San Jose Scale In Jasper.

Peter Hordeman Jr., a few days ago found a young fruit tree upon his father’s farm west of town which seemed to be affected with some sort of disease, being covered with a white mold apparently. He cut off a branch of the tree and sent to Horticulturist Troop at Purdue University, receiving the following reply, which we publish for the benefit of our readers: Dear Sir: The branch which you sent me this morning is infested with the San Jose scale. This is one of the worst insect pests that has recently arrived in this country and the only thing for you to do with your trees that are badly infested as this one is, is to cut them down and burn them at once. Trees that are only slightly infested may be treated to a wash of whale oil soap or strong kerosene emulsion. The branches and trunks should be covered with this but it will not do to use it as strong on the foliage as is required on the trunk. For this purpose use twojpoundsof whale oil soap to one fallon of wi-ter, During the months of fine, July, and August, trees should be sprayed with kerosene emulsion of the ordinary strength to be used on the foliage. We mail you a copy of our sptaying bulletin so that you may see how these mixtures are made. Will you kindly inform me where you got these trees and how long they have been planted out. If you bought them of an agent, can you tell me who the agent was and what nursery he represented? This is the first time I have found this pest in Jasper county. Very respectfully yours, J. Troop, Horticulturist.
