NEWARK, DEL. Defoliation of shade trees by gypsy moths and other leaf-feeding insects isn’t usually considered a serious problem, says University of Delaware extension horticulturist Charles Dunham. When trees lose their leaves early in the season, they soon put out new ones, he says. But foliage loss does reduce growth. It also affects flower and fruit bud formation. The problem is more serious when defoliation occurs two or three years in a row. If a tree is under another stress as well—such as - drought—it may go into a general decline. When that hap pens, dieback and even death may result, says Dunham. Defoliation is a more serious problem with evergreens like pines which can’t replace lost needles, so it should be prevented if at all possible. Injury to evergreens is directly related to the extent of needle loss. There are a number of ways to minimize the effects of defoliation on deciduous trees, says Dunham. Basically, these involve reducing other' stress factors and en couraging rapig generation of new leaves. At Hamilton Bank, we still make house calls. One of the biggest advantages Hamilton Bank can offer you is personal service - local contact through local offices. We have 63 offices throughout Southcentral Pennsylvania farm areas. So there’s one close to you. You probably know your local Hamilton Bank manager. He’s a neighbor, a friend. And when you need his help, he’s willing to come to you.

This is especially important during periods of dry weather. Apply enough water to soak soil in the root zone to a depth of 12 to 18 inches. This means putting on about a gallon of water for each square foot of soil area under the tree canopy. Water every two weeks until leaves are fully developed. Take care to prevent runoff, so that what you put on soaks into the ground. Regrowth of leaves can be hastened and stimulated by feeding trees with a fertilizer high in nitrogen. This is especially important for valuable or namentals and tres weakened by other stress factors in addition to defoliation. For rapid response, apply the fertilizer either in liquid form to the root system, or as a foliar spray to developing leaves. To root feed, dissolve soluble fertilizers like 20-20-20 or 30-10-10 in water and apply them with a root feeder in the area under the tree canopy. Use a rate of 2 pounds of fertilizer for 100 gallons of water. Apply 5 gallons of solution for each inch of trunk diameter. Do this as soon as possible after defoliation. come out to your house, sit down, and work right along with you to take care of any problems or questions you may have. He knows his business, he understands farming, and he’s backed up by a seasoned Agri-Finance Department. So when you have a question about banking, just call your friend at Hamilton Bank. He still makes house calls. Expanding young leaves have a high capacity for nutrient ab sorption, says Dunham. Special mixtures that contain nitrogen in the form of urea are required for foliar feeding. These spray feed formulations may have ratios like 30-10-10. Dissolve them at the rate of 2 pounds of fertilizer per 100 gallons of water, and apply to leaves and branches as a spray to Chester Co. milk promotion AVONDALE Today a milk promotion is scheduled to take place at the Avondale Grange in conjunction with the tricentennial celebration being held all day in Avondale. The Chester County Milk Promotion Committee is sponsoring the milk promotion, and it will get under way at 10 a.m. and run until 3 p.m. On hand for the celebration will be a live Jersey cow and calf, also a cow of uncertain origins and a HAMILTON BANK Lancaster Firming, Saturday, May 21,1983—€ the point of runoff. Apply when new leaves are about half ex panded. Repeat once or twice as needed. Trees which are in active, vigorous growth at the time of defoliation will suffer less than those which are already under stress from other causes, says Dunham. different color, a pink cow! Persons attending the event will be given the opportunity to test their knowledge of dairy science, by taking a brief quiz. Anyone who answers the questions correctly will be given a coupon for a discount at Landhope Farm dairy stores. Cheese and butter samples will be given away, so don’t miss the fun, get out today for the celebration.

(Continued from Page C 2) technical committee for the Northeast Agricultural Ex periment Station black fly regional project. The committee meets once a year to evaluate research findings from the different states and set a course for future research. By collecting as much information as they can on the biology and distribution of this insect, identifying as many species as possible, evaluating its impact on humans, domestic animals and wildlife, studying its population dynamics and developing methods for rearing it in the laboratroy, the group hopes in time to develop safe, effective controls for the black fly. At present there are no effective insecticides cleared for use against it. Although none of the states participating in the project has instituted an organized black fly control program. Lake says one material - a strain of the biologic insecticide Bacillus thuringiensis called israelensis (BTI) - shows great promise on black fly larvae. Though the material has not been registered for black fly control, it has been shown to have little ad verse effect on other aquatic in sects or invertebrates. (One of the few other'organisms it does kill is the mosquito larva - in fact, Lake and fellow researchers at the University of Delaware are testing BTI for that use.) Until an effective control program is available for black flies, people who plan to be out doors where this pest is active will have to seek relief from attack with an insect repellent, the en tomologist says. To speed local research efforts. Lake asks Delaware residents troubled with black flies this spring to call him at 738-2526.
