The International Survey of Herbicide Resistant Weeds is a group of scientists and technical experts who are involved in a collaborative effort involving weed scientists and turf care experts from more than 80 countries. They are bringing about significant advances in science-based solutions aimed at a healthier planet for all and to educate professional lawn maintenance services of all kinds. To that end, the International Survey of Herbicide Resistant Weeds provides in-depth information about herbicide-resistant weeds through its website. It’s a thorough and concise source for everybody from homeowners with weed issues to research labs, as well as weed control and lawn care companies.

According to the Food and Water Watch, a Washington DC-based organization whose primary focus is on government and corporate accountability relating to corporate overreach, food, and water; the widespread use of glyphosate worldwide has resulted in weed control resistant superweeds that are now becoming uncontrollable. So, just what are superweeds? They’re nuisance plants that have been a significant problem around the world for many years now because they have developed a resistance to herbicides. Lawn care services around the country now have to tailor year-round lawn treatment plans that involve the use of different pre and post-emergent weed control and weed killer products to keep weeds at bay and to provide optimum turf care.

Valuable Weed Control Research

The resultant research has resulted in a far-reaching and well-defined guide for identification of herbicide-resistant weeds and weed control, including:

Herbicide Sites of Action

Diverse weed control issues over the years have resulted in scientists developing weed control products that target different mechanisms of action. These systems are thoroughly explained on this page and can give you a good insight into how the systems work and what they mean. They include the WSSA herbicide classification system, the HRAC system with 25 herbicide groups, and the Australian classification system. Lawn care services can use this information when devising a lawn treatment plan for hard to treat and common weeds.

Herbicide List & Data

If you know which herbicide you’re looking for, just click on “select by herbicide” and choose from the long list from acetochlor to vernolate. Or, maybe you only know the group you’re searching for. From ACCase inhibitors and ALS inhibitors to Z Nucleic Acid inhibitors and Z- unknowns, they’re all described in great detail on this page. Just click on “select by herbicide group.”

Herbicide Resistant Weeds By State

Although there are herbicide-resistant weeds worldwide, you’re probably only interested in those that affect your state. That’s what makes this particular page so useful. Let’s say, for example, you live or have a lawn care or weed control company in Georgia. All you have to do is move your mouse over Georgia on the map, and you’ll get a concise list of herbicide-resistant weeds.

Recent Cases of Weeds Resistant to Herbicides

Since the most recent cases of weeds found to be resistant of weed control products are the most significant, this page can be a big help, whether you’re a homeowner, a researcher, or a professional lawn care service provider. All you have to do is click on the column header for sorting by weed species or click on the country of interest, and get all of the pertinent superweed details.

Weeds Resistant to Glysophate

Glyphosate is an herbicide that was introduced in 1974 by Monsanto. EPSP synthase inhibitors (G/9) resistant weeds are listed on this page by country and species. Some of those listed from numerous states in the U.S. include weeds from Amaranthus Palmeri, (aka Palmer Amaranth) to Sorghum halepense, (aka Johnsongrass), as well as the first year they were discovered.

Weeds with Herbicide Resistant DNA

For a database that offers quick, user-friendly methods for pinpointing the most prevalent herbicide-resistant genes that affect a broad range of common weed species worldwide, this page has everything you need. And, finding the genomic DNA sequences that are responsible for encoding is easy just by clicking on a link in the table for viewing all of the details.

Herbicide Resistant Weeds By Site of Action

This page contains a comprehensive table with the number of species that have built up a resistance to a specific site of action. There are a number of species that have developed a resistance to multiple sites of action, so the total is representative of just unique resistance cases rather than the actual number of species. Just click on a column header for more info.

When it comes to yard care in general nothing is easy, and weed control resistance just complicates things big-time. This organization does a great job educating homeowners and lawn care service professionals alike, so people everywhere can have the weed-free, green lawn they’ve always dreamed of having. If you think you are dealing with herbicide-resistant weeds contact a licensed weed control and lawn fertilization company. These firms are licensed, have professional lawn spraying equipment, and can purchase commercial grade lawn treatment and weed control products that are not available to homeowners at a hardware store.
