Comparative Experiments With Various Insecticides for the San Jose Scale (Classic Reprint) - Hardcover
Synopsis
Comparative tests of common insecticides against the San Jose scale, with practical guidance
This book reports on careful field tests of many insecticides used on apple and peach trees, focusing on effectiveness, cost, and ease of use. It covers lime and sulphur mixtures, several California and Oregon washes, kerosene-based products, and soap solutions, all tested under identical orchard conditions. The results are presented as clear percentages of benefit and include notes on application timing and environmental factors that affected outcomes.
Readers will see how different treatments performed in two Illinois orchards, with emphasis on practical decisions for growers. The work explains why some formulas failed or succeeded, and it discusses how to choose treatments that balance cost, effectiveness, and ease of preparation.- How to compare insecticides on the same pest in similar orchard conditions
- The roles of timing, concentration, and weather on treatment success
- Cost analysis and practical notes for choosing washes and soaps
- Summary tables showing which options gave the best return in this study
