Oklahoma Invasive Plant Council.

The Oklahoma Invasive Plant Council has developed a list of invasive plants by region. These plants have invasive qualities and are present in the region or neighboring regions. These are species that are not abundant yet in the area, but should be monitiored, reported and controlled before they become a bigger problem in the state.

Ontario Invasive Plant Council.

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.

A dead spotted lanternfly (SLF), Lycorma delicatula, has been found in a shipment of planters and ceramic pots sent to Oregon from Pennsylvania. Recently, a nursery in the Corvallis area found the dead female specimen and called the Oregon Department of Agriculture (ODA) Insect Pest Prevention and Management Program (1-800-525-0137) to report. The SLF poses a threat to tree fruit and grape production. Grapes used for wine are a high value crop in Oregon, valued at more than $238 million in 2019. This invasive pest also prefers a broad range of more than 70 plant species including apples, cherry, chestnut, hops, maple, peaches, pear, pine, plum, poplar, oak, rose and walnut.

SLF was first found in North America in 2014, in Pennsylvania. It is believed to have arrived on shipments of stone from China. Since then, SLF has been detected in 11 eastern states (Connecticut, Delaware, Massachusetts, Maryland, North Carolina, New Jersey, New York, Pennsylvania, Virginia and West Virginia). If you believe you have found SLF, please notify the Oregon Department of Agriculture immediately by calling 1-800-525-0137 or email plant-entomologist@oda.state.or.us.
