Publisher's Synopsis

Excerpt from Comparative Experiments With Various Insecticides for the San Jose Scale

For this purpose, control was obtained of two small orchards near Richview, Ill., both belonging to Mr. Edward Tucker, one con taining 780 apple and peach-trees badly infested in the main, and the other, 680 peach-trees infested throughout but much less heavily so. These orchards were divided into plots of varying size, those in tended for the more important insecticides containing from 47 to 141 trees each. Minor experiments were made on smaller lots, of from 3 to 33 trees, and single trees here and there were also used for a few preliminary tests.
