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 an apricot tree in my backyard that is loaded with apricots. We have not sprayed the tree with anything, but I would like to use what I can of the fruit that is not 'buggy'.
