The Weed Science Society of America is a non-profit professional society that promotes research, education, and extension outreach programs related to weeds. They don’t stop there, though–they also provide scientific research to the public as well as to policy-makers about weeds, weed control, and their impact on their surrounding environments.

The Weed Science Society of America offers two levels of membership for individuals. An individual membership can be obtained for an annual fee of $175. Students can join for $50. Both levels of membership offer extensive benefits such as reduced rates for event attendance, three peer-reviewed journals, and voting privileges. Membership to the Weed Science Society of America also provides unfettered access to resources and information regarding weed identification and lawn treatments – an invaluable resource for lawn care service professionals or even agriculture loving homeowners who just want to have a perfectly green lawn.

Valuable Research

Because of the invasive nature of weeds, staying abreast of information regarding these space-invaders can be critical towards having a truly successful lawn maintenance program. Weeds also have the capacity to weaken and stress nearby plant life, making desired horticulture more susceptible to pests and diseases. The Weed Science Society of America has up-to-the-minute information on just about every species of weed growing in this country plus a wealth of weed control and lawn treatment-related resources and information for optimum turf care.

Weed Identification and

These pages are a joint collaboration between the Weed Science Society of America and the University of Georgia’s Center for Invasive Species and Ecosystem Health. The weed identification pages offer links to common weed images to help in the identification of specific weeds. Many of the images link directly to In these pages, not only can you identify particular weeds by photos, but also browse by nodes, taxonomy, organization, location, and other specifics. When you know what weed you’re dealing with, you can then choose the appropriate weed killer or pre-emergent to use.

Composite List of Weeds

These comprehensive pages allow users to search by specific parameters using an “exact” search function. Search by common name, Latin name, Bayer code, or US code for in-depth information on individual species.

Invasive Plants

The result of a three-year project between the Weed Science Society of America and the Plant Epidemiology and Risk Analysis Laboratory (PERAL), these pages are committed to addressing noxious weed issues in the turf care industry. Here you can find fact sheets on some of the most invasive weeds in the country.

Articles About Garden Weeds

Browse through articles on weeds in this section. Read through topics from how to maintain a weed-free lawn to proper use of herbicides for abatement practices. You can also read some of the most current scholarly posts on weeds that cover topics such as roadside vegetation or aquatic weed control practices.

Poisonous Plants

There is a difference between weeds that cause mild irritations such as allergens and those that can cause serious illness or even death when ingested. These pages catalog some important poisonous plants found in North America. You may also use these pages to connect with useful resources on poisonous plants.

Herbicide Identification

This useful guide provides information on WSSA-Herbicide Site of Action classification lists as well as common and chemical names approved by WSSA. You may also browse photographs of the effects of weed control on plants: pre-emergent, post-emergent, and pre-plant applications are displayed here.

Herbicide Resistance 

Herbicide-resistant weed biotypes are becoming more common as part of a basic evolutionary process. These pages characterize new cases of resistance and explore the ways resistance is inherited. They further explore the best ways to prevent, delay, or manage herbicide resistance in weeds along with other lawn treatment-related information. Find information about lawn treatment rotations, lawn spraying advice, lawn fertilization, and more.

Allergy-Causing Plants

As previously mentioned, plants that cause allergies are different from those that are poisonous. While allergies resulting from plants may be irritating, the individual typically recovers once the allergen exposure is removed. These pages are a partial list of weeds that have been known to cause allergic reactions.

Weed Myths

Have you ever been told that spraying weeds with herbicides will create “superweeds”? Or that the best time to control dandelions is in the spring when they flower? These are some commonly-held myths about weeds. In these pages, the Weed Science Society of America lends a hand to the lawn service industry by debunking some of the most common myths about weeds and weed control.

Whether you are a homeowner trying to identify and eliminate weeds found in your backyard or you are a professional yard care service looking for professional and scientific advice about herbicides, the Weed Science Society of America offers comprehensive information for all things weed-related. These pages are perhaps one of the best resources available for cataloging and managing whatever type of weed control problem you may ever face.
