At least 13 states have reported having some degree of “highly suspected” or confirmed cases of metabolic weed resistance.

The publication reviews the policy landscape governing invasive species management and identifies critical gaps in fire-prone contexts.

Receiving a donated ex-charter boat was a huge help for the youth organization Stockton Sea Scouts, said program director John Manov.

But hauling it out for maintenance to make it safe for kids, he explained, became far more expensive than originally thought because of a new invasive species of mussel.

“This is frequently mentioned as the biggest unmet need in the market at present,” Marrone says. “So, the market is wide open for bioherbicides. At the Invasive Species Corp., our approach focuses on microbes that produce complex, novel mixtures of natural product compounds that we optimize in fermentation.”

Golden mussels can reproduce quickly -- aided by the fact that they have no natural predators and are less sensitive to variability in water chemistry and temperatures, said Pam Marrone, executive chair and co-founder of the Invasive Species Corporation, a company that seeks environmentally responsible solutions to ecological threats.

The goal is to develop products featuring cocktails of metabolites, typically with one to three dominant active compounds that may be supported by weaker or synergistic ones that are not characterized or well understood.

Invasive species are widely recognised as one of the five main drivers of nature change. Yet while the other four – climate change, resource exploitation, land and sea use change, and pollution – have risen up investors’ agenda in recent years, invasive species have been largely overlooked.

We see invasive species every day, and so we’ve normalised them. And yet, I know our situation is not unique. Most people can point to an invasive plant or animal in their community. Even if they don’t yet realise it is part of a much larger, global problem.

Results from the 2025 Weed Science Society of America (WSSA) broadleaf crops weed survey highlight the need for new herbicides and alternative weed management strategies. Those needs were revealed by comparing WSSA's 2025 survey results with those obtained in 2022.

Biological invasions can alter ecosystems, yet their impacts vary across ecological contexts. Using a global meta-analysis of 775 studies (2223 effect sizes) in terrestrial systems, we show that the most consistent negative impacts are reductions in native plant diversity caused by invasive plants and increases in greenhouse gas emissions driven by both invasive plants and animals.

One year after the discovery that golden mussels had invaded the Delta, thick colonies coat boats and piers and threaten water supplies for cities and farms. Yet the state has no specific funding or plans to tackle harms in the heart of the invasion.

While biopesticides have been around for 70 years, starting with Bacillus thuringiensis bioinsecticides, they are experiencing rapid growth as the products have gotten better and more science-based and there are more restrictions on synthetic chemical pesticides.

New study outlines how biologicals are reshaping pest management; why Brazil is leading the charge, and what other markets can learn

New technologies help scientists detect and contain invasive species before they cause irreversible ecosystem damage

Water is a driving force in the American West, and today it’s at risk more than ever. Not just from overuse, not just from megadrought, but from minuscule invaders that pose a nearly unstoppable threat to the region’s rivers, lakes, dams and reservoirs.
