Flowering Pear trees. I have some mature "Chanticleer" flowering pears. For the last 2 years, the new foliage has emerged with curled leaves and a white, cottony substance. This condition seems to lessen with the hot weather, but the foliage doesn't seem to totally look healthy like when the trees were younger. What is it and can it be treated?

Difficult to diagnose with just that description. It could be powdery mildew from infected buds that infects newly emerging leaves.
Here is a description from PNW Online Plant Disease Management. Go to http://plant-disease.ippc.orst.edu/disease.cfm?RecordID=806 and see if this is what you have.

- My green peppers have black at the stems of almost every branch. Is there anything I can do to save them?
- Last year when I was about to harvest my corn from my yard I found that something got to about half of it before I did. I don't think it was insect because of the nature of the damage; I suspect birds. On the ears in question the husks were literally shredded and each kernel picked out. I know there are blue jays nesting in the area but this was the first time any thing like that happened. I don't think it was a mammal since the stalks were intact and not collapsed from the weight of what got at the ears that were devoured. Do you what causd this to happen? Is there something I can do to prevent that from happening this year? Thanks
- We have 2 honeylocust trees in our yard. I would guess "Imperial honeylocust". They seem to be about 15 years old or so. They are spaced about 20 feet apart. This spring one has leafed out and the other is still not budding or leafing out. Over the winter, the one that is not budding turned bright red on the trunk, which we have never seen before. The tree is getting a very few buds and leaves on some main branches (like suckers) but no buds or leaves on the outer limbs. Is there anything we can do to save this tree?
- Some of the bottom leafs on my tomato plants have turned brown and are dying. I have lost one plant and it looks like another may go soon. I am watering three to four times per week and I have been putting a liquid fertilizer on the plants about once a week. Any ideas about what I may be doing wrong?

- I want to plant raspberries in my garden next spring but am confused. Which does better in Cache Valley: summer- or fall-bearing? The USU pub on raspberry production (HG/2004-16) says plant only Haida or Malling Joy, but I haven't found anything about these species on the web. Is this statement still valid? If so, are they fall- or summer-bearing? If not, what is your species suggestion?
