I have a relatively young pear tree, that is quite close to a few other fruit plants in my garden. Over the past week, small bumps have appeared along the leaves that are greeny white, but have no sign of infestation. I was told it could be a virus and to burn the leaves. However, since this began it's spread to the entire plant - should i just get rid of it before it infects my other plants, or does this sound familiar to anyone? Thanks for any help you can offer, Maria
