Inhaltsangabe
Excerpt from Field Evaluation of Insecticides for Control of the Alfalfa Weevil in Maryland, 1962-66<br/><br/>From 1962 to 1966, many insecticides were evaluated for chemical control of the alfalfa weevil. Most of these are still in the experimental stage, are not registered for use on alfalfa, and are no longer of interest commercially. None of the materials applied in the fall to small plots gave effective protection-partly, we now think, because of subsequent reinfestation. The material applied in early spring that showed most promise was Niagara nia  10242 (granular) at 1 pound per acre (82-percent control at harvest). Named compounds that consistently gave good control when applied to the growing crop during the Spring were azinphosethyl, azin phosmethyl, Azodrin, Imidan, methoxychlor, and phorate. Methoxychlor at 1 pounds per acre plus either diazinon or malathion at 1 pound per acre were the only combinations tested more than 1 year that gave consistently good results. The outstanding numbered insecticides evaluated more than 1 year included American Cyanamid e.i. 47772, Bay 25141 and 39007, Chipman rp-11974, Geigy gs-13005, General Chemical CC-6506, Hercules 14503, Shell sd-7438, and Virginia Carolina VC 3-670.

Paperback. Zustand: 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.
