Boxwood blight is a fungal disease that can cause the leaves of boxwood plants to fall off prematurely. ARS scientists in Fort Dietrick, MD, are studying how boxwood blight evolves and are working closely with the floriculture and nursey industry to develop methods for testing, controlling, and mitigating the disease.

Seed banks can provide insight into a forest’s past and give land managers valuable information to help them plan for the forest’s future. For example, knowing which species may germinate after future fires is valuable, especially when nonnative invasive species in the seed bank could proliferate quickly following disturbances.

In this study, researchers analyzed the species composition of buried seeds and extant vegetation present in areas that have faced differing fire conditions over many years on the Monongahela National Forest in West Virginia.

This portal shares information about how ARS research is combating the disease that is devastating the citrus industry and provides information for the general public, as well as points of contact for those seeking more specialized answers.

Huanglongbing, also known as citrus greening, poses the most serious threat that the Florida citrus industry has ever faced. ARS scientists across the country are actively engaged in research with university and industry partners on all aspects of this disease problem, including the host, pathogen, and insect vector. Our goal is to overcome citrus greening and ensure the U.S. citrus industry can provide consumers with tasty, high quality citrus fruits for years to come. 

The newly launched Vermont Forest Invasive Pest Status Map offers an interactive platform to track the spread of invasive species such as beech leaf disease, elm zigzag sawfly, elongate hemlock scale, emerald ash borer, and hemlock woolly adelgid across the state. The application provides users with a comprehensive overview of town infestations and detection years for each invasive pest.

The Alaska Aquatic Invasive Species Clearinghouse (AK Aqua) is a database and mapping application that provides temporal and geospatial information for invasive aquatic species in Alaska. Taxa profiles and associated planning documents are provided for many of the species listed in AK Aqua. These data are primarily intended to support the identification of problem species, thus promoting early detection and rapid response across Alaska. Data are also used in a variety of research and modeling activities.

The U.S. Department of Agriculture’s Animal and Plant Health Inspection Service (APHIS) has released Fruit Fly Exclusion and Detection Program Fiscal Years 2024-2028 Strategy [PDF, 1.2 MB]. APHIS worked with members of the National Plant Board to develop a unified roadmap for USDA and its partners to protect American agriculture from the threat of invasive fruit flies and measure our progress along the way.
