The Arizona Plant Diagnostic Network is designed to link growers and master gardeners with plant experts in your community and with plant scientists at the University of Arizona. These experts are available to answer questions about plant health and help identify new and emerging plant pests and pathogens in Arizona. The goal is to increase public awareness of incoming threats to the plants and produce in our State.

This list of the most serious biotic pests and pathogens is maintained by the State (Arizona Department of Agriculture) and Federal (USDA) regulatory agents. Their goal is to prevent the introduction and/or spread of these pests/pathogens in our state.

Vermont Invasives.

An emerald ash borer (EAB) beetle was detected in a tree located in Londonderry, VT. The mapped area in Vermont (PDF | 1.25 MB) to which "Slow-the-Spread" recommendations apply now covers:

  • All of Londonderry, Windham, and Landgrove;
  • Most of Jamaica, Winhall, Peru, Weston, Andover and Grafton; and
  • Extends into Chester, Townshend, Stratton, Athens, Mount Tabor, and Wardsboro.

October means that non-flight season Recommendations to Slow the Spread of Emerald Ash Borer are now in effect when moving ash from the infested area. With the heating season underway, and firewood deliveries actively occurring, it’s important to remember that untreated ash firewood should never move out of infested areas. Be sure that your purchase or transportation of both log length and split firewood will not unnecessarily spread EAB. There’s a lot of spread to slow: While the infested area map shows that high-risk areas for EAB include many towns, visibly infested trees still remain rare in Vermont. You can help by following the "Slow-the-Spread" recommendations.

These plants are known to be invasive or potentially invasive in Connecticut and are on Connecticut's list of Invasive and Potentially Invasive Plants. They are known to be present only in relatively low numbers at limited locations in Connecticut. These species should be considered for control and eradication efforts in the state when resources are available. If you find these species: Report your findings immediately to the CT Invasive Plant Coordinator at reportinvasives@uconn.edu.

This guide is intended to assist with identification of invasive plants and provide information on controlling these problem plants. Included are both non-chemical means of control as well as information on proper use of herbicides where chemical controls are needed. The choice of control measure depends on the size and nature of the infestation. If dealt with early enough, invasive plant problems can often be eliminated by non-chemical methods. However, a herbicide-based approach may be required to control an infestation that has become well established or widespread.
