Invasive Plants, IPM, Pests, and Diseases


Integrated Pest Management (IPM) is a science-based process that combines tools and strategies to identify and manage pests. Pests are any organisms (including plants and animals) that pose health, environmental, economic, or aesthetic risks. IPM provides economic, health, and environmental benefits. IPM practitioners use knowledge of pest and host biology along with monitoring to implement management tactics to 1) prevent unacceptable levels of pest damage; 2) minimize the risk to people, property, infrastructure, natural resources, and the environment; and 3) reduce the evolution of pest resistance to pesticides and other pest management practices.

Delaware Invasive Species Council (DISC) is a non-regulatory organization of nearly 100 scientists, botanists, and ecologists with government, academia, and nonprofit organizations. Its mission is to protect Delaware’s ecosystems by preventing the introduction and reducing the impact of non-native species.

Delaware Native Species Commission was formed by the Delaware General Assembly to implement recommendations made in the final report of the Statewide Ecological Extinction Task Force. Its mission is to: 1) reverse the trend of decline and extinction of Delaware’s local plant and animal native species; 2) work to implement the recommendations of the Statewide Ecological Extinction Task Force; and 3) provide expertise and assistance to state and local lawmakers, policy makers, educators, and other stakeholders.

Delaware Department of Agriculture’s (DDA) Plant Industries Section  aims to prevent the introduction, establishment, or spread of plant and honeybee pests, and suppress, control, abate, or eradicate pests that are dangerously injurious to the agricultural, horticultural, and forestry interests of the state.
