I have a long established pear tree in my garden- it was here when I moved in 10 years ago.
It was badly neglected and overgrew a path, so I gave it a trim and a trellis to grow against. For a couple of years it bore some good fruit, but then went into decline. Every spring it would grow nicely, and be green, and then the leaves would get some kind of bug or mite and curl. The fruit, if any, would be scarred and not very appetising. I tried various things over the years, and ended up cutting the whole thing back to the trunk on a kind of “kill or cure” idea. This also enabled me to train it against the wall, solving the path problem.
Last year, I had no pest problem, but no flowers or fruit either. This year looked really good, with good growth, and lots of flowers. However, there are signs of the pest again.
Pictures follow after the cut.
I’ve looked in books and online, but have yet to find something that looks like this.
At the moment I am treating it by spraying with a mild soap solution, as I suspect it is some kind of insect or aphid, but any advice would be appreciated.
