APPLY INSECTICIDE MATERIALS AT ONCE

List of Efficient and Dangerous Combinations Prepared by New York Station. Now that one has to fight the codling moth, the San Jose scale, canker worms, plant lice and other insects, besides the apple scab and other fungous diseases, it is advisable to apply two or three materials at the- same time. Certain materials can be mixed together with safety, while others in combination either lose their efficiency due to chemical changes, or they may prove Injurious to the tree. It is important, therefore, to know what ones can be mixed safely. The following list has been prepared at the New York experiment station: Better results are obtained by mixing parts green or arsenate of lead with bordeaux mixture than by applying them separately. a Properties are not changed by mixing lead with tobacco or bordeaux, lime sulphur with tobacco, soap with tobacco or emulsions. Efficient and nonlnjurlous are lead with lime sulphur, soap with tobacco. Inefficient, but nonlnjurlous are lime sulphur with soap, acids or emulsions. Safe and efficient triple combinations axe lime sulphur, lead and tobacco; bordeaux, lead and tobacco. Dangerous combinations are parts green with lime sulphur, soaps or emulsions; arsenate of lead with soaps, emulsions, or alkalies; emulsions with lime sulphur, zinc arsenite, or arsenite of lime with lime sulphur, soaps or emulsions; arsenate of lead or parts green, with soda or potash sulphides, soaps or emulsions.
