They are the parents of one son. pest populations should be especially interested in dormant oil treatment, says University of Delaware extension entomolgist Frank Boys. The action of the oil is physical, not chemical. Chemical pesticides actually enter into the metabolism of an insect. Dormant oils, on the other hand, physically interfere with life support systems such as breathing and resistance to the elements. Oils must be used, though, when the plant is not in leaf, as they can injure fohage especially if they are applied to newly emerged plant material. This is why they are called dormant oils. Applied once a year during dormancy, they help reduce pest populations on many woody plants. For maximum control they need to be followed by a general chemical spray program during the growing season. Most plants become All-around worker* The Kubota LlB5 is a very accomplished tractor.

They can be treated at any time durng this period when the weather is going to remain mild with tem peratures not lower than 40 degrees for about two days after. A hard freeze immediately after oil has been applied can result in tissue bum of the bark. Fall conditions are usually most dependable for dor mant oil use, says Boys. Oil sprays can be applied even before leaf drop is complete since proper temperatures are constant then and no loss occurs from leaf bum as the foliage is falling naturally then. Spraying is also possible in late winter, but keep a close eye on weather conditions so that you don’t get caught by a sudden drop in tem perature after treatment. One word of caution-not all plants can be treated safely with dormant oils. They should be avoided on sugar and Japanese maples, beech, hickory, walnut, butternut, birch, Atlas cedar, chamaecyparis, blue spruce and Douglas fir.
