I have a Bartlett pear tree that has black spots on the leaves and holes chewed on some leaves and a few curled up leaves. Could you tell me what to spray for these problems?

Your young peach tree could have suffered some winter dieback, especially if a lot of the branch tips are black. It could also have severe iron chlorosis or peach twig borer. If the latter, there are several chemicals you could use including Dipel, Sevin, Ortho Bug-B-Gone, Malathion, Concern Multi-Purpose, Ferti-Lome, Green Light, Natural Guard, or GF-120. A dormant oil spray with insecticide applied when the flower buds are swollen, but not opened is beneficial. The insecticide alone (no dormant oil added) should be applied between June 21 and 26th.
You also mentioned that the leaves are yellowing and turning brown. If the veins are a darker green color, you probably have iron chlorosis. Severe Iron chlorosis will cause the tree to die, starting at the ends of the branches. To correct this, you should watch your watering. In our alkaline clay soils, the water ties up the iron. You should also add chelated iron in the spring at leaf bud swell. By the time all the leaves are full size, adding the iron doesn't do much good.
If you brought in a sample of your branch, we could tell whether it is iron chlorosis, winter damage or twig borer. It does cost $1. and our office is open Mon-Fri 8-5. For further information, you can call us at 851-8462

- I have just moved into this new house and I have all these raspberry bushes. They have produced a crop of fruit and I went out and picked lots of berries. The berries themselves look very nice but they are a little small. When I brought them in the house I noticed a couple different kind of pests on them. A black little beetle looking bug and a little tiny bug that resembled the hair on the raspberry. I washed them off, cleaned them and ate them. Now I am all panicked that I will get sick. They tasted good but I have myself all freaked out not knowing if all the bugs got off. Will they hurt me? I want to make raspberry jam with all the berries I have. Is that safe?

- Our home was built in 1998 and we are the second owners. The first owners landscaped the yard, but didn't consider that the trees, shrubs, etc. would grow. We have trees that were planted too close to the sidewalk and shrubs that were planted too close to the house. They are beautiful, but too close. We also have a large cottonwood tree in the backyard that provides good shade, but its root are now pushing above the ground. I think I know the answer, but is there a good way to redo the landscaping without removing all of the good features at once?
