I have a pear tree...don't know what kind as it was here when we moved in...it's quite large/mature and is absolutely LOADED with pears this year. The poor limbs are drooping. Not that the pears are any big thrill...they're usually small and hard. But I just noticed at least 3 limbs that have a whole bunch of brown and drooping leaves at the end...looking dead. And the leaf shown, top first, then underside with this dark brown mottled whatever on it. This leaf was also from near the end of a major branch. What is wrong and how do I fix it? (the last photo shows dead tree branches at the bottom edge in the center...that's a totally different tree...not related) Attachments:     |

Hello droonfang. Sorry to hear about your pear tree. It looks like it has entomosporium leaf spot. It is a fungus that overwinters as spores on fallen leaves or as mycelia within tissue. The fungi are spread by splashing raindrops or overhead irrigation. The problem is especially bad during wet weather on new plant growth. Remove and dispose of spotted leaves that are on plants and those that have fallen. Provide adequate space between plants to reduce humidity. Remove ground covers under shrubs and mulch or have bare soil instead. In the last picture, if the stems are black, then it is probably fireblight. Prune the branches back 6 inches into good wood. Dip the pruners in alcohol or a commercial disinfectant before each cut. Dispose of all infected tissue. Good luck and take care. |
