Paperback. Condizione: New. Print on Demand. This book explores the field evaluation of insecticides for the control of the alfalfa weevil in Maryland from 1962 to 1966. Faced with a growing resistance of the alfalfa weevil to heptachlor, the author tested various insecticides to find more effective chemical protection for the crop in early spring. The author provides a detailed account of the methods used, the results obtained, and the challenges encountered in the search for effective weevil control. The book offers valuable insights into the complexities of pest control, the evolution of insect resistance, and the importance of ongoing research in agricultural practices. It highlights the need for a multifaceted approach to pest management, combining chemical control with other strategies such as cultural practices and biological control. By documenting the challenges and successes of this particular study, this book contributes to the broader understanding of insect pest management and the development of sustainable agricultural practices. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format.
