Much the same condition obtains in New Jersey, according to Doctor John B. Smith. He states that the moths of the peach-tree borer emerge in greatest numbers from about June 15th to September 15th. PREVENTIVE AND REMEDIAL MEASURES Very many remedies and preventives have been proposed during the past one hundred or more years for control of this pest, and a great diversity of opinion prevails as to their relative value. Control measures which, in the hands of some individuals have given excellent results, have, in the hands of others, been unsatisfactory or failures, owing possibly to differences in climate, mode of application, or other conditions. Of the numerous preventive measures which have been proposed, perhaps mounding the earth around the base of the tree has given as good results as any. Slingerland found in New York State that from one-half to seven-tenths of the borers were kept out of the trees by this practice, and he considers it one of the cheapest and most effective of numerous methods tested by him.
