Paperback. Condición: New. Print on Demand. This book presents the results of a series of experiments conducted by two agents of the Division of Entomology in the summer of 1885, as well as an experienced gardener engaged by the author. The aim of these experiments was to test the effectiveness of various insecticides against a…range of common insect pests, including the imported cabbage worm, Colorado potato beetle, and various species of aphids. The agents tested a variety of substances, including kerosene emulsions, salt water, soap solutions, and plant-based infusions. Their findings provide valuable insights into the efficacy of different insecticides and contribute to our understanding of insect control methods in the late 19th century. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format.
