In recent years the Ontario Invasive Plant Council has developed Best Management Practices (BMPs) guides for more than 15 different invasive plants in Ontario. The BMPs provide you with a detailed background history on the plant, how to identify it and how to properly manage it. The series promotes the use of integrated pest management to achieve effective control.

Owners of ash trees are faced with some potentially big decisions about how to protect their trees against the destruction of emerald ash borer. Although there is no perfect solution, insecticides are available to protect high-value trees. To help Iowans better understand their options, a group of specialists with Iowa State University Extension and Outreach recently published a guide called "Emerald Ash Borer Management Options." In this four-page resource, the specialists explain how to determine the value of ash trees, the cost of treatment and how to compare the different treatment options available.

After 12 years of research, a parasitic wasp that controls a highly destructive fruit fly will be released by Oregon State University agricultural scientists in June. Vaughn Walton, Extension entomologist and professor in the College of Agricultural Sciences, said the U.S. Department of Agriculture has permitted release of the wasp (Ganaspis brasiliensis), a slow process that took more than 10 years from application to decision. Now that it has a permit, Walton’s lab, which is part of the OSU Agricultural Experiment Station, is raising enough wasps to make a dent in the spotted wing drosophila (SWD) population in Oregon.

On July 1, 2019, a new law (RSA 487:43) went into effect, requiring all persons operating a motorboat that is registered in another state (other than New Hampshire) on New Hampshire public waters, to display a New Hampshire aquatic invasive species decal from the Department of Environmental Services.

We need your help to "outsmart" invasive species in Massachusetts. If you have a smartphone or a digital camera, the power to protect the natural heritage of Massachusetts is already in your hands. Join the Outsmart Invasive Species Project to help stop the spread of non-native plants and insects that threaten our environment.

Plant Pest and Quarantine executives and trading partners from 13 Pacific Island countries are in Fiji this week to investigate ways to better prevent and control the introduction and spread of plant pests and diseases across country borders. To address such global issues, the International Plant Protection Convention (IPPC) has drafted International Standard Phytosanitary Measures (ISPM) which have been reviewed by countries, including the Pacific countries attending the three-day Regional International Plant Protection Convention (IPPC) Workshop which concluded yesterday.

The Pacific Islands Marine Bioinvasions Alert Network (PacMAN) Project, which aims to monitor and identify marine biological invasive alien species, was officially inaugurated on November 24 in collaboration with the Institute of Applied Sciences at The University of the South Pacific (USP-IAS).

USP-IAS Acting Director, Dr Isoa Korovulavula stated it was a significant occasion as they moved collaboratively to a new "frontier" of protecting the local marine environment from invasive species. "The PacMAN Project is expected to boost local capability for early identification and warning of maritime invasive alien species. We are using revolutionary technology, such as DNA metabarcoding, to identify and deal with marine invasive alien species in our local marine environment," he explained.

This handbook is intended as a ready reference guide to the control and management tactics for the more important plant diseases in the Pacific Northwest. The specific cultural, biological, and chemical recommendations are intended to manage a specific plant disease but may not always be appropriate under all production circumstances. The synthesis of a specific management recommendation should be done by a qualified individual. For this reason, this book should be used by—and has been expressly written for—county Extension agents, consultants, field and nursery people, and chemical industry representatives. Information in this publication is in a state of constant change.
