vegetable oil and 30 ml of washing up liquid in a litre of water. Or use a greenhouse insecticide until they are dead. 


Conference Pear problems

What causes hard woody bits in pear fruit? How to avoid? 220320151, Rathmins, Co Dublin Posted: 10/10/2015

Pears contain stone cells, that feel gritty.

It is part of the taste/mouth feel of the fruit.

They are less obvious if the fruit is picked as soon as ready, and it allowed to soften reasonably before eating. 



A young pear try that I purchased in Spring and planted up immediately always had droopy foliage. I assumed that was a varietal habit. However, in recent days it has developed black and brown marks on the foliage and the droop has become more prounced. I am concerned it might be fireblight as it is planted among 25 more apple, pear, plum and cherry trees. Is my diagnosis correct (see attached photo)? Will it spread? Shoud I remove the tree and burn it? The variety is William Bon Chretrien. MikeG, Galway, Co Galway Posted: 11/08/2015

There is fire blight in the country but it is not all that common. It usually only affects one or two twigs initially and it is not highly infective in Irish conditions..

It could be a root rot disease in the root ball that never allowed it to leaf out fully, and has got worse.

It's a relatively new plant and the garden centre might take a view on it.

It is unlikely to survive, 


Spraying Pear trees

I have a number of pear trees in my garden which last year showed signs of pear scab and a blackening of the leaves. I have looked in various places for a suitable spray but have been unable to locate one. I note Jeyes Fluid is recommended in some circumstances but only when trees are dormant. Is it too late to spray for this year? If not what should I use and where can I get it? (I have tried a number of garden centers but they only had insecticides).

Look for a systemic fungicide and failing that use Roseclear.


Saving an old fruit tree

A builder next door has dug up part of my border, in which there is a 250+ year old pear tree growing. He appears to have cut through half the roots to one side of the main tree trunk. What can I do to ensure the tree will not die. It still provides fruit regularly every year? 300320152, , Posted: 30/03/2015

There is nothing to be done. The tree will recover more than likely. Its stability might have been compromised, if half its root plate is gone.
