Sinopsis

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.
