2023 Insect Pest Management Guide – complete book

The Insect Pest Management Guide is issued annually by the LSU AgCenter. Each edition supersedes guides for all prior years. Insecticide recommendations and rates of application listed in this guide are in conformance with U.S. Environmental Protection Agency registrations and U.S. Food and Drug Administration tolerances. Each LSU AgCenter Extension Service agent will be notified of updates as labels change. Users of this guide still should read the label on the insecticide container and follow the directions and precautions on the label carefully when using the insecticides recommended in this guide. Some insecticides registered by the U.S. Environmental Protection Agency are not included in this guide for a variety of reasons, such as their hazardous nature, lack of availability, inefficient control of pests or higher costs for use.
