Show che:,iical will control borers Pacadichlorohenzene is something more than a hard uame to pronounce, it's u chemical that is very valuable tn controlling borers in peacli trees and may be used effectively and efficiently effi-ciently at little cost. "Thousands of pounds of this chemical chem-ical are being used each year to control con-trol peach-tree borers." says C. h BraunoH, extension entomologist at the North Carolina State college. "If the material Is applied according to directions governing its use it will give from SX) to 100 per cent control. It must be applied each year regularly. P-benzene can be used on trees four years of age and older with safety, states Mr. Branuo.i. However, if the trees two and three years of age are badly infested, one-half an ounce can be used with slight injury to the tree. For trees four and five years of age Mr. Brannon recommends three-fourths three-fourths of an ounce to each tree, and for trees six years of age a full ounce of the chemical should be applied. For very old trees with large trunks one ounce and a fourth should be applied. Break the crust around the tree and smuoth off tile soil with a hoe. Get the dirt on a level above the topmost hole made by a borer because P-hen-zene is heavier than air and will not penetrate borer holes above the point of application. Mr. Brannon states also that it is necessary to scrape away the gum from the trunk and then apply the crystals in a continuous continu-ous ring about an inch wide and about an inch from the trunk. The crystals should not be placed too far from the tree and none should touch the trunk. Several shovels of dirt should then be placed over the crystals and packed In a mound with the back of the shovel. Tear down the mounds in about six weeks after application of the chemical. |
