Boxwood blight is a disease affecting plants in the family Buxaceae including boxwoods (Buxus), Pachysandra, and Sarcococca plants. First detected in the U.S. in 2011, it has since been found in multiple states and provinces from the East Coast to the West Coast. Boxwood blight has now been confirmed on boxwood nursery stock in New Hampshire. New Hampshire nurseries, landscapers, town officials and residents responsible for boxwood plantings should learn the symptoms associated with boxwood blight. Watch for black lesions on stems, "zonate" brown spots on leaves leading to chlorosis, and leaf drop. If boxwood blight is suspected on recently purchased boxwoods, or plants in proximity to recently purchased boxwoods, please contact the Division and collect a sample for analysis by the UNH Plant Diagnostic Lab.

To address mounting concerns over invasive plants and the role NHDOT activities play in the spread of these plants along roadsides, Best Management Practices (BMPs) have been developed with input from Maintenance Districts, the Roadside Development Section, the Bureau of Construction, and the NH Department of Agriculture. Implementation of these BMPs will help prevent the spread of invasive plants caused by maintenance and construction activities.

In response to the growing threat of invasive species, the Centre for Agriculture and Biosciences International (CABI) has called for urgent action to tackle the global spread of invasive species, even as the recent fall armyworm outbreak casts doubts over Africa and Asia’s preparedness to fight the scourge. The call was made at the 2018 Africa Green Revolution Forum (AGRF) in Kigali, Rwanda, by CABI’s Director General for Development, Dr Dennis Rangi. His announcement follows publication of CABI’s insights paper: Invasive Species: The hidden threat to sustainable development (PDF | 598 KB) at AGRF and this year’s launch of CABI’s Action on Invasives programme.

At its triennial Review Conference of Member Countries in Egham, UK, on 26-27 July, CABI launched a major new initiative to protect vulnerable rural communities in the fight against invasive alien species. Building on its 100-year track record in invasive species management, CABI will deliver a unique global programme to support 50 million vulnerable African and Asian farming families impacted by species that are out of control and threatening their livelihoods. This will link with, and build upon, the highly successful CABI-led Plantwise programme, which has already reached nearly 5 million farmers in 34 countries. Over the coming months and years, CABI will focus on tackling some of the worst alien invaders in Africa and Asia - weeds, insects and diseases that devastate crops and pastureland, as well as deplete the many natural resources on which rural communities rely.

CABI scientists have today warned of the impending rapid spread of the crop-devastating pest, fall armyworm, across Asia following its arrival in India, with major crop losses expected unless urgent action is taken. The warning comes following a pest alert (PDF | 42 KB) published this week by the Indian Council of Agricultural Research (ICAR) on the website of one of its bureaux, NBAIR, confirming the discovery of fall armyworm in the southern state of Karnataka. CABI scientists warned Asia was at risk from fall armyworm following the pest's rapid spread across Africa in 2017.

This interactive database contains information on the plants currently included in the Cal-IPC Invasive Plant Inventory. The Inventory categorizes plants as High, Moderate, or Limited, reflecting the level of each species' negative ecological impact in California. Includes options to search for species by region and by habitat type. The database provides a better view of information on each species and allows users to download the entire Inventory as a spreadsheet.

The goals of the California Invasive Species Action Week (CISAW) are to increase public awareness of invasive species issues and promote public participation in the fight against California's invasive species and their impacts on our natural resources.

Prevention is the most effective strategy in managing invasive species. However, hundreds of invasive plants and animals have already established in California and are rapidly spreading each year. These invaders are negatively impacting our waters, our native plants and animals (some of them rare, threatened, or endangered), our agriculture, our health, our economy, and our favorite recreational places. Help us celebrate California's Invasive Species Action Week, and more importantly, help stop the spread of invasive species, by volunteering to take action.
