Book excerpt: Excerpt from Comparative Experiments With Various Insecticides for the San Jose Scale For this purpose, control was obtained of two small orchards near Richview, 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.

Book excerpt: Excerpt from Experiments With Insecticides for the San Jose Scale March 25; that is, twenty-two days for the first two lots, twenty days for the third and fourth, and five days for the lot under tents. The experiments consisted of a single application of the insecticide in every case, with varying subsequent treatments of the different trees with water. Frequent counts of dead and living scales were made for all of the trees, no attention being paid in these counts to old scales, outworn and dead, but only to those whose size and immature character showed that they belonged to the new generation of the preceding fall. Counts of dead and living scales were made in all cases either before or shortly after the applica tion of the insecticide spray. It was. In this way ascertained that an average of about fifty per cent. Of the immature scales were al ready dead on these trees before the insecticide was applied; and that the action of the insecticide was scarcely perceptible within the first twenty-four hours.

Book excerpt: Excerpt from Methods and Results of Field Insecticide Work Against the San Jose Scale, 1899-1902 In order that I might report the definite and final results of these experiments, I made a careful examination of every tree in the orchard on Tuesday and Wednesday of this week. Where there were hundreds and thousands of scales breeding on the trees at this time last year not one can be found now, except upon trees under 5 feet in height and on those fumigated when the foliage was wet with dew or fog or immediately after a rain, and even on these trees the young larvae are very few as compared with their number at this time last year. Where the fruit was much pitted and scarred by the scale last year not one has been seen upon a pear thus far this season. In all, the experiment is thoroughly satisfactory, in that it demonstrates by actual trial that this method can be used in our largest bearing orchards, even under the most adverse conditions, with excellent results.
