For the week of July 26

Peach tree borer

Remember to apply the second spray for peach tree borer about Aug. 1. Apply approved formulations of Dursban to the trunks and let it puddle around the base. Treat all stone fruits and the flowering forms of those trees.

If you are going to try to get a fall crop of peas, plant them right away. Select seed varieties that are resistant to powdery mildew.

Walnut husk fly

The walnut husk fly is a close relative of the cherry fruit fly and can be a serious nuisance. It attacks the walnuts and the maggots feed in the husk. They do not damage the inside of the nut but make the shell black and the husks do not fall off. To make matters even worse, the maggots attack the peaches in the area and lay the eggs in them. This not only allows the maggots to develop in the peaches but it makes large brown areas in the flesh. The pest is controlled by spraying with Malathion on Aug. 1 and 15. Because walnut trees are so large, it is often advisable to hire a professional.
