This guide provides photographs and descriptions of biological control (or biocontrol) agents of insect, disease, and weed pests in North America. It is also a tutorial on the concept and practice of biological control and integrated pest management (IPM). Whether you are an educator, a commercial grower, a student, a researcher, a land manager, or an extension or regulatory agent, we hope you will find this information useful.

Japanese stiltgrass (Microstegium vimineum), also called Nepalese browntop, is an aggressive invader of forest lands throughout the eastern United States. Infestations can impact the diversity of native species, reduce wildlife habitat, and disrupt important ecosystem functions. Stiltgrass is considered one of the most damaging invasive plant species in the United States. Infestations spread rapidly and the seed can remain viable in the soil for up to five years. Correct identification is necessary before beginning any management activities. Fortunately, Japanese stiltgrass has a unique combination of characteristics that make field identification possible. This publication gives simple descriptions and clear pictures of these characteristics along with details on how to distinguish several common look-a-like species. Download the full PDF version of Field Guide to The Identification of Japanese Stiltgrass with comparisons to other look-a-like species, ANR – 1457 (PDF | 16.1 MB).

This guide is intended to assist with identification of invasive plants and provide information on controlling these problem plants. Included are both non-chemical means of control as well as information on proper use of herbicides where chemical controls are needed. The choice of control measure depends on the size and nature of the infestation. If dealt with early enough, invasive plant problems can often be eliminated by non-chemical methods. However, a herbicide-based approach may be required to control an infestation that has become well established or widespread.

The Weed Control Guide, a joint publication from the Cooperative Extension Services in Ohio, Indiana, and Illinois, explains the importance of weed control and gives suggestions on herbicide management strategies for corn, popcorn, sweet corn, soybeans, small grains, and forages.

This handbook is intended as a ready reference guide to the control and management tactics for the more important plant diseases in the Pacific Northwest. The specific cultural, biological, and chemical recommendations are intended to manage a specific plant disease but may not always be appropriate under all production circumstances. The synthesis of a specific management recommendation should be done by a qualified individual. For this reason, this book should be used by—and has been expressly written for—county Extension agents, consultants, field and nursery people, and chemical industry representatives. Information in this publication is in a state of constant change.
